Introduction¶
dijit._FocusMixin is a mixin to supply the _onFocus() and _onBlur() callbacks on a widget when the widget enters / leaves the focus active stack.
See the dijit.focus documentation for details on the active stack.
Note that the underscore in the name implies not that _FocusMixin is a private class, but rather that it’s a mixin, rather than a widget.
Usage¶
Mixin dijit._FocusMixin when you declare your widget, and then reference _onFocus() and _onBlur():
dojo.declare("MyWidget", [dijit._WidgetBase, dijit._TemplatedMixin, dijit._WidgetsInTemplateMixin, dijit._FocusMixin], {
templateString: '<div><input data-dojo-type="dijit/form/TextBox"><input><input></div>',
_onFocus: function(){
console.log("One of my descendant widgets / nodes got focus");
this.inherited(arguments);
},
_onBlur: function(){
console.log("Focus left me and my descendant widgets");
this.inherited(arguments);
}
});
