For page errors, the easiest thing to think of is to use alert to prompt. However, too many alerts are easily annoying. You can do the following 

<input id="myname" name="myname" >
<p id="errormessage" style="color:red"></p>
<script>
function check(){
    if(${"#myname"}.val()==""){
         $("#errormessage").text("你的名字为必填项！");
       return false；
    }
       return true；
}
</script>
Copy after login
