dojo /请求如何处理html / javascript响应？ [英] How does dojo/request handle html/javascript response?

问题描述

实际上，我们知道dojo / request有一个属性handleAs可以处理：

• text


• json


• javascript


• xml

但是如果响应是嵌入JavaScript的HTML片段呢？如何处理？

我有这个问题，而我试图使用句柄：html。

解决方案

正如我在其他问题中解释的那样，JavaScript是<使用AJAX请求（如 dojo / request / xhr ）时，强制>永不自动执行。

如果要执行动态加载的JavaScript代码，则必须使用 eval（）函数来解析它。但是，我也已经告诉过，Dojo工具包已经有一个模块来处理XHR请求，并通过使用 dojox / layout / ContentPane 和 executeScripts property。

然而，使用 eval（）和从AJAX请求中加载脚本被认为是不好的做法，意味着您的应用程序设计可能会得到改进。将JavaScript移动到父页面（代替碎片），然后您没有问题。

Actually, we know dojo/request have a property "handleAs" that can handle about:

• text
• json
• javascript
• xml

But how about if the response is a html fragment with javascript embedded? How to handle it?

I am having this problem quite while, I tried to use handleAs: html. The html rendering fine, but I never get the javascript works.

解决方案

As I explained you in your other questions, JavaScript is never automatically being executed when using AJAX requests (like dojo/request/xhr) out of security matters.

If you want to execute JavaScript code that's dynamically loaded, you will have to use the eval() function to parse it. However, I also told you already that the Dojo toolkit already has a module to handle XHR requests and execute scripts on it by using a dojox/layout/ContentPane and the executeScripts property.

However, the use of eval() and loading scripts from an AJAX request is considered a bad practice and means your application design probably could be improved. Move the JavaScript onto the parent page (in stead of the fragments) and then you have no problems.
