We have to be a bit familiar with the Java script for the use of ajax. In this example ,a java script function which is calling the post function using ajax. <script type="type/javascript" > function ajaxunload() { //here we created the obj of the xmlhttprequest , which is a mile stone to ajax . // all latest browser like internet explorer 5 or abve uses activeXobject //this object exchanges the data with the server .. obj = new XMLHttpRequest(); //It stores the function or the name of the function to be called automatically when the readystate //property changes obj.onreadystatechange = function () { if (obj.readyState == 4 && obj.status == 200) { // here we are storing the data which is returend from the ajax function. var s = obj.responseText obj.abort(); } } obj.open("POST", "postfunction", true); obj.send(); } </script>
