How to set the action value in the form form in jquery

From: http://blog.sina.com.cn/s/blog_495e3d130100puqa.html

HTML code:

<form id= "Myformid" name= "MyForm" action= "method=" POST ">
  <input type=" hidden "id=" Inparam "Name=" Inparam "/>
  <input type=" hidden "id=" Tstype "name=" Tstype "/>
  <input type=" hidden "id=" ZD "Name=" Zd "/>
</form>

A friend who is familiar with JavaScript must know that JS can dynamically change the value of the action in the form, as follows:
Document.myForm.action = "userinfo.shtml";
Note that the form tag must have the name attribute, the light has an ID without name does not work

document.myform.attributes["Action"].value = "XXXXXXXX";
document.all ("Myformid"). SetAttribute ("Action", "value of action to be assigned");

Both of these methods are tested in JavaScript.

Here's how to set the value of an action in a form form in jquery.
