jQuery选择器 [英] jQuery Selectors

问题描述

我想从视图源中获取这个，例如：

 < a href =javascript：validateCB ;>< img src =wwv_flow_file_mgr.get_file？p_security_group_id = 1343380920146312332& p_flow_id = 222& p_fname = submit_btn.gifalt =Submit Detailsborder =0/> 
  

转换为jQuery选择器格式

  var $ templateButtons = $（'img [src ^ =wwv_flow_file_mgr]'）。parent（'a'）; 
  

但这似乎不正确。

任何想法如何将上述视图源代码翻译成jQuery？

谢谢，
Tony。

$（'img [src ^ =wwv_flow_file_mgr]'）

您遇到了已知错误在jQuery v1.3.2 - jQuery试图解释图像路径使用其绝对URL，这意味着它比较的URL实际上以 http：// ...

您可以使用 * = （它查找包含文本 wwv_flow_file_mgr，而不是以它开头）：

  var $ templateButtons = $（'img [src * =wwv_flow_file_mgr]' ）.parent（'a'）; 
  

I am trying to take this from view source, i.e.:

<a  href="javascript:validateCB();"><img src="wwv_flow_file_mgr.get_file?p_security_group_id=1343380920146312332&p_flow_id=222&p_fname=submit_btn.gif" alt="Submit Details" border="0"  />

into jQuery selector format

var $templateButtons = $('img[src^="wwv_flow_file_mgr"]').parent('a');

But this doesn't seem to be correct.

Any ideas how to translate the above view source code into jQuery?

Thanks, Tony.

解决方案

The problem is with the attribute selector: $('img[src^="wwv_flow_file_mgr"]')

You're experiencing a known bug in jQuery v1.3.2 - jQuery is trying to interpret the image path using its absolute URL, which means the URL it's comparing actually starts with "http://..."

You can temporarily get around this using *= (which looks for an attribute value that contains the text "wwv_flow_file_mgr" instead of starting with it):

var $templateButtons = $('img[src*="wwv_flow_file_mgr"]').parent('a');
