How to pass a javascript variable value to a jsp value

Question

I have a JavaScript functionality that change the value dynamically on selecting a list box ,i am able to get that value in a text field using the id.But i want to get that value in a jsp variable that i am not able to get this is what i have done ,

          <div class="form-control">
                <label class="lebelMergin" for="_Manager">
                <span class="spanMergin"></span>
             <input type='text' class='text' name='business1' id="hiddenField" /> 
                </label>
            </div>

jquery

$('#branch_branchTypeId').on('change', function (event) {
   //var vl = $("option:selected",this).text();
   var vl = $(this).val();      
   var myvalue=$("option:selected",this).text();
   $('.text').val(myvalue);
   document.getElementById("hiddenField").value=myvalue;

    var target = $("#business");
    if (vl) {
        target.show();
    } else {
        target.hide();

This is showing the value in the div using id.but i want that id in a script variable.

@Thilo thanks for answering but from that question i can not set the value of myvalue in jsp variable — lucifer, Dec 01 '14 at 06:08
You need to send the value to the server somehow. Possibly via Ajax. — Thilo, Dec 01 '14 at 06:09
The Javascript is run *after* the JSP has already *finished*. — Thilo, Dec 01 '14 at 06:12
Why do you need to populate a JSP variable? You can perform dynamic dropdown value change using JS only. Is there any specific reason for setting a JSP variable? — ArinCool, Dec 01 '14 at 06:12

The only ways is AJAX, use AJAX to make call to the server and send all your data along with it, possibly in JSON format.

Use of Jquery's load() will be the best solution which uses parameters and URL which to be called use this link to get more reference

Code snippet:

$.ajaxSetup({ cache: false }); $("#Divsection").load(URLofresourceofAjax,{ "param1OfRequest":value,"Param2":value});
