Is it possible to retrieve the value from textbox before submission?

I have a textbox where users will input their mobile numbers.

<input type="number" name="mobileNumber" id="mobileNumber" runat="server" />

I also have a dialog box where I used it as a confirmation when the users click on the submit button.

var answer = confirm("The number you have entered is <%= confirmNumber %>.\nPlease verify if the number you have entered is correct.")

if (!answer) {
    return false;
}

My expected output is here where __________ is supposed to be the value of the textbox.
(Apparently I don't have enough points to embed pictures yet?)

What I want to do is to retrieve the value from the textbox and replace the underscores in the dialog box with it.

Here is my C# attempt to retrieve the value from the textbox:

string confirmNumber = mobileNumber.Value;

I think that the C# code can only retrieve the value after the user has submitted? I am not really sure. Please help.

You want to show value that is entered on client side in textbox you can use javascript which you already have to show value to user. You have to use the ClientID of input to get its html element in javascript.

number = document.getElementById("<%=mobileNumber.ClientID%>").value;
var answer = confirm("The number you have entered is" + number  + ".\nPlease verify if the number you have entered is correct.")
