This is one of the easiest way i found :), it uses jquery hope it helps, it uses your function The input have to be only:

This automatically change all inputs, or you can asign to a class

function trim_text(el) {
    el.value = el.value.
    replace(/(^\s*)|(\s*$)/gi, ""). // removes leading and trailing spaces
    replace(/[ ]{2,}/gi, " "). // replaces multiple spaces with one space
    replace(/\n +/, "\n"); // Removes spaces after newlines
    return;
}
$(function(){
  $("textarea").change(function() {
    trim_text(this);
  });

  $("input").change(function() {
    trim_text(this);
  });
});
