jQuery attr in IE7
I have the following HTML:
<a href="myPage.htm">
<img src="anImage.jpg />
</a&开发者_运维技巧gt;
<a href="yourPage.htm">
<img src="anotherImage.jpg />
</a>
<a href="everyonesPage.htm">
<img src="stillAnotherImage.jpg />
</a>
And the following javascript (using jQuery):
$(document).ready(function(){
$('a').live('click', function(e){
e.preventDefault();
alert($('img', this).attr('src'));
});
});
In Firefox this alerts the src attribute of the image clicked, but in IE7 and IE6 it alerts 'undefined'. Any ideas why this is and how to return the src of the image when clicking the relevant anchor tag?
EDIT: Sorry guys, jsFiddle example here (http://jsfiddle.net/wabqw/) with original code (yes, code above was a simplified version). Works in Chrome but no IE (firefox fails to display the images so there's nothing to click on!).
I suspect there might be a problem with your HTML, as you are missing quotes:
<img src="anImage.jpg />
Should be
<img src="anImage.jpg" />
Different browsers may handle this in different ways
For me, in Chorme, it certainly doesn't work in this JSFiddle: http://jsfiddle.net/apKdC/, however when I fix the quotes in this updated fiddle: http://jsfiddle.net/apKdC/1/ it all works fine.
The real problem is that before version 9, Internet Explorer does not recognise unknown elements, such as the HTML5 elements you're using.
You can fix it by including this in your <head>:
<!--[if lt IE 9]>
<script src="//html5shim.googlecode.com/svn/trunk/html5.js"></script>
<![endif]-->
For some background information, read: http://paulirish.com/2011/the-history-of-the-html5-shiv/
Here's a page that does just that, and works in IE6/7: http://jsbin.com/izina3
you don't have correct html syntax see src attribute in first image missing " http://jsfiddle.net/HwmEK/1/ see here its working
I could be totally off-track here but shouldn't you have:
alert($('img', $(this)).attr('src'));
So $(this) not this
