如何使用JavaScript在对象数组中添加对象

Question

I have the below JS object and I need to push another similar object with request.rules[0] .

request :  [
  rules: 
  [
    {
      pageFilters: 
      [
        {
          matchType: 'contains', 
          type: 1, 
          value: 'a'
        }, 
        {
          matchType: 'does not contain', 
          type: 1, 
          value: 'b'
        }
      ], 
      name: 'TEST'
    }
  ]
]

This is the object that I need to push to request.rules[1]:

{
  pageFilters: 
  [
    {
      matchType: 'contains', 
      type: 1, 
      value: 'c'
    }, 
    {
      matchType: 'does not contain', 
      type: 1, 
      value: 'd'
    }
  ], 
  name: 'TEST 2'
}

This is what I've tried to implement, but it does not work ...

request.rules[1].pageFilters[0].push({
  matchType: 'contains', 
  type: 1, 
  value: 'c'
})
request.rules[1].pageFilters[1].push({
  matchType: 'contains', 
  type: 1, 
  value: 'd'
})
request.rules[1].name = "TEST 2";

This is the expected result:

request :[
  rules: 
  [
    {
      pageFilters: 
      [
        {
          matchType: 'contains', 
          type: 1, 
          value: 'a'
        }, 
        {
          matchType: 'does not contain', 
          type: 1, 
          value: 'b'
        }
      ], 
      name: 'TEST'
    },
    {
      pageFilters: 
      [
        {
          matchType: 'contains', 
          type: 1, 
          value: 'c'
        }, 
        {
          matchType: 'does not contain', 
          type: 1, 
          value: 'd'
        }
      ], 
      name: 'TEST 2'
    }
  ]
]

Answer 1

You do not have to push to a specific position eg request.rules[1].pageFilters[0], but rather to the array itself like this

var anotherFilter = {
  matchType=contains, 
  type=1, 
  value=c
};

request.rules[1].pageFilters.push(anotherFilter);

Answer 2

With a proper object with request as object,

request: { // should be an object, not an array
    rules: [

you could just use

 var object1 = { request: { rules: [{ pageFilters: [{ matchType: 'contains', type: 1, value: 'a' }, { matchType: 'does not contain', type: 1, value: 'b' }], name: 'TEST' }] } }, object2 = { pageFilters: [{ matchType: 'contains', type: 1, value: 'c' }, { matchType: 'does not contain', type: 1, value: 'd' }], name: 'TEST 2' }; object1.request.rules.push(object2); console.log(object1); 

 .as-console-wrapper { max-height: 100% !important; top: 0; }

我了解您的代码，{matchType = contains，type = 1，value = c}我见过{type：1，value：c}
