Javascript window.onsave event -


is there way detect/intercept when user tries save page? allow me embed external files , provide user fully-functional offline app.

the other solution embedding resources beginning, consumes many resources , and takes away of dynamic capability.

any alternative not require any external libraries (including jquery, respect it, loads project) acceptable.

there no window.onsave event find. however, listen ctrl+s keystroke intercepted.

var isctrl = false; document.onkeyup=function(e){     if(e.keycode == 17) isctrl=false; }  document.onkeydown=function(e){     if(e.keycode == 17) isctrl=true;     if(e.keycode == 83 && isctrl == true) {         //run code ctrl+s -- ie, save!         return false;     } }

code courtesy of: how capture ctrl-s without jquery or other library?
