<head>
<title>Add Qualification</title>
<script type="text/javascript">

alert("Please enter a qualification name!");
return false;
}
}

Hey guys, Been searching on google for two days now, without a valid answer. I'm NEW to javascript, so I need some good help on this haha. I am using the following little piece of code to open a popup window: Code: <SCRIPT LANGUAGE='JAVASCRIPT' TYPE='TEXT/JAVASCRIPT'>
<!--
var win=null;
function NewWindow(mypage,myname,w,h,pos,infocus){
if(pos=="random"){myleft=(screen.width)?Math.floor(Math.random()*(screen.width-w)):100;mytop=(screen.height)?Math.floor(Math.random()*((screen.height-h)-75)):100;}

win.focus();}
// -->
</script>
The actual link to open the popup is like this: Code: <a href="javascript:NewWindow('upload.php','popup','550','252','center','front');">Open the popup</a>
What I am opening is, an upload page to upload an image (PHP / AJAX). Once the upload is complete and I close the window, I need the parent window (the index page which the link to open the popup is on) to be refreshed, so you can see that the file has been successfully uploaded. Does anyone have a clue how I would fix this? If I need to use another code to open the popup, that's fine, I just need help on how to fix this, since I haven't been able to find the answer myself. Thanks in advance! In my application I want user to take an "Exit Survey"(Independent website) when he is leaving the application. As name explains, It should happen only when user closes current browser tab or browser window. Its possible using JavaScript OnUnload event. But the problem is that this event occurs on 1. close of browser tab 2. close of browser window 3. click of any internal page link(i.e anchors and form buttons) 4. click of browser's Refresh button 5. click of browser's Back/Forward button I have handled first 3 cases but not able to detect Refresh and Back/Forward button click. Has anybody of you implemented such functionality?? Thanks in advance!!! Hi, I have parent page with 10 child window and i want to close all child window when click on close session button on parent but first i need to check whether any child window open or not after that action should be done for close the child window. Hello all, I have a form that submits a POST request when data is submitted. A Servlet then processes this POST request and a JavaBean is used to make some calculations. The HTML response is not generated within the Servlet but instead I forward the request to a JSP to generate the response. - This all works fine, thankfully. However, I am stupidly suck trying to validate the form on the client side with a JavaScript function before the form is submitted. Here is my index.jps: Code: <%--

