[Solved] Adding columns dynamically with formatter and styler as string

[Wojak]

Hi,
How could I solve my problem? I tried eval(); and (function() {})();

Code

Code:

function refreshDatagrid() {
    const columns = $('#datalist').datalist('getRows');
    $('#datagrid').datagrid({ columns: [columns] });
}

Data

Code:

[
    {
        "field": "field_fdqzv",
        "title": "title"
    },
    {
        "field": "field_2agdu",
        "title": "2agdu",
        "_selected": true,
        "width": 200,
        "align": "center",
        "formatter": "function (value, row, index) {\n\treturn value + ' ' + index;\n}",
        "styler": ""
    }
]

JSONfn comes with the answer

Code:

$('#datagrid').datagrid({ columns: [JSONfn.parse(JSONfn.stringify(columns))] });
