Recently, I encountered the following code snippet:
document.getElementById("myDiv").addEventListener("keydown", function (e){
if (e.keyCode == 8) {
this.innerHTML += "⠀".repeat(4);
e.preventDefault();
}
//moves cursor
});<div id="myDiv" contenteditable="true">Enter text.</div>Give this method a try.
const element = document.getElementById("myDiv");
const selection = window.getSelection();
const startOffset = selection.getRangeAt(0).startOffset;
element.innerHTML += 'Additional text to insert'; // Add your operations here
const newRange = document.createRange();
newRange.setStart(element.childNodes[0], startOffset);
newRange.collapse(true);
selection.removeAllRanges();
selection.addRange(newRange);
Note that browser compatibility may need further adjustments, but this is the main idea.
