Making POST Ajax Calls using DOJO

Here is a simple Dojo based snippet for making an Ajax call to a servlet. This will also display message to the user based on the response received from the servlet.

dojo.xhrPost({
 url: SaveFormValueServlet,
 content: parameters,
 service: this,
 load: function(data){
  alert("success");
  dojo.byId("message").innerHTML=data;
 },
 error: function(errObj,ioArgs) {
  alert("failed");
 }
});
