Javacript: How do you get the caret position and assign it to a variable?-CodePudding

So I'm attempting to create an if/else statement, where the console logs a statement if the enter key is pressed and if the caret has a certain position in an input field. What I can't figure out is how to detect where the caret is positioned and then assign that to a variable.

I have tried windows.getSelection() But this doesn't appear to do anything. Does anyone know how to do this in Javascript?

You can use indexOf on the value of your input to find the index of searched character in a string.

This example outputs it in the console but you could set it to any variable you want.

var input = document.getElementById("myInput");
input.addEventListener("keypress", function(event) {
  if (event.key === "Enter") {
    event.preventDefault();
    console.log(document.getElementById("myInput").value.indexOf("^"));
  }
});

Input fields have input.selectionStart and input.selectionEnd properties, if you don't select anything they return the position of the caret.
