Question

I am using this function:

function sel_test(e) {
  //alert(e.length-1);

  var splitdata = e.split("d");
  var newstr = e.substring(0,e.length-1);

  dropcall = 1;
  nodes = newstr.split(';');
  o = 0;
  if (nodes[0] == '1') o = nodes.shift();
  for (i=0;i<nodes.length;i++) {
    e = nodes[i];
    var ul = document.getElementById(e);
    if (icons) var img = document.getElementById(e+'i');
    if (ul) {
      if (((ul == 'none') AND (ul.style.display == 'none')) OR (ul.style.display == '')) {
        ul.style.display = 'block';
      } else if (!o) {
        ul.style.display = 'none';
      }
    }
  }

javascript is giving me an error of missing parenthesis:

if (((ul == 'none') AND (ul.style.display == 'none')) OR (ul.style.display == '')) {

what this the correct way of doing this.

Answer 1

You should be using && and || instead of AND and OR.

Shouldn’t you?
