问题
This seemed so trivial when I started off with it! My objective is this:
- When user clicks on a button, open up a form in a new window.
- Once the form is submitted, close the popup and return to the original page. The reverse order is fine too - i.e., I am okay if the popup is closed and then the form submits.
Here's how I'm doing this:
<form action="/system/wpacert" method="post" enctype="multipart/form-data" onsubmit="return closeSelf()" name="certform">
<div>Certificate 1: <input type="file" name="cert1"/></div>
<div>Certificate 2: <input type="file" name="cert2"/></div>
<div>Certificate 3: <input type="file" name="cert3"/></div>
<div><input type="submit" value="Upload"/></div>
</form>
and the Javascript looks like this:
<script type="text/javascript">
function closeSelf(){
self.close();
return true;
}
</script>
This seems to work fine on IE8 and Chrome; but Firefox refuses to submit the form; it just closes the popup. What might I be doing wrong?
EDIT:
Had forgotten to post the code the opens the popup. Here it is:
<div><input type="submit" value="Upload Certificates" onclick="popupUploadForm()"/>
And the corresponding javascript:
function popupUploadForm(){
var newWindow = window.open('/cert.html', 'name', 'height=500,width=600');
}

I have executed the code in my machine its working for IE and FF also.
function closeSelf(){
// do something
if(condition satisfied){
alert("conditions satisfied, submiting the form.");
document.forms['certform'].submit();
window.close();
}else{
alert("conditions not satisfied, returning to form");
}
}
<form action="/system/wpacert" method="post" enctype="multipart/form-data" name="certform">
<div>Certificate 1: <input type="file" name="cert1"/></div>
<div>Certificate 2: <input type="file" name="cert2"/></div>
<div>Certificate 3: <input type="file" name="cert3"/></div>
// change the submit button to normal button
<div><input type="button" value="Upload" onclick="closeSelf();"/></div>
</form>

I know this is an old question, but I stumbled across it when I was having a similar issue, and just wanted to share how I ended achieving the results you requested so future people can pick what works best for their situation.
First, I utilize the onsubmit event in the form, and pass this to the function to make it easier to deal with this particular form.
<form action="/system/wpacert" onsubmit="return closeSelf(this);" method="post" enctype="multipart/form-data" name="certform">
<div>Certificate 1: <input type="file" name="cert1"/></div>
<div>Certificate 2: <input type="file" name="cert2"/></div>
<div>Certificate 3: <input type="file" name="cert3"/></div>
<div><input type="submit" value="Upload"/></div>
</form>
In our function, we'll submit the form data, and then we'll close the window. This will allow it to submit the data, and once it's done, then it'll close the window and return you to your original window.
<script type="text/javascript">
function closeSelf (f) {
f.submit();
window.close();
}
</script>
Hope this helps someone out. Enjoy!
Option 2: This option will let you submit via AJAX, and if it's successful, it'll close the window. This prevents windows from closing prior to the data being submitted. Credits to http://jquery.malsup.com/form/ for their work on the jQuery Form Plugin
First, remove your onsubmit/onclick events from the form/submit button. Place an ID on the form so AJAX can find it.
<form action="/system/wpacert" method="post" enctype="multipart/form-data" id="certform">
<div>Certificate 1: <input type="file" name="cert1"/></div>
<div>Certificate 2: <input type="file" name="cert2"/></div>
<div>Certificate 3: <input type="file" name="cert3"/></div>
<div><input type="submit" value="Upload"/></div>
</form>
Second, you'll want to throw this script at the bottom, don't forget to reference the plugin. If the form submission is successful, it'll close the window.
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script>
<script src="http://malsup.github.com/jquery.form.js"></script>
<script>
$(document).ready(function () {
$('#certform').ajaxForm(function () {
window.close();
});
});
</script>

Here's how I ended up doing this:
<div id="divform">
<form action="/system/wpacert" method="post" enctype="multipart/form-data" name="certform">
<div>Certificate 1: <input type="file" name="cert1"/></div>
<div>Certificate 2: <input type="file" name="cert2"/></div>
<div><input type="button" value="Upload" onclick="closeSelf();"/></div>
</form>
</div>
<div id="closelink" style="display:none">
<a href="javascript:window.close()">Click Here to Close this Page</a>
</div>
function closeSelf(){
document.forms['certform'].submit();
hide(document.getElementById('divform'));
unHide(document.getElementById('closelink'));
}
Where hide() and unhide() set the style.display to 'none' and 'block' respectively.
Not exactly what I had in mind, but this will have to do for the time being. Works on IE, Safari, FF and Chrome.

Try like this as well
covertPostSub("/xyz/test.jsp","?param1=param1¶m2=param2","_self","true");
covertPostSub("/xyz/test.jsp","?param1=param1¶m2=param2","_blank","true");
var convPop = null;
function covertPostSub(action,paramsTosend,targetIframe,isWindow){
var Popup = null;
var form = document.createElement("form");
form.setAttribute("method", "POST");
form.setAttribute("id","TheForm");
form.setAttribute("action", action);
form.setAttribute("target", targetIframe);
var params = paramsTosend;
params = params.substring(1, params.length);
params = params.split("&");
for(var key=0; key<params.length; key++) {
var sa = params[key];
sa = sa.split("=");
var xs = (sa[1]);
if(params.hasOwnProperty(key)) {
var hiddenField = document.createElement("input");
hiddenField.setAttribute("type", "hidden");
hiddenField.setAttribute("name", sa[0]);
hiddenField.setAttribute("value",xs);
form.appendChild(hiddenField);
}
}
document.body.appendChild(form);
form.style.display = "none";
if(isWindow){
window.open('', "formpopup","width=900,height=590,toolbar=no,scrollbars=yes,resizable=no,location=0,directories=0,status=1,menubar=0,left=60,top=60");
form.target = 'formpopup';
form.submit();
}else{
form.submit();
}
}
