splice 方法可以移除从 start 位置开始的指定个数的元素并插入新元素,从而修改 arrayObj。返回值是一个由所移除的元素组成的新 Array 对象。 要求 版本5.5 Js代码 Array.prototype.clear=function(){ this.length=0; } Array.prototype.insertAt=function(index,obj){ this.splice(index,0,obj); } Array.prototy...

An array of items to be displayed in the grid. The option should be used to provide static data. Use the controller option to provide non static data.autoload (default false)A boolean value specifying whether controller.loadData will be called when grid is rendered....
You can also pass initial values, in any order. With lots of values, it's faster to load them all at once than one at a time. var queue = new PriorityQueue({ initialValues: [ 1, 2, 3 ] }) Strategies We can implement this with a regularArray. We'll keep it sorted inversely, ...
