Here's the problem: I have several hidden divs containing information. When you click on a link, javascript executes which is supposed to move the appropriate info from one of the hidden divs into the visible 'body' div. The javascript isn't working, though, and I'm getting 'undefined' instead

None of my getElementById (or other) references produce anything but "undefined." This occurs in the latest versions of Fx, IE, Chrome, and Safari, so it must be something I am doing but not not seeing here. I have boiled it down to the following without success, and wonder whether there is some add on interaction. Fx 3.6.12 has the problem with this code:
<code>
<html>
<head>
<title>This is a test of getElementById</title>
</head>
<body>
<div id="area" name="area_name">xxx</div>
<script type="text/javascript">
var divs = document.getElementsByTagName('div');
var msg = '';
msg = 'Divs[0] contains ' + divs[0] + ' with width = ' + divs[0].width + "
";
msg +='Test area width by id = ' + document.getElementById('area').width + "
";
msg +='Test area width by name = ' + document.getElementsByName('area_name').width;
alert(msg);
</script>
</body>
</html>

I have a table with td consisting of lists with <select></select>. When
I do a document.getElementById("element").innerHTML I don't see the
selected item. IOW, the innerHTML is not dynamic. Is there some way to
get the most recent selected without traversing through the list's
options.
I am trying to have the user input data into a box on a form and when they press an "Add" button, what they typed in the input field should appear in a box below. I can get it to to work....slightly. What they typed pops up where it should be, but then it disappears. Here is the javascript code and the form code:

I have this function which works great in Firefox, but doesn't work in IE. I can make it work in IE by breaking it in Firefox, but I'd like it to work in both.
Here's the function, with associated code:
function validate_check(input, message)
{
var par = input.parentNode;
var prev = input.previousSibling;
if(!input.checked) {
if(prev.innerHTML != message) {
var errmsg = document.createElement("p");
errmsg.innerHTML = message;
par.insertBefore(errmsg, input);
}
dosubmit = false;
} else if(prev.innerHTML == message) {
par.removeChild(prev);
}}
var agree = document.getElementById('agree');
var agreemsg = 'Please make sure you agree to our <a href="/tou.php" target="_blank">Terms of Use</a> and <a href="/privacy.php" target="_blank">Privacy Policy</a> to add your listing.'
validate_check(agree, agreemsg);
For the two attributes the function accepts, input is a node from that document tree that is a checkbox, and message is a string.
If the checkbox is not checked the function inserts a <p> element immediately before the input. That part works fine in both. However, the 'prev.innerHTML == message' and 'prev.innerHTML != message' don't work properly in IE. I think it is because of the <a> tags in 'message'. However, when I try to use the String() function there are problems because the 'prev' object is not always set, (like, if a paragraph isn't written right before the checkbox).
I can not for the life of me get an ajax example/tutorial to work. I have tried dozens including prototype library and JQuery.
Here is my latest attempt:
As you can see I am trying to alert the variable teamH but I keep getting an undefined in the alert. I also tried a static drop down and I received the same undefined alert.
How I get that variable to contain my drop down choice?
I have an an element that can successfully be retrieved by document.getElementById('id'),but when I attempt to alert(document.getElementById('id').innerHTML), the string is empty. Then, if I try to change the innerHTML like this:
document.getElementById('id').innerHTML += "new string", I get "unknown runtime error".The thing that bothers me is that the element can be gotten with getElementById, but its property innerHTML seems to be either blank or null when in fact, it contains HTML. By the way, this is all in IE. I have tested in FIrefox, Chrome, Safari, Opera, and it works perfectly in those.
document.getElementById (which + "sel").value = document.getElementById (which + "sel" ).value + "'" + document.getElementById (itemtocheck+i).parentElement.title + "',";
Error: document.getElementById(itemtocheck + i).parentElement is undefined
I'm new to ajax. I've made a script that should return results from database but it keeps telling me just undefined. Code what I have:
Code:
var ajax = null;
function showRes(wut) {
if(wut.length == 0) {
document.getElementById("results").innerHTML = "";
return;
} if(window.XMLHttpRequest) {
// IE7+, ff, chrome, opera, safari
ajax = new XMLHttpRequest();
}else if(window.ActiveXObject) {
// retards
ajax = new ActiveXObject("Microsoft.XMLHTTP");
} else {
alert("Your "browser" does not support AJAX!");
return;
} var url = "search.php?q=" + wut;
url = url + "&sid=" + Math.random();
ajax.open("GET", url, true);
ajax.send(null);
document.getElementById("results").innerHTML = ajax.reponseText;
}
I have a little JS app that is a glorified calculator which I posted the code for below. My code uses the document object to replace the html in the "content" <div> and works great.However, I want to add an inline style in order to change the background of the input (readonly field with an id of "coutput") based on either of the global variables named "MJPD" or "IJPD", (depending on the switch case selected in the user prompt at the beginning of the script.)Simplified....if the value of MJPD is less than 4.6, I want the "coutput" field's background to be red, else be green.The same goes for IJPD, except the threshold for red will be <3.83.Code and what I have tried is below.
<script language="JavaScript">
var MJPD = 1;
var IJPD = 1;

I'm getting this error when trying to simple traversing.

