是否有拋出異常的其他語句？

Question

我是JavaScript新手，但對編程/腳本一般來說並不陌生，而且我有關於throw例外的查詢。

所以，我想知道的是有聲明throw例外。

E.g

// More code above 
try 
{ 
    if(i=="something") { 
     throw "'i' equals 'something'." 
    } 
    else 
    { 
     throw "'i' doesn't equal 'something'." 
    } 
} 
// More code here 

是類似的東西可能嗎？

您可能正在尋找finally關鍵字

try 
{ 
    if(i=="something") { 
     throw "'i' equals 'something'." 
    } 
    else 
    { 
     throw "'i' doesn't equal 'something'." 
    } 
} catch(ex) { 
    // your exception handling code 
} finally { 
    // Statements that are executed after the try statement completes. 
}
