Online JavaScript Calculator

Pretty cool. I would enhance it to support double clicks. If you double click a number it would be equivalent to clicking on it twice. The other buttons could ignore the double click. Not critizing, just a suggestion!

That's an excellent idea. Doing this should require a fairly simple change. For each of the number buttons, you would need both onclick and ondblclick events. For example, the code following shows for the number 7 button:

ondblclick="SetNumber(7);" onclick="SetNumber(7);"

(Note that using just the ondblclick event would mean that users would always have to double-click the button. Using both allows users to either single-click or double-click the numbers.)

I would recommend replacing the sample:

<a href="javascript:OpenCalculator();">Calculate Numbers</a>

with

<a href="serversidecalc.aspx" onclick="OpenCalculator();">Calculate Numbers</a>

and modify OpenCalculator(); to return false;

By doing this, things don't break when JS is off or not supported. Returning false to onclick tells it not to handle the actual href destination; if js is off or not supported, it won't do the onclick, just the href making the web application more robust.

The href destination would probably be a JS is needed page, but in this case, you could easily make a page that roundtrips and does the calculations on the server as an alternative.

How did you know I keep a calculator in my wallet? Unless... Hey! Where's my wallet?!

To student:

I just checked the working sample, and it does work fine. However, you may have found a bug. If this is the case, please send me exact repro steps so that I can try to fix. Otherwise, feel free to grab the code and tweak it for yourself.

Just click the text "example page" in the page above, and then click "Calculate Numbers". This gives you the calculator page. Once you have the calculator page, you can click the link "View code" to get the full code for the calculator.

Hope this helps.
Lisa

This doesn't work in Firefox or any other Mozilla browser because they don't support the ShowModalDialog function. There are workarounds; you might want to update your code to work across the two most popular browsers...
