Question

i am using a JavaScript and it have the below code:

<script type="text/javascript">
var count = 0;

jQuery('td').click(function () {
    if ($(this).hasClass('process')) {
       count = count+100;
       alert('count');
}
});
</script>

so if its click the value is added by 100 i check using an alert, now how to access the var count in my code-behind

Answer 1

You will need to store the count variable on a server-side control in order to do this.

Example:

<script type="text/javascript">
    var count = 0;

    jQuery('td').click(function () {
        if ($(this).hasClass('process')) {
           count = count + 100;
           alert(count);
           // Store the value in the control
           $('#<%= example.ClientID %>').val(count);
        }
     });
</script>

<asp:HiddenField ID="example" runat="server" />

Then, in your code-behind simply use:

int value;
if (Int32.TryParse(example.Value, out value))
{
     // Do something with your value here
}
