我正在尝试使用输入字段的值在对象数组中查找时间

Question

我会尽力解释这一点。我有一个输入字段，允许用户输入某个时间。我也有许多与他们共度时光的景点。一旦用户输入一个时间并单击一个按钮，该时间的所有arrtactions都应该加载到dom。事件监听器正在工作，但每个景点都在打印，即使是没有时间的景点。以下是我到目前为止所拥有的。我相信我只是遗漏了一些小细节。

<input id="timeInput" type="text" placeholder="Ex: 1:00 PM">
    <button id="timeBtn">Show me Scheduled Events!</button>



let timeTest = [];
let timesArray = [];
let timeSearch = document.getElementById("timeInput");
$('#timeBtn').on('click',((e) => {
timeTest.push(timeSearch.value);
let timeSplit = timeTest[1].split(":");
let hourSelected = timeSplit[0];
let morningOrEvening = timeSplit[1];
controller.getType()
.then((data) => {
    for(let i = 0; i < data.length; i++) { 
        if (data[i].times !== undefined) {
            if (timeValueCheck(data[i].times)) {
                timesArray.push(data[i]);
            }
        else {
            timesArray.push(data[i]);
        }
    }}
    timesArray.forEach(attraction =>{
        $('#output').append(attrHBS(attraction));
        console.log(attraction);
        }
     );
    }
);
}));


let timeValueCheck= (timesArray) => {
    let timeSplit = timeTest[1].split(":");
    let hourSelected = timeSplit[0];
    let morningOrEvening = timeSplit[1];
    for (let i=0; i < timesArray.length; i++) {
        let splitArray = timesArray[i].split(":");
        console.log("super", splitArray);
        if (hourSelected === splitArray[0]){
            console.log("mega",hourSelected, splitArray[0]);
            return true;
        }
    }

    return false;
};


// this is what is inside controller.js

module.exports.getType = (attrData) => {
//creating new Promise to load when used in other functions
return new Promise((resolve, reject) => {
//getting our data from two ajax calls, attractions and attraction types
let p1 = factory.getAttractionData();
let p2 = factory.getAttTypes();
// empty array to push data into once we have manipulated it
let newDataWithTypes = [];
//promise all to get both data types before using them.
    Promise.all([p1,p2])
    .then((attrData) => { 
        // loop over the first array, all 132 attractions
        attrData[0].forEach(allAttractions => {
            // loop over second array, the 8 types
            attrData[1].forEach(typeofAttractions => {
                // if statement to add the types to each attraction based on their type id!
                    if (allAttractions.type_id === typeofAttractions.id) {
                        allAttractions.type = typeofAttractions.name;
                        // pushes to the array on 32
                        newDataWithTypes.push(allAttractions); 
                    }
                });
            });
            resolve(newDataWithTypes);
        }
    );
});
};

Answer 1

javascript中数组的索引以0开头。我认为这是问题所在。 试试这个

let timeSplit = timeTest[0].split(":");...

而不是

let timeSplit = timeTest[1].split(":");...

Answer 2

这行不应该是'0'吗：

let timeSplit = timeTest[0].split(":")
