In most pages, if your doing an action, (like editing, creating), and when I attempt to exit, it mostly prompts me if I really want to exit. The dialog gives me two options: leave or cancel and continue. How do you accomplish this in JavaScript? Do I have to use a meta element?
And please don't mention
beforeunload
, unless it's the true and only way to accomplish this.
Why not mention onbeforeunload
? It's the built in way to do so, and I don't see a problem using it.
function myConfirmation() {
return 'Are you sure you want to quit?';
}
window.onbeforeunload = myConfirmation;
我用的是:
onClick="return confirm('Sure you want to exit..?')"
window.onbeforeunload = function() {
if(confirm('are you sure to exit?'))
return true;
else
return false;
};
