Get Records by Generic Handler Using JQuery in Asp.net

HandlerUse.aspx——————————————————

<div>
<div>
Search User
</div>
<div>
User ID<asp:TextBox ID=”txtID” runat=”server” MaxLength=”1″></asp:TextBox><asp:Button
ID=”btnSearch” runat=”server” Text=”Search” />
</div>
<span id=”msgresult”>Loading.</span>
<div>
<table>
<tr>
<td>
Id
</td>
<td>
Name
</td>
<td>
Price
</td>
</tr>
<tr>
<td id=”IdRes”>
</td>
<td id=”NameRes”>
</td>
<td id=”PriceRes”>
</td>
</tr>
</table>
</div>
</div>

Add below Section to Head

<script src=”jquery-1.7.2.min.js” type=”text/javascript”></script>
<script type=”text/javascript”>

$(document).ready(function () {
$(“#msgresult”).hide();

//Button Click Event
$(“input[id$=btnSearch]”).click(function () {
var id = $(“input[id$=txtID]”).val();
var myTimer = setInterval(Inprocess, 1000);
//Giving value from handler using post method
$.post(“Handler.ashx”, { id: id }, function (result) {
var res = result;
var splitRes = res.split(‘||’);
$(“#msgresult”).show();
$(“.Result”).attr(‘style’, ‘display:block’);
$(“#IdRes”).html(splitRes[0]);
$(“#NameRes”).html(splitRes[1]);
$(“#PriceRes”).html(splitRes[2]);
$(“#msgresult”).html(“Records.”);
$(“#msgresult”).css(“color”, “green”);
clearInterval(myTimer);

});
return false;
});

//Function for Loader like Loading……
function Inprocess() {
$(“#msgresult”).show();
$(“#msgresult”).html($(“#msgresult”).html() + “.”);
}
});

</script>
<style type=”text/css”>
.Result
{
display:none;
}
</style>
