Javascript - How To call the same Method for different Elements with different IDs?

In JavaScript, you can define a function that takes an element ID as a parameter and then call that function with different element IDs. Here's an example:

<!DOCTYPE html> <html> <head> <title>Call Same Method for Different Elements</title> </head> <body> <button id="button1" onclick="handleButtonClick('button1')">Button 1</button> <button id="button2" onclick="handleButtonClick('button2')">Button 2</button> <button id="button3" onclick="handleButtonClick('button3')">Button 3</button> <script> function handleButtonClick(elementId) { var element = document.getElementById(elementId); console.log('Button clicked:', elementId); // Your logic here } </script> </body> </html>

In this example:

  • Each button has a unique id attribute.
  • The onclick attribute is set to call the handleButtonClick function with the respective id when the button is clicked.
  • The handleButtonClick function takes an elementId parameter, uses document.getElementById to retrieve the element with that ID, and logs a message to the console.

This way, you can use the same method (handleButtonClick) for different elements with different IDs by passing the element ID as a parameter. Adjust the logic inside the function based on your specific requirements.

Examples

  1. "JavaScript call method for multiple elements by ID"

    • Code:
      function myMethod(elementId) { const element = document.getElementById(elementId); // Your method logic for the element }
    • Description: Defines a method myMethod that takes an element ID as an argument and performs logic on the corresponding element.

  2. "JavaScript loop through array of IDs and call method"

    • Code:
      const elementIds = ['element1', 'element2', 'element3']; function myMethod(elementId) { const element = document.getElementById(elementId); // Your method logic for the element } elementIds.forEach(myMethod);
    • Description: Uses an array of element IDs and calls the myMethod for each element.

  3. "JavaScript call method for all elements with a common class"

    • Code:
      const elements = document.getElementsByClassName('commonClass'); function myMethod(element) { // Your method logic for the element } Array.from(elements).forEach(myMethod);
    • Description: Calls the myMethod for all elements with a common class.

  4. "JavaScript call method for elements with specific prefix IDs"

    • Code:
      function callMethodForPrefix(prefix) { const elements = document.querySelectorAll(`[id^=${prefix}]`); function myMethod(element) { // Your method logic for the element } elements.forEach(myMethod); } callMethodForPrefix('specificPrefix');
    • Description: Defines a generic method callMethodForPrefix that calls myMethod for elements with specific prefix IDs.

  5. "JavaScript call method for elements within a parent container"

    • Code:
      const container = document.getElementById('parentContainer'); const elements = container.getElementsByTagName('div'); function myMethod(element) { // Your method logic for the element } Array.from(elements).forEach(myMethod);
    • Description: Calls the myMethod for elements within a parent container.

  6. "JavaScript call method for elements based on data attribute"

    • Code:
      const elements = document.querySelectorAll('[data-custom-id]'); function myMethod(element) { // Your method logic for the element } elements.forEach(myMethod);
    • Description: Calls the myMethod for elements with a specific data attribute.

  7. "JavaScript call method for elements with dynamic IDs"

    • Code:
      function callMethodForDynamicIds(baseId, count) { for (let i = 1; i <= count; i++) { const elementId = `${baseId}-${i}`; const element = document.getElementById(elementId); // Your method logic for the element } } callMethodForDynamicIds('dynamicElement', 5);
    • Description: Calls the myMethod for elements with dynamically generated IDs.

  8. "JavaScript call method for first element with a specific class"

    • Code:
      const element = document.querySelector('.specificClass'); function myMethod(element) { // Your method logic for the element } myMethod(element);
    • Description: Calls the myMethod for the first element with a specific class.

  9. "JavaScript call method for elements matching a selector"

    • Code:
      const elements = document.querySelectorAll('.commonClass, #element2, [data-custom-id]'); function myMethod(element) { // Your method logic for the element } elements.forEach(myMethod);
    • Description: Calls the myMethod for elements matching multiple selectors.

  10. "JavaScript call method for all elements within the body"

    • Code:
      const elements = document.body.getElementsByTagName('*'); function myMethod(element) { // Your method logic for the element } Array.from(elements).forEach(myMethod);
    • Description: Calls the myMethod for all elements within the body.
