用JS编写输入用户名和密码,第1张

var name=document.getElementById("username")var pwd=document.getElementById("usepwd")/*按钮点击事件*/if(name.value!=admin &&ped.value!=123456){alert("用户名或者密码错误")}else{alert("用户登陆成功")}---------------纯手打，望采纳

$(function(){

var name1=getCookie('name1')

var name2=getCookie('name2')

var name5=getCookie('name5')

dataForm="name1="+name1+"&name2="+name2+"&name5="+name5

$.ajax({

type:"POST",

url:"login.php",

data:dataForm,

success:function(msg){

var str = eval('('+msg+')')

// 判断

}

})

})

function getCookie(c_name){

if(document.cookie.length>0){

c_start=document.cookie.indexOf(c_name + "=")

if(c_start!=-1){

c_start=c_start + c_name.length+1

c_end=document.cookie.indexOf("",c_start)

if(c_end==-1) c_end=document.cookie.length

return unescape(document.cookie.substring(c_start,c_end))

}

}

return ""

}

</script>

function login()

{

var username=document.getElementById("userName")

var password=document.getElementById("password")

if(username.value=="admin"&&password.value="123456")

{

window.location.href="success.html"

}

}

为登录按钮注册onclick=“login()”
