JavaScript - Javascript Button With 2 Functions And A Css Sprite
Hi
I've set up an html page that contains 3 buttons, which have a sprite rollover effect when hovered over. This is handled by css. When one of the buttons is clicked - a value is passed to an input field. This is handled by Javascript. Both of these functions work. What I would like to do is add a second function when a button is clicked - so that the hover sprite remains selected. Could anyone tell me how to do this please? Here is the button code I have: <button type="button" class="fantasy_button_blue_sprite" id="mcgyver" value="mcgyver" onclick="setHiddenControlValue('option1');">next</button> Here is the input field that gets populated: <input type="<?php echo $type;?>" id="fantasy_friend" name="fantasy_friend" value="<?php echo $fantasy_friend; ?>"> This is the javascript I'm using: <!-- // set the hidden form field when a button is clicked function setHiddenControlValue(selectedValue) { document.getElementById("fantasy_friend").value = selectedValue; parent.document.options_form.their_firstname.value=selectedValue; } And this is the sprite css: .fantasy_button_green_sprite { background: transparent url("/images/align_page/fantasy_button1.jpg") 0 1px no-repeat; height:61px; width:164px; border:none; text-indent:-99999px; cursor: pointer; margin-top:20px; } .fantasy_button_green_sprite:hover { background: transparent url("/images/align_page/fantasy_button1.jpg") 0 -61px no-repeat; } Thanks!

I'm tryingto make a button where, when you click the button, a variable will increase and refresh (reload the number displayed, but one number higher. Here is what I have: Code: <html> <head> </head> <body> <script type="text/javascript"> x=1 document.write(x) </script> <input type="button" value="Up" onclick="document.write (++ x) "> <input type="button" value="Down" onclick="document.write (-- x)"> <input type="button" value="Reload" onclick="history.go(0)"> </body> </html> The problem with this is: When you hit the "up" button, everything on the page dissapears and it just outputs "2". All the buttons and stuff dissapear? There must be a better way to do it. And would I need to use a database. Any help? Hey, I have a page at http://www.webdev70.cocc-webdev.org/contact.html where I have styling on the radio and check boxes. I'm working on another project for class now where I want onclick or onchange functions in the radio buttons. When the radio buttons have the class="styled" on them, the function will not execute. When that's removed, they do. Here is the javascript for the styling: Code: var checkboxHeight = "25";
var radioHeight = "25";
var selectWidth = "190";
document.write('<style type="text/css">input.styled { display: none; } select.styled { position: relative; width: ' + selectWidth + 'px; opacity: 0; filter: alpha(opacity=0); z-index: 5; } .disabled { opacity: 0.5; filter: alpha(opacity=50); }</style>');

The code is way over my head so I'm not sure where the problem is, or if it could be fixed. This is what one of my radio buttons looks like: <input type="radio" name="puppy" value="1" class="styled" onchange="puppycheck()">Black and White Puppy If the style tag is removed it works perfectly. There is CSS too, but I don't think the problem is in there. Hi, This button changes the button text when clicked, but it is always calling the same function. How to make the button depending on the button text to call different functions on onclick? [CODE] <script type = "text/javascript"> function button_switch(){ if (document.switch_form.switch_b.value == "Adam"){ document.switch_form.switch_b.value="Eva"; } else{ document.switch_form.switch_b.value = "Adam"; } } </script> <form name = "switch_form"> <input type = "button" name = "switch_b" id = "switch_b" value = "Adam" onclick = "button_switch()" /> </form> [CODE] Hey guys. This is vague because I dont know what exactly to tell you but please reply with me so I can fix this. I want to add something to my forum. Specifically, I want to add a HTML and Picture button for when you go to reply. Like posting an article here, there are also these options (font, alignment, insert image) I do not know how to achieve this but shouldnt be too hard. Here are the two sources you will need to look through to help me fix the forum. http://neoweather.com/FWFORUM.JS http://static.websimages.com/JS/fw.js THANKS Hi, I am not entirely sure what I am doing wrong here, and I have been looking at this for ages, so apologies in advance if I have become so bleary eyed I can't see something simple. I use php to create buttons based on values pulled for a table. The problem I have is when you click on the first button the javascript function works great, when you click on the next button you get the same output even though it should be different results. I am working in ff and I can see on my firebug console that the javascript function is being called, but it is not passing the new value of the second or third button, it just keeps repassing the value of the first button. So not entirely sure where I am going wrong here. My page is: Code: <script type="text/javascript">
