Saving User Input

• Retrieve a user’s input using .value.
• Save it inside a variable.
• Display the input on a page.

Example

• Typing in an input box on a website for login or sharing content.

Steps to Store/Use User Input

1. Create a Variable:
   • Use let to declare a variable to save user input.
   • Example: let userInput;
2. Store the Input with .value:
   • Use .value to get the value from an input field.
   • Example: let userInput = document.querySelector("input").value;
3. Display on Page with .innerHTML:
   • Use .innerHTML to show the user input on the webpage.
   • Example:

     button.addEventListener("click", function() {
         let userInput = document.querySelector("input").value;
         document.querySelector("div").innerHTML = userInput;
     });

Key Questions

• Why create a variable first?
  • To store the user input for later use.
• What gets saved in userInput?
  • Whatever the user types in the input field, like "coding is fun!"

Recap: Saving User Input

• Three Steps: Create variable, store with .value, display with .innerHTML.
• Console Usage: Use console.log() to check the value stored in variables during development.
