Path to a blank 1x1 image. Used by <img> nodes in templates that really get their image via CSS background-image.

Deprecated. Instead of attributeMap, widget should have a _setXXXAttr attribute for each XXX attribute to be mapped to the DOM.

attributeMap sets up a "binding" between attributes (aka properties) of the widget and the widget's DOM. Changes to widget attributes listed in attributeMap will be reflected into the DOM.

For example, calling set('title', 'hello') on a TitlePane will automatically cause the TitlePane's DOM to update with the new title.

attributeMap is a hash where the key is an attribute of the widget, and the value reflects a binding to a:

• DOM node attribute

  focus: {node: "focusNode", type: "attribute"} Maps this.focus to this.focusNode.focus

• DOM node innerHTML

  title: { node: "titleNode", type: "innerHTML" } Maps this.title to this.titleNode.innerHTML

• DOM node innerText

  title: { node: "titleNode", type: "innerText" } Maps this.title to this.titleNode.innerText

• DOM node CSS class

  myClass: { node: "domNode", type: "class" } Maps this.myClass to this.domNode.className

If the value is an array, then each element in the array matches one of the formats of the above list.

There are also some shorthands for backwards compatibility:

• string --> { node: string, type: "attribute" }, for example:

"focusNode" ---> { node: "focusNode", type: "attribute" }

• "" --> { node: "domNode", type: "attribute" }

Root CSS class of the widget (ex: dijitTextBox), used to construct CSS classes to indicate widget state.

Designates where children of the source DOM node will be placed. "Children" in this case refers to both DOM nodes and widgets. For example, for myWidget:

<div data-dojo-type=myWidget>
    <b> here's a plain DOM node
    <span data-dojo-type=subWidget>and a widget</span>
    <i> and another plain DOM node </i>
</div>

containerNode would point to:

<b> here's a plain DOM node
<span data-dojo-type=subWidget>and a widget</span>
<i> and another plain DOM node </i>

In templated widgets, "containerNode" is set via a data-dojo-attach-point assignment.

containerNode must be defined for any widget that accepts innerHTML (like ContentPane or BorderContainer or even Button), and conversely is null for widgets that don't, like TextBox.
