我想提出一个AJAX调用使用jQuery到需要恢复的javascript code嵌在JSON结果jQuery的code执行PHP脚本。我该如何去通过JavaScript的code以JSON？

I am making an AJAX call with jQuery to a PHP script that needs to return javascript code embedded in a JSON result for the jQuery code to execute. How do I go about passing javascript code in JSON?

推荐答案

有两种方式：

您就必须把它作为一个字符串，并使用的eval（）在客户端上。 您可以使用JSONP，和而不是做一个电话，让您的客户端脚本插入＆LT;脚本＆GT; 及其的src 指向服务器端code，返回新的脚本。 You'll have to pass it as a string and use eval() on the client side. You can use JSONP, and instead of doing a call, have your client side script insert a <script> with its src pointing to the server-side code that returns the new script.

在这两种情况下，一定要保护好它 - 如果用户能以某种方式插入自己的code到你的回应，他们可以做一些损害

In either case, make sure you secure it well - if the user can somehow insert their own code into your response, they could do some damage.
