Use jquery to click the Enter key to achieve the login effect (detailed tutorial)

Below I will share with you a jquery method of clicking the Enter key to achieve the login effect and default focus. It has a good reference value and I hope it will be helpful to everyone.

When I was doing project login recently, I had to click the login button every time to enter the corresponding page, which gave the user a very bad experience, so I added the use of the Enter key to log in.

Method:

   登录 
 $(function () { $('#username_txt').focus(); //用户点击按钮 $("#login_btn").click(function () { //获取用户名 var username = $('#username_txt').val(); //获取密码 var userpass = $('#userpass_txt').val(); if (username == "" || userpass == "") { alert("用户名密码不能为空！"'); } else { //调用登录方法 $.ajax({ }); } }); $("body").keydown(function(event) { if (event.keyCode == "13") {//keyCode=13是回车键 $("#login_btn").click(); } }); });

Final rendering:

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
