Javascript中Python的input（）等效项是什么？

Question

I have looked for this, but haven't found anything similar. In Javascript, I want to know if there is a way to get user input, from say a text area, in the middle of a loop, such as with the input() function from python. Here is an example:

 def thing():
    color = input("Pick Red, Yellow or Blue")
    finished = False
    previous = []
    while finished == False:
        if previous == []:
            guess = "red"
            response = input("Is your color red?")
            previous.append((guess, response))
        elif len(previous) == 1:
            response = input("is your color blue?")
            if response == "yes":
                finished = True

This example is not exactly what I am trying to do but basically, I want a way, for a user to be asked things, and for them to put an answer in a text area(HTML), and push a button, which continues a Javascript while loop with the newly received input, and formulates some other question, and so on, until some condition is reached to stop the loop.

Is this possible? Does something in JS mimic this?

Good old readline();

If you want to get value from text area then use :

<script>
function myFunction() {
    var x = document.getElementById("myTextarea").value;
}
</script>
