将当前网址作为变量传递给jquery [英] Pass current url as variable to jquery

问题描述

很抱歉，如果这已经得到解答，但我找不到它。

我试图选择与当前网址的链接，因为它是链接的href，并展开它的父母。

Html：

 < ul class ='product-categories'> 
< li>< a href ='http：//example.com/link1'>链接1< / a> 
< ul> 
< li>< a href ='http：//example.com/link/sub-link1'>子链接1< / a>< / li> 
< li>< a href ='http：//example.com/link/sub-link2'> Sub link 2< / a>< / li> 
< li>< a href ='http：//example.com/link/sub-link3'>子链接3< / a>< / li> 
< / ul> 
< / li> 
< li>< a href ='http：//example.com/link2'> Link 2< / a>< / li> 
< li>< a href ='http：//example.com/link3'> Link 3< / a>< / li> 
< li>< a href ='http：//example.com/link4'> Link 4< / a>< / li> 
< / ul> 
  

Jquery：

  var url = document.URL; 
 $（'a [href = url]'）。parentsUntil（'ul.product_categories'）。slideToggle（'fast'）; 
  

由于某些原因，如果我将url直接粘贴到函数中，但不起作用一个变量？我尝试使用window.location.href而不是，相同的结果。也提醒了网址的内容，这很好。

连接到函数中具有相同的结果。

无效：

  $（'a [href ='+ url +]'）。parentsUntil（'ul.product_categories'）。slideToggle（'fast'）; 
  

如果我将url直接粘贴到函数中，它可以工作

  $（'a [href =http://example.com/product-category/bamboo-cutting-board/round-cutting-board/]' ）.parentsUntil（ 'ul.product_categories'）的slideToggle（ '快'）。 
  

解决方案

字符串连接：

  $（'a [href =''+ url +''''）
  

Sorry if this has already been answered, but I couldn't find it.

I'm trying to select the link with the current url as it's href in a ul of links, and expand it's parents.

Html:

<ul class ='product-categories'>
     <li><a href ='http://example.com/link1'>Link 1</a>
           <ul>
                 <li><a href ='http://example.com/link/sub-link1'>Sub link 1</a></li>
                 <li><a href ='http://example.com/link/sub-link2'>Sub link 2</a></li>
                 <li><a href ='http://example.com/link/sub-link3'>Sub link 3</a></li>
           </ul>
     </li>
     <li><a href ='http://example.com/link2'>Link 2</a></li>
     <li><a href ='http://example.com/link3'>Link 3</a></li>
     <li><a href ='http://example.com/link4'>Link 4</a></li>
</ul>

Jquery:

var url = document.URL;
$('a[ href = url ]').parentsUntil('ul.product_categories').slideToggle('fast');

For some reason this works if I paste the url directly into the function, but doesn't work with a variable? I've tried using window.location.href instead, same result. Have also alerted the contents of url, which was fine.

Concatenating it into the function has the same result.

Doesn't work:

$('a[href= " + url + "]').parentsUntil('ul.product_categories').slideToggle('fast');

If I paste the url directly into the function, it works

$('a[href= "http://example.com/product-category/bamboo-cutting-board/round-cutting-board/"]').parentsUntil('ul.product_categories').slideToggle('fast');

解决方案

String concatenation:

$('a[href="' + url + '"]')
