How to read rows if repeater control in javascript

Here is the code may be helpful to you:

In repeater or any asp.net data control generates id as controlId+(_rowsNo) so that you can find all the controls row by row using javascript as below.

var repeaterControl = document.getElementById("dvRepeater");

    var tableControl = repeaterControl.getElementsByTagName("TABLE");

    for (var i = 0; i < tableControl.length; i++) {

        var correctAnswer = document.getElementById("ContentPlaceHolder1_rptID_txtCorrectAnswer_" + i).value;

        if (correctAnswer == "") {

            status = false;

            document.getElementById("ContentPlaceHolder1_rptID_txtCorrectAnswer_" + i).style.borderColor = "red";

        }

}