I read that it might have something to do with arrays?
I am having a problem accessing and element by ID in a script that runs via 'window.onload' at the end of all my script definitions. Do the HTML elements exist at that point or should I look somewhere else for a bug?
View 1 Replies View RelatedIs there a way for getElementById to perform a function if it finds an ID that is like something - sort of like a wildcard? I want the function to run if the ID contains "_price". It will have something like 247_price or 23_price. I want to ignore the first number and only concern myself with whether or not it has "_price" in it.
Code:
if (document.getElementById("LIKE_price")) {
//do this
} else {
//do this
}
I've got the following code on one of my pages, it works fine in IE6 and Netscape 6.2, but when you get around to using it on Netscape Navigator 4.08 it doesn't work, instead giving me a "document.getElementByID is not a function" error. Here's the code it has a problem with...
function CrseDets(IDS) {
window.open('coursedetails.asp?whereby=' + document.getElementById(IDS).value,null,'top=0,left=0,width=672,height=500, background="gfx/backgrd.gif", scrollbars=yes');
}
Why this simple script is not working. Trying to use getElementById() but Firebug says the ID is null. I've tried troubleshooting by accessing other ID's but they all come back 'null'. Trying to add 2 classes based on an ID:
<script>
pageId = 1;
if(pageId == 1) {
//alert('This is page' + pageId);
document.getElementById('arta').setAttribute("class", "menu-on menu-a");
}
<./script>
An online example is here: [URL]. I also tried accessing the id like below but got the same result:
document.arta.setAttribute('class', 'menu-on menu-a');
How do I write a javascript function to convert ounces to grams and vise versa using document.getElementById ?

I am trying to pass a variable into document.getElementById and it is returning a null value. I am hoping someone can identify my error and point it out. The frustrating thing is, I got it to work and then changed the code and screwed it up again...ugh. Anyways, here is the HTML side of it (an onclick event in a button, calling a function with these arguments):
Code:
<input type="button"
id="AddHeader"
name="Add Header"
value="Add Header"

FireBug shows the problem is with the first line of the function - it's assigning myDiv null instead of what I want it to assign it (div#myDiv1 I think).

I have a program that calculates change and added a function to determine what currency that should be dispensed based on the change.Right now with my code as is, the calculate change portion works, also if I manually enter a value into the change field it will calculate the currency to be dispursed. My problem is I can't get it to read the value passed to the currency field from the calculate change portion. Here is my code:

I have several divs called 'profile', 'codesamples', 'artportfolio' and 'resume' which are hidden. I also have a visible div called 'bodytext' which is visible. When you click one of the links on my page, the function ClickButton is supposed to run, and send the information contained in one of the hidden divs into my visible 'bodytext' div. Instead, I get 'undefined' when I click one of the buttons.

I have a choice of three market items and I want the value of the selected one to be sent to my form. My code is:[code]I have tried giving them different ids, I have tried replacing the id with checked="id='myitem'", I have tried getElementById('myitem.checked'), I have tried getElementbyName.In my full page I have far more radio buttons, so I don't want to do a getElementById('myitem[0].checked || myitem[1].checked etc.But I have run out of alternatives to try. Needless to say as it currently stands it gives the last radio button's value, which means it doesn't like them having the same id, but when I tried changing how the id was applied, or called - ElementByName, FF gives the error message as id is null.
View 11 Replies View RelatedI'm using JSON/jQuery to pre populate a drop down menu. What I want to do, is once I select a plan from the drop down menu and click submit (go button), to get the details about the plan. The drop down menu get's pre populated, but I don't get anything after clicking go. I check the functions and it seems that in the DoPlanSearch() I get the alerts showing the newly constructed URL that gets me the correct JSON. But not sure what happens once the data is processed after that. I say this, because my alert statement in the DoPlanSearchCompleted(data) gets me NULL data.
I'm just getting started with this, I'm not exactly sure what's the best approach. Also, I'm not sure the way .JSON files is setup here works, it does on my Dev server though.
Code has line: function DoPlanSearchCompleted(data)
It should read function UserPlanSearchCompleted(data). The same problem though exists.
