JS(JQuery)操作Array的相关方法介绍

1：split 函数将字符串按某个字符分割，将分割后的结果存入字符串数组中
复制代码 代码如下:
function SplitUsersInformation(users) {
var usersArray = users.split(';');
return usersArray;
}
2：substr 函数切割目标字符串
复制代码 代码如下:
currentStr = currentStr .substr(0, currentStr.length - 2);
3：push 方法向Array中添加一条记录
复制代码 代码如下:
var totalUsers = new Array();
function PushItem(name, departmemt) {
var currentUser = new Object();
currentUser.UserName = name;
currentUser.Department = departmemt;
totalUsers.push(currentUser);
}
4：pop 方法从Array的栈中弹出最上面的那条记录
复制代码 代码如下:
var totalUsers = new Array();
var user1 = new Object();
user1.UserName = "haha";
user1.Department = "hahahaha";
var user2 = new Object();
user2.UserName = "lolo";
user2.Department = "lolololo";
totalUsers.push(user1);
totalUsers.push(user2);
totalUsers.pop();
//totalUsers中会剩下user1，因为user2在栈的最上方，被弹出
5：splice 方法从Array中删除指定的某条或者多条记录
复制代码 代码如下:
var totalUsers = new Array();
totalUsers.push(...);
function SpliceItem(name) {
for (var i = 0; i < totalUsers.length; i++) {
if (totalUsers[i].UserName == name) {
totalUsers.splice(i, 1)
}
}
}
