How check inputs for current time in 24 hours format

Albert3162 · Oct 23, 2003

Hi,

I'm trying to check what user insert in the input field
as current time user can insert only 4 digits (format like 1239 or 0057, 2355)

HI,

I would check for

value.length = 4
and
isNaN(parseInt(value))

I hope that does it for you.
If you need more help post what you've got and I'll fit that in it for you.

Break it down:
first digit must be 0-2
second digit must be 0-9
third digit must be 0-5
fourth digit must be 0-9

Welcome to regular expression land

put this in your <head><script>..

Code:

function checkTime(textObj) {
  var str = textObj.value;
  var regex = /^[0-2][0-9][0-5][0-9]$/;
  if (!regex.test(str)) {
    alert(&quot;Please make sure time is in this format 1423&quot;);
    textObj.focus();
  }
}

and then you could use it like so:

Code:

<input type=&quot;text&quot; name=&quot;timeBox1&quot; size=&quot;6&quot; onblur=&quot;checkTime(this);&quot; />
