Redirection using servlet not working - javascript

I was trying to redirect after an alert message in servlet something like this :
out.println("<script>alert('Group Request Invitation Canceled');document.location='individualdetailstoadd.jsp?personid=''"+idperson+"'</script>");
But its not working.Though if I remove the redirection,the alert message is displayed .
What can be the reason ?Please help

You do not need the single quotes before the double quotes.
Try
out.println("<script>alert('Group Request Invitation Canceled');document.location='individualdetailstoadd.jsp?personid="+idperson+"'</script>");
The generated HTML will be along the following lines:
<!DOCTYPE HTML>
<html>
<body>
<script>
alert('Group Request Invitation Canceled');
document.location='individualdetailstoadd.jsp?personid=5'</script>
</body>
</html>
I tested this in my browser and it redirects successfully.

jQuery ajax plugin get entered value

I am using jQuery autocomplete plugin to get values from database using this plugin. As per demo I made my code like this
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<script src="http://code.jquery.com/jquery-2.1.0.min.js"></script>
<script src="js/jquery.autocomplete.js"></script>
<link rel="stylesheet" href="styles.css">
<script>
jQuery(document).ready(function() {
jQuery('#autocomplete').autocomplete({
serviceUrl: 'ajax.php',
});
});
</script>
</head>
<body>
<input type="text" id="autocomplete">
</body>
</html>
Now when I am doing any search. Then in console tab I can see the ajax request like this
XHR finished loading: GET "http://localhost/ajax.php?query=united
additionally it is showing one error in console tab like
Uncaught SyntaxError: Unexpected token < in jquery-2.1.0-min.js:4
Now to get the value of query string in ajax.php I did like this
$value = $_POST['query];
echo $value;
But it is not showing any value. So can someone tell me how to get the input entered values in the ajax.php file? Any help and suggestions will be really appreciable. Thanks
You are using Google Chrome, aren't you?
It would be helpful to see what data is actually transfered...
Try to hit F12, open the "Network" tab, click on the item that shows up when the AJAX request is made, and check the output in the "Response" sub tab.
My assumption: You're facing some syntax error in your PHP file that outputs HTML tags as part of an error message.
BTW: Your PHP code contains a syntax error, the ' after index "query" on line 1 is missing...

Disable Firefox 7.0.1 javascript in url security

It seems that firefox has disabled the ability to run a javascript: from the URL...does anybody know of a way around this?
My site requires an id pulled from the html of another site when that user is logged in. Instead of having the user search the 'view source' page I devised a javascript link to scrape it and send it to the site automagically, but it doesn't work on firefox.
The actual code I'm trying to run:
javascript:void(window.open('http://mysite.com/login?u=' + encodeURIComponent(window.location) + '&s=' + SessionId));
Scrapping the session id from the game in order to pull data for the player, nothing like a facebook hack or anything malicious.
I'd have to see your code but you really shouldn't have a problem doing what you're attempting to do. If you need another option though I have one you could try. If the content of the page you're scraping is within the same domain as your other site you could use an iframe to get the ID.
Here's some code to consider:
Your data collecting page:
<!DOCTYPE html>
<html>
<head>
<title>Disable Firefox 7.0.1 javascript in url security</title>
<script type="text/javascript">
function scrapeData() {
var frame = document.getElementById("otherPage");
var otherPagesObj = frame.contentWindow.document.getElementById("otherContent");
alert("Your data: " + otherPagesObj.innerHTML);
}
</script>
</head>
<body onload="scrapeData();">
<iframe id="otherPage" src="otherpage.htm" width="1" height="1" />
</body>
​</html>​​​​​​​​​​​​​​​​​​​​​​​​
Your page to be scraped (otherpage.htm):
<!DOCTYPE html>
<html>
<head>
<title>Other Page - Disable Firefox 7.0.1 javascript in url security</title>
</head>
<body>
<div id="otherContent">1</div>
</body>
​</html>​​​​​​​​​​​​​​​​​​​​​​​​
Using the above code you can see "1" alerted from the div of another page. This is a simple, cross-browser compatible option for what you're attempting to do.
Hope this helps.

