大家好，

我是学生，正在开发自己的应用程序，以了解如何使用Google map API v3.
我在Windows Phone 7的应用程序中调用了一个名为"Up_pan"的Java脚本函数.

Hi everyone,

I am student and working my own application for knowing how to use Google map API v3.
and i call a Java script function named "Up_pan" from my application on Window phone 7.

function Up_pan() {

    var center = map.getCenter();
    var New_center = { lat: center.lat() + 1,
        lng: center.lng() + 1
    };
    map.panTo(New_center);
}

但它没有用.

推荐答案

这是我的解决方案.

This is my solution.

function up() {
         var center = map.getCenter();
        var New_center = new google.maps.LatLng(center.lat() + 0.001, center.lng() );
        map.setCenter(New_center);
}

谢谢您的阅读，希望对您有所帮助.

Thx for reading and i hope it will help someone.

我相信它应该看起来像这样:

I believe it should look like this:

function Up_pan() {
  var center = map.getCenter();
  var New_center = new google.maps.LatLng(center.lat() + 1, center.lng() + 1);
  map.panTo(New_center);
}

原因是因为您没有为panTo指定正确的类型.请注意，您的代码使中心在对角线上偏移.

The reason for this is because you weren''t specifiying the right type for panTo. Note that your code is offsetting the center in a diagonal line.

非常感谢.
您的回答对我很有帮助.

Thank a lot.
