前言

Bootstrap：Twitter推出的一个开源的用于前端开发的工具包。它由Twitter的设计师Mark Otto和Jacob Thornton合作开发，是一个CSS/HTML框架

官方网站：http://www.bootcss.com/

1.Bootstrap Modals（模态框）基本用法

使用bootstrap之前需要应用jquery.js和bootstrap.js以及bootstrap.css 注意：最新版的bootstrap需要和jquery1.9以上版本配合使用

    <!-- 按钮触发模态框 -->
    <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" id="myModalLabel">
                        模态框（Modal）标题
                    </h4>
                </div>
                <div class="modal-body">
                    在这里添加一些文本
                </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>
        </div>
    </div>

当我们点击button的时候会触发Modal,效果如下图所示

2.0先看我们的封装代码

$(function () {
    if ($.fn.modal) {
        $.fn.modal.defaults.spinner = $.fn.modalmanager.defaults.spinner =
    '<div class="loading-spinner" style="width: 200px; margin-left: -100px;">' +
    '<div class="progress progress-striped active">' +
      '<div class="progress-bar" style="width: 100%;"></div>' +
    '</div>' +
    '</div>';

        $.fn.modalmanager.defaults.resize = true;
    }

    window.Modal = function () {
        var _tplHtml = '<div class="modal created-modal" id="[Id]">' +
                                        '<div class="modal-header">' +
                                            '<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>' +
                                            '<h5 class="modal-title"><i class="icon-exclamation-sign"></i> [Title]</h5>' +
                                        '</div>' +
                                        '<div class="modal-body small">' +
                                            '<p>[Message]</p>' +
                                        '</div>' +
                                        '<div class="modal-footer" >' +
                                            '<button type="button" class="btn btn-primary ok" data-dismiss="modal">[BtnOk]</button>' +
                                            '<button type="button" class="btn btn-default cancel" data-dismiss="modal">[BtnCancel]</button>' +
                                        '</div>' +
                            '</div>';

        var _tplLoadHtml = '<div class="modal created-modal" id="[Id]">' +
                                                '<div class="modal-header">' +
                                                    '<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>' +
                                                    '<h5 class="modal-title">[Title]</h5>' +
                                                '</div>' +
                                                '<div class="modal-body small">' +
                                                    '<iframe src="[Url]" frameborder="0" width="100%" height="[Height]px" style="padding:0px; margin:0px;"></iframe>' +
                                                '</div>' +
                                        '</div>';
