Due to the needs of the project, I made a super simple pop-up box, which will pop up as soon as the page is opened. Since the project director said that it should be as small as possible (less introduction of encapsulated file packages), native js was used (I found that jQuery is basically used on the Internet). Without further ado, let’s get into the code
<!DOCTYPE html>
<head>
<meta charset="utf-8">
<title>登录确定提醒</title>
<style>
html,
body {
margin: 0;
padding: 0;
font-family: "微软雅黑";
}
.wrap-dialog {
position: fixed;
top: 0;
left: 0;
width: 100%;
height: 100%;
font-size: 16px;
text-align: center;
background-color: rgba(0, 0, 0, .7);
z-index: 999;
}
.dialog {
top: 0;
left: 0;
position: relative;
/*margin: 10% auto;*/
width: 300px;
background-color: #FFFFFF;
border-radius: 2px;
}
.dialog .dialog-header {
height: 20px;
padding: 10px;
background-color: #F8F8F8;
border-bottom: 1px solid #eee;
text-align: left;
}
.dialog-title{
display: inline-block;
width: 50px;
margin-left: 0;
}
.dialog .dialog-body {
height: 30px;
padding: 20px;
}
.dialog .dialog-footer {
padding: 8px;
background-color: #f5f5f5;

.dialog-btn {

border-radius: 2px;

line-height: 28px;

.dialog-hide {
display: none;

.dialog-ml50 {
margin-left: 50px;

}
.closeBtn{

text-align: center;
/*background: red;*/

.closeBtn:hover{

<script>
window.onload=function(){

function submitHand(){
function submitBtn() {
alert("确定");

function closeBtn() {
alert("取消");

confirm("确认登录？", submitBtn, closeBtn);
}
//页面打开自动弹出
