如何在数据表中乘以数据？

Question

How do I multiply Data in Datatables ? I have Datatables and javascript that look like this:

$('#xxdata').DataTable( {
        "destroy": true,
        "processing": true,
        "ajax": {
            url  : "xxreport.php",
            type : 'GET',
            data : {
                datedari : SplitRange[0].trim(),
                datesampai : SplitRange[1].trim()
        }
        },
        "columns": [
                { "data": "offerName" },
                { "data": "offerCountry" },
                { "data": "visits" },
                { "data": "conversions" },
                { "data": "profit"}
        ]
} );

I want to multiply data in { "data": "profit"}
maybe like this { "data": "profit" * 0.7}

Can I change data in datatables as I want? Or can anyone give other solutions?

Thank You.

You can use the columns.render option ( documented here ) to do this.

"columns": [
            { "data": "offerName" },
            { "data": "offerCountry" },
            { "data": "visits" },
            { "data": "conversions" },
            { "data": "profit",
              "render": function (data) {
                            return data * 0.7;
                        }
            }
    ]

In this case, data in the function signature represents the data for the cell. There are other options that can be passed into the function, but in your case these do not need to be included since this is such a simple operation. See the documentation link if you ever want to expand to a more complicated rendering function

You must add a render to your column, something like this:

{ "data": "profit", "render": renderMyProfit}

and you should have the rendering function declared before you call the .DataTable() function.

 var renderMyProfit = function (data, type, row, meta) {
            var renderContent = "<div>*</div>";
            return renderContent.replace("*", row.profit * 0.7);
  };
