爲什麼在IE中嘗試/抓住javascript失敗

Question

Try 
{ 
myTextTrack = myPlayer.addTextTrack('subtitles','myLabel','en'); 
    } catch(err) 
{ 
alert('This browser does not support the comments on the video.'); 
return; 
    } 

以上應該會觸發IE中的警報（不在Chrome中）。但它會給腳本語法錯誤。代碼由asp.net生成，然後插入，所以在每行之後都有回車/換行符。但那不應該。

Answer 1

如果可以，請嘗試更改大寫字母T.

Answer 2

JavaScript區分大小寫。 try應該是小寫字母

try 
{ 
myTextTrack = myPlayer.addTextTrack('subtitles','myLabel','en'); 
    } catch(err) 
{ 
alert('This browser does not support the comments on the video.'); 
return; 
    }
