为什么我的数组返回的是对象而不是数字？
[英]Why my arrays are returning object instead of numbers?
问题描述
I am trying to find Least Common Multiple.
我正在尝试找到最小公倍数。 But when I tried to find the final result, I got NaN and realized both of my arrays are returning object.但是当我试图找到最终结果时，我得到了NaN并意识到我的两个数组都在返回对象。 Sharing the code below -分享下面的代码 -
function myFunction(){
//For x
var x = document.getElementById("int").value;
let textx = "";
let multiplex = [];
//For y
var y = document.getElementById("int1").value;
let texty = "";
let multipley = [];
//result
let result = "";
//FINDING THE MUTIPLES OF X
if(isNaN(x)==false){
for (let i = 1; i < 11; i++) {
if (i === 11) { break; }
multiplex.push(((i*x)).toFixed(2));
}
textx += multiplex + " are the multiples of "+x;
}else{
window.alert("Please input a number. "+x+" is not a number")
}
document.getElementById("demo").innerHTML = textx;
//FINDING THE MULTIPLES OF Y
if(isNaN(y)==false){
for (let i = 1; i < 11; i++) {
if (i === 11) { break; }
multipley.push(((i*y)).toFixed(2));
}
texty += multipley + " are the multiples of "+y;
}else{
window.alert("Please input a number. "+y+" is not a number")
}
document.getElementById("demo1").innerHTML = texty;
//Finding intersection and LCD
const filtArray = multiplex.filter(value => multipley.includes(value));
console.log(Math.min(filtArray))
//Testing typeof
console.group(typeof multiplex) //result object
console.group(typeof multipley) //result object
//result += Math.min(filtArray) + "is the Least Common Multiple (LCM)"
//document.getElementById('result').innerHTML = result;
}

Use "Math.min(...filtArray);"使用“Math.min(...filtArray);” instead.反而。 We use the spread operator ... when calling the Math.min method.我们在调用 Math.min 方法时使用扩展运算符 ...。
Since the Math.min method expects comma separated numbers as arguments, we can't directly pass it an array.由于 Math.min 方法需要以逗号分隔的数字作为参数，因此我们不能直接将其传递给数组。
This works like a charm这就像一个魅力
