是否有抛出异常的其他语句？

Question

我是JavaScript新手，但对编程/脚本一般来说并不陌生，而且我有关于throw例外的查询。

所以，我想知道的是有声明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 

是类似的东西可能吗？

您可能正在寻找finally关键字

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. 
}
