Question

我正在做一个学校运动，并且如此接近完成它但却无法弄清楚这一部分。不知道要看什么，要么看到它是非常具体的。我试图做的是显示四个人的年龄，一个未满18岁，这样就会显示出不同的东西，并且成功。我将展示一张图片以便更好地理解。

我想要的是阻止他们重复，并将不同的年龄分配给四个不同的人。

如果这个人想要显示它们是否超过18，则显示为true，否则显示false。但我希望他们两个同时显示。

这是代码

var iYear = [1995, 1986, 1991, 2002, 1999];
var iAges = [];
var iAdultAges = [];
var lenYear = iYear.length;
var iCurrent = 2017;
    for (var i = 0; i < lenYear; i++){
        var a = iCurrent - iYear[i];
        var iAge = iAges.push(a);
        console.log(iAges[0]);
    }
    for(x = 0; x < iAges.length; x++){               // x = 0 is a starting point
        if (iAges[x] < 18){                          // x < iAges.length is a ending point, this calculates it as 5
            iAdultAges.push(iAges[x]);               // x++ says how much we want the value to go up by.
            var YoungIndividual = iAges.indexOf(15);
            console.log("Person " + YoungIndividual + " is " + iAges[x] + " so they are NOT of age.");
        }else if (iAges[x] >= 18){
            iAdultAges.push(iAges[x]);
            console.log("Mary-Ann is " + iAges[x] + " years old and is of age.");
            console.log("Dale is " + iAges[x] + " years old and is of age.");
            console.log("Ali is " + iAges[x] + " years old and is of age.");
            console.log("Karl is " + iAges[x] + " years old and is of age.");
        }
    }
    function printAdultAge(iYear){
        var Ages = [];
        var adultAges = [];
        var booLean = ["True", "False"];
            for (var z = 0; z < lenYear; z++){
			     var b = iCurrent - iYear[z];
			     var age = Ages.push(b);
                console.log(iAges[0]);
			};
        for(e = 0; e < Ages.length; e++){               // e = 0 is a starting point
            if (Ages[e] < 18){                          // e < iAges.length is a ending point, this calculates it as 5
                iAdultAges.push(Ages[e]);               // e++ says how much we want the value to go up by.
                var YoungIndividual = Ages.indexOf(15);
                console.log("Person number " + YoungIndividual + " is " + Ages[e] + ". They are too young.");
                return booLean[1];
            }else if (Ages[e] >= 18){
                iAdultAges.push(Ages[e]);
                console.log("Mary-Ann is " + Ages[e] + ".");
                console.log("Dale is " + Ages[e] + ".");
                console.log("Ali is " + Ages[e] + ".");
                console.log("Karl is " + Ages[e] + ".");
                return booLean[0];
            }
        }
    };
console.log(printAdultAge(iYear));

除非我误解了这个问题，否则看起来你过于复杂了。给出的数据是多年的数组？你是否也给出了这些名字，或者你是否正在制作这些名字？

使用代码中给出的数据，您可以尝试更简单的方法：

var years = [1995, 1986, 1991, 2002, 1999];
var yearsLength = years.length;
var ageThreshold = 18;
var currentYear = new Date().getFullYear();

for (var i = 0; i < yearsLength; i++) {
   var personsAge = currentYear - years[i];
   var isOfAge = personsAge >= ageThreshold;
   console.log('Person ' + (i + 1) + ' is ' + personsAge + ' years old');
   console.log(isOfAge);
}

如果给出了数组中的名称，则可以使用相同的索引（i）访问它们，但似乎有4个名称和5年值，因此在尝试读取第5个时会出错。

的JavaScript。如何停止重复输出数组并添加布尔值？
