So i have just made a simple HTML page in which a JS script runs when the page loads. But the problem is that it just goes infinite after asking password. I tried to find some solutions but failed to do the same. Please help. Below is the code.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Alert test</title>
</head>
<body onload="alert()">
<script>
function alert() {
var uname, pass, corr_uname = "admin", corr_pass = "admin";
while(!uname) {
uname = prompt("Enter Username: ");
}
while(!pass) {
pass = prompt("Enter Password: ");
}
if((uname == corr_uname) && (pass == corr_pass)) {
alert("Access Granted!!");
} else {
alert("Access Denied!");
alert();
}
}
</script>
<h1>Welcome!</h1>
</body>
</html>
The funny thing is that when i run the same code (JS runs after clicking a button) in W3Schools, it just works fine!!
>Solution :
The problem is that you have created a function named alert
which already exists in javascript, so you are calling it recursively and infinitely.
Solution fix
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Alert test</title>
</head>
<body onload="alert2()">
<script>
function alert2() {
var uname, pass, corr_uname = "admin", corr_pass = "admin";
while(!uname) {
uname = prompt("Enter Username: ");
}
while(!pass) {
pass = prompt("Enter Password: ");
}
if((uname == corr_uname) && (pass == corr_pass)) {
alert("Access Granted!!");
} else {
alert("Access Denied!");
myFunction();
}
}
</script>
<h1>Welcome!</h1>
</body>
</html>
I renamed your functional alert
to alert2
.
Kindly accept it as answer if it works for you, thanks!
