Javascript function behind checkbox in Gridview

Question

I have Javascript Function that works correctly when the checkbox is checked i.e. sets 'Chk' to true but not when the checkbox is unchecked i.e. also sets 'Chk' to true. The Function then passes two parameters to a second page which runs a Stored Proc (setting a value to true or false). Here is my code:

    <script src="Scripts/jquery-1.4.1.js" type="text/javascript" language="javascript"></script>
<script type="text/javascript">
    function myfunction(invId, Chk) {
    var chkboxValue = ($("#iSelect").is(":checked") ? false : true);
    $.ajax({
        type: "GET",
        url: "upDateMe.aspx?param1=" + invId +"&param2=" + chkboxValue,
        data: "",
        contentType: "text/html",
        dataType: "text"
    });
}

What happens when the checkbox is unchecked? Doesn't work is not enough information :) — Claudio Redi

You can get the checkbox status value by using this

var chkboxValue = ($("#iSelect").prop('checked'));

this will fetch whether it is true or false Your function should like this

function myfunction(invId, Chk) {
    var chkboxValue = ($("#iSelect").prop('checked'));
    $.ajax({
        type: "GET",
        url: "upDateMe.aspx?param1=" + invId +"&param2=" + chkboxValue,
        data: "",
        contentType: "text/html",
        dataType: "text"
    });
}

Here is the fiddle that you want: http://jsfiddle.net/QRNyJ/1/
