Today we will introduce to you how to use JavaScript to realize the pop-up prompt box in the lower right corner!
This articleexplains with examplesThe example code of the pop-up advertising information box in the lower right corner of the web page is shared with everyone for your reference. The specific content is as follows

Specific code:
<!DOCTYPE html>

<style type="text/css">
#winpop {
width:200px;
height:0px;

right:0;
bottom:0;
border:1px solid #666;
margin:0;
padding:1px;
overflow:hidden;
display:none;
}
#winpop .title{
width:100%;

text-align:center;
font-size:12px;
}
#winpop .con{

<script type="text/javascript">
function tips_pop(){
var MsgPop=document.getElementById("winpop");
var popH=parseInt(MsgPop.style.height);//將對(duì)象的高度轉(zhuǎn)化為數(shù)字
if(popH==0){
MsgPop.style.display="block";//顯示隱藏的窗口
show=setInterval("changeH('up')",2);
}
else{
hide=setInterval("changeH('down')",2);
}
}
function changeH(str){
var MsgPop=document.getElementById("winpop");
var popH=parseInt(MsgPop.style.height);
if(str=="up"){
if(popH<=100){
MsgPop.style.height=(popH+4).toString()+"px";
}
else{
clearInterval(show);
}
}
if(str=="down"){
if(popH>=4){
MsgPop.style.height=(popH-4).toString()+"px";
}
else{
clearInterval(hide);
MsgPop.style.display="none"; //隱藏p
}
}
}
window.onload=function(){
var oclose=document.getElementById("close");
var bt=document.getElementById("bt");
document.getElementById('winpop').style.height='0px';
setTimeout("tips_pop()",3000);
oclose.onclick=function(){tips_pop()}
bt.onclick=function(){tips_pop()}
}
</script>
<body>
<p id="silu">
<button id="bt">3秒后會(huì)在右下角自動(dòng)彈出窗口，如果沒(méi)有彈出請(qǐng)點(diǎn)擊這個(gè)按鈕</button>
</p>
<p id="winpop">
<p class="title">您有新的短消息！<span class="close" id="close">X</span></p>
<p class="con">1條未讀信息(</p>
</p>
</body>
</html>The above code implements the functions we need. Here is a brief introduction to the implementation process.
Implementation principle:
The principle is very simple. Here is a brief introduction step by step:
1. Let the window be located in the lower right corner of the web page:
The implementation code is as follows:
#winpop {
width:200px;
height:0px;
position:absolute;
right:0;
bottom:0;
border:1px solid #666;
margin:0;
padding:1px;
overflow:hidden;
display:none;
}The above code sets the windpop element to absolute positioning, especially its right and bottom attribute values ????are set to 0, so that Ensure that it is located in the lower right corner of the web page, and also set its height to 0px, which means it is hidden by default.
2. How to show and hide:
The changeH() function is called every specified time through the timer function setInterval(). This function can be based on the passed value. Constantly set the height of windpop, so as to achieve the effect of this window appearing and disappearing smoothly. The principle is roughly the same as above, so I won’t introduce it much here.
Summary:
#This article provides a better explanation to friends through examples and an introduction to the implementation process and principles. I have used JavaScript to realize the method of popping up the prompt box in the lower right corner. I believe everyone has a better understanding of this! Hope it helps with your work!
