JavaScript - Issue With Passing Variables
ive just started really to develop my javascript out of individual functions and appreciate and help with this. I start outside of the external JS file by:
reviews.init(); reviews.initialiseContent('comment'); This loads my data and loads + sets the comment tab as default. My problem is that in the external JS file (shown below) the loadTabs variable will not allow me to pass it a variable: contentDiv.onclick = this.initialiseContent; Whenever I pass a variable here it errors, am I setting this up correctly, should I be using prototype for my this. variables? Interested to hear back on if this structure of code is the right way to go about this and also how I can pass a variable in this way Thanks, Phil Code: var reviews = new reviews();
var xmlhttp;
var classArray = Array('comment', 'review', 'video', 'stats', 'add');
function reviews(){
/*--------------------------------------------*/
// Setup tab events, rating and thumb content
/*--------------------------------------------*/
this.init = function()
{
/*--------------------------------------------*/
// Load and display tabs
/*--------------------------------------------*/
this.loadTabs();
/*--------------------------------------------*/
// Load and display rating
/*--------------------------------------------*/
this.loadRating();
/*--------------------------------------------*/
// Load and display thumbs
/*--------------------------------------------*/
this.loadThumbs();
}
/*--------------------------------------------*/
// Initialise and populate tab
/*--------------------------------------------*/
this.loadTabs = function()
{
for(key in classArray)
{
var contentDiv = document.getElementById( 'pp-content-tab-' + classArray[key] );
contentDiv.style.cursor = 'pointer';
contentDiv.onclick = this.initialiseContent;
}
document.getElementById('pp-content-tab-add').style.visibility = 'hidden';
document.getElementById('add-review').style.cursor = 'pointer';
document.getElementById('add-review').onclick = this.showElement;
}
this.showElement = function()
{
document.getElementById('pp-content-tab-add').style.visibility = 'visible';
this.id = 'pp-content-tab-add';
this.initialiseContent;
}
this.initialiseContent = function( tab )
{
if( this.id )
{
var tab = this.id.substring( 15 );
}
if( !in_array( tab, classArray ) )
{
var tab = 'comment';
}
for(key in classArray)
{
if( classArray[key] == tab )
{
document.getElementById( 'pp-content-tab-' + classArray[key] ).className = 'pp-tabon';
} else {
document.getElementById( 'pp-content-tab-' + classArray[key] ).className = 'pp-taboff';
}
}
sendrequest( tab, 'loadtab', stateChanged );
}
Similar Tutorialshi, I am building a web app, I have a list of towns and a list of counties as you can see he http://www.mypubspace.com/mobile/#home (best viewed in Safari) What I would like to do is to pass through the Town value as a variable and then change my SQL query based on which town is selected here is the code Code: <!doctype html>
<?php
include "../config.php";
$loggedIn = (isset($_COOKIE['loggedin']) && $_COOKIE['loggedin'] == 'true')?true:false;
$query1 = "SELECT DISTINCT rsTown FROM pubs ORDER BY rsTown asc";
$result = mysql_query($query1);
$town = $_REQUEST['RSTOWN'];
$townpubs = mysql_query("SELECT * FROM pubs WHERE RSTOWN = ".$town." ORDER BY RSTOWN ASC");
$towns = mysql_query("SELECT DISTINCT RSTOWN, COUNT(PUBID) As PubCount FROM pubs GROUP BY RSTOWN ORDER BY RSTOWN ASC");
$counties = mysql_query("SELECT DISTINCT RSCOUNTY, COUNT(PUBID) As PubCount1 FROM pubs GROUP BY RSCOUNTY ORDER BY RSCOUNTY ASC");

Please help! Hi, I hope someone can help me! I have a list of buttons, each with a different id which is taken from the ids of these values from the database. When I click one of the buttons it shows the items that correspond to this id in the database. Therefore, when different buttons are clicked the display changes to match the objects relating to this particular button. When a button is clicked, this shows various other objects which I can then select (using a checkbox). When a checkbox is clicked, a Javascript function is called to change the html text next to the appropriate button. However, I can't get this to work as I need to pass the id of the button, and the html span, to the Javascript in order to change the correct text. Here is my Javascript : Code: function questionnum(checkbox) {
