jQuery:Select a text range (input/textarea)

select-text-range.js

//USE CASE
$('#q').selectRange(0, 10);
$('#q').selectRange(searchVal.indexOf('{'), (searchVal.indexOf('}')+1));


//Source here : http://plugins.jquery.com/project/selectRange

$.fn.selectRange = function(start, end) {
    var e = document.getElementById($(this).attr('id')); // I don't know why... but $(this) don't want to work today :-/
    if (!e) return;
    else if (e.setSelectionRange) { e.focus(); e.setSelectionRange(start, end); } /* WebKit */ 
    else if (e.createTextRange) { var range = e.createTextRange(); range.collapse(true); range.moveEnd('character', end); range.moveStart('character', start); range.select(); } /* IE */
    else if (e.selectionStart) { e.selectionStart = start; e.selectionEnd = end; }
};

Also, super useful:

$.fn.setCaretPos = function(index) {
    $(this).selectRange(index, index);
};
