a problem with a simple function

**meee** · Jun 6, 2009, 11:51

I have no idea why the function is not working if I put on the 4th line Example instead of 'test'. So if I put if(document.getElementById('test').value=='') is working, if I put if(document.getElementById(Example).value=='') is not working. It must be some dummy mistake I can not find it! Please help me.

Code JavaScript:

 
function validate(Example) {
  var isGood = true;
  //validate test
  if(document.getElementById('test').value=='')
    {
    isGood = false;
    }
 
  //return true or false
  if (isGood== false)
    {
    alert (isGood);
    }
  return isGood;
 
}
 
 
$(function() {
 
    $('#addquestion').click(function() {
      $('<input id="test" type="text" name="text1" /><br />').appendTo('#to_moreoptions');
 
      if(document.getElementById('formid').value=='vrednost')
          {
          validate('test');
          }
    });
 
});

I will make more simple question. The problem is that 'test' is not passed. The following function alert undefined, but it should alert test.

Code JavaScript:

function validate(Example) {
    var isGood = true;
    alert(Example);
    }
 
$(function() {
    //if I put validate('test') here, it will alert test
    if(document.getElementById('formid').value=='vrednost')
          {
          validate('test');
          }
    });

This is one of those times when I have to say:
Works for me.

    var isGood = true;
    alert(Example);
}
$(function() {
    if (document.getElementById('formid').value == 'vrednost') {
        validate('test');
    }
});
</script>
</head>
<body>
<input type="text" id="formid" value="vrednost">
