dojo 对Javascript1.6 的数组操作功能进行了拓展: clearCache () every (arr, callback, thisObject) Determines whether or not every item in arr satisfies the condition implemented by callback. filter (arr, callback, thisObject) Returns a new Array with those items from arr that match the condition implemented by callback. forEach (arr, callback, thisObject) for every item in arr, callback is invoked. indexOf (arr, value, fromIndex, findLast) locates the first index of the provided value in the passed array. lastIndexOf (arr, value, fromIndex) locates the last index of the provided value in the passed array. map
