使用pop()这个函数可以从数组中删除末尾的元素,shift方法可以删除数组中第一个元素.这些都是js中自带的函数,如果不使用这些函数的话,自己写的代码效率会很低的. <html> <head> <title>数组的字符串表示</title> <script type="text/javascript"> function B(){ var names1=["zhangsan1","lisi1&q
/*从数组中删除指定定数据var somearray = ["mon", "tue", "wed", "thur"]somearray.removeByValue("tue");//somearray will now have "mon", "wed", "thur"*/Array.prototype.removeByValue = functi

我记得我大学学java的时候,怎么就是搞不明白这三种排序方法,也一直不会,现在我有发过来学习下这三种方法并记录下来. 首先说说冒泡排序方法:冒泡排序方法就是把数组中的每一个元素进行比较,如果第i个元素大于第i+1元素,那么就要把二个数字进行交换,这样经过反复的比较就可以将一根数组按由小到大的顺序进行排序. //冒泡排序方法 public class maopao { public static void main(String[] args) { int score[] = {56,85,96,
