jQuery.trim() capital Q?

or $.trim()

No need for jQuery

JavaScript does have a native .trim() method.

var name = "    John Smith  ";
name = name.trim();

console.log(name); // "John Smith"

Example Here

String.prototype.trim()

The trim() method removes whitespace from both ends of a string. Whitespace in this context is all the whitespace characters (space, tab, no-break space, etc.) and all the line terminator characters (LF, CR, etc.).

or just use $.trim(str)

Why not try this?

html:

<p>
  a b c
</p>

js:

$("p").text().trim();

Try this

  $('input').val($('input').val().trim());
