Check if INSERT mode is ON when typing in an input

I'm trying to calculate the value of an input field on various events regardless of the event caught.

I'm taking into account the events keypress keyup keydown cut paste events (Do I forget anything?).

I'm trying to determine if the text-input INSERT mode is on (default - on), or off. I cannot determine the mode by capturing a key event of that key, though I don't know what was the initial state.

Does anyone know a way? Preferably - a cross browser solution that includes IE8+, Chrome and Firefox.

Any solution, or in the words of Barney Stinson, "scam, con, hustle, hoodwink, gambit, flim flam, stratagem, and bamboozle" that could help me would be appreciated.

Solution

  • For IE only:

    document.queryCommandValue("OverWrite");

    As far as I know, Firefox and Chrome don't have overwrite mode. The insert key doesn't work in those browsers, and they are always in insert mode.

    Moreover, Mac keyboard doesn't have a insert key from the beginning. So Safari also is always in insert mode.
