jQWidgets jqxNavBar Disabled 属性

The jqxNavBar is a jQuery widget that allows you to create a navigation bar that displays a list of items that can be clicked to navigate to different parts of your application. You can use the "disabled" property to disable certain items in the navigation bar.

To use the "disabled" property, you can simply set the "disabled" option to true for the item(s) you want to disable when you initialize the jqxNavBar widget. For example:

$('#jqxNavBar').jqxNavBar({
    items: [
        { label: 'Home', disabled: false },
        { label: 'About', disabled: true },
        { label: 'Contact', disabled: false }
    ]
});

In this example, the item with the label "About" is disabled because its "disabled" option is set to true.

When an item is disabled, it will appear grayed out and cannot be clicked. Additionally, any event handlers attached to the item will not be triggered.

Note that you can also dynamically update the "disabled" property of an item after the jqxNavBar widget has been initialized by calling the "setItemDisabled" method. For example:

// Disable the "About" item after the jqxNavBar widget has been initialized
$('#jqxNavBar').jqxNavBar('setItemDisabled', 'About', true);

In this example, the "About" item is disabled by calling the "setItemDisabled" method and passing in the item's label and the value true.
