passing the string "input[type=radio][name='type'][value=selectThis]"
into $$ as the selector. David's suggestion fixes that by using the
*value* of selectThis rather the actual text "selectThis". As the live

This is probably more of a question for the jQuery forums, or the

Hi,
Based on that code, the `this` value in `_msoSGrid.load` definitely
refers to `_msoSGrid`. What makes you think the context during the
call is wrong? I'd say there's an issue with the actual `load`
function, because the call to it is absolutely fine.

I've never had to do the above in the
real world. Perhaps someone with real-world experience will chime in,
and if they do, they're likely to have higher-quality information.

and uses `eval` under-

`json_parse.js` or `json_parse_state.js`, neither of which uses
`eval`. The former is a recursive-descent parser, the latter is a
state machine.

Well, that's not good.
In any case, you can find the license with the source code:
https://github.com/sstephenson/prototype/blob/master/LICE
n't, it keeps using its prototype's property (if
any).
The thing with your `intro` property is that nothing is ever assigned
to it, and so no instance had its own `intro` property, and they were
all falling back on the one on `Parent.prototype`. All you ever did in
the `ChildA` and
with `A`'s loop.

function B()

mention the complications around `this`) just to loop through an
array. People are free to do that if they like, but it's not remotely
necessary and it's certainly not always appropriate. There's nothing
wrong with a nice, simple `for` loop.
Just my two cents.

completely lock up the UI of the browser (not just your page, the
entire browser) during the time your ajax call is being processed.
Locking up the UI for 1-30 seconds is a Bad Thing(tm). :-)

Simple Controls Gallery code suggests that it's
noConflict-compatible and it doesn't have any `for..in` loops, so if
you add `noConflict` after loading jQuery and before loading
Prototype, you should be okay. E.g.:
jQuery.noConflict();

Prototype adds `Array#indexOf` to implementations that don't have it
natively.
