1.请问如何看到网页上用javascript做的密码密码登陆密码源代码？
2.求不用数据库简单的PHP密码验证源码
3.jsp登陆界面源代码
4.求html登陆界面详细代码 要可以登陆，不用数据库保存，验证源码验证源码只要验证账号密码正确，网页网页官网前台源码就连接到另外一个.html的密码密码界
请问如何看到网页上用javascript做的登陆密码源代码？
一个简单的
账号是：username
密码是：password
<script language="javascript">
<!--//
/*This Script allows people to enter by using a form that asks for a
UserID and Password*/
function pasuser(form) {
if (form.id.value=="username") {
if (form.pass.value=="password") {
location="page2.html"
} else {
alert("Invalid Password")
}
} else { alert("Invalid UserID")
}
}
//-->
</script>
<center>
<table bgcolor="white" cellpadding="" border="1">
<tr><td colspan="2"><center><h1><i><b>Login
Area</b></i></h1></center></td></tr>
<tr><td><h1><i><b>UserID:</b></i></h1></td><td><form name="login"><input
name="id" type="text"></td></tr>
<tr><td><h1><i><b>Password:</b></i></h1></td><td><input name="pass"
type="password"></td></tr>
<tr><td><center><input type="button" value="Login"
onClick="pasuser(this.form)"></center></td><td><center><br><input
type="Reset"></form></td></tr></table></center>
求不用数据库简单的PHP密码验证源码
不用数据将密码直接写到源程序当中是很危险的只要查看源程序就知道密码
<form action="?" method="post">
用户名:<input type="text" name="username"/></br>
密 码:<input type="password" name="pwd" /></br>
<input type="submit" value="登入" /></br>
</form>
<?php
$username='admin';
$pwd='';
if(isset($_POST['username'])){
if( $_POST['username']==$username && $_POST['pwd']==$pwd ){
echo "登入成功！";
}else{
$_POST['pwd']==$pwd ){
echo "登入失败！验证源码验证源码vcsource源码怎么设置";
}
}
>以上就是网页网页庄家追踪指标源码了，这种要每次重新登入
密码也不安全，密码密码不过有办法
你重新创建一个php
<?验证源码验证源码php
echo md5("");//你要设置的密码
>进去这个页面他会给出一个md5数据摘要
复制到$pwd
然后把密码对比改为
md5($_POST["pwd"])==$pwd
这种的话别人即使看到源码也不知道密码是什么
