twitterwall example

Can anybody explain how does the html block variable - marked bold - gets initialized in the following method of TwitterSearch.

success: tweets

| playground table tr |

playground := '#playground' asJQuery.

playground empty.

[:html |

html inspect.

table := html table.

table element id: 'twitterwall'.

tweets do: [ :tweet |

tr := html tr.

table append: tr.

Tweet openAt: tr with: tweet

]

] appendToJQuery: playground.

appendToJQuery: is defined in BlockClosure as:

appendToJQuery: aJQuery

self value: (HTMLCanvas onJQuery: aJQuery)

In your snippet html is defined as HTMLCanvas onJQuery: playground .

HTH,

Thanks Felix. I have to remember that everything is an object in Smalltalk. Bit rusty.
