How Can I Insert Text at the Cursor Position in a Textbox Using JavaScript/jQuery?

Inserting a Text where the Cursor is with Javascript/jquery

When working with text-heavy pages, the need to insert text at specific points can arise, especially when triggering events using links. This article delves into how to insert text at the cursor's position or append it to the focused textbox regardless of the element type using JavaScript or jQuery.

One effective solution leverages the insertAtCaret function. It identifies the type of browser (Internet Explorer or Firefox) and the position of the cursor based on the element's selectionStart property or createRange method. The function then modifies the element's content, adding the desired text at the cursor position.

To implement this solution, simply include the provided function and event handler in your code:

function insertAtCaret(areaId, text) {
  // Function to insert text at the cursor position
  ...
}

// Event handler to insert text on link click
document.querySelector('a').addEventListener('click', function() {
  insertAtCaret('textareaid', 'text to insert');
});

By utilizing this technique, you can dynamically insert text at the cursor's position, enhancing user experience and simplifying text manipulation on your web pages.
