Javascript 猫鼬&x2B；Node.js：异步问题

我的ReadyForReview收藏中有一堆个人资料。每个配置文件都包含一个“用户id到审查”字段。我想使用user_id_to_review将用户集合中的用户信息附加到每个配置文件中

// looking for all ReadyForReview profiles
ReadyForReview.find()
.exec(function(err, profilesReadyForReview) {
    var profilesReadyForReviewArray = [] //array that will be populated with profiles and user info

    // for each profile, figure out what the info for the user is from user table
    for (var i = 0; i < profilesReadyForReview.length; i++) {
        var thisUserProfile = profilesReadyForReview[i].user_id_to_review.toObjectId() // create objectID version of user_id_to_review
        User.find({
                '_id': thisUserProfile
            })
            .exec(function(err, user_whose_profile_it_is) {
                profilesReadyForReviewArray.push({
                    profile: profilesReadyForReview[i],
                    user: user_whose_profile_it_is
                })
            })
        console.dir(profilesReadyforReviewArray) // should be an array of profiles and user info
    }

})

//查找所有ReadyForReview配置文件
ReadyForReview.find（）文件
.exec（函数（err、profilesReadyForReview）{
var profilesReadyForReviewArray=[]//将填充配置文件和用户信息的数组
//对于每个配置文件，从用户表中找出用户的信息
对于（变量i=0；i

但是，由于异步，User.find函数中的i是错误的。如何获得一系列配置文件和用户信息？

使用异步库进行循环。

我认为你在这里是正确的，但是提到

档案repadyforreview[I]

可能只是

档案

起作用了！谢谢你们两位！愿密码之神在你的日子里光芒四射。

    var profilesReadyForReviewArray = [] //array that will be populated with profiles and user info

    // for each profile, figure out what the info for the user is from user table
    async.each(profilesprofilesReadyForReview, function(profile, done) {
        var profileId = profile.user_id_to_review.toObjectId() // create objectID version of user_id_to_review
        User.find({
                '_id': profileId
            })

                    profile: profile,
                    user: user_whose_profile_it_is
                })
