how to pass the value from Jquery to jsp?

My jQuery code:

function check_availability(){   

         //get the username   
         alert("hai");
         var result ="";
         var CompanyCode = $('#CompanyCode').val();   
     alert("Jquery " +CompanyCode);
     //use ajax to run the check   
         $.post("checkUserName.jsp", { CompanyCode: CompanyCode },   
             function(result){   
                 //if the result is 1   
                 alert("result"+result);
                 if(result == 1){   
                     //show that the username is available   
                     $('#username_availability_result').html(CompanyCode + ' is Available');   
                 }else{   
                     //show that the username is NOT available   
                     $('#username_availability_result').html(CompanyCode + ' is not Available');   
                 }   
         });   

}

checkUserName.jsp:

String companyCode = request.getParameter("CompanyCode");
out.println("companyCode"+companyCode);


rs = dbAccess.executeQuery("select companycode from yosemitecompany where companycode = '"+companyCode+"'");

How to get the values from jQuery? I need to get the answer in the JSP page for checking ,whether the record is present or not in the table. I am not getting the value from the request.getParamater() method. Is this any other way to check that ?

It seems that CompanyCode is the id attribute.So just create an attribute name="something" then use request.getParameter("something").I hope it will work

Your code is absolutely valid. Only thing as said above the variable naming may the issue. You can try the other option from jquery api,

$.post("checkUserName.jsp", $('#CompanyCode').serialize(),..

This should take care of your issue. Because query string values should be quoted ('') properly. This serialize method would take care of that.

Instead of

     $.post("checkUserName.jsp", { CompanyCode: CompanyCode },

Try

     $.post("checkUserName.jsp", { Code: CompanyCode },

Perhaps it's an issue with naming the keys the same as that var...
