不要在循环中创建函数

Question

在这种情况下解决jslint错误的正确方法是什么？我正在为使用它的对象添加一个getter函数.如果不在循环内创建函数,我不知道如何做到这一点.

for (var i = 0; i<processorList.length; ++i) {
   result[i] = {
       processor_: timestampsToDateTime(processorList[i]),
       name_: processorList[i].processorName,
       getLabel: function() { // TODO solve function in loop.
            return this.name_;
       }
   };
}

Answer 1

将函数移到循环外:

function dummy() {
    return this.name_;
}
// Or: var dummy = function() {return this.name;};
for (var i = 0; i<processorList.length; ++i) {
   result[i] = {
       processor_: timestampsToDateTime(processorList[i]),
       name_: processorList[i].processorName,
       getLabel: dummy
   };
}

...或者只是使用文件顶部的loopfunc选项忽略该消息:

/*jshint loopfunc:true */
