dijit.MenuBar¶

The MenuBar widget models a typical menu bar like the quintessential “File” menu on (virtually?) all programs.
Introduction¶
PopupMenuBarItem widgets are the actual items in the menu, and like PopupMenuItem it displays a submenu or other widget below it. A PopupMenuBarItem always has two child nodes: a tag with the displayed label (usually in a SPAN tag), and a widget to be popped up, typically a dijit.Menu widget.
There’s also a dijit.MenuBarItem widget if you need an entry in your MenuBar that doesn’t have a drop down.
Examples¶
Programmatic example¶
dojo.require("dijit.MenuBar");
dojo.require("dijit.PopupMenuBarItem");
dojo.require("dijit.Menu");
dojo.require("dijit.MenuItem");
var pMenuBar;
dojo.ready(function(){
pMenuBar = new dijit.MenuBar({});
var pSubMenu = new dijit.DropDownMenu({});
pSubMenu.addChild(new dijit.MenuItem({
label:"File item #1"
}));
pSubMenu.addChild(new dijit.MenuItem({
label:"File item #2"
}));
pMenuBar.addChild(new dijit.PopupMenuBarItem({
label:"File",
popup:pSubMenu
}));
var pSubMenu2 = new dijit.DropDownMenu({});
pSubMenu2.addChild(new dijit.MenuItem({
label:"Edit item #1"
}));
pSubMenu2.addChild(new dijit.MenuItem({
label:"Edit item #2"
}));
pMenuBar.addChild(new dijit.PopupMenuBarItem({
label:"Edit",
popup:pSubMenu2
}));
pMenuBar.placeAt("wrapper");
pMenuBar.startup();
});
<div id="wrapper"></div>
Declarative markup¶
Creation from markup is even easier.
dojo.require("dijit.MenuBar");
dojo.require("dijit.PopupMenuBarItem");
dojo.require("dijit.DropDownMenu");
dojo.require("dijit.MenuItem");
<div data-dojo-type="dijit.MenuBar" id="navMenu">
<div data-dojo-type="dijit.PopupMenuBarItem">
<span>File</span>
<div data-dojo-type="dijit.DropDownMenu" id="fileMenu">
<div data-dojo-type="dijit.MenuItem" data-dojo-props="onClick:function(){alert('file 1');}">File #1</div>
<div data-dojo-type="dijit.MenuItem" data-dojo-props="onClick:function(){alert('file 2');}">File #2</div>
</div>
</div>
<div data-dojo-type="dijit.PopupMenuBarItem">
<span>Edit</span>
<div data-dojo-type="dijit.DropDownMenu" id="editMenu">
<div data-dojo-type="dijit.MenuItem" data-dojo-props="onClick:function(){alert('edit 1');}">Edit #1</div>
<div data-dojo-type="dijit.MenuItem" data-dojo-props="onClick:function(){alert('edit 2');}">Edit #2</div>
</div>
</div>
</div>
