Question

ANSWER FOUND!

I’m reading an xml document and I am sending this to a function

$(data).find('colleges').attr('next')

that returns discipline and javascript is thinking it’s a variable, can I some how get the attribute in the tag and have it return as a string like 'discipline'

Is there a toString()-type method that I could add onto the selection?

$(data).find('colleges').attr('next').toString()

The issue I am having is that I am sending that to a function

createSelect( $(data).find('colleges').attr('next') )

but firebug is giving me an error saying that the value, discipline, is undefined? Why is javascript reading discipline as a var and not a string?

Answer 1

If this…

$(data).find('colleges')

…doesn’t find any matches ( <colleges>...</colleges> ), then this…

.attr('next')

…will return undefined.

The first thing you should do is test to see if the .find() found anything.

alert( $(data).find('colleges').length );

If the alert gives you 0, then there were no matches, and you’ll have to inspect your data to see if it contains what you expect.
