Very good comment Thomas. Documentation should indeed mention when and why to use .text() and .val(). In my experience, 99% of jQuery novices do the same mistake. I suppose they are used to jQuery benign attitude and expect that jQuery "knows" what to do if one call's .text() on the input element. Novices subconsciously, expect form jQ to automagically return the value of the "value" attribute, or some simillar "magic" if element is input or textarea etc. So the jQ doc has to be clear this is not what will happen.
And of course, tutorial needs to explain the reasoning of allowing jQ code like this : $().text() --DBJ On Apr 6, 5:14 pm, Thomas White <[email protected]> wrote: > Chuck, > > Thank you very much for your detailed explanation. > I was so exited about jQuery last couple of days, that I spent most of my > time using it and very little time was left for reading the documentation > ;-). > It could be a good idea to include in the documentation for .text(), a > reference to .val() function stating the deference as you explained it.