if(checkbox.checked) {
var qdesNumElement = document.getElementById('<?php echo $q;?>');
var qdesNum = qdesNumElement.innerHTML;
qdesNumElement.innerHTML = ++qdesNum;
}
This code only gets the last button. Please help. Hi I want help with trying to pass some variables from one function to another. so with the following example: Code:
// main body of script
function exercise() {
fnLLR_Calculate();
fnLLR_Calculate2();
}
function fnLLR_Calculate() {
//-------Gets values from web page------//
var $Shares;
_set($Shares, _getText(_textbox("CALC_STOCK_INPUT")));
$Shares = Number($Shares);
_log("$Shares =" + $Shares);
var $GrantPrice;
_set($GrantPrice, _getText(_textbox("GRANT_PRICE_INPUT")));
$GrantPrice = Number($GrantPrice);
_log("$GrantPrice = " + $GrantPrice);
var $FMVPrice;
_set($FMVPrice, _getText(_textbox("FAIR_MARKET_VALUE")));
$FMVPrice = parseFloat($FMVPrice).toFixed(2);
_log("$FMVPrice = " + $FMVPrice);
var $TaxWitholdRate;
_set($TaxWitholdRate, _getText(_textbox("TAX_WITHHOLDING_RATE")));
$TaxWitholdRate = $TaxWitholdRate / 100;
_log("$TaxWitholdRate = " + $TaxWitholdRate);
}
function fnLLR_Calculate2() {
//----uses values from fucntion 1 to calculate----//
$Result_Shares = ($Shares- $GrantPrice) * $TaxWitholdRate / $FMVPrice;
$Result_Shares = $Result_Shares.toFixed(0);
_log("$Result_Shares = " + $Result_Shares);
}
So i need to pass some variables from function fnLLR_Calculate to fnLLR_Calculate2. What is the best way to do this? Hi, Need some help here. To formulate the problem simple i have two buttons with the onclick function: Code: <a href="#" ONCLICK="function1('this')">Click for this!</a>
<a href="#" ONCLICK="function1('that')">Click for that!</a>
When I click this button I actually need to pass the value 'this' or 'that' to function2.. Code: <script language="javascript">
var name = ''
function1(name) {
???
}
function2() {
document.all.textbox.value = name;
}
</script>
I guess what im asking is how can you set a variable by one onclick function and then use it in any other function? Thanks a bunch! Col if i have: function someFunction(){ var original = "Original Variable"; anotherFunction(original); } function anotherFuntion(){ /* 1.does the original variable automatically get passed? 2. will var transformed = original + "Transformed" give me a result of "Original Variable Transformed"? 3. Or does it have to be declared in the function: anotherFunction(original) */ } thanks for any help I have a concatenated list of posts like this: Code: <?php
// this generates a list of divs with unique id's as $post_id's
$my_posts .= '
<div class="storypost' . $post_id . '">
<a href="mystorypost.php?id=' . $post_id . '>' . $member_name . ' Post</a>
<a href="#" onclick="DoAction(' . $mem_id . ', ' . $post_id . ');">Remove?</a>
</div>
';
?>
And here is the javascript/ajax, which sends the variables to the _removepost.php, in order to run that code, and delete the post from the database... Code: <script>
function DoAction(mem_id, post_id) {
var r = confirm('Are you sure you want to remove this post?');
if (r == true) {
$.ajax({
type: "GET",
url: "_removepost.php",
data: "mem_id=" + mem_id + "&post_id=" + post_id,
});
$(".storypost"+post_id).hide();
return false;
} else {
return;
}
}
</script>
So, the thing actually works (the post gets deleted from the database). But what does not work, is: 1) the div is not getting hidden via the .hide() 2) after I click the onClick link, the page scrolls back to the top of the page... and I have to end up reloading the page to see the change. I believe there is something wrong with where I placed the "return false;" and something wrong with how I call the variable in .hide(). Hi all, I'm quite new to Javascript, and I'm stuck with a problem here. I have a website, I won't go in to detail, but it generates some javascript code for the user. Well, that's the idea. The user puts this javascript on his or her