Question

这是有问题的for循环：

console.log(sender1[0]); // returns user object
console.log(sender1.length); // returns 1
for (var i = 0; i < sender1.length; i = i + 1) {
    console.log(sender1[i].phone); // returns can't read phone property of undefined
}

这是我收件人1的地方

User.find().where({
    code: req.body.Body.toUpperCase()
}).exec(function (err, sender1) {

这是使用mongoose，所以sender1已经是一个数组。我尝试使用.toArray，它说find没有方法“toArray”。

如果我用发件人[0]替换所有发件人[i]，一切正常。但是它说发件人[i] .somename是未定义的。我的循环出了什么问题？

以下是未格式化的完整代码，希望有人看到破坏循环的细微差别：

User.find().where({
    code: req.body.Body.toUpperCase()
}).exec(function (err, sender1) {
    // Who sent the message?

    console.log('this is sender1 length ', sender1.length);

    for (var jj = 0; jj < sender1.length; jj = jj+1) {
        console.log('The for loop executed!');
    console.log('this is sender1 section', sender1[jj].section);
    console.log('jj is', jj);
        User.findOne({
            phone: req.body.From,
            section: sender1[jj].section
        }, function (err, from1) {
          console.log('This is the from1 phone',from1.phone);
          console.log('This is the section1 phone',sender1[jj].phone);

我的for循环打破了我的代码
