15 different appearance clock js plug-ins based on canvas

Brief Tutorial

CanvasClock is a pure js clock plug-in based on Canvas. This js clock plug-in can generate clocks with 15 different appearances by configuring parameters. It is made using pure js and does not use any css code or external dependencies.

Usage method

Introduce the canvas_clock.js file into the page.

<script type="text/javascript" src="js/canvas_clock.js"></script>

HTML structure

Use an HTML5 element as the container for the clock.

<canvas id="demo" width="200px" height="200px"></canvas>

Initialization plug-in

You can create a default clock through the following method.

clock = {};

You can also pass in configuration parameters when creating.

clock = {
   
  // shows indicators
  "indicate": true/false,
 
  // color of the indicaters
  "indicate_color": "#aabbcc",
 
  // color of the seconds dial
  "dial1_color": "#aabbcc",
 
  // color of the minutes dial
  "dial2_color": "#aabbcc",
 
  // color of the hour dial
  "dial3_color": "#aabbcc",
 
  // shows the time as well using text
  "time_add": 1/2/3/4,
 
  // the color of the text time
  "time_add_color": "#aabbcc",
 
  // use 24 hour notation
  "time_24h": true/false,
 
  // modify the time by adding or subtracting seconds to the time
  "timeoffset":0,
 
  // show the date as well using text
  "date_add": 1/2/3/4/5,
 
  // the color of the date text
  "date_add_color": "#aabbcc",
 
  // the background color
  "bg_color":"#fff",
 
  // the opacity of the background image if shown
  "bg_opacity": 0.0-1.0,
 
};

You can then get a context reference to the element by its ID, and then render the clock using the constructor of the clock that specifies the appearance. For example:

context = document.getElementById('clock1_').getContext('2d')
clock_conti(context, 200, object);

The following are available clocks:

• clock_conti

• clock_digital

• clock_norm

• clock_follow

• clock_circles

• clock_grow

• clock_dots

• clock_num

• clock_random

• clock_digitalran

• clock_bars

• clock_planets

• clock_roulette

• clock_reverse

• clock_binary
