Question

I want to have a text field where user can type in some text and I want to store whatever they typed in a javascript variable? How do I do this?

Answer 1

var userText = document.getElementById("yourTextInputId").value;

That will store the value of the element with id of “yourTextInputId” in the variable userText. You could put this in a function and call it whenever you need to store the value (for example, when a button is clicked, or when the blur event is fired).

Here’s an example binding a blur event to the text input field:

document.getElementById("yourTextInputId").onblur = function() { 
    var userText = this.value;
}
