推荐答案

您可以使用Array#forEach完成此操作……但是您的数组元素将被字符串化.

You can use Array#forEach to accomplish this... however your array elements will be stringified obejcts.

const dependents = [{name: "ashraf", number: 96546},{name: "himanshu", number: 98766}]
const data = new FormData();
dependents.forEach(item => {
  data.append(`dependents[]`, JSON.stringify(item));
});
console.log(data.getAll('dependents[]'));
