jquery每次早退

Question

我在数组上有一个 jQuery for-each 循环，想知道是否可以提前离开循环。

$(lines).each(function(i){  
    // some code  
    if(condition){  
        // I need something like break;  
    }  
});

break; 实际上不起作用，这是有原因的。

如果我写一个 for 循环，它看起来像这样(但我不想要那样):

for(i=0; i < lines.length; i++){  
    // some code  
    if(condition){  
        break; // leave the loop 
    }  
};

根据docs :

If you wish to break the each() loop at a particular iteration you can do so by making your function return false. Returning non-false is the same as a continue statement in a for loop, it will skip immediately to the next iteration.
