You might be seeing a trend here if you have gotten this far in the tutorial, in that not only has Dojo abandoned its dependency on the global namespace and adopted some new patterns, it has also broken out some of "core" functionality into modules and what is more core to a JavaScript toolkit than DOM manipulation.
Well, that too has been broken up into much smaller chunks and modularized. Here is summary of the modules and what they contain:
| Module | Description | Contains |
|---|---|---|
| dojo/dom | Core DOM functions | byId() isDescendant() setSelectable() |
| dojo/dom-attr | DOM attribute functions | has() get() set() remove() getNodeProp() |
| dojo/dom-class | DOM class functions | contains() add() remove() replace() toggle() |
| dojo/dom-construct | DOM construction functions | toDom() place() create() empty() destroy() |
| dojo/dom-form | Form handling functions | fieldToObject() toObject() toQuery() toJson() |
| dojo/io-query | String processing functions | objectToQuery() queryToObject() |
| dojo/dom-geometry | DOM geometry related functions | position() getMarginBox() setMarginBox() getContentBox() setContentSize() getPadExtents() getBorderExtents() getPadBorderExtents() getMarginExtents() isBodyLtr() docScroll() fixIeBiDiScrollLeft() |
| dojo/dom-prop | DOM property functions | get() set() |
| dojo/dom-style | DOM style functions | getComputedStyle() get() set() |
