This article introduces several implementation methods of JavaScript random color code. For more information about JS random colors, see. JS random colors. For example, you can see that many tag connections are colorful. That's all we need. Start as follows: There are two methods in total.One is to prepare a set of beautiful candidate colors, and the other is to randomly generate colors.. Implementation 1 The Code is as follows: Var getRandomColor = function (){Return '#' +(Function (color ){R

This article will talk about how to use Javascript to obtain random colors. here we need to know that Javascript to obtain random colors is mainly used for easy display during plotting. I hope you can get help from this article. When creating a pie chart or a label cloud, we usually need many colors in two ways. One is to prepare a set of beautiful candidate colors, and the other is to randomly generate colors. When there are many or unknown numbers, I think the latter is the only way out. Googl

Method One:var function () { return ' # ' + (function(color) { return (color + = ' 0123456789abcdef ' [Math.floor (Math.random () *16)] ) (color.length = = 6)? Color:arguments.callee (color); }) (');}Randomly generated 6 characters and then strung together, the closure calls itself with the ternary operator to make the program become introverted.Method Two:var function () { return (function(m,s,c) { return (c? Arguments.callee (m,

JS random color has a lot of places to use: For example, we see a lot of label connections are colorful. That's the one that needs to be here. Here's the start: There are two ways of thinking. one is to prepare a beautiful set of candidate colors, the second is to generate color randomly . Achieve 1 Copy Code code as follows: var getrandomcolor = function () { Return ' # ' + (function (color) { return (color + = ' 0123456789abcdef
