I need a regular expression to validate my address field, the condns are...
1. Address field must not start with and empty space (also should not be empty)
2. Address field can contain any alpha numeric characters (Only Capital Letters) and any kind of symbols and it should start with one of the Alphanumeric charcters
3. It can contain any number of spaces in between the words (just like a sentence...)
4. It shud not exceed 200 char.

Thank You,
Steve

This should work:

<body>

  <input type="text" onblur="checkIt(this.value)">

</body>

<script>

function checkIt(testStr) {
  if( !(testStr.length < 200 && testStr.match(/^[a-zA-Z0-9]/))) {
        alert(" not OK");
      }
      else {
        alert("OK");
      }
}

</script>

Whoops I missed the caps condition...

ths is a user friendly way of doing it:

<body>

  <input type="text" onblur="this.value=this.value.toUpperCase(); checkIt(this.value);">

</body>

<script>

function checkIt(testStr) {
  if( !(testStr.length < 200 && testStr.match(/^[a-zA-Z0-9]/))) {
        alert(" not OK");
      }
      else {
        alert("OK");
      }
}

</script>

It is not working...
Its not matching any proper address...
I tried:
123 ADFOME DSDFD
DFDSFEG SDFSDLKL & SDFJDLSF
SDFGF%SDF 34343 & SDFDSF
the above strings should result in success...

Stings I dont want:
 DFDSFEFS SDFDSF (space as first char)
""(empty string)
etc.

Here my proposal:



<input type=text name="Address" maxLength="200" onBlur="checkAddr(this)">
<script>
function checkAddr(theField){
  if(!theField.value.match(/^[A-Z0-9][A-Z0-9\%\&\.\ ]+$/)){
    alert("Enter Address.");
    theField.select();
    theField.focus();
    return false;
  }
}
</script>
