login form looking for help - please
« on: 02-21-2012, 03:46:49 »
   
Hello Im looking for help with my login form...So far I have coded that if I put in the correct password and username then I will getinto my site. I would like to have something whereby if I put in 3 failed attempts I get a message each time telling me how many attempts I have left and then no access.
After every failed attempt I want the textbox to clear aswel so i can enter in the next attempt......Thanks guys

All help would be very helpful...I have tried this for a few days now with success ......

here is my cose so far

<script language="javascript">

function passuser(form)
{
if (form.user.value=="tony" &&form.password.value=="hello")
{
window.alert("Hello tony")
location='http://www.google.com'

}
}
</script>
</head>

<body><center><br />



<form action="name" method="get">
<table width="300" height="200" border="1" cellpadding="5"cellspacing="5">
<tr>
<th colspan="2" scope="col"bgcolor="#6699FF"><center>LOGIN FORM</center></th>
</tr>
<tr>
<td width="120" align="center"> User Name</td>
<td width="140"><label>
<input type="text" name="user" id="user" />
</label></td>
</tr>
<tr>
<td align="center">Password</td>
<td><label>
<input type="password" name="password" id="password" />
</label></td>
</tr>
<tr>
<td align="center"><label>
<input type="reset" name="cmdClear" id="cmdClear" value="Reset" />
</label></td>
<td align="center"><label>
<input type="submit" name="enter" id="log" value="Login" onclick="passuser(this.form)" />

Hi and thnks for your reply. I got the login form working ok but when I put a wrong password into the form my form page shuts down when viewing it on the net. The process works fine when testing it out on dreamweaver. any ideas? am i missing some code. All help would be great thank you. Here is my code now up to date:

<script language="javascript">
var counter = 2
function passuser(form)
{
if (form.user.value=="john" &&form.password.value=="hello")
{
 window.alert("Hello there")
 location='http://www.google.com'

}
  else if (counter <=0)
{
   window.alert("Access Denied")
   window.close()

 
}
else
 {
 window.alert("Username or Password is incorrect - You have " +counter+ " tries left")
     counter = counter - 1
return false;
  }
}






</script>
</head>

<body><center><br />


   
<form action="name" method="get">
  <table width="300" height="200" border="1" cellpadding="5"cellspacing="5">
    <tr>
      <th colspan="2"  scope="col"bgcolor="#6699FF"><center>LOGIN FORM</center></th>
    </tr>
    <tr>
      <td width="120" align="center"> User Name</td>
      <td width="140"><label>
        <input type="text" name="user" id="user" onFocus="this.value=''" value="" />
      </label></td>
    </tr>
    <tr>
      <td align="center">Password</td>
      <td><label>
        <input type="password" name="password" id="password" onFocus="this.value=''" value="" />
      </label></td>
    </tr>
    <tr>
      <td align="center"><label>
        <input type="reset" name="cmdClear" id="cmdClear" value="Reset" />
      </label></td>
      <td align="center"><label>
        <input type="submit" name="enter" id="log" value="Login" onclick="passuser(this.form)" />
      </label></td>
    </tr>
  </table>
</form>
</center>
</body>

hey I got the issue with the code.You did a mistake.Do modify the code with this line
<form action="form.html">

check your code it must be like above I wrote.I checked  manually you put form action ="name" which is wrong .In action ,we use to put the url of page where it will be redirected after the page will be submitted .replace your code with above mentioned one and you will be get the desired results

also i strongly recommend you please visit w3schools for the syntax of programming code .you have mistaken in  few more lines and learn javascript from there
to open a new site the code must looks like window.open("http://www.google.com")
