我的Javascript代码在IE中不起作用，但在其他浏览器中也可以正常工作

Question

I used the following Javascript to password protect my webpage but it's not working for IE, although it works fine for Chrome and Firefox.

<script language="JavaScript">
    var password;
    var pass1="PASSWORD-HERE";
    password=prompt('Whats The Magic Word?',' ');
    if (password==pass1) alert('That Is Correct!');
    else {
      window.location="SITE-LINK";
    }
</script>

What is wrong?

Please check out the link: http://www.xuanyinwen.com/test3.html it work on Firefox and chrome but not IE, when you open the link in IE, it got no message pot up asking for the password, and will automatic go to SITE-LINK. I know this script is not very secure, but I just want use it for a basic protect, just want make it work. thanks for any help!

Answer 1

Try this:

<script>
    prompt('Password:') === '1234' ? 
        alert('Correct!') : 
        window.location.href = 'http://www.google.com';
</script>

The difference is that you are setting the href property instead.

btw I tested this in IE9 beta and it works.

Answer 2

i personally wouldn't just use javascript for password protection...especially when it can be displayed publically.

Check to see if active x is diabled. works on IE 7/8 and quirk mode for me

IE Turn off popup-block and auto enable active x:

open IE go to Tools->Internet Options->Advanced->Security make sure allow active x are allowed. Then go to Tools->Internet Options->privacy and make sure pop up is not blocked.

WARNING: I DO NOT RECOMMAND DOING THIS! AFTER TESTING PLEASE USE DEFAULT I WILL NOT BE RESPONSIBLE

Answer 3

Try this:

<script language="JavaScript">
var password;
var pass1="PASSWORD-HERE";
password = prompt('Whats The Magic Word?',' ');
if (password === pass1)
    alert('That Is Correct!');
else
    window.location="SITE-LINK";
</script>

The difference being 3 equals signs instead of 2. Double-equals in JavaScript lets the runtime try to do type coercion on the items being compared, while with three equals it compares them exactly as-is.

However, as the commenter above noted, using javascript as your only password protection is naive at best.
