Get input character position in contenteditable
I have a contenteditale div in my Angular 6 project
<div contenteditable="true" (input)="checkContent($event)"></div>
When user types a character, I would like to get the position of the character.
What I'm actualy trying to do is to check if there is a '@' before the input character and If yes then count characters between '@' and input character
Examples(considering the Uppercase character is the last entered):
hellO // postion = 4
hello World // postion = 6
Hello world // postion = 0
For now I can get the entered character from the component with event.data
checkContent(event: any){
console.log(event.data);
}
How can I get the position of the last entered character ?
javascript angular contenteditable

Can you clarify one thing, once any character is entered from where you have to match the position ? I mean which string or content ?

But that may not be trivial depending on what you are trying to accomplish. Without more background there is no simple answer or answers may not meet your needs. You mentioning typing, but what about pasting for example? Or corrections user makes ? A proper explanation of the higher level problem you are trying to solve would help

How about using the keydown and keyup event to get the difference between 2 strings, then you will find exactly the index of last character.

If I understand what you want correctly, then this works...
1 - Insert a temporary span (with an id) at the cursor position that contains a character you will never type (I use hex 7F).
2 - Get the textContent (innerText) of your div into a Variable.
3 - Delete the temporary span.
4 - Use Variable.search(/x7F/) (in my example) to get position of current character.
