标签:data-   代码   关闭   mod   show   ack   元素   xtend   jquery   

未封装前:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="css/bootstrap.min.css">
    <script src="js/jquery.min.js"></script>
    <script src="js/bootstrap.js"></script>
</head>
<body>

<button type="button" id="modalBtn" class="btn btn-primary">点击弹出modal</button>

<div class="modal fade" id="myModal">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title">Modal 标题</h4>
            </div>
            <div class="modal-body">
                <p>内容&hellip;</p>
                <p>内容&hellip;</p>
                <p>内容&hellip;</p>

            </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">确定</button>
            </div>
        </div>
    </div>
</div>


<script type="text/javascript">
    $(function(){
        var $m_btn = $(#modalBtn);
        var $modal = $(#myModal);
        $m_btn.on(click, function(){
            $modal.modal({backdrop: static});
        });

        $modal.on(show.bs.modal, function(){
            var $this = $(this);
            var $modal_dialog = $this.find(.modal-dialog);
            // 关键代码,如没将modal设置为 block,则$modala_dialog.height() 为零
            $this.css(display, block);
            $modal_dialog.css({margin-top: Math.max(0, ($(window).height() - $modal_dialog.height()) / 2) });
        });

    });
</script>

</body>
</html>

封装后:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
    <link rel="stylesheet" href="css/bootstrap.min.css">
    <script src="js/jquery.min.js"></script>
    <script src="js/bootstrap.js"></script>
</head>
<body>

<button type="button" id="modalBtn" class="btn btn-primary">点击弹出modal</button>

<div class="modal fade" id="myModal">
    <div class="modal-dialog">
        <div class="modal-content">
            <div class="modal-header">
                <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
                <h4 class="modal-title">Modal 标题</h4>
            </div>
            <div class="modal-body">
                <p>内容&hellip;</p>
                <p>内容&hellip;</p>
                <p>内容&hellip;</p>

            </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">确定</button>
            </div>
        </div>
    </div>
</div>

<script type="text/javascript">
    $(function(){
        $(#myModal).myfunction({
            $m_btn:$(#modalBtn),  //触发事件元素
            $modal:$(#myModal),   //响应事件元素
            eventType:click     //事件类型
        });
    });
    ;(function ($) {
        $.fn.myfunction=function (options) {
            var defaults={
                $m_btn : $(#modalBtn),
                $modal : $(#myModal),
                eventType:click
            };
            var setting=$.extend({},defaults,options);
            this.each(function(){
                var my_btn = setting.$m_btn;
                var _modal = setting.$modal;
                var _event = setting.eventType;
                my_btn.on(_event, function(){
                    _modal.modal({backdrop: static});
                });

                _modal.on(show.bs.modal, function(){
                    var $this = $(this);
                    var $modal_dialog = $this.find(.modal-dialog);
                    $this.css(display, block);
                    $modal_dialog.css({margin-top: Math.max(0, ($(window).height() - $modal_dialog.height()) / 2) });
                });
            });
        }
    })(jQuery);
</script>

</body>
</html>
