在同一个类别的href前面加上 [英] prepend href with same class

问题描述

我的页面上有以下代码...

I have the following code on the my page...

<a href="javascript:change_product_photo(2);"><img id="alternate_product_photo_2"    style="border-color:#666666;" src="/v/vspfiles/photos/00-6189-2S.jpg" border="1">

有时<a href="javascript:change_product_photo(4);">可能会更多，并且每个索引的索引号都更高，例如5、6、7等.

Sometimes there could be more of the <a href="javascript:change_product_photo(4);"> and each one would have a higher index number 5, 6 ,7, etc.

我想为每个带有javascript:change_product_photo(x)(其中x为索引)的href实例删除change_product_link中的两个"_"，但保留(x)索引

What I want to do is for each and every instance of the href with javascript:change_product_photo(x) (where x is the index) remove both "_" from the change_product_link but leave the (x) index

我的想法是先向包含javascript:change_product_photo的所有href中添加一个类，然后使用该类修改所有href; s，但我对如何执行此操作一无所知.

My thought was to first add a class to all hrefs that contain javascript:change_product_photo and then modify all of the href;s with that class but I am lost on how to do this.

这是我到目前为止所得到的...

Here is what I got so far...

$("a[href*='javascript:change_product_photo']").addClass('link_fix');

现在我不知道如何从网址中删除"_".

Now I don't know how to remove the "_" from the url.

推荐答案

尝试...

$("a[href^='javascript:change_product_photo']")
    .addClass('link_fix')
    .attr('href', function(i,v){
        return v.replace('_','');
    })

根据评论进行编辑，请注意href*=已更改为href^=(从选择器开始)

edit based on comment, note the href*= has changed to href^= (start-with selector)

并从jQuery 1.4开始阅读'Easy Setter Functions'function(i,v){...} . x
