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 RepliesI 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 have some initialization to be done at page load time, which changes
the text of some anchors so that they are consistent with the query
string (these anchors are used as criteria selectors, and should be
initialized to the criteria contained within the url).
IE and Safari fire the onload event before rendering any elements, so
when the event handler synchronizes the anchors, they are rendered with
the right contents immediately. Firefox, though, renders the page
first, and then fires the handler, which results in the anchors getting
their initial values, and then changing to proper selections. I've
tried calling my init() method immediately after the anchors are
defined in my document - no difference, looks like Firefox is rendering
everything as soon as it's encountered in the document.
Is there any way to have my code run before any elements are rendered
in Firefox? Currently I've "solved" this by hiding the containing div
in the document, and showing it after making changes. This results in
the UI visually reloading itself with each new page, which is not very
desirable either.
How you handle back button scenario in firefox browser. The problem is when i click browser back button , the javascript on load is not executed and page is rendered from cache.
View 1 Replies View RelatedI have no idea why this would function correctly under every browser but IE8. I'm using the $.get function to execute a php script onload.
Here's the code
The script itself is a simple mysql update query and given that this issue only effect one browser, it's clearly a issue on the client side.
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:

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
View 2 Replies View RelatedI 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.
I want to restrict getElementById to search children of a specific element instead of searching the entire document, in the same way that I can do getElementsByTagName using a specific element as the parent.
In this particular instance the parent is a table and the elements I'm interested in are all TDs, so I did the basic getElementsByTagName('TD') off the table and looped through this array checking the IDs. However, I'm suspecting that the browser can do getElementById faster than I can do a loop in javascript. Is there a neater way to do this? For now, I'll settle for IE-only solutions, though it would be nice to have things work in generic browsers.
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 have the following problem in Internet Explorer 6: after loading Google map (use simplest example from Google API site) I see abracadabra instead of russian letters on control buttons ("Satellite" and others).
If I simply remove check from View | Encoding Auto-Select and then check this item again the page is refreshed and everything is ok with russian letters. (By the way, there is no such problem in FireFox).
So my question: is it possible to execute these menu commands by the Javascript code? If yes - how? If no - what to do?
i want run a script where if a user closes browser window then it should execute some set of codes.

Can anyone shed some light on the JavaScript support on many of the
most common mobile browsers (the newest versions of Blazer, Blackberry
and Pocket IE)? Specifically, I am trying to render some content using
innerHTML when the page loads without success. document.write is
supported but does not meet my needs.
as you can tell by the following statements, i'm new to jQueryI'm trying to do the following (in plain english) without too much success.. ) when document ready.. 2) find the element with id 'next'.3) pull / take all 'li' elements, and perform so and so, all whilst excluding 'last' element.
$(document).ready(function() {
$('#next').click(function() {
$('li').each(function() { //for each li ..

I keep getting an error stating "getElementById("ballElement") is null, but I have a div with that exact id. I have looked at the JS script before that line, but found no errors there either. Please take a minute to see if you find something.

I create an xml file in a text editor:
<?xml version="1.0" encoding="utf-8"?>
<elts>
<elt id="1" class="c1">content1</elt>
<elt id="2" class="c1">content2</elt>
</elts>
Then I load the file via xmlHttpRequest into xmlData variable.
Why does xmlData.getElementById(Ƈ') return null and
xmlData.firstChild.childNodes[0].className returns null also?
I have prepared this jsfiddle test [URL] which works in Firefox but not in Chrome.
View 3 Replies View RelatedI am trying to use the script for a PHP integrated website whereby, I am having HEADER and FOOTER for all pages. But the problem is I am already having two other Javascripts in the HEADER so, somehow I am having problem getting the script to work. When I tried to get all the three javascripts to work, the JS menu buttons refused to load properly. Below you will find how both IE and Netscape react towards the script.
Could somebody help me solve this conflict. This seems to be onLoad function handler problem but I don't know how to go about it. Or browser compatibility problem.
Something very interesting is happening and I don't know how to go about it. Below script shows the the two different reaction of both IE and Netscape.
Both IE and Netscape used to load successfull without the Random Table Backgroung Image Rotater. This problem startd when I added the Random Table BG Image Rotater that's why I am including this script also.....
Does anybody know what's happening here? It's driving me nuts.
<a id="prevLink" href="#" alt="prev">previous</a>
getElementbyId("prevLink") returns the href value, but I need to work with the A element itself.
I want to use the document.getElementByID method to change the text of an element.
It works and replaces the old text but the new text is lower down when I want the new text to be on the same line.

I'm trying to get a value from a database, assign it to an innerHTML value of a certain element and display this on a web page. Here is how I do this. First I have a js function. Very simple one, here it is:
function get_page_contents(page_name)
{$.post("includes/ajax.php?mode=get_page", {pagename: page_name}, function(data)
{
$('#hed1').html(data.h1);
$('#content').html(data.content);
[Code]...
This javascript function is being invoked upon clicking on a link. The point is that the content's innerHTML is displayed beautiful while I cannot see H1 innerHTML. Its value is NULL instead of expected database value.
I have a <div> tag that is getting updated by calling a php script. Inside of the div's innerHTML, there is a <select> tag.I need to be able to change the div whenever a user changes the select tag. How can I do thisI've been trying to get the select tag, but it doesn't seem to evaluate right.