function loadXMLDoc2(File,ID,Msg){
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
}
else {
try{
xmlhttp=new ActiveXObject("Msxml2.XMLHTTP");
} catch (e) {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(ID).innerHTML=xmlhttp.responseText;
}
}
var params=Msg;
xmlhttp.open("POST",File,true);
xmlhttp.setRequestHeader("Pragma", "Cache-Control:no-cache");
xmlhttp.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xmlhttp.setRequestHeader("Content-length", params.length);
xmlhttp.setRequestHeader("Connection", "close");
xmlhttp.send(params);
}
</script>
<head>
<body>
<?php
$con = mysql_connect("localhost","user","password");
if (!$con) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db("mydb", $con);
$result = mysql_query("SELECT DISTINCT theme FROM goods WHERE category='{$_POST['category']}'
ORDER BY theme DESC");
while($row = mysql_fetch_array($result)){
echo '<input type="text" class="hidden" name="theme" id="theme" value="' . $row['theme'] . '" ><input type="button" class="button3" name="product" id="product" value="' . $row['product'] . '" onClick="loadXMLDoc2(\'getShow.php\',\'txtHint\',\'theme=\'+encodeURI(document.getElementById(\'rtheme\').value))" > ';
}
echo '<br /><br />
<div id="txtHint"><div>
<br />
<br />';
mysql_close($con);
?>
And getShow.php produces a table with a list of product images, names and prices, based on theme. So basically not sure where I am going wrong here? Okay, here is my assignment: reate an HTML document with 2 JavaScript functions as described below. Call the document useparameters.html The first function will use a parameter for the Width of a horizontal rule. When called, the function will draw a horizontal rule of a width specified by the Functions argument. Prompt the user for the pixel width information. The second function will use parameters for two heading sizes. The parameters will be used for the size of the text that will be displayed on the first line and the size of the text that will be displayed on the second line. The heading size will be different on the first and second lines. Prompt the user for these two headings as well (one prompt for each). The body of the HTML document will contain a page heading and call the two functions you created, displaying a horizontal rule and two lines of text which will be formated based upon the parameters the user entered into the prompts. Here is my code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <title>Use Parameters</title> <script type="text/javascript"> <!-- var hrsize var htwosize var psize function bar() { hrsize = window.prompt( "Please enter the size you want your horizontal rule to be (in pixels)", 50 ) hsize = hrsize document.write("<HR ALIGN='left' width=" + hrsize + ">"); } function output() { htwosize = window.prompt( "Please enter the size you want your heading to be (in pixels)", 18 ) htwosize = htwosize document.write("<h2" + htwosize + "/h2>") } function output() { psize = window.prompt( "Please enter the size you want your paragraphcs to be (in pixels)", 12 ) psize = psize document.write("<p" + psize + "/p>") } --> </script> </head><body> <script type="text/javascript"> <!-- bar(hrsize) output(htwosize) output (psize) --> </script> <h2>JavaScript Rules!</h2><p>Using JavaScript is fun! </p> <p> This is some standard HTML, unlike the above which was generated with javaScript.</p> </body> </html> What am I doing wrong? Forgive me if the code is rather bad, I am new to Javascript. Now what I'm aiming to do is after I have entered the contents of the Array's I then want to query the newly created array/database, based on the track number, Via a seprate function. However all the values I entered, always come up empty. No matter how many solutions I tried I can't get the query to work. So I've decided to come to you guys/gals for help. Code: mainMenu()
function mainMenu()
{
menu = 0;
menu = eval(prompt("Select an Operation to Continue\n ====================\n 1 - Create new Database\n 2 - Query Database\n 3 - Show Report\n Any other to exit"));
switch (menu)
{
case 1:
insert(trackNumber)
break;
case 2:
query(trackNumber)
break;
case 3:
break;
}
}
// Enter the track number
function trackNumber()
{
var theNumber = eval(prompt("Enter Track Number"));
if ((theNumber >= 0) && (theNumber < 100))
{
return theNumber; // Stores the track number for insert(trackNumber)
}
}
// This function will allow the user via the (trackNumber)
// parameter to insert the contents of the database
function insert(trackNumber)
{
// Create new Array's
trackNum = new Array(5)
trackName = new Array(5)
trackArtist = new Array(5)
// For each Track we want to hold the trackNumber(),
// the track name and the track's artist.
