基于bootstrap的模态框使用

使用步骤两步

1:按顺序引入以下三个文件

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

2:在页面中copy下面的代码

<button class="btn btn-primary btn-lg" data-toggle="modal" data-target="#myModal">开始演示模态框</button>

<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-hidden="true">&times;</button>
                <h4 class="modal-title text-center" id="myModalLabel">标题是什么</h4>
            </div>
            <div class="modal-body">
                写你HTML文本
            </div>
            <div class="modal-footer">
                <button type="button" class="btn btn-default" data-dismiss="modal">取消</button>
                <button type="button" class="btn btn-primary">保存添加</button>
            </div>
        </div><!-- /.modal-content -->
    </div><!-- /.modal -->
</div>

简单吧,模态框就是需要一个触发,在触发模态框的html元素加入以下属性data-toggle="modal" data-target="#myModal"

观察以下就会发现 这个data-target="#myModal"中的myModal就是模态框所在div的id <div class="modal fade" id="myModal".............>
