As far as I know, there is a readline() function, but it is a specific function for spidermonkey, it isn't a part of javascript.
据我所知，有一个 readline() 函数，但它是蜘蛛猴的特定函数，它不是 javascript 的一部分。
Example:
例子：
1)readline-test.js:
1）readline-test.js：
print("Type some text and press <ENTER>:\t");
var userInput = readline();
print("User input: " + userInput);
2)js readline-test.js
2)js readline-test.js

You can't really depend on the console being there. It's not something that is guaranteed, even while most browsers do have a javascript console. Beyond that I don't believe you can get values without calling a function with the console.
你不能真的依赖那里的控制台。即使大多数浏览器确实有一个 javascript 控制台，也不能保证这一点。除此之外，我不相信您可以在不使用控制台调用函数的情况下获取值。