for(var i = 0; i < trackNum.length; i++)
{
trackNum[i] = trackNumber()
trackName[i]= prompt("Enter Track Name: " + i)
trackArtist[i] = prompt("Enter Track Artist: " + i)
}
}
// This Function will allow the user to query the database, based on track number.
function query(trackNumber)
{
var trackSearch = trackNumber()
var j = 0;
for(j in query)
{
if (query[j] == trackSearch)
{
alert("Track Number: " + trackSearch + "\nTrack Name: " + trackName[j] + "\nTrack Artist " + trackArtist[j]);
break;
}
else if (query[j] != trackSearch)
{
alert("Track Number: Empty" + "\nTrack Name: Empty" + "\nTrack Artist: Empty");
break;
}
}
}

I am trying to create a difference function which would work out the difference between two numbers. e.g. 14 and 18 I am able to create a function and if statement to find the larger number of a argument but am having trouble writing one to find the difference between two numbers. Iam also confused (i know probably a silly question) but is the operator used the same for this function. Hope people can make sense of that. Thanks, Hello all here is a more intelligent question. This one is just on an exercise I am doing. I have to call a function using parameter values. my main function is this Code: function showResults(race,name,party,votes) or just function showResults in the next lines below i have to call the function is this the right way Code:
<script type="text/javascript">
{
showResults=("race[0],name1,party1,votes1");
}
</script>
or should it be without the { and } like this? Code:
script type="text/javascript">
showResults=("race[0],name1,party1,votes1");
</script>
or is it like this Code: script type="text/javascript">
showResults(race[0],name1,party1,votes1);
</script>
Thanks all, what would be the proper method Thanks All -- I have a JavaScript config file called gameSetting.js which contains a bunch of variables which configures a particular game. I also have a shared JavaScript library which uses the variables in gameSetting.js, which I include like so: <script type="text/javascript" src="gameSetting.js" ></script> <script type="text/javascript" src="gameLibrary.js" ></script> In gameSetting.js I have: $(document).ready(function() { // call some functions / classes in gameLibrary.js } in Firefox, Safari, and Chrome, this works fine. However, in IE, when it's parsing gameSetting.js, it complains that the functions that live in gameLibrary.js aren't defined. When it gets to parsing gameLibrary.js, the variables in gameSetting.js are reported as not being defined. I've tried dynamically bootstrapping the gameLibrary file using this function in document.ready for dynamic load... $.getScript("gameLibrary.js"); However, the same problem still happens in IE, where when it parses the files individually it's not taking into context the file/variables that came before, so it's not an out of load order problem. My options a 1) collapsing all the functions in gameLibrary.js and variables in gameSetting.js into one file. However, this is not practical because this is dealing with literally hundreds of games, and having a gameLibrary.js in ONE location for ONE update is what makes most logical sense. 2) figure out a way to get this to work where variables in file1 are accessible to file2 in IE (as it seems they are in other browsers). jQuery seems to be able to have multiple plugins that all refer to the based jQuery-1.3.2.js, so I know there is a way to get this to work. Help appreciated. Nero Hi, i was wondering if there was a way to call a nested javascript function directly, from outside of the function its nested in? for example, if i have the following functions: Code: <script type="text/javascript">
var test = function(){
var testInner = function(){
alert('testInner');
}
}
</script>
