Q307 Is there a way to have a Pop Up window ask for a name and
password and then send this information to a cgi script ?


In the main document :


<SCRIPT LANGUAGE="JavaScript"><!--
function windowOpen() {
    var myWindow=window.open('popup.html','windowRef','width=200,height=200');
    myWindow.location.href = 'popup.html';
    if (!myWindow.opener)
        myWindow.opener = self;
}

windowOpen();
//--></SCRIPT>

And in the popup.html document

<SCRIPT LANGUAGE="JavaScript"><!--
function returnDetails() {
    opener.location.href = 'whatever.cgi?login=' + escape(document.myForm.loginname.value) + '&password=' + escape(document.myForm.loginpassword.value);
    setTimeout('window.close()',500);
}
//--></SCRIPT>

<FORM NAME="myForm">
Name: <INPUT TYPE="TEXT" NAME="loginname">
Password: <INPUT TYPE="PASSWORD" NAME="loginpassword">
<INPUT TYPE="BUTTON" VALUE="ENTER" onClick="returnDetails()">
</FORM>

Q280 How can I capture a login name and password in a popup window and
then pass it onto the next page?

in the initial.html:

<script language="JavaScript"><!--
var loginname = '';
var loginpassword = '';

function windowOpen() {
    var myWindow=window.open('popup.html','windowRef','width=200,height=200');
    myWindow.location.href = 'popup.html';
    if (!myWindow.opener)
        myWindow.opener = self;
}

function go(url) {
    location.href = url + '?' + loginname + '&' + loginpassword;
}

windowOpen();
//--></script>
<a href="javascript:go('nextpage.html')">go to next page</a>

in the popup.html:

<script language="JavaScript"><!--
function returnDetails() {
    opener.loginname = document.myForm.loginname.value;
    opener.loginpassword = document.myForm.loginpassword.value;
    self.close();
}
//--></script>
<form name="myForm">
Name: <input type="text" name="loginname">
Password: <input type="password" name="loginpassword">
<input type="button" value="enter" onClick="returnDetails()">
</form>

in the nextpage.html:

<script language="JavaScript"><!--
var start = location.search.indexOf('?');
var end   = location.search.indexOf('&');
var loginname = location.search.substring(start+1,end);
var loginpassword = location.search.substring(end+1);

alert('Name = ' + loginname + '\n' + 'Password = ' + loginpassword);
//--></script>

Q240 Is it possible to dynamically alter the size of a window after it has been created?

The following works in Netscape Navigator 4 only:

<SCRIPT LANGUAGE="JavaScript"><!--
if (window.screen && document.layers) {
    window.moveTo(0,0);
    window.outerHeight = screen.availHeight;
    window.outerWidth = screen.availWidth;
}
//--></SCRIPT>

The following works in both Netscape Navigator 4 and Internet Explorer 4:

<SCRIPT LANGUAGE="JavaScript"><!--
window.resizeTo(655,450);
//--></SCRIPT>

They don't however work the same. Netscape Navigator 4 resizes the window so that the document pane is 655x450, whereas Internet Explorer resizes the window to 655x450.
