JavaScript - Problems With Html/javascript Variables
I cant figure out how to get the value of a name inputed in HTML into the following script...
<!DOCTYPE html> <html lang="en"> <head> <meta charset="utf-8"> <meta name="generator" content="CoffeeCup HTML Editor (www.coffeecup.com)"> <meta name="created" content="Sat, 10 Sep 2011 19:40:31 GMT"> <meta name="description" content=""> <meta name="keywords" content=""> <title>Enter golfers name</title> <!--[if IE]> <script src="http://html5shim.googlecode.com/svn/trunk/html5.js"></script> <![endif]--> <SCRIPT LANGUAGE="JavaScript" type="text/javascript" src="script1.js"></SCRIPT> <SCRIPT LANGUAGE="JavaScript"> function GetPage(){ document.write("OK") <!-- var fullname = "david park" var lab = ""; var result = fullname.toUpperCase(); var word=result.split(" "); fname = word[0] lname = word[1] alpha = lname.slice(0,1); lab = fname.concat("_") lab = lab.concat(lname) if(word[2]){ ext = word[2] lab = lab.concat("_") lab = lab.concat(ext) } var intro = "./Stats_"; page = intro.concat(alpha); page = page.concat("_golfers.html#"); page = page.concat(lab) document.write(page) <!-- window.location.pathname = page } </script> </head> <body> <center> <form action="form_action.asp" method="get"> You can enter the golfersname or select him from the above list.<br><br> <input type="text" name="fullname" /> <button type="submit" onclick="GetPage()">GO</button> </form> </center> <BR><BR><BR> This is the end </body> </html> Similar Tutorialsso i have a navigation bar and instead of clicking on it to another page on the site where everything reloads again i want it to just reload the content area, so i have 5 tables of content each representing a different page and i just want it this way so i can implement something else that doesnt have anything to do with this Code: <script type="text/javascript">
var page = 1;
function setPage1()
{
page = 1;
}
function setPage2()
{
page = 2;
}
function setPage3()
{
page = 3;
}
function setPage4()
{
page = 4;
}
function setPage5()
{
page = 5;
}
function setBlank1(x)
{
if (page==1)
{
x.class="content";
}
else
{
x.class="blank";
}
}
function setBlank2(x)
{
if (page==2)
{
x.class="content";
}
else
{
x.class="blank";
}
}
function setBlank3(x)
{
if (page==3)
{
x.class="content";
}
else
{
x.class="blank";
}
}
function setBlank4(x)
{
if (page==4)
{
x.class="content";
}
else
{
x.class="blank";
}
}
function setBlank5(x)
{
if (page==5)
{
x.class="content";
}
else
{
x.class="blank";
}
}
this is my javascript so whats supposed to happen is when someone clicks a link on the nav bar it sets the page to that value so only that value is showing. i put the functions setPage1-5 in class="setPage1(this)" according to what content area they go too Code: table.blank {
display: none;
that is my blank class attribute so its not there but its loaded please ask me any questions and sugest anything im not a javascript expert or anything of that sort but ive been looking this over for a couple days now and i cant find anything online either I have been working on a few budget scripts that I can access from the web in using HTML. My problem is that when variable values change I need to change these values in all of the HTML files on the server. I know that there is a way to declare global variables in a single file and use those values in another file but I have not been able to find any information that tells me exactly how to do this. I have tried to put it together on my own using what little informaiton I have been able to find but have not been able to get this to work. Is there a more detailed referance that I can find somewhere or does anyone know what steps I need to take to make this happen?
