You can use jQuery Ajax call like this one:- jQuery.ajax({ type: 'POST' , contentType: "application/json; charset=utf-8" , url: 'WebService1.asmx/getCityData' , data: "{'stateName':'" + stateName + "'}" , dataType: 'JSON' , success: function (response) { StateCityChart(response); return false ; }, error: function (er, sw, sq) { //alert("Error occured in application"); } }); 1- In url you need to pass your "pagepath /methodname". 2- If you want to send some data then pass it in data: "" otherwise pass it blank. If you are passing the data then remember to pass it with the name of method otherwise call will not be made.

You can use function showCustomer(str) { var xmlhttp; if (str=="") { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } else {// code for IE6, IE5 xmlhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","getcustomer.aspx?q="+str,true); xmlhttp.send(); }
