javascript如果数字可以被整除，则为true；否则为true

Question

I have to write Java script that can read two integers from the user, if the first number the user entered is evenly divisible by the second number, then it will display an alert of TRUE to the user, and FALSE otherwise. If either number the user enters is ZERO the alert should display FALSE to the user.

this is my code it does not work

        var y = prompt("Enter a Value","");
      var z = prompt("Enter a Value","");

      if  (y % z === 0) {
      greeting = "TRUE";
      } else (y % z !== 0 ||
      {
      greeting = "FALSE"
      document. get Element By Id ("true false").inner HTML = greeting;

Answer 1

If either number the user enters is ZERO the alert should display FALSE to the user.

change you if condition to

if  (x && y && y % z === 0) {

Rest of the code is

if  (x && y && y % z === 0) 
{
   greeting = "TRUE";
}
else
{
   greeting = "FALSE";
}

Answer 2

如果您不熟悉javascript，这里是使用三元运算符实现此非常常见模式的另一种方法：

var greeting = (x && y && y % z === 0) ? "TRUE" : "FALSE";
