bootstrap的模态简单案例

使用时需添加bootstrap的引用,否则实现不出来效果

<!DOCTYPE html>

<html>
<head>
<meta name="viewport" content="width=device-width" />
<title>Index</title>

注意此处的引用顺序

<link href="~/css/bootstrap.min.css" rel="stylesheet" />
    <script src="~/js/jquery.min.js"></script>
    <script src="~/js/bootstrap.min.js"></script>

这里使用ajax做的登录

<script>
       
        function submita() {
                $.ajax({
                    type: 'post',
                    datatype: 'json',
                    url: '/Home/Login',
                    data: {
                        Email: $('#txtemail').val(),
                        Pwd: $('#txtpwd').val()

                    },
                    success: function (data) {
                        if (data > 0) {
                            alert('登录成功');
                            
                                var m = document.getElementById("d");
                                m.innerHTML = "<div style='float:right' id='d'><ul class='nav navbar-nav'><li class='dropdown active'><a href='#' class='dropdown-toggle' data-toggle='dropdown'>sa<b class='caret'></b></a><ul class='dropdown-menu'><li><a href='#'>设置</a></li><li><a href='/Home/zhuxiao'>退出</a></li></ul></li></ul></div>";
                            
                            $("#myModal").modal("hide");
                        }
                        else {
                            alert('登录失败');

                        }
                        
                    },
                    error: function (err) {
                        alert('错误')
                    }
                })
            }
        
    </script>

 <nav class="navbar navbar-default" role="navigation" style="
       <div class="navbar-header">
           <a class="navbar-brand" href="#" style="margin-bottom:20px;">

               <img src="~/logo-transparent.png" />
           </a>

       </div>
       <div>
           <ul class="nav navbar-nav">
               <li class="dropdown">

                   </ul>
               </li>
               <li >

           <div style="float:right; position:absolute;right:0;top:15px;" id="d">
               <a class="btn" data-toggle="modal" data-target="#myModal">登录</a>

模态代码

 <div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
        <div class="modal-dialog">
            <div class="modal-content">
