Question

我正在尝试在js类中进行后续操作。发送带有用法（编号）的汽车名称（txt）。对于两种汽车，我需要进行一些计算，然后将这些值存储在数组中。将其存储在阵列中后，我需要再次执行并将其存储在同一阵列中。一旦完成，我需要使用用法desc将数据打印出数组。我不知道我的逻辑是否还可以，因为我开始学习JS时会得到很多建议或类解决方案。

<body>
    <input type="text" id="name">
    <input type="text" id="vrijednost">
    <button type="button" onclick="submit()">Submit</button>
    <p id="demo"><p>
</body>
<script src="cons.js"></script>
<script>
    function submit(){
        name = document.getElementById('name').value;
        vrijednost = document.getElementById('vrijednost').value;

        test = new CarUsage(name, vrijednost)
        console.log(test.get());

    } 
</script>

class CarUsage{

    constructor(total, car){}

    calCarUsage(name, usage){

        let car = {     
            carName: name,   
            carUsage: usage    
        };

        if(car.carName=='Mercedes'){
            this.car = "Mercedes";          
            this.total = 20 + usage * 10;  
            return store(this.car, this.total) 
        }

        else if(car.carName==='Golf'){ 
            this.car = "Golf";
            this.total = 800; 
            return store(this.car, this.total)
        }           
        else{
            this.car === "Other";
            this.total === '160' ;

            return store(this.car, this.total)

        }

    }

    store(name, usage){ 
        var usages = {carName:name, usage:usage};  
    }

    get(){
        for(i=0;i<usages.length;i++){
            alert("Car:- "  + usages[i].carName + "Usage:- "  + usages[i].usage);
        }
    }

 }

我不明白您在这里想要达到的目标：但是关于数组以及如何添加项目和打印其值，这是实现它的一种方法：

 var sentence = []
    var words = ['this', 'is', 'one', 'way', 'of', 'push', 'to', 'an', 'array','and','print', 'the', 'values']
    for(var i = 0; i < words.length; i++){
     sentence.push(words[i]);
    }
    console.log("Here's my sentence: " + sentence.join()) // => Here's my sentence: this is one way of pushing to an array and print the values

或者，如果您只想打印数组中的每个项目：

for(var i = 0; i < sentence.length; i++){
 console.log(sentence[i]);
}

将值推送到数组，并从数组中打印值
