jquery - 将data-rowindex值动态存储到数组中

Question

I want to save data-rowindex value dynamically into array

<tr class="ewTableRow" data-rowindex="1" id="r1_assessment_training" data-rowtype="2">

I tried below code. (I am not sure weather below code is correct way or not)?

var a = $('#tbl_assessment_traininggrid tr').length;

var row_count = [];
    for (var i = 1; i <= a; i++) {
        var rowCntrl = $("data-rowindex[i]").val();
        alert(rowCntrl);
        row_count.push(rowCntrl);
    }

Answer 1

The below answer works for me.

$(".ewTableRow").each(function(){
   row_count.push($(this).data('rowindex'));
});

Use Jquery function..!
