JS(JQuery)操作Array的相關方法介紹_javascript技巧

1：split 函數將字串以某個字元分割，將分割後的結果存入字串陣列中

複製程式碼 程式碼如下:

function SplitUsersInformation(users) {
    var usersArray = users.split(';');
  > 🎜>
2：substr 函數切割目標字串

複製程式碼 程式碼如下:

程式碼如下:

currentStr = currentStr .substr(0, currentStr.length - 2);

3：push 方法向Array中添加一條記錄

複製程式碼 程式碼如下:

var totalUsers = new Array();
function PushItem(name, departmemt) {

function PushItem(name, departmemt) { ();
    currentUser.UserName = name;
    currentUser.Department = departmemt;
    totalUsers.push(currentUser}的堆疊中彈出最上面的那筆記錄

複製程式碼 程式碼如下: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..F() ;
//totalUsers中會剩下user1，因為user2在堆疊的最上方，被彈出


5：splice 方法從Array中刪除指定的某條或多筆記錄

複製程式碼

程式碼如下:var totalUsers = new Array();

var totalUsers = new Array();

to (...);

function SpliceItem(name) {    for (var i = 0; i        .splice (i, 1)
        }
    }
}
