嗨，我使用Java for循环插入MongoDB [英] Hi, Im using Java for loop to insert in MongoDB

问题描述

我在mongodb中使用javascript for循环，但我收到多个语法错误或意外的令牌错误，我我是这两种语言的新手，所以我无法找出错误的原因，请你帮我查看下面的代码，让我知道我哪里出错



for（i = 0; i< = 3; i ++）{cars = [BMW; 梅赛德斯; 奥迪]; db.test_coll.insert（car_name：cars [i]）}

I am using a javascript for loop in mongodb but i am getting multiple syntax errors or unexpected token errors, i am new to both the languages so i am not able to pinpoint the cause of the error, can you please help me by reviewing the below piece of code and letting me know where i went wrong

for(i=0; i<=3; i++) { cars = ["BMW"; "Mercedes"; "Audi"]; db.test_coll.insert("car_name": cars[i])}

推荐答案

javascript中的数组用逗号分隔： http://www.w3schools.com/js/js_arrays.asp [ ^ ]

Arrays in javascript are separated by commas : http://www.w3schools.com/js/js_arrays.asp[^]