website. Now everytime the page with that javascript is loaded, a page on my server is called, and is supposed to display something on the place of the javascript of that website. I however have not the slightest clue how to do this. The script on my server has to get some values from a database (I'll be doing this with php). Therefore are some variables needed, like ID's. Those are put in the javascript at the website of that person. (I know they could just change it, but that'd only disadvantage them) And example of the code the person with the website would get is this: (This was also generated on user basis somewhere, which does about the same thing) Code: <script language="javascript" type="text/javascript" charset="utf-8"> var border = '#000000'; id = 1337; </script> <script language="JavaScript" type="text/javascript" src="http://somesite.com/scriptname.php"> </script> If you don't understand what I'm trying to do here, please ask, because I might not've explained it clear enough. Thanks, lordstyx. [edit] Someone said to look in the direction of XMLHttpRequest. I don't really know what that is, but I'll try and find a bit more info about it. I am developing a site that adds multiple dynamic buttons. I would be ideal if the event these buttons trigger could pass a 'variable' (the passed variable is constant with respect to each button). My attempt... myButton.setAttribute("onClick", "myFunction(" + myVar +")"); ...doesn't seem to work. Can anyone help out? I'm new to javascript and have come across what I'm sure its a really easy problem to solve. I want a page with a hyperlink that passes a variable to another 'pop-up' page (in this case a name, its just an example) and new pop-up page prints a message followed by the variable thats passed. Here is the code as it is right now Code:
<html>
<head>
<script language="javascript" type="text/javascript">
function popitup(a)
{
var reply = 'a';
newwindow=window.open('','name','height=200,width=150');
var tmp = newwindow.document;
tmp.write('<html><head><title>popup</title>');
tmp.write('</head><body><p>"Hello there" + reply </p>');
tmp.write('<p><a href="javascript:self.close()">close</a> the popup.</p>');
tmp.write('</body></html>');
tmp.close();
}
</script>
</head>
<body>
<a href="testpopup.html" onclick="popitup('Toby')"
>Link to popup</a>
</body>
</html>
In short, I just want the pop-up page to print 'Hello there Toby' or whatever name I choose to pass across. Any help much appreciated!! The 'testpopup.html' url is just the initial webpage. Hi, There are different ways by which values of variables can be passed between forms. One of the ways is to use the setTimeout to pass the values or data. Here the biggest advantage is we can pass data to a different site even running automatically. I would need from someone a bit of help to pass the variable links from form1 to variable strLink in form2 using SetTimeout. We have the following schema: An options select menu where value of the option, sent with a submitted form, is specified with the value attribute. In the absence of a VALUE attribute, the value is the content of the option element. Quote: <html> <head> </head> <body> <form name="form1" method="get" > <select name="links"> <OPTION VALUE="http://www.as.com/">El Mundo <OPTION VALUE="http://www.atb.com.bo/">El Pais <OPTION VALUE="http://www.cadenadial.com/">Bizgrok <OPTION VALUE="http://www.cadenaser.com/">Eclab <OPTION VALUE="http://elsa.berkeley.edu/">Elsa <OPTION VALUE="http://www.caracol.com.co/">Factfinder <OPTION VALUE="http://fairmodel.econ.yale.edu/">Fairmodel <OPTION VALUE="http://www.cincodias.com/">Village <OPTION VALUE="http://www.continental.com.ar/">Levine <OPTION VALUE="http://www.literature.org/">Literature.org <OPTION VALUE="http://www.literatura.org/Gusman/frasquito.html">Frasquito <OPTION VALUE="http://www.literatura.org/Gusman/villa1.html">Villa <OPTION VALUE="http://www.literatura.org/Gusman/lgcrific.html">Mapa <OPTION VALUE="http://www.literatura.org/Gusman/lgcrific.html">Mapa </select> </form> Timing events. We are executing some code after a specified time-interval. Quote: <script> setTimeout('document.form1.links.value = document.form2.strLink.value',2000); </script> You can see in the below case the values can be posted to another form. Quote: <form name=form2 method=post action="convertx.asp"> <input type="text" name="strLink"> <input type="submit" name="btnSubmit" value="Show"> </form> By post method of form submission we can automatically send more number or length of data using SetTimeout. Quote: <script type="text/javascript" language="JavaScript"> btnsubmit = document.form2.submit(); setTimeout('btnsubmit',2000); </script> Quote: </body> </html> Any help will be much appreciated! Just he! Hi, I am quite new to javascript but I'm quite sure this problem is very easy to solve. I have a vague idea of what might be going wrong but I have no idea what I should be doing instead. Here is what I'm trying to do: User inputs X and Y coordinates into form validate that they are numbers do a little bit of maths redirect to a php script with a single variable tacked onto the end of the url Here is the form code: Code: //part of a larger php script to make the form echo "<form name='gotoForm' onsubmit='return coordCalc()'> <fieldset> <legend>Go to Square</legend> X <input type='text' id='X' size='1' maxlength='3'/> Y <input type='text' id='Y' size='1' maxlength='3'/> <input type='submit' value='Go To' /> </fieldset> </form> "; which references these functions in the header: Code:
//Is it a number
function isNumeric(elem, helperMsg){
var numericExpression = /^[0-9]+$/;
if(elem.value.match(numericExpression)){
return true;
}else{
alert(helperMsg);
elem.focus();
return false;
}
}
//deal with the input, check if they are both numbers with the above function
//if they are do some maths on the input
//add the result onto a url and redirect
function coordCalc (){
var Xcoord = document.getElementById('X');
var Ycoord = document.getElementById('Y');
if(isNumeric(Xcoord, "Please enter a Number for X")){
if(isNumeric(Ycoord, "Please enter a Number for Y")){
//Takes the X and Y coordinates and transforms them into a single number
//not fully coded in case you try putting some numbers into the formula btw :)
var X = parseInt(document.getElementById('X').value);
var Y = parseInt(document.getElementById('Y').value);
var G = 16;
var Z = (((G + 1) - Y) - Y);
var A = (Y + Z);
var B = (X - 1);
var L = ((A * (G - 1)) + B);
window.location = "map.php?start=" + L;
}
}
return false;
}
The number validation works but the url ends up as map.php?start=NaN. Now, this simply must be the way I am assigning the Xcoord and Ycoord variables with the document.getElementByID() function I am sure. But like I said, I have no idea what to do instead, any help is massively appreciated. Thankyou! First off I didn't know whether to post this here or in the PHP section since it deals with both, but mostly JS. I have a PHP scraper that scrapes the job title, company name and location from a website and stores them in separate arrays. These values are then extracted out one at a time from the array and stored into a string, that is then passed to a Google Maps API. I can make this successfully happen once, the thing is I need to do it multiple times. I have an idea on what I should do but don't really know how to implement it (correctly). The idea I had was to create a function in the JavaScript section that accepts three values from PHP. This function would be called in my PHP for loop that extracts the values from the array into a string. The thing that confuses me is that the Map function is called via <body onLoad="initialize()">. Here's the link to my code Afternoon All, I have managed to secure some JavaScript code from another site that allows me to access values from within my Google Analytics cookie: <!-- begin Referer Check --> <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www."); document.write("<script src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'>" + "</sc" + "ript>"); </script> <script type='text/javascript'> var pageTracker = _gat._getTracker("UA-1-1"); pageTracker._trackPageview(); // // This is a function that I "borrowed" from the urchin.js file. // It parses a string and returns a value.

