Patricia_C

Hi
I been working on a feature which the titles has to be dynamic created . The titles depends what data return from the server. I tried to set the data for aoColumns in dataSrc funtion ,but i kept running into aDataSort of undefined. Couldn't even debugger in the function.

Is any way that i can dynamic the titles?

data from server side
data:[{
couponName:'CType1',
couponPrice:'1000',
paymentId:'111111-111111-111111',
SignupUserInfoList:[
{ columnName:'Name',columnValue:'Peter'},
{ columnName:'Number',columnValue:'0978123456'},
{ columnName:'Email',columnValue:'Peter123@gmail.com'}],
}]

reset data in dataSrc function
columns=[
{ sTitle:'Name',mData:'Peter'},
{ sTitle:'Number',mData:'0978123456'},
{ sTitle:'Email',mData:'Peter123@gmail.com'}],
]

<table id="displayTable" class="table table-bordered table-hover" width="100%"></table>

 $('displayTable').dataTable({
        "language": cn_dataTable,
        "destroy": true,
        "autoWidth": true,
        "searching": false,
        "serverSide": true,

            "dataSrc": function (json) {
                if (json.data.length > 0) {
                    var cValue = '';
                    for (var x = 0; x < json.data.length; x++) {
                        if (json.data[x].SignupUserInfoList.length > 0) {
                            var sLength = json.data[x].SignupUserInfoList.length;
                            for (var y = 0; y < sLength; y++) {
                                var title = json.data[x].SignupUserInfoList[y].columnName;
                                var value = json.data[x].SignupUserInfoList[y].columnValue;                                                          
                                column = { "sTitle": title , "mData": title},
                                columns.push(column);
                                columnDatas.push(value);
                            }
                            dataSet.push(columnDatas);
                        }
                    }
                }
                return columnDatas;
            },
