Sorry if this is so basic...
Right now in my code I have the following Event.observe statement:
Event.observe($('msg'), 'keypress', txKeyPressHandler, true);
This works fine: if a key is pressed in the "msg" field the
txKeyPressHandler function is invoked and makes an asynchronous call to the
server and all is fine.
What I want to do is something similar, but with clicks ordinary links that
I have generated dynamically.
So there might be:
link1
link2
link3
etc., with some identifying parameters along with each link.
Right now I have these links, but I am just clicking on them which opens up
a little window that displays the results coming back from the server. That
works fine, functionally.
But I would like, instead, to click on them and invoke an asynchronous call,
like I am doing above with the "msg" field, so I can just smoothly display
my results right there without opening up another window.
Should I:
1. Include an onclick to javascript which calls the click handler in each
link? If so, what is the proper syntax for this?
or
2. Should I have an Event.observe statement that checks for click events on
the links? If so, what should the <a> tag parameters be? For example, does
each link need its own "id" parameter? Can an Event.observe observe more
than one id at a time? Or is there some other way I should do this, like
observe clicks and then somehow determine which element was clicked on from
that and what its parameters are?
Which way do you think is better?
Thanks!
