JavaScript隨機產生顏色的方法這篇文章主要介紹了JavaScript隨機產生顏色的方法的相關資料,非常不錯，代碼簡單易懂，具有參考借鑒價值，需要的朋友可以參考下廢話不多說了直接給大家貼js代碼了，具體代碼如下所述：
?| 1234567891011121314151617181920212223242526272829303132333435363738 | <!DOCTYPE html><html><head lang="en"><meta charset="UTF-8"><title></title></head><body><button id="btn1">調用第一種</button><button id="bnt2">調用第二種</button><button id="btn3">調用第三種</button><script>var btn1=document.getElementById(‘btn1‘);btn1.onclick=function(){document.body.style.background=bg1()};var btn2=document.getElementById(‘bnt2‘);btn2.onclick=function(){document.body.style.background=bg2();};var btn3=document.getElementById(‘btn3‘);btn3.onclick=function(){document.body.style.background=bg3();};function bg1(){return ‘#‘+Math.floor(Math.random()*256).toString(10);}function bg2(){return ‘#‘+Math.floor(Math.random()*0xffffff).toString(16);}function bg3(){var r=Math.floor(Math.random()*256);var g=Math.floor(Math.random()*256);var b=Math.floor(Math.random()*256);return "rgb("+r+‘,‘+g+‘,‘+b+")";//所有方法的拼接都可以用ES6新特性`其他字串{$變數名}`替換}</script></body></html> |