I have tried to pass just the source var from within the <script> tags. document.forms["cforms2"].elements["cf2_field_1"].value = source; I have commented out part of original code that I did not think I needed. Any help that can be offered I would be grateful, ultimately I would like to be able to pass all these values to hidden fields. Thanks Paul Brown Here is the program: http://www.1728.com/newwindow.htm Basically, I want to input a number in the input box, which assigns a number to the variable numval located at document.box1.b1. When clicking on the "new window" button, an alert displays the input box value, then another window opens and displays the integers 1 through 12 and the amount squared. I would like the new window to obtain the number from the previous window so that the new window will display integers (and their squares) from 1 to the value of numval. Hello, I am a newbie at JavaScript programming and I am continuously running into the same error: "the variable is undefined" In the below js code, I am attempting to write a yearly calendar into an html file. I have followed the instructions from a text, and I am fairly certain that I have followed them correctly. From what I can see the problem is that my calendarDay variable is undefined. How can I fix this, and better yet prevent it from happening again? The portion of my JavaScript code that is causing the error is below and once again I really appreciate your feedback ... Code: /* The purpose of this function is to place a monthly calendar within a larger table cell. */
function writeMonthCell(calendarDay, currentTime) {
document.write("<td class='yearly_months'>");
writeMonth(calendarDay, currentTime);
document.write("</td>");
}
/* Insert a function named yearly(). The purpose of this function is to write the entire yearly calendar containing all of the seperate monthly calendars as cells within the larger table. The function has a single parameter named calDate. */
function yearly (calDate) {
if (calDate == null) calendarDay = new Date() // loads the current date and time
else calendarDay == new Date (calDate); // first error "calendarDay is not definded"
var currentTime = calendarDay.getTime(); // retrieves the current time in milliseconds
var thisYear = calendarDay.getFullYear(); // retrieves the four digit value for the year
// the following writes the calendar title
document.write("<table id='yearly_table'>");
document.write("<tr>");
document.write("<td id='yearly_title' colspan='4'>");
document.write(thisYear);
document.write("</th>");

I want to pass 2 variables from a html page and collecting in another html page using javascript. say i pass xyz and abc to a page 2.html from 1.html without using cookies. In 1.html page i have many links. each link should be able to pass different variable to 2.html. when some one clicks on a link the variables should be passed to 2.html I want to know how to collect them and use them. please provide me code snippet. Hello, i'm working on a 3 page survey. When hitting next, previous, or submit it passes the values of all the questions to the next page. I've got the whole thing working correcting except for one thing: When the box is "not" checked it passes no value. I'm needing it to have a value of "1" when checked and a value of "0" when not checked, and currently when its not checked and i pass the info it leaves it blank. I'd post the whole code to one of the pages but it's long , so i'll post the snipits of the code. Code: <script type="text/javascript">
/* <![CDATA[ */
function processQueryString() {
var formData = location.search;
formData = formData.substring(1, formData.length);
while (formData.indexOf("+") != -1) {
formData = formData.replace("+", " ");
}
formData = unescape(formData);
var formArray = formData.split("&");
for (var i=0; i < formArray.length; ++i) {
//document.writeln(formArray[i] + "<br />");
var sDataName = formArray[i].split("=")
switch (sDataName[0]) {
case ".lib_use":
for (var j=0; j < document.getElementsByName(".lib_use").length; ++j) {
if (document.getElementsByName(".lib_use").item(j).value == sDataName[1]) {
document.getElementsByName(".lib_use").item(j).checked = true;
//alert("lib_use set");
}
}
break;
case ".lib_comp":
if (sDataName[1] == 1) {
document.getElementsByName(".lib_comp").checked = true;
document.getElementsByName(".lib_comp").value= 1;
}
else {
document.getElementsByName(".lib_comp").checked = false;
document.getElementsByName(".lib_comp").value= 0;
}
break;
default:
alert("not caught = " + sDataName[0]);
continue;
}
}
}
/* ]]> */
</script>
<input type="checkbox" name=".lib_comp" id="lib_comp" value="1" />
The first case that i showed in my code is a radio button, and it passes correctly, i just wanted to show the "format" i was using in a working sense. The 2nd case is an example of the check boxes. Thanks for looking at this, and giving any suggestions you might have! Hi, I have what I assume started as a simple error and then trying to fix it I think I have made things so complicated I've become confused. I have two fields, a drop down list and a text field, when someone clicks on a value in a drop down list (I will show the results eventually but at the moment) I just want the result to echo in my getCategory.php and the same for the text field. Both php pages are currently being called. And at the moment contain $_REQUEST['category'] and $_REQUEST['ProductName'] respectively. Nothing is being echoed. I know the below code is wrong, but the more I try to correct it the worse it gets so I thought I would just leave it as is before I made it worse. Code: <script type="text/javascript">
function loadXMLDoc1(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);
}

Dear all, I'm passing the variables myTitle and myLink to form.php using javascript. This is the way I'm doing it: Code: <a href='form.php?title=" + myTitle +"&link="+myLink+">Click me</a> It's working great but sometimes myTitle and myLink contain the plus character (+). When this happens it's not passed. In the case of the title, it's just a problem of looks but in the case of the link, well, the link won't work without the character. As an example if the title is: Laptop + Accessories What is passed is: Laptop Accessories What can I do to pass also the plus character?? Thanks a lot!! |
