问题
Ok now I am aware that you can listen to keypresses (keydowns keyups etc...) but I would like to TRIGGER a keypress. Like as if the user presses CTRL+S to save.
Short question is, is it possible to use Jquery to trigger 2 key presses at the same time? I have been trying to look this up but all the stuff I found was talking about capturing key presses and not triggering them especially 2 key presses at the same time.
Any ideas how this can be accomplished? If you could lead me to the right track it would be much appreciated.
回答1:
If you want to trigger your own handler code, you should just put that code in a separate function and call the function normally.
If you want to trigger the browser's default functionality, you should give up; that is impossible for security reasons. (Although you may be interested in window.print())

I don't know if you can trigger the key presses but perhaps if you explain what you are specifically trying to achieve you might be able to find a solution?
For example, if you want to trigger ctrl-p to bring up the print dialog you can do this using window.print();
If you want to trigger actions in your own code then you can just call the code directly rather than triggering the key press.
I don't think there is any way to trigger a file | save as (ctrl-s) by using JavaScript though.
