light1.js
function mySwitch() { var oBody = document.getElementById("myBody"); var oOnOff = document.getElementById("myOnOff"); var ogui = document.getElementById("gui"); if (oOnOff.src.match('bulbon')) { oOnOff.src = "http://www.runoob.com/images/pic_bulboff.gif"; oBody.style.backgroundColor = "black"; oBody.style.color = "white"; ogui.src = "https://timgsa.baidu.com/timg?image&quality=80&size=b9999_10000&sec=1509563443074&di=b1bbb3f5714a580e2211e281124636c2&imgtype=0&src=http%3A%2F%2Fpic15.nipic.com%2F20110709%2F7854247_221301558161_2.jpg"; } else { oOnOff.src = "http://www.runoob.com/images/pic_bulbon.gif"; oBody.style.backgroundColor = "white"; oBody.style.color = "black"; ogui.src = ""; } }
