js代码：
function mySwitch() { var oBody= document.getElementById("myBody"); var oOnoff = document.getElementById("myOnOff"); var oUname = document.getElementById("uname"); var oError = document.getElementById("error_box"); var oUpass = document.getElementById("upass"); var oUpass1 = document.getElementById("upass1"); oError.innerHTML = "<br>"; var isError = true; if(oOnoff.src.match("bulbon")){ oOnoff.src="http://www.runoob.com/images/pic_bulboff.gif"; oBody.style.background="darkgray"; oBody.style.color="white"; }else { oOnoff.src="http://www.runoob.com/images/pic_bulbon.gif"; oBody.style.background="white"; oBody.style.color="gray"; } if (oUname.value.length < 6 || oUname.value.length > 20) { oError.innerHTML = "用户名要6-20位"; isError = false; return; }else if(oUname.value.charCodeAt(0)>=48 &&(oUname.value.charCodeAt(0)<=57)){ oError.innerHTML="首位不能为数字"; return; }else for (var i=0;i<oUname.value.length;i++){ if((oUname.value.charCodeAt(i)<48)||(oUname.value.charCodeAt(i)>57)&&(oUname.value.charCodeAt(i)<58)&&(oUname.value.charCodeAt(i)>97)){ oError.innerHTML="只能为数字和字母"; return; }} if (oUpass.value.length < 6 || oUpass.value.length > 20) { oError.innerHTML = "密码要6-20位"; isError = false; return; }else if(oUname.value!=oUpass1.value) { oError.innerHTML = "设置密码和验证密码不一致"; return; } }
css代码如下：
h2 { font-family: 宋体; font-size: 28px; text-align: center; background: #cccccc; margin-top: auto; height: 30px; width: 500px; } .box { border: 1px solid #000000; height: 330px; width: 500px; float: left; margin: 30px; margin-left: 30%; } .input_box { text-align: center; height: 30px; width: 500px; } .input_button { font-size: 22px; width: 340px; height: 30px; align-self: center; margin-bottom: auto; margin-left: 40%;} div.desc { text-align: center; padding: 5px }
运行结果如下：
