 |
|
JavaScript is hard to debug. If I misspell a function, nothing tells
me that I misspelled a function.
When I have some JavaScript in JBuilder that creates a table, JBuilder
will give me an error: Unmatched <TABLE> tag for code such as this:
var content = "<CENTER><TABLE BORDER>"
.... (more code here building the table)
content += "</TABLE></CENTER>"
Should I be using a different tool when I have JavaScript? Trouble
is, I often combine Java and JavaScript. |

The advent of AJAX, it seems to me, has been a
big motivator for improving and increasing the
quality and number of Javascript development
environments. A Google search should yield
quite a number of Javascript edit/debugger/IDEs.
(I currently am not doing any Web UI related
work, so I haven't been keeping up well enough
to know which tool(s) might be considered the best.)
JBuilder doesn't understand Javascript so it's
the wrong tool for that.

That is trouble if what you are saying is that you are
putting Java into your JSPs. Try at all costs to not
do that. Adopt some Web framework for the controller
and action handling aspects, and use tag libraries.
Aim at having no Java code in your JSPs.

Is it in Joi Ellis's Faq-O-Matic?

Finally, please send responses to the newsgroup only.
That means, do not send email directly to me.
Thank you. |

By all means, the only way to do meaningful work with JavaScript, is to
use the free Mozilla/Firefox plugins. Look for Firebug and Web Tools and
install these plugins, at minimum. NetBeans 5.5 and MyEclipse have
some built in features for Java Script, but none are going to provide
you the feedback you desire and none are as robust as the
Firefox/Mozilla tools.
I do AJAX in almost every Web App I build today. Without the Firefox
plugins, my job would be ten times more difficult. With them, I can
debug pretty well.
Another thing, I would be careful to test in IE and Firefox/Mozilla. IE
handles certain events much differently than Firefox/Mozilla. |
