My webpage converted to full screen mode using this following code.
var element = document.getElementById("b");
if (element.mozRequestFullScreen) {
element.mozRequestFullScreen();
} else if (element.webkitRequestFullScreen) {
element.webkitRequestFullScreen();
}
I want to prevent exit from fullscreen mode by clicking esc
I tried this following codes but not working.
document.onkeydown = function (evt) {
alert("1");
if (evt.keyCode == 27) evt.preventDefault();
}
If i press escape it first exit from full screen and from next press the above function will work and alert "1".
I tried the following codes also but no benefit
function keyUp(){
alert("sdd");
document.querySelector("#start").addEventListener("keydown",function(e){
var charCode = e.charCode || e.keyCode || e.which;
if (charCode == 27){
return false;
}
});
}
and
document.onkeydown = function (e) {
if(e.which == 27){
return false;
}
}
Anybody know how to prevent exiting from full screen mode. Or how to convert webpage to fullscreen mode using f11 key programatically?
