Filtering table multiple columns

Question

I used w3School code for my page and it works fine but it only filters one column, don’t know how create loops but hopping there is easier solution.

    td =         


        

Answer 1

function filterTable(event) {
    var filter = event.target.value.toUpperCase();
    var rows = document.querySelector("#myTable tbody").rows;
    
    for (var i = 0; i < rows.length; i++) {
        var firstCol = rows[i].cells[0].textContent.toUpperCase();
        var secondCol = rows[i].cells[1].textContent.toUpperCase();
        if (firstCol.indexOf(filter) > -1 || secondCol.indexOf(filter) > -1) {
            rows[i].style.display = "";
        } else {
            rows[i].style.display = "none";
        }      
    }
}

document.querySelector('#myInput').addEventListener('keyup', filterTable, false);
