Question

在日志中看到jobs吗？它不是数组，如何将其作为数组推送（这样我就可以通过循环访问它了。）

var name = "John"
var age = 30
var jobs = ['a', 'b', 'c']

obj = []

obj.push('{name: "'+name+'", age: "'+age+'", jobs: '+jobs+'}')

console.log(obj) // result: ["{name: "John", age: "30", jobs: a,b,c}"]    
/////////////////// goal: ["{name: "John", age: "30", jobs: ["a","b","c"]}"]

Answer 1

使用JSON.stringify吗？

obj.push('{name: "'+name+'", age: "'+age+'", jobs: '+ JSON.stringify(jobs)+'}')

Answer 2

我认为您想做的是

obj.push({jobs:['a', 'b', 'c'], age:30, name:'John'})

Answer 3

在数组上使用映射。

var name = "John"
var age = 30
var jobs = ['a', 'b', 'c']
obj = [];
let temp = jobs.map((v) => `"${v}"`);
obj.push(`{name: ${name}, age: ${age}, jobs: [${temp.join(",")}]}`)
console.log(obj) // ["{name: "John", age: "30", jobs: a,b,c}"]

Answer 4

一种解决方案是映射数组，然后在推入obj之前更改每个项目的值。

var name = "John"
var age = 30
var jobs = ['a', 'b', 'c']
jobs = jobs.map(item => `"${item}"` );

obj = []

obj.push('{name: "'+name+'", age: "'+age+'", jobs: ['+jobs+']}')


console.log(obj)
