% in ajax url issue

% in ajax url issue

I use jQuery.ajax POST to post data to my MS SQL Server using ColdFusion Web server.
When user has % in the data then it wipe out all text field, if user content does not have % sign then it go through to server and add or modify the data.

Is it possible the web server encode % for some server code for this issue?

Your help and information is great appreciated,

Here is my sample code,

 jQuery("#Submit").click(function(event) {

     event.preventDefault();
      jQuery.ajax({
              url:
              "Myserver.cfc?method=MyMethod&MyData="
         jQuery("#txtMyData").val()
   type: "POST",
              success: function(data)
              {
                  alert( "Data update completed");
                
              }
            }
         
        });
