如何break/exit jquery.each()方法

在使用jQuery的each()方法时,如何跳出循环呢?根据官方文档的说明,可以使用return false进行break,如下:

We can break the $.each() loop at a particular iteration by making the callback 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.

示例:

function checkIsSearchForNothing() {
    var result = false;
    $("#searchForm").find("input[type='text']").each(function () {
        if ($(this).val() != null && $(this).val() != '') {
            result = true;
            return false;
        }
    });
    return result;
}