Regardless of whether incorrect input is given, the data is still POSTed to the server and calculated on or a Server Side error is given. Am I correct in calling the function onClick? The validation essentially needs to be so that: - Student field contains a string - Score1, Score2, Score3 and Score 4 contain a number between 0 and 100 Any help is most appreciated, Cheers, Beetle. Hi, I'm kinda hoping this is possible but haven't found any reference to it... I have a parent page that opens a popup on click that launches a sidebar navigation on the right of the screen and resizes the parent page. What I am wanting to do is create a second popup (approx 250px high) that opens below the navigation (which is only around 600px high) but I have noticed that even when you have no status bar in the popup windows, they can still end up overlapping because of additional tools or plugins that the viewer has in their browser. Is there any way to get the popups to butt up against each other instead of overlapping? More like a relative popup? Any assistance would be appreciated. :-) Hi, I have the below code: Code: <script type="text/javascript">
function loadQuickMessageCheck(File,ID){
var xmlhttp;
if (window.XMLHttpRequest) {
xmlhttp=new XMLHttpRequest();
}
else {
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if (xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById(ID).innerHTML=xmlhttp.responseText;
eucalyptus = setInterval(function(){loadQuickMessageCheck(File,ID)},20000);
}
}
xmlhttp.open("POST",File,true);
xmlhttp.send();
}
</script>
But I am overloading the server and crashing it. I've googled the issue and have found people with similar problems who talk about the need to cancel the last refresh request before they send the next refresh. I even found this nice piece of code which worked for someone else. Quote: try{window.clearTimeout(tRefresh)} catch(err) {} tRefresh = setInterval(setContext, varInterval*60*1000); } I am not sure if this is the solution that I am looking for but if it is all my attempts at applying this code has been a bit of a disaster. Hi! I'm new to this, so please bare with me. My terminology may not be up to par. Here's the deal: - I have a button on my Flash site that opens an HTML page in a popup window. In Flash, I open the new window using Actiosnscript 2.0: Code: on (release) {
getURL("example1.html", "_blank");
}
- Within the popup window are links to other HTML pages. They all open in the same window. I've been using the following to create the links in Dreamweaver: Code: onClick="MM_goToURL('parent','example2.html')"
- On each page, I have a "Return to Main Menu" button that should close the popup window. To do this, I have been using: Code: onClick="window.close()" - The problem is that it works differently in each browser, and I can't even get it to consistently close the window in most browsers: Internet Explorer = popup message appears, asking "Are you sure you want to close this window?" or something similar; window closes after clicking "Yes." Safari = Only closes if I'm on the original HTML page. If I click on any of the other links (note that these all open in the same window), those pages' "Return to Main Menu" buttons cease to work. However, if I keep clicking "Back" until I get to the original page, it closes. Opera = Button actually works for each page. Firefox & Chrome = Does not close the window at all. I looked into it and saw that others have used a window.opener to solve similar issues. But, since my popup window is opened using Flash/AS2, I need to find a way around it. I've tried preceding "window.close()" with "window.opener=null" (i.e. - onClick="window.opener=null; window.close()"), but I don't think I'm doing it right because it still doesn't work. I've also seen others use codes that involve functions and variables, but it is beyond my current coding knowledge to implement this. Like I said, I'm sort of new at this. Any advice would be greatly appreciated. Thank you. - PW I have a web site application written in VB.net and asp. The main page uses JavaScript to load a popup page that performs multiple tasks. The main page accepts a variety of incoming messages, only SOME of which need to be passed to this popup page for processing. I found an ugly way to pass the message to the popup by placing it in a Session variable. Now I need to cause it to be handled. I see two possibilities, and I do not have a clue how to implement either. Either one would be great: 1. In the main page, trigger a subroutine in the popup, using JavaScript. OR 2. In the popup, establish a trigger any time that Session variable changes. Hi Guys, I have a pop up that opens for a second then hides behind main window for some reason Code: <img src="../../../print_this_page.gif" title="Click To Print This Page" width="64" height="64" onmousedown="MM_openBrWindow('{ads_print_href}?item_id={item_id}','printnew','scrollbars=yes,width=950,height=800')" />
Any ideas what i can add to the code so it stays in top. Works on firefox. Issue is with IE8 Thanks Code: // Form submission
$('#contact-form').submit(function()
{
// Hide any message
$('span#contact-msg').css('opacity', 0);
// Build data string
var fields = [ 'name', 'email', 'message' ];
var data = 'ajax=1';
for (var i = 0; i < fields.length; i++)
data += '&' + fields[i] + '=' + encodeURI($('#' + fields[i]).val());
// Submit
$.ajax( { url : $('#contact-msg').attr('action'),
dataType: 'json',
data: data,
type: 'POST',
success: function(data)
{
if (data.sent == true)
{
$('span#contact-msg').html('Thanks for the message. I will get back to you as soon as possible.');
$('#send').css('backgroundPosition', '-207px -168px');
$('#send').attr('disabled', 'disabled');
}
else
$('span#contact-msg').html(data.error);
$('span#contact-msg').animate( { opacity: 1 }, 400);
}
});
return false;
});

Folks I'm using the code below to create a pop-up search box that finds text strings on a contents page. The contents page contains a list of hyperlinks each of which opens a PDF document in the same window. The search box does exactly what it's intended to do, but the problem is this: if the user clicks on "Find next" or "Find previous" once the PDF document is open, an error occurs; the same error occurs if the user then navigates back to the contents page and clicks on "Find next" or "Find previous". I'm thinking the solution must be to get the search box to close as soon as the PDF document opens, but how do I achieve this? Thanks Remster Code: <html>

The left-hand (main) menu for my website (www.displaycentre.co.uk) is extremely slow on IE8 on some PCs yet fine on others. No problems with other browsers at all. I know that the menu is huge but cannot understand why the speed is fine on some (even low spec) PCs and yet it is painfully slow on others. It is slow on all of my work PCs (some with 512Mb RAM others have 2GB!) and also my PC at home (which is brand new this weekend, 2Gb RAM and only Windows XP + all updates loaded so far). Any body out there got any ideas? My developer is simply putting it down to the way in which IE8 copes with such huge menus? Thanks in anticipation. Chris First, I will state that I am totally inexperienced in JavaScript. I have a web site application written in VB.net and asp. The main page uses JavaScript to load a popup page that performs multiple tasks. The main page accepts a variety of incoming messages, only SOME of which need to be passed to this popup page for processing. I found an ugly way to pass the message to the popup by placing it in a Session variable. Now I need to cause it to be handled.
