Question

I have javascript function return array like this:

 <script type="text/javascript">
        function looping() {
            var column_num = 1;
            var array = [];
            $("#columns ul").not("#column1").each(function() {

                var ulId = $(this).attr("id");
                var ulClass = $(this).attr("class");

                if (ulId != undefined && ulClass != undefined) {
                    var order = -1;
                    column_num++;
                    $("li", $(this)).each(function() {

                        var liId = $(this).attr("id");
                        var liClass = $(this).attr("class");
                        if (liId != undefined && liClass != undefined) {
                            order++;

                            var result = liId + "|" + liClass + "|" + column_num + "|" + order;

                            array.push(result);

                            //alert(array[0]);

                        }
                    });
                }
            });
            return array;
        }

    </script>

How can I retrieve the result in another array in my code behind .cs in button click event?

Answer 1

Store the array in a hidden field <input type="hidden" name="hidfld" id="hidfld" /> inside your form.

document.getElementById("hidfld").value = array;

On the serverside, use the hidden field’s name to retrieve the array
