Kendo ui网格中分页的Javascript验证

Question

The following code worked as expected, however on the paging click, it still execute and display message "Please select a record first, then press this button". Is there anyway to prevent this unless the export button click. Thank you

$(document).ready(function () {
            $("#Product").on("click",function(){
                var $exportLink = $('#export');
                var href = $exportLink.attr('href');
                var grid = $('#Product').data('kendoGrid');   //get a reference to the grid data 
                var record = grid.dataItem(grid.select()); //get a reference to the currently selected row
                if(record !=null)
                {
                    href = href.replace(/refId=([^&]*)/, 'refId='+record.ID);
                    $exportLink.attr('href', href);
                }
                else
                {
                    alert("Please select a record first, then press this button")
                    return false;
                }

            });

    });

Defining a click handler as $("#Product").on("click",function(){...}) you are actually defining it for any click on #Product not just on you Export button. You should define the on for the button and not for the grid
