如何从 javascript 检查 Flash 对象是否处于全屏模式

发布于 2024-12-10 11:48:47 字数 182 浏览 0 评论 0原文

我需要从 JavaScript 检查给定的 Flash 对象是否处于全屏模式。我知道有 stage.displayState 属性，但如何使用 GetVariable 访问它？或者也许还有另一种方法？

谢谢。

PS 如果你知道如何用其他语言做到这一点，那也没关系。

您可能需要在 AS 内添加一个可以从 JS 层调用的函数：

// In your AS code
import flash.external.ExternalInterface;
import flash.display.StageDisplayState;

// Register a function you can call from JS
ExternalInterface.addCallback("isFullScreen", _isFullScreen);

// Returns true if fullscreen
private function _isFullScreen() :Boolean {
    return stage.displayState === StageDisplayState.FULL_SCREEN:
};

然后，您应该能够从 JS 调用它：

// Get a reference to the object element, change
// 'flashcontent' to the ID of your .swf in the DOM
var o = document.getElementById('flashcontent'),
    // Figure out it the player is in fullscreen mode
    isFullScreen = o.isFullScreen();
// Do something with isFullScreen value

ExternalInterface 文档此处，舞台显示状态此处。

希望有帮助。干杯！

you'll probably need to add a function inside AS that you can call from the JS layer:

// In your AS code
import flash.external.ExternalInterface;
import flash.display.StageDisplayState;

// Register a function you can call from JS
ExternalInterface.addCallback("isFullScreen", _isFullScreen);

// Returns true if fullscreen
private function _isFullScreen() :Boolean {
    return stage.displayState === StageDisplayState.FULL_SCREEN:
};

then, you should be able to call it from JS:

// Get a reference to the object element, change
// 'flashcontent' to the ID of your .swf in the DOM
var o = document.getElementById('flashcontent'),
    // Figure out it the player is in fullscreen mode
    isFullScreen = o.isFullScreen();
// Do something with isFullScreen value

docs for ExternalInterface here, stage display state here.

hope that helps. cheers!
