javascript变量数大于多少？

Question

我有这个javascript函数来验证一个数字是否大于另一个数字，但我想知道我想知道的是多少。那么24是> 10但我想知道多少14。

if(ranNum > numbered){
            alert("ranNum is greater than your number");
          }else if(ranNum < numbered){
            alert("ranNum is less then your number");
          }else if(ranNum === numbered){
            alert("match");
          }else{
            alert("try again");
          }

Answer 1

通过减去两个数字并将其添加到警报来创建diff变量。

Var diff = Math.abs (ranNum - numbered);
if(ranNum > numbered) {
    alert("ranNum is greater than your number by: " + diff);
}
else if(ranNum < numbered) {
     alert("ranNum is less then your number by: " + diff);
 }
else if(ranNum === numbered) {
    alert("match");
}
else{
    alert("try again");
}
