As of JavaScript 1.8.1 (ES5) you can use normal string.trim()

var orig = "   foo  ";
alert( orig.trim() );

// "foo"

You're getting spaces because your options' text is on a separate line in HTML with indenting. You could remove them first:

$("#users option").text(function(i, text) {
    return $.trim(text);
});

As for the placeholder, use .attr("placeholder", ...) instead of .val(...):

input = $( "<input>" )
    .appendTo( wrapper )
    .attr( "placeholder", value )

Trim left and right spaces of a string

string.replace(/^\s\s*/, '').replace(/\s\s*$/, '');

Regarding to placeholder, you can try jQuery-Placeholder
