                    <div class="modal-body">                 <form action="" class="form center-block" onsubmit="login()">                     <div class="form-group">                         <input type="text" id="username" class="form-control input-lg" placeholder="请输入用户名">                     </div>                     <div class="form-group">                         <input type="password" id="password" class="form-control input-lg" placeholder="请输入密码">                     </div>                     <div class="form-group">                         <button class="btn btn-primary btn-lg btn-block" type="submit">登录</button>                     </div>                 </form>                     </div>          <script type="text/javascript">  function login() {  var un = document.getElementById("username").value;         var pw = document.getElementById("password").value;         if (un == "admin" && pw == "admin") {  window.open("TXL.html", '_blank');             this.window.close();             return true;  }  else {  alert("登录失败");             return false;  }     } </script>

Answer 1

window.open和window.close都会有被浏览器拦截的可能性

建议直接用window.location.href="TXL.html"代替

window.open("TXL.html", '_blank');

this.window.close();

这两行
