在收到有效输入之前,如何继续使用JavaScript if？else if语句？

Question

如何使用if ... else if语句继续提示用户提供有效响应？我的脚本目前只运行一次,但随后中断:

var enterNum = prompt("Please enter a number between 1 and 100", "");


if (isNaN(enterNum)){
    enterNum = prompt("You did not enter a valid number. Please try again", "")
}
else if (enterNum < 1 || enterNum >100){
    enterNum = prompt("Your number is not between 1 and 100. Please try again", "")
}
else{
    document.write("Your number is ", enterNum)
}

提前致谢!

var enterNum = prompt("Please enter a number between 1 and 100", "");

while(isNaN(enterNum) || enterNum < 1 || enterNum >100) {
    enterNum = prompt("You did not enter a valid number. Please try again", "")
}
document.write("Your number is ", enterNum)
