Question

I want to display result of this javascript in a label control on my asp.net page, instead of alert. how can i do so?

<script type="text/javascript" language="Javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script> <!-- Require EasyJQuery After JQuery --><script type="text/javascript" language="Javascript" src="http://api.easyjquery.com/easyjquery.js"></script> <script type="text/javascript" language="Javascript">
    // 1. Your Data Here
    function my_callback(json) {
        alert("IP :" + json.IP + " COUNTRY: " + json.COUNTRY);
    }

    function my_callback2(json) {

       alert("IP :" + json.IP + " COUNTRY: " + json.COUNTRY + " City: " + json.cityName + " Region Name: " + json.regionName);
    }

    // 2. Setup Callback Function
   // EasyjQuery_Get_IP("my_callback"); // fastest version
    EasyjQuery_Get_IP("my_callback2","full"); // full version
</script>

Using Dynamic ID

The label control of asp.net is rendered by default as span So you can set the text inside by find this control by ID, and type inside using the text as:

  $('#<%=txtLabel.ClientID%>').text("message");

Using Static ID

alternative (ver 4+) you can set ClientIDMode="Static" on your control so the id not change

<asp:Label runat="server" ID="txtName" ClientIDMode="Static">Test</asp:Label>

render as <span id="txtName">Test</span> and write inside him as

$('#txtName').text("message");

Your function will then be

function my_callback(json) {
    $('#txtName').text("IP :" + json.IP + " COUNTRY: " + json.COUNTRY);
}

function my_callback2(json) {
   $('#txtName').text("IP :" + json.IP + " COUNTRY: " + json.COUNTRY + " City: " + json.cityName + " Region Name: " + json.regionName);
}
