javascript - 如何转换我的这个 js 代码，以便通过输入值和单选按钮值更新对象的每个属性？

Question

我有一个object具有 3 个属性(amount,date,type)的对象。每次调用该对象时，日期都会自动更新。这是代码

var Transaction = function(amount, type) {
    this.amount = amount;
    this.type = type;
    this.date = (function() {
        var d = new Date();
        var minutes = d.getMinutes();
        var month = d.getMonth() +1;
        if (minutes<10) {
            return (d.getDate() + "/" + month + "/" + d.getFullYear() + " " + d.getHours() + ":" + "0" + minutes);
        } else {
            return (d.getDate() + "/" + month + "/" + d.getFullYear() + " " + d.getHours() + ":" + minutes);
        }
    })();

如何设置它以便amount可以接收 html 输入字段type的值和单选按钮的值？我想用纯JS

Answer 1

如果传递了输入字段，它将采用它的值，否则只需使用传递的值

this.amount = amount.value || amount;
this.type = type.value || type;