Hi, I have the following code snippet: test.html ====== <script language="javascript" type="text/javascript"> var testVariable = "test"; </script> <script language="javascript" type="text/javascript" src="test.js"> </script> test.js ===== var testVariable = window.top.testVariable; In firefox, I'm able to access testvariable defined within test.html in test.js. But in chrome, test.js couldnot get the window.top.testVariable field defined in test.html. Can any one please let me know how i can make it work in chrome?. Am i missing something here?. can anyone tell me why this doesn't work please: <html> <head> </head> <body> <input type="hidden" name="ba1r1c1" value="hello"> <script language="text/javascript"> ba1r1c1.value = "goodbye"; document.write(ba1r1c1.value); </script> </body> </html> 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 I am perplexed about this one. Not sure if php is the best solution or maybe javascript. ( or both.) I am writing a litle script that will go to my mysql table and take out 20 rows ( from about 10,000 rows ) based on the WHERE statement. Then I want to step through these 20 rows displaying just two filds in this fashion: First, I want to display one field in a "box" ( using divs and css ) then wait for a form input. Then while keeping the first displayed box and field display the second field in a similar box a fee lines below. Wait for a form input update some data. Then onto the next row. If I use javascript then I could keep all the processing on one page and not have to have server refreshes. But how do I get these those array elements from $row['field1'] and $row['field2'] into javascript vars ? Is this the best way to do this ? Or would php and having a couple of extra trips to the server for form processing be better ? Thanks for any input. . Hi, Ive got a iphone based website im writing in html/javascript, it all works perfectly well apart from an issue with a javascript variable and i cant figure out what im doing wrong At the start of the code i declare a variable var jpgname='blank'; - its blank for testing I then have a href which attempts to change this variables value when clicked <li class="flip"><a onClick="jpgname='test'" href="#page">Cars</a></li> If i replace the jpgname='test' with confirm('test) i get a popupbox so i know its running this code under my #page section (just a div named section) i have [<h1><script>document.write(jpgname);</script></h1> however this always has the value 'blank' Im sure im doing something stupid but im not sure what Any help gratefully recieved thanks Mike Hi, I'm looking to use the document function in javascript to change the TYPE of an INPUT. However I want to change the TYPE of the INPUT according to a variable passed to the javascript button, so i use: document.formname.inputname.value="newvalue"; I want to be able to change what inputname is depending on what is passed to the function, but right now firefox is telling me that it's undefined. Is there any way I can do this? Thanks in advance, Daniel Currently I have the following script:- Code: function validate_form(){
if(regform.reguser.value == ""){
alert("Please completed the selected box");
regform.reguser.focus();
return false;
}else if(regform.regemail.value == ""){
alert("Please completed the selected box");
regform.regemail.focus();
return false;
}else if(regform.regpass1.value == ""){
alert("Please completed the selected box");
regform.regpass1.focus();
return false;
}else if(regform.regpass2.value == ""){
alert("Please completed the selected box");
regform.regpass2.focus();
return false;
}else{
return true;
}
}
to validate a simple registration form, however I initially tried to streamline this function by cycling through an array using a loop to point to various input elements in the HTML page itself. I found that when trying to use a variable in the aforementioned if statements the javascript failed to work i.e. Code: var test = "reguser";
if(regform.test.value = ""){
}
I know the javascript is looking for the input element "test" instead of "reguser" but is there any way I can force it to look for the contents of the variable. Hi all, Rookie (extremely) programmer here, so be gentle Trying to build a little tool here.. Code: <html>
<body>
Artist ID: <input type=TEXT id=ArtistID name= ArtistID value="Artist ID">
<SELECT>
<OPTION value="http://URL.com/EditUser/"ArtistID.value".html">Edit User</OPTION>
<OPTION value="http://URL.com/EditArtist/"ArtistID.value".html">Edit Artist</OPTION>
<OPTION value="http://URL.com/Subscruptions/"ArtistID.value".html">Subscriptions</OPTION>
<OPTION value="http://URL.com/ControlRoom/"ArtistID.value".html">Control Room</OPTION>
</SELECT>
<input type="submit" value="Chyeah">
</body>
</html>
Yeah. Like I said. Rookie. I'm trying to save the input and pass it into the URLs that are the option values. So Artist ID being 111 would take you to url.com/<WHATEVER OPTION YOU CHOSE FROM DROP DOWN>/111 What am I doing wrong/What am I not doing? ps if this is in the wrong forum, sorry! Feel free to move it. Couldn't decide if this should go in DOM forum or not (probably bc I don't know what DOM is!) Hi all, I'm a javascript newbie and having some trouble with what I imagine it s a very basic issue! I am trying to declare a variable inside a function and use it later on in my code... but it just already returns white space... i.e. not variable value. I am setting it within this function: Code: function show_video1(){
document.getElementById('video1').style.display="block";