can i then call the 'testInner' function directly from an onclick action something like this: Code: <a href="#" onclick="test.testInner()">TEST JS</a><br /><br /> That code is obviously not working for me, but is there something similar to what ive shown here that will work? Thanks in advanced Hey guys, I'm using javascript in a menu to change the colour scheme of a page with frames and wondered how I could make this Javascript work across frames. The top frame is the colour picker with the Javascript and the bottom frame is the html template that will be changing colour scheme. JS: Code: var cols = {
red: [
{ el: '.headertitle', color: '#FF0000' },
{ el: '#wrapper #maincontent #leftpanel ul.leftnavigation li a.current', bgcolor: '#FF0000', color: '#FFFFFF' },

<div class="choosecolour" id="cborange" style="background-color: #ff8c10;" onclick="changeColour('orange');"></div>
</div>
Anyone know how I can make the colour scheme of page in lower frame change when colour is picked in top page frame? hey all, I am now at the point of being able to see the light at the end of the tunnel (woot!). After a lot of help from you guys I have tackled my RSS feed issue (sort of) to the point where i have a page that does basically what I need it to (http://www.the-rational-investor.com/test042311.php/). I now need to incorporate this java script developed into the big picture and of course, there seems to be problems. Since I know it works on its own, I must be running into problems getting all the functions working simultaneously and I once again need to call on the board's brilliance in figuring out what I am doing wrong....so here it goes I have taken out a lot of unnecessary code just to focus on the java script. Yes there is PHP code embedded but please don't beat up on me too much for that. here is the main page code: Code: <head>
<?

showRSS(rssfeedvar);
}
</script>

Thanks again for all your wonderful help and all the best to you and your families on this Easter weekend, Brian Hello, I am new to javascript and have managed to create the below form with few fields validation that is working. I also have an email format validation function which is not working. Any help would be hightly appreciated. Below with the form with the javascript <html> <script language="JavaScript" type="text/javascript"> <!-- var radio_selection=""; function checkform ( form ) { **// ** START ** **if (form.name.value == "") { ****alert( "Please enter your name." ); ****form.name.focus(); ****return false; **} if (form.Phone.value == "") { ****alert( "Please enter your phone number." ); ****form.Phone.focus(); ****return false; **} **if (form.email.value == "") { ****alert( "Please enter your email." ); ****form.email.focus(); ****return false; } if (radio_selection=="") { alert("Please indicate your attendance."); return false; } *// ** END ** **return true; } function checkEmail(form) { if (/^\w+([\.-]?\w+)*@\w+([\.-]?\w+)*(\.\w{2,3})+$/.test(form.email.value)) { return true; } alert("Invalid E-mail Address! Please re-enter."); return false; } //--> </script> <body> <form style="font-family:lucida calligraphy;font-size:120%;color:maroon" action="invitees.php" method="post" onsubmit="return checkform(this);checkEmail(this.email.value);"> <table cellspacing="5" cellpadding="5" border="0"> <tr> <td valign="top" > <style="font-family:lucida calligraphy;font-size:100%;color:maroon">Name: </td> <td valign="top"> <input type="text" name="name" id="name" size="40" value="" /> </td> </tr> <tr> <td valign="top"> Phone Number </td> <td valign="top"> <input type="text" name="Phone" id="Phone" size="40" value="" /> </td> </tr> <tr> <td valign="top"> Email Address: </td> <td valign="top"> <input type="text" name="email" id="email" size="40" value="" /> </td> </tr> <tr> <td valign="top"> Will You Attend </td> <td valign="top"> <input type="radio" name="Attendance" id="Attendance_0" value="Yes" onClick="radio_selection='yes'" /> Yes <input type="radio" name="Attendance" id="Attendance_1" value="No" onClick="radio_selection='no'"/> No <input