想知道continue在这里起什么作用，去掉得话应该如何改写？

Question

   var my_department = [];                    for (var i = 0; i < aggregations.all_outdept_name.buckets.length; i++) {                        if (aggregations.all_outdept_name.buckets[i].key == '') continue;                        var department_obj = {                             value: aggregations.all_outdept_name.buckets[i].key,                            label: aggregations.all_outdept_name.buckets[i].key,                             count: aggregations.all_outdept_name.buckets[i].doc_count                         }                         my_department.push(department_obj);                     }                     _this.department = my_department;

Answer 1

continue的意思是跳过这轮循环，马上开始下轮循环。 在你的代码中，执行continue，那么if语句continue之后的都不执行了。 i++后执行新的一轮循环判断。

若想去掉，你就反着写呗，即满足xxx条件才执行if continue下面的语句

for (var i = 0; i < aggregations.all_outdept_name.buckets.length; i++) {    if (!(aggregations.all_outdept_name.buckets[i].key == '')){        var department_obj = {            value: aggregations.all_outdept_name.buckets[i].key,            label: aggregations.all_outdept_name.buckets[i].key,            count: aggregations.all_outdept_name.buckets[i].doc_count
        }
        my_department.push(department_obj);
    }
}
