Expand|Select|Wrap|Line Numbers

 <div id="editForm">

 <input type="hidden" name="x" value="" >

</div>

the most simple approach (probably) is:

Expand|Select|Wrap|Line Numbers

 function addValue()

{

    this.value = this.name;

}
 
// apply the function

// input being the input element

addValue.call(input);

Hello Dormilich,
I don't see clearly, if the input tag in the div is more than one how will i call the function?

Expand|Select|Wrap|Line Numbers

  
    <script>

     function addValue(status,nameOfForm){

          if(status=="addAll"){

          ......//add x=100 inside nameOfForm div,

         }else {

               ......//add x=-100 inside nameOfForm div

         }

     }

   </script>

<html>

 <body>

  <form name="addForm" onSubmit="addValue('addAll','editForm1')" action="b">

        <div id="editForm1">

     <input type="hidden" name="x" value="" >

      <input type="hidden" name="y" value="" >

       <input type="hidden" name="w" value="" >

    </div>
 
</form>
 
<form name onSubmit="addValue('subAll','editForm2')" name="subForm" action="a">

    <div id="editForm2">

     <input type="hidden" name="x" value="" >

      <input type="hidden" name="y" value="" >

       <input type="hidden" name="w" value="" >

    </div>
 
</form>

</body>

</html>

Thanks and Regards

what do you mean by add x=100? add the string "x=100" to the input’s value? or add 100 to the input’s current value?

unless you have a kind of url rewriting, check the forms’ action attributes, they have to point to a file.
