1,000,863 | 1,000,864 | Javascript rounding issue | <p>I've got a weird maths/rounding problem in Javascript.</p>
<p>The snippet below is a very basic example of the code I'm running. Obviously it's not this exact code, but I'm taking a decimal value from a text box, working out a percentage and taking this away from one.</p>
<pre><code>var ten = "10";
var eight = "8";
alert(1 - (eight/ten));
</code></pre>
<p>The problem is the answer is 0.2 but the calculation returns 0.1999999999999996. Yet if I do 1 + (eight/ten) 1.8 is returned. What is going on?</p>

5,204,237 | 5,204,238 | Valid javascript object property names | <p>I'm trying to work out what is considered valid for the property name of a javascript object. For example</p>
<pre><code>var b = {}

b['colour'] = "green"; // Ditto
alert(b['-^colour']); // Ditto
alert(b.colour); // Ditto
for(prop in b) alert(prop); // Ditto
//alert(b.-^colour); // Fails (expected)
</code></pre>
<p>This <a href="http://stackoverflow.com/questions/1661197/valid-characters-for-javascript-variable-names">post</a> details valid javascript variable names, and '-^colour' is clearly not valid (as a variable name). Does the same apply to object property names? Looking at the above I'm trying to work out if</p>
<ol>
<li><p>b['-^colour'] is invalid, but works in all browsers by quirk, and I shouldn't trust it to work going forward</p></li>
<li><p>b['-^colour'] is completely valid, but it's just of a form that can only be accessed in this manner - (it's supported so Objects can be used as maps perhaps?)</p></li>
<li><p>Something else</p></li>
</ol>
<p>As an aside, a global variable in javascript might be declared at the top level as</p>
<pre><code>var abc = 0;
</code></pre>
<p>but could also be created (as I understand it) with </p>
<pre><code>window['abc'] = 0;
</code></pre>
<p>the following works in all the above browsers</p>
<pre><code>window['@£$%'] = "bling!";
alert(window['@£$%']);
</code></pre>
<p>Is this valid? It seems to contradict the variable naming rules - or am I not declaring a variable there? What's the difference between a variable and an object property name?</p>

I think it's an ASP.Net application (there's a form on the login.aspx [hint1] that has id="aspnetForm" [hint2]), and I thought, in my perfectly-run imagination, that all I had to do was pass users credential in as parameters to the login page (I've injected their usernames into the vendor's database, and I can manually log in fine with those), and it just worked.

5,997,133 | 5,997,134 | JavaScript keyDown Does Not Fire | <p>I have a page in a modal window where I am displaying a slide show. The intended audience is for tablet users and they navigate the show by swiping from the right to the left or the left to the right to see the next or previous slide. This all works beautifully. </p>
<p>However, in the event that someone does view the page using a computer, I would like them to be able to navigate using the arrow keys on their keyboard. I'm able to detect the keystroke, but only after the user has clicked inside the modal window. I would really like the user to not have to click anywhere before the keyboard navigation shows up. It doesn't seem to matter what I try, this is always the problem.</p>
<p>Please note, because this is a modal window, it brings its contents in through the use of an iFrame.</p>

it seems that there are conflict between two jquery. if i remove <code><script type="text/javascript" src="/js/jquery-1.4.2.min.js"></script></code> from page2.html it work fine because index.html include this line but page2.html will not work independently. i tried $.noConflict(); and it doesnt work.</p>

<p>I am trying to convert a HTML table to a multidimensional array. I have converted the table into a long string, each cell being delimited with a comma and each row being delimited with a semicolon. </p>
<p>I am not exactly sure how to build the multidimensional array from this string. This is what I have tried so far:</p>
<pre><code><?php
$outerARR = explode(";", $preparedstring);
$arr = array
(
foreach ($outerARR as $arrvalue) {
$innerarr = explode(",", $arrvalue);
$innerarr[0]=>array
(
$innerarr[];
)
}
);
?>
</code></pre>
<p>this gives me a syntax error near the </p>
<blockquote>
<p>$arr = array</p>
<blockquote>
<p>(</p>
</blockquote>
</blockquote>
<p>opening parenthesis.</p>
