Question

我正在使用Phonegap，我想使用jquery mobile在pinch上使用放大/缩小选项。我已经尝试过jgesture和锤子插件进行缩放。我在这段代码中错在哪里？

<html>
    <head>
        <meta charset="utf-8" />
        <meta name="format-detection" content="telephone=no" />
        <!-- WARNING: for iOS 7, remove the width=device-width and height=device-height attributes. See https://issues.apache.org/jira/browse/CB-4323 -->
        <meta name="viewport" content="user-scalable=yes, initial-scale=1, maximum-scale=1, minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi" />
        <link rel="stylesheet" type="text/css" href="css/index.css" />
        <link rel="stylesheet" type="text/css" href="css/jquery.mobile-1.4.1.min.css" />
        <title>Hello World</title>
        <script type="text/javascript" src="js/jquery-1.9.1.min.js"></script>
        <script>
                 $(document).bind("mobileinit", function(){
      $.mobile.metaViewportContent = "width=device-width, minimum-scale=1, maximum-scale=2";
});
        </script>
        <script type="text/javascript" src="js/jquery.mobile-1.4.1.min.js"></script>
    </head>
    <body>
        <div class="app">
            <h1>PhoneGap</h1>
            <div id="deviceready" class="blink">
                <p class="event listening">Connecting to Device</p>
                <p class="event received">Device is Ready</p>
            </div>
        </div>
        <script type="text/javascript" src="phonegap.js"></script>
        <script type="text/javascript" src="js/index.js"></script>
        <script type="text/javascript">
            app.initialize();

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

使用hammer.js捏，pinchin，pinchout

以下是github上API的事件文档：

https://github.com/EightMedia/hammer.js/wiki/Getting-Started

另外，你基本上使它不是用户可扩展的......：

initial-scale=1, maximum-scale=1, minimum-scale=1,

这一行：

<meta name="viewport" content="user-scalable=yes, initial-scale=1, maximum-scale=1,
minimum-scale=1, width=device-width, height=device-height, target-densitydpi=device-dpi"/>

然后使用jquery再次设置它：

$.mobile.metaViewportContent = "width=device-width, minimum-scale=1, maximum-scale=2";

不好，请在此处阅读： https://developer.mozilla.org/en-US/docs/Web/HTML/Element/meta
