调整应用程序的画布大小

问题描述：

我们一直在努力为canvas应用程序设置高度，而不用运气。

we have been trying to setup the height for a canvas app without luck.

这是我们使用的代码

window.fbAsyncInit = function()
{
// assume we are already logged in
FB.init({appId: '<?=$fb_app_id ?>', xfbml: true, oauth : true,cookie: true});
FB.Canvas.setAutoGrow();
}
function sizeChangeCallback() {
FB.Canvas.setSize({ width: 810, height: 950);
}

我们尝试过没有sizechangecallback

We tried both without the sizechangecallback

，我们的设置设置为固定和固定950

and our settings set to Fixed and Fixed 950

答

在应用程序设置中设置固定高度参数后，

您可以调用 FB.Canvas.setSize 来更改页面高度。

After you setup the fixed height parameter in your application settings,
you can call FB.Canvas.setSize to change the page height.

如果您的页面高度动态变化，则可以运行 FB.Canvas.setDoneLoading

来检查Canvas是否已加载并运行 FB .Canvas.setAutoGrow 。

If your page height changes dynamically, you can run FB.Canvas.setDoneLoading
to check if Canvas is loaded and run FB.Canvas.setAutoGrow.

window.fbAsyncInit = function() {
    // assume we are already logged in
    FB.init({ appId: '<?=$fb_app_id ?>', xfbml: true, oauth: true, cookie: true });

    FB.Canvas.setSize({ width: 810, height: 950 });

    FB.Canvas.setDoneLoading( function(response) {
        console.log(response.time_delta_ms);
        FB.Canvas.setAutoGrow();
    });
}
