我们知道普通方式 innerHTML 到容器中的脚本浏览器器是不会执行的,今天看 mootools 的时候发现靠它可以做到.

Ajax 类的说明:

Class: Ajax
    An Ajax class, For all your asynchronous needs.
    Inherits methods, properties, options and events from <xhr>.

Arguments:
    url - the url pointing to the server-side script.
    options - optional, an object containing options.

Options:
    data - you can write parameters here. Can be a querystring, an object or a Form element.
    update - $(element) to insert the response text of the XHR into, upon completion of the request.
    evalScripts - boolean; default is false. Execute scripts in the response text onComplete. When the response is javascript the whole response is evaluated.
    evalResponse - boolean; default is false. Force global evalulation of the whole response, no matter what content-type it is.
   
Events:
    onComplete - function to execute when the ajax request completes.</xhr>

Example:

>var myAjax = new Ajax('js.txt', {method: 'get', update: $$('body'), evalScripts: true}).request();

js.txt:

<script type="text/javascript"> alert('TEST'); </script>
