eval與try/catch的投擲錯誤

我有一個空氣應用程序，其中用戶在textarea中鍵入javascript，並且它在mx：HTML組件中被評估，但即使使用圍繞eval的try/catch，圍繞eval中的代碼和HTMLUncaughtScriptExceptionEvent處理程序，它仍會引發錯誤。 htmlWindow是html.htmlLoader.window。eval與try/catch的投擲錯誤

try { htmlWindow.eval("try {" + script.text + "} catch (error:Error) { trace(error) }); } catch (error:Error) { trace(error) }

，只要我在script輸入文本在該行的應用程序錯誤，與

任何方式來阻止錯誤？我試過script.change="html.htmlText = '<script>' + script.text + '</script'>"，但我有htmlWindow.log = log; htmlWindow.rotateSprite = rotateSprite;，如果我在修改之前複製粘貼log('test')，它會起作用，如果我在之前或之後對其進行更改，它將無法再工作，所以我希望能夠獲得此評估工作。

我不確定你可以得到這段代碼是100％例外免費。用戶可以編寫完全無效的代碼，如zlçrza ;à"çé°$，它不會拋出異常，而只是崩潰了JS編譯器。你能解釋爲什麼你讓用戶直接鍵入JavaScript代碼嗎？也許你需要以其他方式解決這個問題？
