将$ j替换为JQuery [英] Replace $j with JQuery

问题描述

我有一个有趣的问题.我在Google chrome扩展程序中使用jQuery函数clone().该函数正在克隆表行.问题是TR使用$j()而不是jQuery()在其中包含一些内联javascript/jquery.

I am having an interesting issue. I am using the jQuery function clone() in a google chrome extension. The function is cloning a table row. The problem is that the TR has some inline javascript/jquery in it using $j() instead of jQuery().

每次尝试输出克隆的行时，都会出现错误"$ j未定义".

Every time I try to output the cloned row I get the error "$j is not defined".

因此，我想到了针对此问题的2种可能的解决方案:

So I thought of 2 possible solutions for this issue:

1. 使我的chrome扩展程序与jQuery()的$j()(使用jquery尝试，没有冲突)交互工作

1. Make my chrome extension work with $j() (tried using jquery no conflict) intead of jQuery()

或

1. 在输出克隆项目之前对其进行搜索，将$j替换为jQuery.

1. Do a search in the cloned item before outputting it, replace $j with jQuery.

我的问题是我也无法完成...

My problem is that I cannot accomplish either...

 var rows = jQuery("#field-mapping-template").clone(true);
 rows.insertBefore("#field-mapping-template");

推荐答案

我的意思是，我不建议这样做，但是如果确实需要，可以 .

I mean, I wouldn't really recommend doing this but you can if you really need to.

进入jQuery的开发版本，一直向下滚动到底部，直到看到以下代码行:

Go into the development version of jQuery and scroll all the way down to the bottom until you see this line of code:

// Expose jQuery to the global object
window.jQuery = window.$ = jQuery;

现在只需将其更改为:

// Expose jQuery to the global object
window.jQuery = window.$j = jQuery;

现在，当您编写如下脚本时:

Now when you write a script like:

<input type="hidden" name="name" value="test" />
<script type="text/javascript">
    $j(function () {
        alert($j('input').val());
    });
</script>

代替$，它将适用于$j.

这与替换jQuery()不同. $是jQuery()的简写.

This is different than replacing jQuery(). The $ is short hand for jQuery().

我真的，真的，真的不建议您用$ j或其他任何东西代替jQuery().

I would really, really, really not recommend replacing jQuery() with $j or anything for that matter.

从最新版本(v1.7.2)开始，开发代码中有 879个对jQuery对象的引用，您必须将其更改为$j.

As of the latest release (v1.7.2), there are 879 references to the jQuery object in the development code that you would have to change to $j.

如果您有很好的查找和替换方法，可以这样做，但我不建议这样做.

If you have a good find and replace, you can do it, but I would not recommend doing it.
