javascript - 如何使用带有 if else 语句的提示打印值？

Question

var age = '16';
prompt(enter 'age');
if (age > 17) {
  alert("good to drive");
} else {
  alert("sorry you are not eligible");
}

Answer 1

您有一些语法错误，但这里有一个修补版本:

var age = prompt("Please enter your age"); // Gets input
if (age > 17) {
  alert("Good to drive.");
} else {
  alert("Sorry you are not eligible.");
}
