accessing page - enabling "sign in" button from login page

[SagarDoke]

suppose there are 2 files "1.html" and "login.html ".
from "1.html" i am opening second page "login.html ". "1.html" contain one button with value "signin". when i clicked on that button login form will be displayed and i disabled that button using document.form.b utton_name.disa bled=true;

but if login failed or cancel the login form, then how can i enabled that button again from "login.html ".

Post your code. Why are you disabling the button in the first place?

Hi,
<button name="SignIN" onClick="getSig nin()">Sign-In</button> to call the function "getSignin"

[CODE=javascript]function getSignin()
{
x = (1280 - 290)/2, y = (800 - 150)/2;

if (screen)
{
y = (screen.availHe ight - 150)/2;
x = (screen.availWi dth - 290)/2;
}

window.open("ht tp://localhost/ForumCreation/3.html","Login" , "width=290,heig ht=150,screenX= "+x+",screenY=" +y+",top="+y+", left="+x);
document.form12 .SignIN.disable d = true;
} [/CODE]

here, i am disabling that SignIN button. if not here then, how can i disabled that button from second place?

Right, I see you're opening a popup window. From the child window, use window.opener.d ocument.forms["form12"].elements["signIN"].disabled = false.

Sorry, but its not working. i thing I'm doing something wrong:

[HTML]<center>
User Name: <input type="text" name="name"><p> </p>
&nbsp; Password: <input type="password" name="psswd">
<p></p><input type="image" src="Classic2.G IF" onClick="getVal ue()">
<input type="image" src="Classic.gi f" onClick="exit() ">
</center>

<script language="JavaS cript">
function getValue()
{
var str1 = document.Forum. name.value;
var str2 = document.Forum. psswd.value;
var url = "4.jsp?name="+s tr1+"&psswd="+s tr2+"&status=lo gin";
window.open(url ,"_blank");
window.close();
}
function exit()
{
window.opener.d ocument.forms["form12"].elements["signIN"].disabled = false;
window.close();
}
</script>[/HTML]

When i clicked on cancel, then exit function called by that event. after that nothing is happened. i used jsp for database connection. when it called jsp file there i check that username and password. how can i check that username and password without opening that jsp page? there is no need of open that page. again if login failed how can i enabled sign-in button from first page? i am not getting that ajax for database connectivity.

window.opener should be in the popup window, but now you mention that you want to avoid opening the window and want to use Ajax. Is that correct?
