Why Doesn't Document.getElementById Find My Control
Jul 20, 2011
[url]
@ page.load the init() function on this page will find everything just fine. However if I call init() after the load it does not find the referenced controls. My goal is to set the imageurl in the hidden "imageurl" textbox, then call init from the treeview to reload the image. Not rocket science, IF I could get it to find the controls.
What I don't get is the results from the "get objects" text box I put at the top. If I look though all the elements on the page, shouldn't I see a heck of a lot more than this?

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'm having a problem with some dynamically loaded content.
1. Ajax request returns some content that goes in a div. Inside that content, there's a text box with the id "coupon"
2. Also inside that content is a script called add_coupon that sends another ajax request. Use pushes a button, function gets called, all is well.
3. Inside the function, "document.getElementById ( 'coupon' )" returns undefined.
Behold:
<script language='javascript'>
function add_coupon() {
document.getElementById('cart_cc').innerHTML = "<img src='spinner.gif'>";
var coupon = document.getElementById('coupon');
if ( !coupon )
alert ( 'no coupon box' );
$(function() {
$.ajax({
type: 'POST',
url: '/store/ajax_add_coupon/'+$('#coupon').val(),
success: function(data) { $('#cart_cc').html(data); }
});
});
}
</script>
<span style='float: left;'>Coupon: <input type='text' id='coupon' size=15/> <input type='button' value='Add' onclick='add_coupon();' class='btnGreenCSS'/></span>

I have some web-server-side code that may place a textbox anywhere on a
page. It might be on the page itself, it might be within a <form>, it
might be within a <div> in the form, or in a <div> inside the first
<div>.
Is there a script out there that will let me, given just the control's
ID, recursively find it anywhere on the page so I can set focus to it?

I am having a bit of trouble with running my own (onkeyup) code in
response to a tab and then making sure that the tab-effect still occurs
i.e. focus on the next control in the tab order isn't happening even
though I return true from the function.

I need to find what control is in some position given.
I mean, if I give the values left: 200px and top 300px I need to know
what control in the page is in that position, or if there is not any.

I have an onchange method for a select box that goes something like
this (the select is in a form named aForm):
function page_on_change() {
pageElement = aForm.my_page_id;
aForm.nav_page_name.value =
pages[pageElement.options[ pageElement.selectedIndex ].value];
var si = pageElement.selectedIndex;
for ( i = 0 ; i < pages.size ; i++ ) {
document.getElementById("id_" + i).style.display='none'
}
document.getElementbyId("id_" + si).style.display='none'
}
IE fails on the statement:
document.getElementbyId("id_" + si).style.display='none'
and says it doesn't support this property.
What is the workaround?

Basically i'm trying to draw a box over an image which
is turning out to be a nightmare. The problem i'm getting at the moment
is that i'm creating a line with <div which works when it's not hidden
but I need to be able to make it hidden so I can use layers to show all
when it finished drawing to make it smoother. This is how some other
scripts are doing it that i've seen. So i've got it drawing a line and I
need getElementById to pick out the layer but it's only picking out NULL
with the one i've got enabled below. I've tried the others but they just
come out as errors. I need to get top2 which is the <div line to show
itself but I can't seem to reference it by getElementById. I use linux
mozilla so i need it working in mozilla as well as windows that's why
i'm using getElementById. My code is below any ideas anyone?

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');
}

First a little background. I have a client (in-house) who insists that our training pages (launched from within iframes on a parent page) be able to load .wmv files with variables for the width and height parameters so we don't have to recode when videos are switched. Flash videos are not an option.
I've searched the net and have received several suggestions and even code snippets from several sources but the only one that comes close to working is this one:

I'm a perplexed nube, and I can't understand how document.getElementById evaluates to true when no parameter is passed to getElementById. This code alerts 'foo' if (document.getElementById) {alert('foo')} else {alert('bar')}
Just to double check, this code alerts 'bar'
if (!document.getElementById) {alert('foo')} else {alert('bar')}

When using instead of this line (to change style of element)
document.getElementById('ImgId'').style.visibility = "visible";
one would use (to change class of element)
Does className change the class="imgHidden" into "makeImgVisible" here?
document.getElementById('ImgId').className = "makeImgVisible";
.imgHidden {visibility:hidden;}
.makeImgVisible {visibility:visible;}
<img src="myImg.jpg" alt="" id="ImgId" class="imgHidden" width="200" height="200">
