Question

所以我正在做一个粗俗的项目。我一直在跟着，然后我必须将一个对象返回到控制台以测试某些东西，唯一的问题是，它没有返回该对象，它只是返回了该对象所在的代码部分，包括诸如注释之类的东西。这是代码：

var UIController = (function() {
var DOMstrings = {
    inputType: '.add__type',
    inputDescription: '.add__description',
    inputValue: '.add__value',
    inputBtn: '.add__btn',
    incomeContainer: '.income__list',
    expensesContainer: '.expenses__list',
    budgetLabel: '.budget__value',
    incomeLabel: '.budget__income--value',
    expensesLabel: '.budget__expenses--value',
    percentageLabel: '.budget__expenses--percentage',
    container: '.container',
    expensesPercLabel: '.item__percentage',
    dateLabel: '.budget__title--month'
};

return {
    getinput: function() { 
       var items = {
            type: document.querySelector(DOMstrings.inputType).nodeValue, 
            description: document.querySelector(DOMstrings.inputDescription).nodeValue,
            value: document.querySelector(DOMstrings.inputValue).nodeValue
        }
       return items;
    }
    }
}


)();

   // Global App Controller

    var controller = (function(budgetCtrl, UICtrl) {

var ctrlAddItem = function() { 
    // 1. Get the filled input data
    var input = UICtrl.getinput;
    console.log(input);


    // 2. Add the item to the budget controller

    // 3. Add the new item to the user interface

    // 4. Calculate the budget

    // 5. Display the budget on the UI

}


document.querySelector('.add__btn').addEventListener('click', ctrlAddItem);

// Make the ENTER key do what the CLICK does
document.addEventListener('keypress', function(event) {

    if (event.keyCode === 13 || event.which === 13) {

        console.log('ENTER was pressed');

        ctrlAddItem();
    }



} );



})(budgetController, UIController);

这是输出：

ƒ () { 
       var items = {
            type: document.querySelector(DOMstrings.inputType).nodeValue, 
            description: document.querySelector(DOMstrings.inputDescription).nodeV…

先谢谢您

Answer 1

将var input = UICtrl.getinput;更改为var input = UICtrl.getinput();

JavaScript不会返回对象，它只会返回代码段
