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

I uploaded the code here to search table data among two columns

function searching() {
    var input, filter, table, tr, td1, td2, i, txtValue;
    input = document.getElementById("search");
    filter = input.value.toUpperCase();
    table = document.getElementById("table");
    tr = table.getElementsByTagName("tr");

    for (i = 0; i < tr.length; i++) { 
        td1 = tr[i].getElementsByTagName("td")[0];
        td2 = tr[i].getElementsByTagName("td")[1];
        if (td1 || td2) {
            txtValue1 = td1.textContent || td1.innerText;
            txtValue2 = td2.textContent || td2.innerText;
            if (txtValue1.toUpperCase().indexOf(filter) > -1 || (txtValue2.toUpperCase().indexOf(filter) > -1)) {
                tr[i].style.display = "";
            } else {
                tr[i].style.display = "none";
            }
        }
    }
}
