Code:	function ksort (inputArr, sort_flags) { // http://jsphp.co/jsphp/fn/view/ksort // + original by: GeekFG (http://geekfg.blogspot.com) // + improved by: Kevin van Zonneveld (http://kevin.vanzonneveld.net) // + 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 // % note 3: Since JS objects' keys are always strings, and (the // % note 3: default) SORT_REGULAR flag distinguishes by key type, // % note 3: if the content is a numeric string, we treat the // % note 3: "original type" as numeric. // - depends on: i18n_loc_get_default // - depends on: strnatcmp // * example 1: data = {d: 'lemon', a: 'orange', b: 'banana', c: 'apple'}; // * example 1: data = ksort(data); // * results 1: {a: 'orange', b: 'banana', c: 'apple', d: 'lemon'} // * example 2: ini_set('phpjs.strictForIn', true); // * example 2: data = {2: 'van', 3: 'Zonneveld', 1: 'Kevin'}; // * example 2: ksort(data); // * results 2: data == {1: 'Kevin', 2: 'van', 3: 'Zonneveld'} // * returns 2: true var tmp_arr = {}, keys = [], sorter, i, k, that = this, strictForIn = false, populateArr = {}; switch (sort_flags) { case 'SORT_STRING': // compare items as strings sorter = function (a, b) { return that.strnatcmp(a, b); }; break; case 'SORT_LOCALE_STRING': // compare items as strings, based on the current locale (set with i18n_loc_set_default() as of PHP6) var loc = this.i18n_loc_get_default(); sorter = this.php_js.i18nLocales[loc].sorting; break; case 'SORT_NUMERIC': // compare items numerically sorter = function (a, b) { return ((a + 0) - (b + 0)); }; break; // case 'SORT_REGULAR': // compare items normally (don't change types) default: sorter = function (a, b) { var aFloat = parseFloat(a), bFloat = parseFloat(b), aNumeric = aFloat + '' === a, bNumeric = bFloat + '' === b; if (aNumeric && bNumeric) { return aFloat > bFloat ? 1 : aFloat < bFloat ? -1 : 0; } else if (aNumeric && !bNumeric) { return 1; } else if (!aNumeric && bNumeric) { return -1; } return a > b ? 1 : a < b ? -1 : 0; }; break; } // Make a list of key names for (k in inputArr) { if (inputArr.hasOwnProperty(k)) { keys.push(k); } } keys.sort(sorter); // 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; }