type="radio" name="Attendance" id="Attendance_2" value="Maybe" onClick="radio_selection='maybe'"/> Maybe<br/> </td> </tr> <tr> <td valign="top"> Adults <select name ="adults" id="Adults" > <option>0</option> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> <option>10</option> </select> </td> <td valign="top"> Kids <select name="kids" id="Kids" > <option>0</option> <option>1</option> <option>2</option> <option>3</option> <option>4</option> <option>5</option> <option>6</option> <option>7</option> <option>8</option> <option>9</option> <option>10</option> </select> </td> </tr> <tr> <td valign="top"> Post a Note </td> <td valign="top"> <textarea name="Note" id="Note" rows="6" cols="35"></textarea> </td> </tr> <tr> <td colspan="3" align="center"> <input type="submit" value=" Submit Form " /> </td> </tr> </table> </form> </html></body> I am currently designing a table as such Code: ___________________________ | TABLE | | | FRAME A |___________________________| | last row clicked | FRAME B |___________________________| the top frame is a table and the bottom frame contains the last row clicked called through onclick. question: if frame B is a php file with a javascript object, how do i call the javascript object's function to print the data? here is what i have so far index.html //this is the source code for the site Code: <html> <frameset rows = "60%, 40%"> <frame src = "table_driver.php" name = "A" id = "FRAME1"> <frame src = "bottom_row.php" name = "B" id = "FRAME2"> </frameset> </html> printJSTable() //prints the table shown in frame A Code: function printJSTable()
{
echo '<script src = "java_script.js"></script>';
echo '<script src="sorttable.js"></script>';
echo '<table class = "sortable" id = "myTable" border = "1">';
echo '<thead id = "header"><tr>';
foreach($this->columns as $header => $order)
{
echo '<th>';
echo $header;
echo '</th>';
}
echo '</tr></thead><tbody>';
$counter = 0;
for($i = 0; $i < $this->numRows; $i++)
{
//IMPORTANT changeRow(this) is JS call
echo '<tr onclick = "changeRow(this)" onmouseover = "mouseOver(this)" onmouseout = "mouseOut(this)">';
foreach($this->data[$i] as $key => $value)
{
echo '<td>';
if($value!="")
echo $value;
else
{
echo '';
}
$counter++;
echo '</td>';
}
echo '</tr>';
}
echo '</tbody></table>';
echo '<form><input id = "'.$this->numRows.'"type = "button" value = "add row" onclick = "addRow(id)"></form>';
}
and this is changeRow(this) which is supposed to create the table in frame b Code: //populates headersArr and rowArr correctly parent.B.obj = new TableData(headersArr, rowArr); parent.B.obj.printTable(); here are the function definitions for TableData Code: function TableData(headers, row)
{
this.headerArr = headers;
this.rowArr = row;
}
TableData.prorotype.printTable = function()
{
for(i=0; i<this.headerArr.length; i++)
{
document.write('<tr><th>');
document.write(this.headerArr[i]);
document.write('</th><td>');
document.write(this.rowArr[i]);
document.write('</td></tr>');
}
}
and then, finally, this is the php file for the bottom frame Code: <html> <head> <link rel = "stylesheet" type = "text/css" href = "style.css"/> <script type = "text/javascript" src="java_script.js"></script> </head> <body> <script> obj = new TableData; </script> </body> </html> what i want to do is populate the variable obj from ^ (bottom_row.php) and then use the print function to print it out. right now it is populating correclt,y but i cant get it to print. The error console says that Value undefined (result of expression parent.B.obj.printTable) is not object. ?? sry for all the code! just didnt want to leave anything out thanks! Hello folks: I've got an html table populated by a php foreach routine. One field in this table is an Input type=checkbox. The goal is to run a javascript function when the user checks the checkbox. But, since the checkbox is in a table populated by a foreach routine, I'm having some problems. Below is the applicable code for my table: <?php foreach($results as $row) { $bk_owner = $row['BookOwner']; $addrss_owner = $row['AddressOwner']; $f_name = $row['FName']; $l_name = $row['LName']; $email = $row['EmailAddress']; $d_phone = $row['DeskPhone']; $ext = $row['Ext']; $cell = $row['CellPhone']; $title = $row['Title']; echo "<tr>"; echo "<td class='a'>".