Jqueue values and methods for dynamically setting the Action property of form forms

head> <meta http-equiv= "Content-type" content= "text/html"; Charset=utf-8 "> <title>web Service File up&down test</title> <script type=" Text/javascript "src= "Js/jquery-1.7.js" ></script>  



The JS code above:

1. $ (function ()) function is used to dynamically modify the value of the selected file;

2, GetUrl () method for form submission, modify the value of the action;

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 familiar with JavaScript must know that JS can dynamically change the value of the action in form forms as follows:

Document.myForm.action = "userinfo.shtml";

Note that the form label must have the name attribute, the light has an ID, no name does not work


document.myform.attributes["Action"].value = "XXXXXXXX";

document.all ("Myformid"). setattribute ("Action", "value of the action to be assigned");


Both of these methods have been tested in JavaScript.

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

$ ("#myFormId"). attr ("Action", "userinfo.shtml");

"Note": $ ("#myFormId"). action= "XXX"; This kind of writing is not working!

<form action= "xxx.php" id= "Demo_form" method= "POST" >

<input type= "text" id= "Form_stock" name= "s" data-default= "code/name/Pinyin" value= ""/>

<input type= "hidden" value= "Addstock" name= "action"/>

<button onclick= "$ (' #demo_form '). attr ({' Action ': ' insert.php '}). Submit ();" > Add </button>

<button onclick= "$ (' #demo_form '). attr ({' Action ': ' search.php '}). Submit ();" > Enquiry </button>

</form>

When you use jquery, you can set the following:

Form form:

<form name= "MyForm" id= "MyForm" action= "ssss" "method=" Post "onsubmit=" GetUrl (); " >
 

JavaScript method:

 



<script type= "Text/javascript" >
     function GetUrl () {    
       $ (' form '). attr (' action ', ' New_url ');       
    }
 </script>
 

Or with simple javascript:

 


function Test1 () {  
   alert (document.myform.action);//return value: Http://localhost:8080/XXX/ssss
   alert ( document.myform.attributes["Action"].value)//return value: SSSs    is different from the previous line
//   below three lines,         
   whichever line document.getElementById (' MyForm '). action= ' New_url ';
   document.myform.action= ' New_url ';
   document.myform.attributes["Action"].value = ' new_url ';
}
