【问题标题】：Pageshow not triggered after changepage更改页面后未触发页面显示
【发布时间】：2013-04-18 12:24:46
【问题描述】：

我正在使用 jQuery Mobile，我想在用户单击主页上的按钮后将浏览器重定向到另一个页面。为此，我写道：

$.mobile.changePage("album-search-results.html",{
               data:{area:searchArea, value:searchValue},
               transition: "pop"
           });

它运行良好，它加载了正确的页面，甚至在 URL 上放置了正确的值。不幸的是，没有触发 pageshow 事件：

    <!DOCTYPE html>
<html>
<head>


    <meta name="viewport" content="width=device-width, initial-scale=1">

    <script src="http://code.jquery.com/jquery-1.8.2.min.js"></script>
    <script src="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.js"></script>
    <link rel="stylesheet" href="http://code.jquery.com/mobile/1.3.0/jquery.mobile-1.3.0.min.css" />
</head>

<body>
    <div data-role = "page" data-theme = "d" id = "SearchResults">

        <div data-role = "header">
            <h1>Aggregator</h1>
        </div>

        <div data-role = "content">

        </div>
    </div>

    <script type="text/javascript">
        $("#SearchResults").on("pageshow",function(event, ui){
            console.log(ui.prevPage);

        });

    </script>
</body>
</html>

当我从上一个页面加载此页面时，控制台始终为空。怎么了？谢谢

我以为 pageshow 只是目标文档的一个事件？ developer.mozilla.org/en-US/docs/Web/Events/pageshow

解决方案

解决方案很简单，将脚本块移动到页面 div 内。在您的情况下，脚本块被丢弃。基本上改成这样：

发件人：

<body>
    <div data-role = "page" data-theme = "d" id = "SearchResults">

        <div data-role = "header">
            <h1>Aggregator</h1>
        </div>

        <div data-role = "content">

        </div>
    </div>

    <script type="text/javascript">
        $("#SearchResults").on("pageshow",function(event, ui){
            console.log(ui.prevPage);

        });

    </script>
</body>

收件人：

<body>
    <div data-role="page" data-theme="d" id="SearchResults">
        <div data-role = "header">
            <h1>Aggregator</h1>
        </div>
        <div data-role = "content">

        </div>
        <script>
            $(document).on("pageshow","#SearchResults",function(event, ui){
                console.log(ui.prevPage);
            });
        </script>       
    </div>
</body>

        <script>
            $(document).on('click', '#change-page', function(){       
                $.mobile.changePage("album-search-results.html",{
                    data:{area:"asda", value:"1"},
                    transition: "pop"
                });
            });                 
        </script>
    </head>
    <body>
        <div data-role="page" id="index">
            <div data-theme="a" data-role="header">
                <h3>
                    First Page
                </h3>
                <a href="#second" class="ui-btn-right">Next</a>
            </div>

            <div data-role="content">
                <a data-role="button" id="change-page">Change Page</a>
            </div>

            <div data-theme="a" data-role="footer" data-position="fixed">

            </div>
        </div>    
    </body>
</html>
