The following is an example of using js to implement a message board that I compiled for you. Interested students can take a look.
<!DOCTYPE html>
<html>
<head>
<style>
#ly{
width:auto;
height: auto;
}
</style>
<meta charset="utf-8" />
<title></title>
</head>
<body>
<input type="text" id="tx" /><button value="留言" id="bt" >留言</button>
<div id="ly"></div>
<script>
var tx=document.getElementById("tx");
var ly=document.getElementById("ly");
var obt=document.getElementById("bt");
function tj(){
var oli =document.createElement("a");
oli.innerHTML=tx.value+'删除'+'</br>';
oli.onclick=function ck(){
ly.removeChild(this);
}
oli.href="#";
if(ly.firstChild){
ly.insertBefore(oli,ly.firstChild);
}
else{ly.firstChild=oli;}
ly.appendChild(oli);
};
obt.onclick =function a(){tj();}
</script>
</body>
</html>The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
