You're right, I had pasted the code snippet from another script and
forgot to change the code. I do only have a question though. If am
only meaning to look for an ID that only exists once, what would be
the syntax for that?
For example, right now I have
$(html).find('#invoice').each(function(){
var invalidDiv = $(this).text();
alert(invalidDiv);
});
If I remove each, how do I call the function that is previously
contained in each?
$(html).find('#invoice')
function(){ <----------------------------------Where do I put this
function?
var invalidDiv = $(this).text();
alert(invalidDiv);
}
Also, on the topic of getting data from a server, right now I am
getting html back from the server and parsing that, however, should I
be using JSON or XML instead? Are these alternative better than html?
HTML is just what I have seen demonstrated so I have just been trying
it out but I am certainly open to new and better ideas.
