Internet ExplorerのActiveXコントロールでJavaScriptメソッドを呼び出すときに不一致が発生する

Question

私は、MATLABとGoogle Earthプラグインのインターフェイスを取っています。このプラグインはJavaScriptを使用するため、Internet ExplorerのActiveXコントロールをGoogle Earthプラグインのホストとして使用します。

下記の簡単なデモ（testJS.html）では、事前定義された座標を使用してGoogle Earthでまっすぐな動きを模倣しました。 （FirefoxとIEのみで動作しますが、IEでは速度が少し速いですが）。

同じ座標を使用して、私はMATLABスクリプトからJavaScriptメソッドを呼び出しました。まっすぐな動きではなく、ジグザグの動きです。最初は、Google Earthは小数点以下6桁までサポートしていたので、問題は入力の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の小数点以下の桁であるしかし、小数点以下の桁数を減らすことは喜びをもたらしませんでした。

何が間違っているのでしょうか？

ありがとうございました。

ワン。

Answer 1

主にイベントリスナーの数とtickAnimation（）の呼び出しの数がいくつかあります。

62個のイベントリスナーを作成していますが、そのすべてがフレームが再描画されるたびに呼び出されています。私たちが知る必要があるのはアニメーションを更新する時期なので、複数のイベントリスナーを持つ必要はありません。

また、tickAnimation関数がどのように構造化されているかは、毎回呼び出されるさまざまな座標配列を再作成すると、実際には効率が悪いです。

最後に、イベントリスナーを追加するときは、デリゲートメソッドへの参照を渡すだけです（または匿名関数を使用する必要があります）。実際にはtimertickメソッドが呼び出されます。例えば

google.earth.addEventListener(ge,'frameend',tickAnimation(i)); 

google.earth.addEventListener(ge,'frameend', tickAnimation); 

または

google.earth.addEventListener(ge,'frameend', function() { //something }); 

とにかく、私はこれらの問題をクリーンアップし、コードを片付け、私のためAOKを動作するようです...

する必要があります
