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)

}

}

}
