喜欢这个：

var a = [
    {type: 'text', name: 'title', id: 'title', placeholder: 'Type here'},
    {type: 'textarea', name: 'description', id: 'description', placeholder: 'Type here'}
]

var b= {type: 'text', name: 'age', id: 'age', placeholder: 'Type here'} 

a.splice(1,0,b);

console.log(a)

If your array is in variable array , then:

array.splice(1, 0, {
    type: 'text',
    name: 'age',
    id: 'age',
    placeholder: 'Type here'
});

The 1 means that you want to place it at index 1 , 0 means you want to delete 0 items from the array. See splice documentation, it is quite the abomination of a method with 2 purposes of which both are never used at the same time :D

如果您想在该确切位置使用该对象，请使用splice方法。

var myArray = [{
  type: 'text',
  name: 'title',
  id: 'title',
  placeholder: 'Type here'
}, {
  type: 'textarea',
  name: 'description',
  id: 'description',
  placeholder: 'Type here'
}];
var myObject = {
  type: 'text',
  name: 'age',
  id: 'age',
  placeholder: 'Type here'
};
myArray.push(myObject);
