不同范围的百分比值

问题描述

我从昨天开始尝试在JavaScript中找到一个公式（也是数学公式），该公式返回3种不同情况下给定百分比的值。

var element = createElement('p');
//If addEventListener is needed
element.addEventListener('click',function(){},false);

解决方法

这是您的公式： 试试这个。

const percentage = function(x,y,perc){
    // x is start point
    // y is end point
    // so you need length of this range (between x and y) and we subtract x from y
    // and dividing to 100 (because 100% is full range between x and y)
    // when we divide it to 100,the result is 1% of the range
    // then we multiply it to percentage we want for example 25%
    // and adding x to result. Because we started from x;



    return ((y-x)/100)*perc+x;
}

console.log(percentage(0,10,25));
console.log(percentage(0,100,50));
console.log(percentage(-5,5,50));
console.log(percentage(-10,25));
console.log(percentage(-11,-1,30));
