How to disable save as dialog in Chrome?

问题

I have following code.

window.onkeypress = function(event) {

    if (event.charCode === 115 && event.ctrlKey) {
        event.preventDefault();
        // your code here....
        alert("'Save As' dialog suppressed!");
    }
};

That code works on Firefox, but in Chrome it doesn't work. Can you help me?

回答1:

You can't. Browsers don't expose (with good reason) the functionality to do this.

Don't annoy your users.
