function uksort (inputArr, sorter) { // http://jsphp.co/jsphp/fn/view/uksort // + original by: Brett Zamir (http://brett-zamir.me) // + improved by: Brett Zamir (http://brett-zamir.me) // % note 1: The examples are correct, this is a new way // % note 2: This function deviates from PHP in returning a copy of the array instead // % note 2: of acting by reference and returning true; this was necessary because // % note 2: IE does not allow deleting and re-adding of properties without caching // % note 2: of property position; you can set the ini of "phpjs.strictForIn" to true to // % note 2: get the PHP behavior, but use this only if you are in an environment // % note 2: such as Firefox extensions where for-in iteration order is fixed and true // % note 2: property deletion is supported. Note that we intend to implement the PHP // % note 2: behavior by default if IE ever does allow it; only gives shallow copy since // % note 2: is by reference in PHP anyways // * example 1: data = {d: 'lemon', a: 'orange', b: 'banana', c: 'apple'}; // * example 1: data = uksort(data, function (key1, key2){ return (key1 == key2 ? 0 : (key1 > key2 ? 1 : -1)); }); // * results 1: data == {a: 'orange', b: 'banana', c: 'apple', d: 'lemon'} // * returns 1: true var tmp_arr = {}, keys = [], i = 0, k = '', strictForIn = false, populateArr = {}; if (typeof sorter === 'string') { sorter = this.window[sorter]; } // Make a list of key names for (k in inputArr) { if (inputArr.hasOwnProperty(k)) { keys.push(k); } } // Sort key names try { if (sorter) { keys.sort(sorter); } else { keys.sort(); } } catch (e) { return false; } // 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; // Rebuild array with sorted key names for (i = 0; i < keys.length; i++) { k = keys[i]; tmp_arr[k] = inputArr[k]; if (strictForIn) { delete inputArr[k]; } } for (i in tmp_arr) { if (tmp_arr.hasOwnProperty(i)) { populateArr[i] = tmp_arr[i]; } } return strictForIn || populateArr; }
