This article mainly brings you a jquery implementation of the user login interface (example explanation). The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look, I hope it can help everyone.

The example is as follows:

<!DOCTYPE html>
<html>
  <head>
    <meta charset="UTF-8">
    <title></title>
  </head>
  <script src="js/jquery-1.8.0.min.js"></script>
  <script>
    var cnresu = false;
    $(function(){
      $("input[name=&#39;uname&#39;]").blur(function(){//blur从链接上移开焦点(鼠标离开框时)
        var unamestr = $(this).val();
        var regstr = /^[\u4e00-\u9fa5]{2,4}$/;
        if(!regstr.test(unamestr)){
          $(this).parent().next("dd").html("必须是2-4个汉字");
          cnresu = false;
          return;
        }
        cnresu = true;
      });
      $("input[name=&#39;uname&#39;]").focus(function(){//focus给予链接焦点(鼠标点中框时)
        $(this).css("border","solid 1px #dddddd");
        //$(this).val("");
        $(this).parent().next("dd").html("");
      });
    });
  </script>
  <style>
    #home{
      width: 600px;
      height: 300px;
      margin: auto;
      background-color: #7FFFD4;
    }
    #head{
      padding-top: 20px;
      height: 100px;
    }
    .dl1{
      clear: both;
    }
    .dl1 dt{
      float: left;
      text-align: right;
      width: 150px;
      height: 30px;
      line-height: 30px;
    }
    .dl1 dd{
      float: left;
      height: 30px;
      line-height: 30px;
    }
    #foot{
      text-align: center;
    }
    h1{
      padding-top: 20px;
      text-align: center;
      color: bisque;
    }
  </style>
  <body>
    <p id="home">
      <h1>用户登陆</h1>
      <p id="head">
      <form action="biaodan.html" name="regform" method="post" >
        <dl class="dl1">
          <dt>用户名 : </dt>
          <dd><input type="text" name="uname"/></dd>
          <dd id="erroruname"></dd>
        </dl>
        <dl class="dl1">
          <dt>密码 : </dt>
          <dd><input type="password"/></dd>
          <dd id="errorpass"></dd>
        </dl>
      </p>
        <p id="foot">
          <input type="submit" value="提交"/>
          <input type="reset" value="重置"/>
        </p>
      </form>
    </p>
  </body>
</html>
