将返回的 object 推送到对象数组中

Question

我正在尝试将 function setData （一个对象）的 output 保存到一个数组（ state=[] ），但不知道如何。 这是代码：

const sbmt = document.getElementById("myForm");
const elName = document.getElementById("iname");
const elGender = document.getElementById("igender");
const elAge = document.getElementById("iage");
const elForm = document.getElementById("myForm");

const setData = (event) => {
    event.preventDefault();

    let nodeList = document.forms[0].elements;
    let flatNodeList = [...nodeList].map(x => x.value).filter(x => x !== "Submit");

    let objData = {
        userName: flatNodeList[0],
        userGender: flatNodeList[1],
        userAge: flatNodeList[2]
    };

    console.log(objData);

    return objData;
};

let state =[];

const resetForm = () => elForm.reset();

sbmt.addEventListener("submit", setData);
sbmt.addEventListener("submit", resetForm);

您基本上只需要将数据推送到您的state阵列中。 退回 object 不会有任何影响。

let state =[];

const setData = (event) => {
    event.preventDefault();

    let nodeList = document.forms[0].elements;
    let flatNodeList = [...nodeList].map(x => x.value).filter(x => x !== "Submit");

    let objData = {
        userName: flatNodeList[0],
        userGender: flatNodeList[1],
        userAge: flatNodeList[2]
    };

    console.log(objData);

    state.push(objData);
};