var video1Name = "Education World News (Part 1)";
document.getElementById('video2').style.display="none";
document.getElementById('video3').style.display="none";
document.getElementById('video4').style.display="none";
document.getElementById('video5').style.display="none";
document.getElementById('video6').style.display="none";
document.getElementById('video7').style.display="none";
document.getElementById('video8').style.display="none";
document.getElementById('video9').style.display="none";
document.getElementById('video10').style.display="none";
document.getElementById('video11').style.display="none";
}
and trying to call it later on with this: Code: <script type="text/javascript">document.write(video1Name)</script> It might be worth noting that each one of my 11 videos will hace a different name. Can anyone help out a newbie? Many thanks, greens85 How can I have global variables and global arrays whose value(s) can be modified and accessed by all the Javascript functions in my HTML document as well as by the HTML code? Thank You CGG Hi, in PHP I can assign a variable do... PHP Code: function setvar($anyvar,$val){ $$anyvar=$val; } setval('myvar',$whatever); how to do in javascript ... I thied window.anyvar= and this[anyvar] and several other combinations but no joy Edit: fixed, my bad, was being a muppet, was calling setvar(varname,val) instead of setvar('varname',val); 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 is it possible to compare 2 php variables with javascript and hide-show a div according to the result? lets say php variables are Code: $a $b and if ($a > $b) show the div can anyone please help me to do this? Sorry for language errors Thanks Hi, I am using javascript to collect hidden form elements and then send the values to a php page, without reloading or changing the page. Basically i have a list of job vacancies, with just an apply button, when a person clicks on the apply button, the form collects some information from their account and sends it using the javascript code. Now this works fine, except for if somebody then clicks on the second job it sends the information from the first form again. And it seems to remember the information. What i am trying to find out is it possible to have multiple forms on one page which once submitted send variables to javascript which then send them to a php but clear themselves so that it doesn't remember the previous values. Here is the code for the form: Code: <form id="submit" method="post">
<fieldset>
<input type="hidden" name="usern" id="usern" value="php variable" />
<input type="hidden" name="joborder_id" id ="joborder_id" value="php variable" />
<input type="hidden" name="site_id" id ="site_id" value="php variable" />
<button class="button positive">Apply For This Job </button>
</fieldset>
</form>
<div class="success" style="display: none;">Your Application has been sent.</div>
</form>
And the Javascript code is he Code: $(document).ready(function(){
$("form#submit").submit(function() {
// we want to store the values from the form input box, then send via ajax below
var usern = $('#usern').attr('value');
var joborder_id = $('#joborder_id').attr('value');
var site_id = $('#site_id').attr('value');
$.ajax({
type: "POST",
url: "apply.php",
data: "usern="+ usern +"& joborder_id="+ joborder_id +"& site_id="+ site_id,
success: function(){
$('form#submit').hide(function(){$('div.success').fadeIn();});
}
});
return false;
});
});
Any ideas or suggestions would be appreciated, Thanks Lee Hello Im using javascript and cookies to send to another page in my site some variables In the other page i recieve them like that : Code: <script language="JavaScript">

}//ends diplay FOR
}//ends widget display

Now my question is ....(and this is the php - sql question) how can i make the variable the i passed to stay a variable , e.g. variable page 1: id=123 *i entered the number 123 into the cookie variable page 2: now this page will show me ALL the array ( 123...134...156...etc...) but i dont want it to print it on the screen i just want to get variables that i can use php-mysql e.g. $id=123 in order to print the specific data from my data base hope u got it.... Danny I am about to translate some C++ code to JavaScript. In C++, it is straightforward to declare and use a Boolean variable; all I do is swap it between true and false and back again as needed. For example, Code: // C++ Code . . . bool na = 1; . . . na = !na; . . . I am wondering if JavaScript offers boolean variables. As far as I know, it does not, but I thought I would confirm by asking around. At the moment, I am planning to code the comparable block in Javascript using an "if" statement or a ternary operation. For example, Code: JavaScript Code . . . var na = 1; // Option 1 if (na) na = 0; else na = 1; // Option 2 na = ((na) ? 0 : 1); . . . Is one of these options recommended as the best way to simulate a boolean variable and operation? (I would like the fastest-executing code possible.) Or is there another--better--way to do it? All advice and recommendations appreciated. Thank-you in advance. I have jQuery like: jQuery(".forms_1_1").validate({ rules: { inputname1: { required: true, }, or inputname1: { required: "Requested field!.", }, Is it technically possible to add 1. PHP variable like $_SESSION and 2. Smarty variable into Javascript like {$global.variable1} inputname1 is value for each variable (PHP, Smarty). Need help how to include variable values into Javascript code. |
