jqxdropdownlist checkchange事件

Question

我正在尝试使用jqxgrid中的复选框打印jqxgrid下拉列表值我已经绑定了jqxgrid列中jqxdropdownlist中的值但是当我尝试使用checkChange事件绑定vaules时问题是检查值是打印但同时事件多次触发我想一次打印一个值，所以请建议我如何做这个

我试过这段代码

{
    text: 'Sort Type', columntype: 'dropdownlist', datafield: 'aliasname1', width: '11%', editable: true,
    createeditor: function (row, cellvalue, editor, celltext, width, height) {

        // construct the editor.   var requiredfield =
        var requiredfield =
            [
                 "Ascending", "Descending", "Unsorted"
            ];
        editor.jqxDropDownList({
            checkboxes: true, source: requiredfield, autoDropDownHeight: true, selectedIndex: -1
        });

        $(document).on('checkChange', function (event) {

            var checked = event.args.checked;
            var colvalue = $('#shipmentgrid').jqxGrid('getcellvalue', row, 'column');
            var tblvalue = $('#shipmentgrid').jqxGrid('getcellvalue', row, 'table');

            if (checked == true) {

                var textareavalue = $("#txtQueryList").val();
                var sortvalues = textareavalue.split('ORDER BY ');
                var aa = sortvalues[1];


                if (aa != undefined) {

                    var bb = aa.split(',');

                    for (i = 0; i < bb.length; i++) {

                        if (bb[i] != "") {

                            try {
                                var s = bb[i];
                                var t = s;
                                if (colvalue == t) {

                                }
                                else {

                                    var  ee = textareavalue + "," + colvalue;
                                    $('#txtQueryList').empty();
                                    $("#txtQueryList").append(ee);       
                                }

                            }
                            catch (ex) {

                            }
                        }
                    }

                }
                else {
                    $("#txtQueryList").append("\n", "\n", "\n", "ORDER BY", " ", colvalue);
                }     
            }

            else {

            }
        });
    }
}

添加＆＃39; checkChanged＆＃39;编辑器对象的事件处理程序，而不是文档

editor.on('checkChange', function (event) {
