splice 方法
從一個數(shù)組中移除一個或多個元素，如果必要，在所移除元素的位置上插入新元素，返回所移除的元素。
arrayObj.splice(start, deleteCount, [item1[, item2[, . . . [,itemN]]]])

參數(shù)
arrayObj 必選項。一個 Array 對象。

start

必選項。指定從數(shù)組中移除元素的開始位置，這個位置是從 0 開始計算的。

deleteCount

必選項。要移除的元素的個數(shù)。

item1, item2,. . .,itemN

必選項。要在所移除元素的位置上插入的新元素。

說明
splice 方法可以移除從 start 位置開始的指定個數(shù)的元素并插入新元素，從而修改 arrayObj。返回值是一個由所移除的元素組成的新 Array 對象。
