Try this:

function trim(el) {
    var trimmedValue = el.val().trim();
    el.val(trimmedValue);
}

Your syntax for .trim() is wrong. To trim a input's value you don't need any regex, just try to change this:

$(.input).text().trim();

to this:

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

input is not a class, so you don't have to put the dot before it. Then you have to include it inside ' '. The value of an input is given by val() method, not text().

This will only trim the input's value, you have to use this inside a function in order to make it works properly, as in the example above.
