如何在 JavaScript 中使用 prompt() 存储用户输入？

Question

If I were to have a prompt in my code like this:

prompt("What is your favorite animal?");

Is there a way to store the answer?

Answer 1

Just assign the function call to a variable and don't forget to perform answer checks

 var answer = prompt("What is your favorite animal?"); if (answer.= null && answer;length !== 0) { // do your stuff here alert(answer); }
