We can breakboth a $(selector).each()loop and a $.each()loop at a particular iteration by making the callback function return false. Returning non-falseis the same as a continue statement in a forloop; it will skip immediately to the next iteration.
我们可以打破既有$(selector).each()环和一个$.each()通过使回调函数返回在一个特定的迭代循环false。返回non-false与for循环中的 continue 语句相同；它将立即跳到下一次迭代。
return false; // this is equivalent of 'break' for jQuery loop
return; // this is equivalent of 'continue' for jQuery loop
Note that $(selector).each()and $.each()are differentfunctions.
请注意，$(selector).each()和$.each()是不同的功能。

$('.submit').filter(':checked').each(function() {
//This is same as 'continue'
if(something){
return true;
}
//This is same as 'break'
if(something){
return false;
}
});

我们可以通过使回调函数返回 false 来在特定迭代中中断 $.each() 循环。返回非 false 与 for 循环中的 continue 语句相同；它将立即跳到下一次迭代。-- jQuery.each() | jQuery API 文档

return or return false are not the same as continue. If the loop is inside a function the remainder of the function will not execute as you would expect with a true "continue".
return 或 return false 与 continue 不同。如果循环在函数内部，则函数的其余部分将不会像您期望的那样执行真正的“继续”。
