JS get information about the row where the button is clicked

Use JS to get the button in a cell in the table to get the information about the row:

The code copy is as follows:

function GetRowNo() {

var e = e || window.event;

var target = e.target || e.srcElement;

if (target.parentNode.tagName.toLowerCase() == "td") {

rowIndex = target.parentNode.parentNode.rowIndex;

}

}
