PNotify 基于 JavaScript 简单易用消息提示插件

Question

PNotify 是一个 JavaScript 通知插件，前身为 Pines Notify。它旨在提供无与伦比的灵活性，同时很容易使用。它可以提供无阻塞的通知，允许用户无需关闭通知或者提示信息就可以点击通知后面的元素。

PNotify 支持使用 Bootstrap 或者 jQuery UI 的界面，这意味着它能够很容易更换主题。可以在插件官方页面的右上角尝试使用一些现成的主题。它可以在所有主流浏览器中使用，并提供了一致性的界面。

You can include PNotify using Bower, NPM, or a custom download.

PNotify custom download comes with the following files:

• pnotify.custom.js & pnotify.custom.min.js (Minified)
• pnotify.custom.css & pnotify.custom.min.css (Minified)

So here's how you'd include them on your page:

<script type="text/javascript" src="pnotify.custom.min.js"></script>
<link href="pnotify.custom.min.css" media="all" rel="stylesheet" type="text/css" />

Now you can use PNotify like this:

<script type="text/javascript">
    $(function(){
        new PNotify({
            title: 'Regular Notice',
            text: 'Check me out! I\'m a notice.'
        });
    });
</script>

If you are not using any UI library, you can use the included styling, called Bright Theme. It is the default.

If you are using Bootstrap version 2, include this line somewhere before your first notice:

PNotify.prototype.options.styling = "bootstrap2";

If you are using Bootstrap version 3, include this line somewhere before your first notice:

PNotify.prototype.options.styling = "bootstrap3";

If you are using jQuery UI, include this line somewhere before your first notice:

PNotify.prototype.options.styling = "jqueryui";

If you are using Bootstrap 3 with Font Awesome, include this line somewhere before your first notice:

PNotify.prototype.options.styling = "fontawesome";

Stacks

A stack is an object which PNotify uses to determine where to position notices. A stack has two mandatory properties, dir1 and dir2. dir1 is the first direction in which the notices are stacked. When the notices run out of room in the window, they will move over in the direction specified by dir2. The directions can be "up", "down", "right", or "left". Stacks are independent of each other, so a stack doesn't know and doesn't care if it overlaps (and blocks) another stack. The default stack, which can be changed like any other default, goes down, then left. Stack objects are used and manipulated by PNotify, and therefore, should be a variable when passed. So, calling something like new PNotify({stack: {"dir1": "down", "dir2": "left"}}); will NOT work. It will create a notice, but that notice will be in its own stack and may overlap other notices.

Modal Stacks

You can set a stack as modal by setting the "modal" property to true. A modal stack creates an overlay behind it when any of its notices are open. When the last notice within it is removed, the overlay is hidden. If the "overlay_close" property is set to true, then clicking the overlay will cause all of the notices in that stack to be removed.

Example Stacks

var stack_topleft = {"dir1": "down", "dir2": "right", "push": "top"};
var stack_bottomleft = {"dir1": "right", "dir2": "up", "push": "top"};
var stack_modal = {"dir1": "down", "dir2": "right", "push": "top", "modal": true, "overlay_close": true};
var stack_bar_top = {"dir1": "down", "dir2": "right", "push": "top", "spacing1": 0, "spacing2": 0};
var stack_bar_bottom = {"dir1": "up", "dir2": "right", "spacing1": 0, "spacing2": 0};
var stack_context = {"dir1": "down", "dir2": "left", "context": $("#stack-context")};

This stack is initially positioned through code instead of CSS.

var stack_bottomright = {"dir1": "up", "dir2": "left", "firstpos1": 25, "firstpos2": 25};

This is done through two extra variables. firstpos1 and firstpos2 are pixel values, relative to a viewport edge. dir1 and dir2, respectively, determine which edge. It is calculated as follows:

• dir = "up" - firstpos is relative to the bottom of viewport.
• dir = "down" - firstpos is relative to the top of viewport.
• dir = "right" - firstpos is relative to the left of viewport.
• dir = "left" - firstpos is relative to the right of viewport.

To create a stack in the top left, define the stack:

var stack_topleft = {"dir1": "down", "dir2": "right"};

and then add two options to your pnotify call:

addclass: "stack-topleft", // This is one of the included default classes.
stack: stack_topleft

There are several CSS classes included which will position your notices for you:

• stack-topleft
• stack-bottomleft
• stack-bottomright
• stack-modal

You can create your own custom position and movement by defining a custom stack.

• labels: {text: "Spin Around"} - If you are displaying any text, you should use a labels options to support internationalization.

}

Callbacks Module

The callback options all expect one argument, a function, which will be called when that event occurs. They can be included in the options object passed to PNotify() just like the core options. If the function returns false on the "before_open" or "before_close" callback, that event will be canceled.

• before_init - This option is called before the notice has been initialized. It accepts one argument, the options object.
• after_init - This option is called after the notice has been initialized. It accepts one argument, the notice object.
• before_open - This option is called before the notice has been displayed. It accepts one argument, the notice object.
• after_open - This option is called after the notice has been displayed. It accepts one argument, the notice object.
• before_close - This option is called before the notice closes. It accepts one argument, the notice object.
• after_close - This option is called after the notice closes. It accepts one argument, the notice object.

Utility Functions

• PNotify.reload(root) - Reinitialize PNotify. PNotify, in a browser, is initialized with window as the root. Returns the created PNotify object.
• PNotify.removeAll() - Remove all notices.
• PNotify.removeStack(stack) - Remove all the notices in a stack.
• PNotify.positionAll(animate) - Reposition the notices, optionally animating their movement.
• notice.open() - Open the notice.
• notice.remove() - Remove the notice.
• notice.get() - Get the notice's DOM element.

Using PNotify with RequireJS

When they detect AMD/RequireJS, PNotify core defines the named module "pnotify", and PNotify's modules each define names like "pnotify.module". The following example shows the use of the nonblock and desktop modules with RequireJS.

requirejs(['pnotify', 'pnotify.nonblock', 'pnotify.desktop'], function(PNotify){
    PNotify.desktop.permission();
    new PNotify({
        title: 'Desktop Notice',
        text: 'If you\'ve given me permission, I\'ll appear as a desktop notification. If you haven\'t, I\'ll still appear as a regular PNotify notice.',
        desktop: {
            desktop: true
        },
        nonblock: {
            nonblock: true
        }
    });
});
