Input Hints

Functionality:

• Generates a list of hints based on user input.
• Displays matching hints as the user types.
• Allows users to select a hint and populate the input field.

Usage: you import like this

const inputHints = acode.require('inputHints');

then

const inputHints = acode.require('inputHints');

const $input = document.getElementById("myInput");
const hints = ["apple", "banana", "cherry"]; // Array of hint strings

const handleSelect = (value) => {
  console.log("Selected hint:", value);
};

const hintsComponent = inputhints($input, hints, handleSelect);

console.log("Selected hint element:", hintsComponent.getSelected());
console.log("Hint list container:", hintsComponent.container);

Explanation:

1. Import: Import the inputhints function from its location.
2. Arguments:
   • $input: The HTMLInputElement representing the input field.
   • hints: An array of hint strings or a callback function that generates hints dynamically.
   • onSelect: (Optional) A callback function called when a user selects a hint.
3. Return Value: The function returns an object with two properties:
   • getSelected(): Returns the currently selected hint element (HTMLLIElement) or null.
   • container: The HTMLUListElement representing the entire hint list container.

Key Functionalities:

• Hint Generation:
  • If hints is a function, it's called to generate hints dynamically.
  • Hints are filtered based on the user's input using regular expressions (case-insensitive).
• Hint Display:
  • Up to 100 hints are displayed at a time with pagination for longer lists.
  • The hint list automatically positions itself below or above the input field based on available space.
• Hint Selection:
  • Users can select hints using the mouse or keyboard arrows.
  • Selecting a hint populates the input field with the hint value and optionally calls the onSelect callback.
