    按钮开启
</button>

        <a href="javascript:void(0)" class="btn btn-default" onclick="openMotai()">JS函数开启</a>

        <script type="text/javascript">
            function openMotai(){
                alert("准备开启");
                $("#myModal1").modal('show');  //手动开启
                alert("准备关闭");
                $("#myModal1").modal('hide');  //手动关闭
                alert("准备开启");
                $("#myModal1").modal();  //手动开启
            }
        </script>

        <div class="modal fade" id="myModal1" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-header">
　　　　　　　　　　　　　　<!--关闭符号-->

                        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">
                    &times;
                </button>
                        <h4 class="modal-title" id="myModalLabel">
                    模态框（Modal）标题
                </h4>
                    </div>
                    <div class="modal-body">
                        username:<input type="text" name="" id="" value="" /><br /> password:
                        <input type="password" name="" />
                    </div>
                    <div class="modal-footer">

                    </div>
                </div>
                <!-- /.modal-content -->
            </div>
            <!-- /.modal -->
        </div>
    </body>

</html>

2.有时候我们希望点击esc或者点击模态框外部的时候不会关闭

<!DOCTYPE html>
<html>

    <head>
        <meta charset="utf-8">
        <title>Bootstrap 实例 - 模态框（Modal）插件</title>
        <link rel="stylesheet" href="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/css/bootstrap.min.css">
        <script src="http://cdn.static.runoob.com/libs/jquery/2.1.1/jquery.min.js"></script>
        <script src="http://cdn.static.runoob.com/libs/bootstrap/3.3.7/js/bootstrap.min.js"></script>
    </head>

    <body>

        <h2>创建模态框（Modal）</h2>
        <!-- 按钮触发模态框 -->
        <button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal1">
    按钮开启
</button>

        <a href="javascript:void(0)" class="btn btn-default" onclick="openMotai()">JS函数开启</a>

        <script type="text/javascript">
            function openMotai(){
                /*alert("准备开启");
                $("#myModal1").modal('show');  //手动开启
                alert("准备关闭");
                $("#myModal1").modal('hide');  //手动关闭
                alert("准备开启");
                $("#myModal1").modal();  //手动开启*/
                $("#myModal1").modal({backdrop: 'static', keyboard: false});  //手动开启
                
                
            }
        </script>

        <!-- 模态框（Modal） -->
        <div class="modal fade" id="myModal1" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
            <div class="modal-dialog">
                <div class="modal-content">
                    <div class="modal-header">

　　　　　　　　　　　　　　<!-- 关闭符号(叉号) -->

                        <button type="button" class="close" data-dismiss="modal" aria-hidden="true">
                    &times;
                </button>
                        <h4 class="modal-title" id="myModalLabel">
                    模态框（Modal）标题
                </h4>
                    </div>
                    <div class="modal-body">
                        username:<input type="text" name="" id="" value="" /><br /> password:
                        <input type="password" name="" />
                    </div>
                    <div class="modal-footer">
                        <button type="button" class="btn btn-default" data-dismiss="modal">关闭
                </button>
                        <button type="button" class="btn btn-primary">
                    提交更改
                </button>
                    </div>
                </div>
                <!-- /.modal-content -->
            </div>
            <!-- /.modal -->
        </div>
    </body>

</html>

分析:

$(‘#myModal’).modal({backdrop: ‘static’, keyboard: false});
其中，backdrop：’static’指的是点击背景空白处不被关闭；
keyboard:false指的是触发键盘esc事件时不关闭。

另一种方式是直接在模态框标签加::

<div class="modal fade" id="myModal" role="dialog"
data-backdrop="static" data-keyboard="false" aria-labelledby="myModalLabel" aria-hidden="true">
