window.location doesn't work in IE6. You probably want document.location.

<pre><code>if ("cool" == prompt('Please enter your password to view this page!', '')) {
 alert('Password Correct! Click OK to enter!');
} else {
 document.location = "http://www.pageresource.com/jscript/jpass.htm";

blocks|key|5092692|text|默认情况下，IE7会禁用提示功能。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5092693|正如我之前的每个人所说的，除非这只是一个学习javascript类型的endevour+--“保护”是无用的。所有人所要做的就是禁用JS和/或查看您的源代码以了解您正在重定向的位置。|5092694|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

IE7 has the prompt functionality disabled by default.

And as everyone before me has said unless this is just a learning javascript type endevour - the "protection" is useless. All anyone has to do is disable JS and/or look at your source for where youre redirecting.

blocks|key|1256261|text|试着用大括号括起if：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1256262|if+(password==pass1){

Try wrapping curly braces around your if: 

<pre><code>if (password==pass1){
 alert('Password Correct! Click OK to enter!');
} else {
 window.location="http://www.pageresource.com/jscript/jpass.htm";
}
</code></pre>

You probably don't really need that hide stuff anymore either. Good luck on your learning.

blocks|key|5092764|text|好的，首先，我希望你这样做只是为了使用javascript，因为任何人都可以通过查看源代码来快速绕过你的安全性。为了管理一个站点的登录访问，你真的应该使用服务器端的实现，如php，jsp，asp等。这些站点使用密码登录，并在服务器上比较它，而普通用户看不到它。无论如何，你的下面的代码应该可以工作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5092765|<!DOCTYPE+HTML+PUBLIC+"-//W3C//DTD+HTML+4.0+Transitional//EN">

Ok, firstly I hope you are just doing this to play with javascript because anyone will be able to bypass your security in a snap just by looking at the source code. To manage login access to a site you really should be using a server side implementation such as php, jsp, asp etc. Those sites take the password login and compare it on the server which the normal user cannot see. Anyway your code below should work:

<pre><code>&lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"&gt;
&lt;html&gt;
 &lt;head&gt;
 &lt;title&gt;HTML Test&lt;/title&gt;
 &lt;script type="text/javascript"&gt;
 function check()
 {
 var password;
 var pass1="cool";
 password=prompt('Please enter your password to view this page!',' ');
 if (password==pass1)
 alert('Password Correct! Click OK to enter!');
 else
 document.location="http://www.pageresource.com/jscript/jpass.htm";
 }
 &lt;/script&gt;
 &lt;/head&gt;
 &lt;body onload="check()"&gt;
 &lt;/body&gt;
&lt;/html&gt;
</code></pre>

blocks|key|3624766|text|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3624767|我认为你在'if‘行的末尾遗漏了一个乱七八糟的东西，在'else’行的开头又漏掉了一个，或者，删除了现在已经存在的两个。|ordered-list-item|3624768|3624769|So，要么是这个：|offset|length|style|BOLD|3624770|if+(password==pass1)+{

<ol>
<li>I think you are missing one squiggly at end of 'if' line, and another at beginning of 'else' line, or, remove the two that are existing now . </li>
</ol>

So, either this:

<pre><code>if (password==pass1) {
 alert('Password Correct! Click OK to enter!');
} else {
 window.location="http://www.pageresource.com/jscript/jpass.htm";
}
</code></pre>

.. or this (although I never code this way personally) ..

<pre><code>if (password==pass1)
 alert('Password Correct! Click OK to enter!');
else
 window.location="http://www.pageresource.com/jscript/jpass.htm";
</code></pre>

should work.

Also, try window.location.href instead of just window.location. 

<pre><code>window.location.href = "http://www.pageresource.com/jscript/jpass.htm";
</code></pre>

Of course, as mentioned ny others, your approach is not secure using password on client side (&lt;!--hide does NOT hide the javascript from the source code view).

Hope this helps -

blocks|key|5092627|text|它看起来像你的第一行js：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5092628|<!--hide|code-block|syntax|javascript|5092629|应该是：|5092630|//+<!--+hide|5092631|但看起来你可能还有其他问题。先试试这个吧！|5092632|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

it looks like your first line of js: 

<pre><code>&lt;!--hide

should be :

<pre><code>// &lt;!-- hide

But it looks liek you may have other problems as well. Try that first!

blocks|key|1308422|text|如果我的JavaScript只在IE中中断，我做的第一件事就是通过JSLint运行它，这是一个检查JS代码错误的免费工具。这可能会揭示导致IE阻塞的原因。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1308423|entityMap|0|LINK|mutability|MUTABLE|url|http://jslint.com/^0|X|6|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

If my JavaScript only breaks in IE, the very first thing I do is run it through <a href="http://jslint.com" rel="nofollow noreferrer">JSLint</a>, a free tool that checks your JS code for errors. This will likely reveal what's causing IE to choke.

blocks|key|3624673|text|不要那样做！您正在向用户发送密码。用户所要做的就是“查看源代码”，它就在那里。或者，用户可以获得密码对Javascript源代码隐藏的任何信息。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3624674|客户端验证对于数据格式之类的事情非常有用，但是任何敏感的事情都不应该在客户端完成，所有数据都应该在服务器上再次验证。请记住，恶意用户可以向您发送任何内容，完全绕过您的Javascript。|3624675|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

DON'T DO THAT!!! You're sending the user the password. All the user has to do is "View Source" and it's right there. Alternatively, the user can get whatever information the password was hiding from the Javascript source.

Client-side validation is great for things like data formats, but nothing that is sensitive should ever be done client-side, and all data should be validated again on the server. Remember, a malicious user can send you anything, bypassing your Javascript entirely.

blocks|key|5092824|text|这里有一小段代码|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5092825|if+(password==pass1)
alert('Password+Correct!+Click+OK+to+enter!');

}|5092828|其次，与php和其他类似C的语言不同的是，不要在新的行中开始大括号……|5092829|在javascript中，当解释器计算脚本时，它会查找指定语句结尾的分号，|5092830|如果找不到分号，则将最接近的前一个换行符替换为分号|5092831|因此，您的else块的计算结果为：|5092832|else;

its this bit of code here

<pre><code>if (password==pass1)
alert('Password Correct! Click OK to enter!');
else
{
window.location="http://www.pageresource.com/jscript/jpass.htm";
}
</code></pre>

first of all wrap the <code>alert</code> bit in curly braces to read

<pre><code>if (password==pass1){
 alert('Password Correct! Click OK to enter!');
}
</code></pre>

secondly, unlike php and other C like languages, do not start braces in a new line... 
in javascript, when a script is evaluated by the interpreter, it looks for a semicolon designating the end of a statement, 
if a semicolon is not found, the closest previous line break is replaced with a semicolon 

So, your <code>else</code> block is evaluated as :

<pre><code>else;
{;
window.location="http://www.pageresource.com/jscript/jpass.htm";
};
</code></pre>

instead write it as 

<pre><code>else{
 window.location="http://www.pageresource.com/jscript/jpass.htm";
}
</code></pre>
