Can't Get GetElementsByClassName To Work In A Simple Example?
Apr 17, 2011
I can't get GetElementsByClassName to work.Clicking on the first button moves data to a second function that when clicked moves the data to the input field.This codes works when I change getElementsByName('pics')to getElementById('upload').But I need it to work with getElementsByName().
Code:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>[code]....

I can't get getElementsByClassName to work in Internet Explorer.What I want to do is open external links in a new window without using the target attribute (because the site is XHTML Strict) nor inline Javascript.I've given the external links the class name "external":
Code:
<a href="http://webdeveloper.com/" class="external">...</a>
I then wrote the following function, which works in all browsers (Mozilla Firefox, Opera, Google Chrome, Safari) except Internet Explorer:
Code:
window.onload = function() {
external=document.getElementsByClassName('external');
for (var i=0;i<external.length;i++) external[i].onclick=function() {
[code]....
How can I get this to work in Internet Explorer too?Or which other function can do what I want in Internet Explorer?

The following script works fine in IE6. In FF 1.0.7, it doesn't display the response text. The alert()'s in the script show that:
1) the script successfully creates the request object
2) 'http_request.status' starts off equal to 0
3) the readystate displays: 1, 1, 2, 4
4) an error occurs when the script tries to access the .status property of the request object after the request has been sent and the readyState reaches 4(line marked in red below).
<html>
<head><title></title>
<script type="text/javascript" language="javascript">
function makeRequest(url)
{
var http_request = false;
if (window.XMLHttpRequest)
{ // Mozilla, Safari,...
http_request = new XMLHttpRequest();
alert(http_request); //object XMLHttpRequest
alert("status: " + http_request.status); //status: 0
/*
alert("overriding mime type");
http_request.overrideMimeType('text/xml');
*/
}
else if (window.ActiveXObject)
{ // IE
try
{
http_request = new ActiveXObject("Msxml2.XMLHTTP");
}
catch (e)
{
try
{
http_request = new ActiveXObject("Microsoft.XMLHTTP");
}
catch (e) {}
}
}
if (!http_request)
{
alert('Giving up :( Cannot create an XMLHTTP instance');
return false;
}
http_request.onreadystatechange = function() { alertContents(http_request); };
http_request.open('GET', url, true);
http_request.send(null);
}
function alertContents(http_request)
{
alert(http_request.readyState);
if (http_request.readyState == 4)
{
ERROR ---> if(http_request.status) alert("status property exists");
else alert("no status property");
if (http_request.status == "200")
{
alert(http_request.responseText);
}

}
}
}
</script>

I'm having some trouble trying to get a simple GET to work.
I have a page called 1.php with the following code:
This all works fine when I link directly to the page (I.e [url]), however when I load this page through jquery (so the url becomes [url]) the GET functionality stops working.

I've tried to address this issue multiple times, and yet IE 8 simply ignores it. I know jquery has the capability of operating correctly with other examples, but the below code just doesn't seem to satisfy it.[code]

i can't seem to get the getElementsByClassName function to work on IE. I don't know why.
There is no error on IE. I've tried with IE Tester and i get this error:
Object doesn't support this property or method
Additional Note: This works on Firefox and Chrome
Code JavaScript:
function getElementsByClassName(className) {// Get a list of all elements in the document
// For IE
if (document.all) {
[Code]......

I'm trying to implement getElementsByClass() for the document object
and the Element interface, that supposed to work for HTML, XHTML, SVG
and MathML class attributes (including mixed namespace documents) and I
have it working perfectly in Gecko (tested in Firefox 1.0.6 and Deer
Park Alpha 2). I'm just having some serious problems with IE and a bug
in Opera.
The test [1] is supposed to get a NodeList (an Array() with an item()
method added) of elements by class name and then output an alert()
containing the tagNames of the selected elements.
After a fair bit of testing, I believe the problem is occuring with the
way I'm trying to attach the getElementsByClassName() and hasClassName()
functions to elements in IE using an HTC. It seems to be breaking at
the point within document.getElementsByClassName() where I call
element.hasClassName (line 34 of the script [2]) but my understanding of
this workaround using HTCs [3]] that I'm trying to use is very limited
and I don't understand why it's breaking. Code:

im on a really tight deadline with this and have been strugglign all day. (i know nothing about JS!) here's my code:
<script language="Javascript">
var allHTMLTags = new Array();
function fadeIn(SRC) {
var allHTMLTags=document.getElementsByTagName("*");
for (i=0; i<allHTMLTags.length; i++) {
if (allHTMLTags[i].className.indexOf(",") !== -1)
[Code]...
the end result needs to go through and find all divs with a class CONTAINING the term specified in the <li> then give them an opacity of 1, then on mouseOut return the opacity to 0.5

The "Permission denied" cross site issue.
I have to check from my external domain if a service is running on localhost:8080 of a local machine.
I'm using XMLHttpRequest to do it.
I'm checking a local-web-server, not a file.
Every browser doesn't work, but Firefox. So I'm looking for a work-aorund.
An iframe? a flash swf? an applet java? HTA applications?
A side question is, why does FF work? Because it's a local-web-server?

I have a form1 with two fields, field1 and field2. I want the contents of field1 to be transferred to field2 onBlur, but with some changes. I want the contents of field1 to have its spaces replaced with Dashes, and all punctuation removed, so this can happen:
FIELD 1 value:
Today's rate is 15%, & the outlook is good.
onBlur should then create a value of:
FIELD 2 value:
todays-rate-is-15-percent-and-the-outlook-is-good
Notice that the "&" was converted to "and", the "%" to "percent". The comma
was deleted and all spaces replaced with Dashes. The second field should
only every contain alphabetic letter, dashes, and numbers.
