I'm trying to get the value of an object's property. getAttribute returns "null" even though I'm sure the property is set. I can easily set the property, and in my actual script I do so dynamically. I just want to read the property and can't.
To help explain my problem, I've attached an example .html file as a .txt file.
The critical part of the code is this section that is based on "textbook" examples of how to get an attribute:
<script type="text/javascript">
function
showcolor() {
var myobject = document.getElementById("lab");
var myproperty = myobject.getAttribute("color");
alert(myproperty);
}
</script>
This is called via a button on the bottom of the page. The DIV object with the ID "lab" exists and has a color attribute defined in CSS, but I cannot read it, nor any other attribute, with a script. The alert displays "null".
I am trying to get my script working in FF, IE and Opera but the getAttribute isn't working for me. The domain name isn't getting picked up I have tried this:
I am new to this kind of scripting, so I have not done it before, I have tried to find solutions on the net but none have worked.I have a 'contact us' form, which includes 2 radio buttons to select how they wish to recieve their reply... the first radio is 'email' the second radio is 'phone'When the 'phone' radio is selected, i want the div including a drop downbox to appear to ask what time to recieve a call, but when the 'email' radio is selected, this div does not appear.This is the script for this section.
<span>Best way to reply:</span> <input type="radio" name="reply" value="Email" id="reply_0" /> E-mail <BR /> <div style="margin-left:270px;"><input type="radio" name="reply" value="Phone" id="reply_1"
It seems to be a problem with the getAttribute('style') portion of the code because if I change the request to getAttribute('id') it executes properly....
During development of Bing Maps, I've come across a problem when reading in an XML file and plotting a ploygon. The code works fine on IE, but FireFox is giving me the following error message: Error: xNodes[i].getAttribute is not a function
The function in its entirety is copied below and the problem line is marked in red. Hoping that someone may have come across this problem?
I am trying to get a url attribute from an xml node: <item> <media url="http://blablabla.com" /> </item>
I can do this in IE with the following code: var newDom = xmlhttp.responseXML; var x = newDom.getElementsByTagName("item"); var urlNode = x[0].getElementsByTagName('media'); var myUrl = urlNode[0].getAttribute('url');
If I try this code in FireFox it gives me the following error:
urlNode[0] has no properties referring to this line : myUrl = urlNode[0].getAttribute('url');
i have found a possible bug in 1.4 but it's only in Internet Explorer 7 & 8.The following code does not work and completely ruins every peice of jquery on the page (that means everything inside $(document).ready and anyting else...
I cant see any syntax errors - i pulled the example from the 1.4 site. There is no trailing commas in the object notation and i really cant see any reason it would work in firefox and not IEx and more to the point not only not work in IEx but break any other jquery in the entire page....
I'm working with a large (and unweildy) ASP.NET application, and there is a lot of jQuery code that uses selectors like this:
[name=_aspnetControl$_withASubControl] And unfortunately, some selectors that also look like this:
[name^=_someAspNetControl$_radioButtonList].
In other words, the effort to remove the $ from the attribute selectors would be monumental. If it is possible to escape the $ symbols, I can do that easily enough, but unfortunately the situation right now means that I can't upgrade to jQuery 1.5.
I'm learning jQuery with XML. I'm familiar with other query languages such as XPath. I'm having a little bit of difficulty wrapping my brain around how jQuery works but I think I can make the leap if I see a solution to a problem I know how to solve with other methods Given the following XML, please share a jQuery solution to finding the value of attribute B in elements named bar where attribute A has the value 30:
I'll trying to tell the difference between the following three cases:
<img alt="text string" /> <img alt="" /> <img />
I can do this in Firefox with the following code, where elem is the HTMLElement representing each image, but IE doesn't seem to differentiate between empty string and undefined.
var alt = elem.getAttribute('alt'); alt = (alt) ? alt : ((alt===null) ? 'really_null' : "");
The desired output from running this code on the 3 tags above is:
text string
really_null
It seems like this should be really easy...but I'm having a really difficult time trying to figure out what's going on...
I'm working on a slider script and it would be just lovely to be able to specify the slider's width in a width attribute on the input that represents it. In the code below, getAttribute("width") is returning 0 in IE, but seems to work fine in firefox. . . .

I am doing a few tests with javascript and oop. but one failed so i falled back to the way i usually do this but it still isnt working properly. i am using $.post() but instead of returning whatever is echoed in the php file like it does with all my other scripts it returns the content of the file:
Isnt returned in var data but the whole file is returned as a string.

I am aiming to change a couple of items on a CSS definition using JavaScript, so the servicer only needs to update one JS variable. I am so a novice at this...
I would like to be able to set the "top" and "height" attributes of my graphbar ID element after the percent in the JS script is changed.
