Double "for" loop (loop in loop)

Question

for (var i = 0; i < settings.wrap.find('.tt_selectedRow').length; i++) {

    for (var k = 0; k < settings.columnName.length; k++) {

        var tt_obj = {
        settings.columnName[k]: 
        $(settings.wrap.find('.tt_selectedRow [data-tt_column=' + settings.columnName[k] + ']')[i]).text(), };
    }
    tt_data.push(tt_obj);
}

I need to do the k loop to obtain name of data-tt_column and them the i loop to obtain number of array preaviously created

What's wrong? when i start function = Unexpected token . on first settings.columnName[k]

What is `settings.wrap`? There is not enough of your code here. — dgo, May 18 '16 at 14:43
`settings.columnName[k]` is not a valid object literal, you're taking the wrong approach to fill the object (Which can easily be fixed by firstly declaring an empty object and, **then**, by filling it). Besides, what is `settings.wrap`? I would most care about that at such a point and, then, we may move on by fixing the object (check this for reference, it's quite important to actually know (almost) everything about javascript objects: http://stackoverflow.com/questions/11508463/javascript-set-object-key-by-variable) — briosheje, May 18 '16 at 14:45

You have a wrong field name definition. This one will be right :

for (var i = 0; i < settings.wrap.find('.tt_selectedRow').length; i++) {

    for (var k = 0; k < settings.columnName.length; k++) {

        var tt_obj = {};
        tt_obj[settings.columnName[k]] = $(settings.wrap.find('.tt_selectedRow [data-tt_column=' + settings.columnName[k] + ']')[i]).text();
    }
    tt_data.push(tt_obj);
}
