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

You just need to add another loop to go over the cells, so:

table = document.getElementById("myTable");
//  tr = table.getElementsByTagName("tr");
// Easier to use the rows collection:
var tr = table.rows;

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

  // Easier to use the cells collection
  // td = tr[i].getElementsByTagName("td")[0];
  cells = row.cells;

  // Loop over all the cells
  for (var j=0, jLen=cells.length; j -1) {
        tr[i].style.display = "";
      } else {
        tr[i].style.display = "none";
      }
    }
  }
}
