Code:	function natsort (inputArr) { // http://jsphp.co/jsphp/fn/view/natsort // + original by: Brett Zamir (http://brett-zamir.me) // + improved by: Brett Zamir (http://brett-zamir.me) // + improved by: Theriault // % note 1: This function deviates from PHP in returning a copy of the array instead // % note 1: of acting by reference and returning true; this was necessary because // % note 1: IE does not allow deleting and re-adding of properties without caching // % note 1: of property position; you can set the ini of "phpjs.strictForIn" to true to // % note 1: get the PHP behavior, but use this only if you are in an environment // % note 1: such as Firefox extensions where for-in iteration order is fixed and true // % note 1: property deletion is supported. Note that we intend to implement the PHP // % note 1: behavior by default if IE ever does allow it; only gives shallow copy since // % note 1: is by reference in PHP anyways // - depends on: strnatcmp // * example 1: $array1 = {a:"img12.png", b:"img10.png", c:"img2.png", d:"img1.png"}; // * example 1: $array1 = natsort($array1); // * returns 1: {d: 'img1.png', c: 'img2.png', b: 'img10.png', a: 'img12.png'} var valArr = [], k, i, ret, that = this, strictForIn = false, populateArr = {}; // BEGIN REDUNDANT this.php_js = this.php_js || {}; this.php_js.ini = this.php_js.ini || {}; // END REDUNDANT strictForIn = this.php_js.ini['phpjs.strictForIn'] && this.php_js.ini['phpjs.strictForIn'].local_value && this.php_js.ini['phpjs.strictForIn'].local_value !== 'off'; populateArr = strictForIn ? inputArr : populateArr; // Get key and value arrays for (k in inputArr) { if (inputArr.hasOwnProperty(k)) { valArr.push([k, inputArr[k]]); if (strictForIn) { delete inputArr[k]; } } } valArr.sort(function (a, b) { return that.strnatcmp(a[1], b[1]); }); // Repopulate the old array for (i = 0; i < valArr.length; i++) { populateArr[valArr[i][0]] = valArr[i][1]; } return strictForIn || populateArr; }
