Question

我正在尝试使用jQuery mobile和phonegap开发混合应用程序，我想实现一个支持地理位置的googlemap。因为我已经做了一些编码但是在运行应用程序时它只是给了我一个ajax加载器它是没有停止，任何人都可以帮助我找到错误..我已经尝试了一些jQuery移动演示，但没有一个正常工作。我的代码在下面

Answer 1

jquery.ui.map没有方法getCurrentPosition，您必须自己实施。

请参阅http://code.google.com/p/jquery-ui-map/wiki/Examples#Example_get_user_position以获取示例

<强>＆LT;编辑＆gt;

链接的示例似乎是错误的，至少这个版本的jquery.ui.map是错误的

使用：

( function($) {

    $.extend($.ui.gmap.prototype, {

            /**
             * Gets the current position
             * @a: function(status, position)
             * @b:object, see https://developer.mozilla.org/en/XPCOM_Interface_Reference/nsIDOMGeoPositionOptions
             */
            getCurrentPosition: function(callback, geoPositionOptions) {
        if ( navigator.geolocation ) {
            navigator.geolocation.getCurrentPosition ( 
                function(result) {
                    callback(result, 'OK');
                }, 
                function(error) {
                    callback(null, error);
                }, 
                geoPositionOptions 
            );  
        } else {
            callback(null, 'NOT_SUPPORTED');
        }
    }

    });

  } (jQuery) );

但您也可以按照Ved

的建议加载现有的jquery.ui.map.extensions.js

<强>此外：您还必须包含http://jquery-ui-map.googlecode.com/svn/trunk/ui/jquery.ui.map.overlays.js，这将实施addShape - 方法

演示：http://jsfiddle.net/doktormolle/rd4Xt/ 的＆LT; /编辑＆gt;

Answer 2

同时添加此javascript文件..

<script type="text/javascript" src="http://jquery-ui-map.googlecode.com/svn/trunk/ui/jquery.ui.map.extensions.js"></script>

我的googlemap地理位置不起作用
