Hi guys!
I'm studying Java.
I have an project that make a login using JavaScript and
XML.
That means, file
XML contains username and password.
Here is the file that i have created:
- PHP: Select all
<script language="javascript">
function login()
{
if (document.frmlogin.login_username.value == "")
{
alert("User name is not blank");
return;
}
else if(document.frmlogin.login_pass.value == "")
{
alert("Password is not blank");
return;
}
else
{
var xmlDoc= new ActiveXObject("Msxml2.DomDocument.4.0");
xmlDoc.load("xml/user.xml");
var ktra=true;
for(var i=0;i<2;i++)
{
var xml=xmlDoc.childNodes(1).childNodes(1).childNodes(i);
var name=xml.childNodes(0);
var pass=xml.childNodes(1);
if(name.text==frmlogin.login_username.value &&pass.text==frmlogin.login_pass.value)
{
ktra=true;
break;
}
else
{
ktra=false;
}
}
if(ktra==true)
{
alert("Login Successfully !!!");
window.location="indexAdmin.htm";
}
else
{
alert("Login Failed !!!");
}
}
}
</script>
