Re: Execute jQuery script upon #onAjaxComplete?

Well, with help from Esteban the (via chat), this ended up working as I
expected:


html document addLoadScript: (
html jQuery document onAjaxComplete:(
html jQuery
ajax
global: false; "to avoid inifite recursion"
script: [ :s | s <<  ( (html jQuery id: self classicMenuComponent
systemMessageNotifier mainDivId)
replaceWith: [:r | self classicMenuComponent systemMessageNotifier
renderContentOn: r ]
) ]
)
)



Thanks for the help!
