Remove spaces from an input field with JavaScript

This is a small snippet to remove the spaces from an input field using JavaScript. It can be useful when you want a value without spaces, or when you want to replace the spaces from the input field with other characters.

The JavaScript code:

function stripspaces(input)
{
  input.value = input.value.replace(/\s/gi,"");
  return true;
}

The input field:

<input onkeydown="javascript:stripspaces(this)" name="field_with_no_spaces" type="text" />

The spaces will be stripped from the input field in real-time, as the user types.