$l_name ."</td>"; echo "<td class ='a'>".$f_name ."</td>"; echo "<td class ='c'>".$email ."</td>"; echo "<td class ='a'>".$d_phone ."</td>"; echo "<td class='b'>".$ext."</td>"; echo "<td class='a'>".$cell."</td>"; echo "<td class='c'>".$title."</td>"; echo "<td class='b'><input type='checkbox' id='chk_Bx' value=". $addrss_owner. " onClick='selectFunction()'></input></td>"; echo "</tr>"; } echo"</tbody>"; ?> Specifically, note this line: echo "<td class='b'><input type='checkbox' id='chk_Bx' value=". $addrss_owner. " onClick='selectFunction()'></input></td>"; the value is set to $address_owner. This value is a primary key value and will allow me to run routines related to the record chosen when the checkbox is checked. Following is the javascript code for selectFunction(): function selectFunction(){ var check = document.getElementById("chk_Bx").checked; var val = document.getElementById("chk_Bx").value; alert(val); } At this point the javascript is very simple. All I'm trying to do is pick up applicable values for the record selected. But - I believe because the table is populated through a foreach loop, the javascript alert is returning the same primary key value for every record checked (or unchecked). Also, if I alert out check, it continually returns false, even if I've checked the box and it should read true. I am assuming this is also related to the foreach table presentation. How do I grab ONLY the primary key value, or checked true/false for the applicable record? Thanks in advance: Pavilion Hi all, I've written the following script: Code: <!doctype html>

Now, I could write a version of the keypress function for each rectangle, but that seems like poor coding. Can anyone point out how I might restructure the function or the code so that I can pass the number in the onClick to the rectangle it refers to? Thanks Hi, I am trying to write a script to get my sprite to move to the next row once it reaches the last frame on it's current row. Here's my attempt so far; in the code below I want bird2 when it reaches frame 3 and spState(1) - this means first row - to switch to spState (2) second row. Code: if ($('#bird2'['current_frame']) == 3 && $('#bird2').spState(1)) {
$('#bird2').spState(2);
} else {
$('#bird2').spState(1);
}
Here's the code regarding the spState() Code: spState: function(n) {
$(this).each(function() {
// change state of a sprite, where state is the vertical
// position of the background image (e.g. frames row)
var yPos = ((n - 1) * $(this).height()) + 'px';
var xPos = $._spritely.getBgX($(this));
var bp = xPos + ' -' + yPos;
$(this).css('background-position', bp);
});
return this;
this is from http://www.spritely.net/ you will notice on this site that if you drag the slider to the left the bird sprites change direction, in fact they play the second row of frames. The reason I want my bird sprite to go automatically to the next row is because I am using video turned into individual frames and a png strip, and I am limited by the max width of png (8192px). see http://www.cranihum.com/ scroll down to see the bird on the rooftop. Each frame in that bird sprite is 80px wide and there are 93 frames. So I would like to include multiple rows to allow me to increase the number of frames. Up to 15 rows will be needed and after the last row it should go back to the first row. Perhaps a switch statement would be better than what I currently have. I am new to JavaScript and have been trying to pick up clues from http://www.w3schools.com I am very happy to learn and I hope to be prompted and pushed in the right direction. I hope my request is clear, please ask questions if not. Thank you Will |
