How does dojo/request handle html/javascript response?

Question

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.

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.
