Look at a picture first.

If our program has a progress bar at the top every time the page is switched, it will greatly improve the user experience.

Npropgress plug-in

Github address

Simple use-Vue project as an example (for detailed configuration, click the github address above to view the document)

The simplest way to use it: a progress bar is loaded every time the vue project switches routes.

Installation

Npm install-save nprogress

Introduce

Introduced in the routing configuration file, written to the two hook functions before and after the route is loaded

/ / introduce import NProgress from 'nprogress';import' nprogress/nprogress.css';// progress bar configuration item to write NProgress.configure ({showSpinner: false}); / / Route jump before hook function-execute progress bar to start loading router.beforeEach ((to, from, next) = > {NProgress.start ();}); / / Route jump hook function-execution progress bar loading ends router.afterEach () = > {NProgress.done () });

If introduced by cdn, it is as follows

Set the progress bar color

If it is a normal vue project, put the style in a css file and introduce it in the project main file main.js. Here is the css style

# nprogress .bar {background: # 00CC00! important; / / Custom Color}

Configuration item

Manually control the progress bar increment. The parameter range is 0-1. If no parameter is passed, each call will be incremented randomly, but it will never reach 100%, unless NProgress.done () is called.

/ / if the status of the progress bar before the call 50%NProgress.inc (0.2); / / 70% after the call

Progress bar loading completed

With parameter true: even if NProgress.start () is not called, the progress bar will be displayed and executed from 0% to 100%, and then disappear.

No arguments: if NProgress.start () is not called, this command will do nothing.

NProgress.done (true)

Minimum percentage when starting the progress bar (default is 0.08)

NProgress.configure ({minimum: 0.3})

You can use a template to change the tag. To keep the progress bar working, keep a role='bar' element in it and refer to the default template.

/ / default template NProgress.configure ({template: "..."}); / / example NProgress.configure ({template: "change tag"})

Use easing and speed to adjust animation settings, ease can pass CSS3 buffer animation strings (such as ease, linear, ease-in, ease-out, ease-in-out, cubic-bezier), and speed is the animation speed (in ms). The default is ease 200, respectively

NProgress.configure ({easing: 'ease', speed: 200})

Turn off automatic increment behavior

NProgress.configure ({trickle: false})

Adjust the frequency of increments in milliseconds

NProgress.configure ({trickleSpeed: 200})

Turn off the spinner, which is on by default (the circle load icon in the upper right corner of the image above)

NProgress.configure ({showSpinner: false,})

Change the parent container

NProgress.configure ({parent:'#container'}); thank you for reading, the above is the content of "how to achieve the progress bar function when the page is loaded by vue".