"Message send" confirmation popup with PHP and JS

I am just started with PHP and have a rather simple problem I can't seem to figure out. I have set up a basic PHP script with will send me the content from my sites contact page. The script itself is fine - and so is the validator. Now what I am trying to achieve is getting a simple popup (similar to an alert function in javascript). Here is my try:
if ($valid) {
//*isUTF8($subject);
//*isUTF8($formcontent);
sendMail();
$body = $successMarkup . $backMarkup;
$title = "Form sent";
#header("location:formsent.php");
} else {
$body = $errorMarkup . $errorMarkupEnd . $backMarkup;
$title = "Form errors";
}
The file formsent.php I am refering to here only includes basic html markup as well as an javascript alert which is executed as soon as you open the page:
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Contact Success</title>
</head>
<body>
<script language="Javascript">
<!--
alert ("Thank you for your message! I will come back to you as soon as possible!")
//-->
</script>
</body>
</html>
Here my question:
After I send the filled out contactsheet via the send button I get a popup with the message shown above - BUT to do so it leaves the actual page I am on and shows me only a white screen.
How can I get that popup message implemented without leaving the page I am on?
Try using this one: http://jquery.malsup.com/form/ with jQuery to make an Ajax form submit simple.
The examples, shown on that page are quite enough to implement your type of a story.
just put:
<script>
$(document).ready(function(){
$('form#form_id').ajaxForm(
function(data){
alert(data);
}
)
})
</script>
And so everything you need to do in your sendmail script is to echo the needed message, no redirecting required.
header("Location: <url>") results in a proper redirect. You need to use Ajax here to send the data (when the user submits it), receive the contents of the popup box and then display it.

Facebook Like Button Dislikes My Code

I've been trying to implement a Facebook Like button on my blog like this:
$("#fblike").append(" <iframe src='http://www.facebook.com/plugins/like.php?app_id=217624258276389&" + window.location.href + "&send=false&layout=box_count&width=50&show_faces=false&action=like&colorscheme=light&font&height=60' scrolling='no' frameborder='0' style='border:none; overflow:hidden; width:50px; height:60px;' allowTransparency='true'></iframe>");
And adding this to the <head> of my HTML source file:
<script type="text/javascript" src="http://connect.facebook.net/en_US/all.js"></script>
The problem is that when I try to test the Like button it shows 1 instead of 0 and a second later goes back to 0. Nothing changed at my Facebook profile neither. What's wrong and how to correct this?
PS: I'm running this on a localhost server, in my case http://nathan-camposs-macbook-pro.local/~Nathan
I think the events go something like:
You click the button.
Javascript sends the like request to FB.
Facebook tries to access your page ("localhost").
It can't access it so the request is denied.
UPDATE:-
I noticed that your src attribute starts: 'http://www.facebook.com/plugins/like.php?app_id=217624258276389&" + window.location.href + "&
i think it should be: 'http://www.facebook.com/plugins/like.php?app_id=217624258276389&href=" + window.location.href + "&
notice the href=
I've had problems testing the like on sites using temp urls - Facebook doesn't like it when the associated app_id value is not related to the url of the page you're trying to like. But I could be wrong. If you temporarily expand the width to something beyond 50 (like 300-350), there should be an "error" link that pops up that will give you some more valuable information...
If you use fbml then you will not need the application ID. Using fbml you can configure several things. I think you already have a look at-
http://developers.facebook.com/docs/reference/plugins/like/
You can try the following code
<head>
<script type="text/javascript" src="http://connect.facebook.net/en_US/all.js"></script>
</head>
Then in the body
<div id="fb-root"></div>
<fb:like href="http://yoururl" send="true" width="450" show_faces="true" font="">
</fb:like>

JavaScript access parent window from popup windows

I am trying to code this for hours and still couldn't do it. It keep tell me "Permission Denied".
Here is what I am trying to accomplish. This pretty hard to explain please follow the example below.
For example. domain111.com and domain222.com.
When I am on domain111.com i click on the popup link , it will pop-up the domain111.com/popup.html then it redirect me to domain222.com. On this domain222.com it will redirect to couple pages before it redirect back to domain111.com with the result. I want to send the result from domain111.com to domain111.com.
The process is like below.
Domain111-popup to-->Domain111-redirect-->Domain222-redirect xxx Domain222 pages then redirect to-->-Domain111---SEND to parent window->Domain11
Here is my code.
File name 1.hml on domain111.com
<script type="text/javascript">
function IamParent() {
alert('I am the parent of this window')
}
function PopUP() {
window.open("http://domain222.com/2.htm", 'ALpop').focus();
}
</script>
<body>
<a href="#void(0);" onclick="PopUP();" >Click</a>
</body>
File name 2.html on domain222.com
<head>
<title></title>
<meta http-equiv="refresh" content="1;url=http://domain111.com/3.htm?Result=Yes" />
</head>
Filename 2.htm on domain111.com
<script type="text/javascript">
parent.IamParent(); //execute the function from the same domain111.com/1.htm
</script>
Please don't suggest AJAX or web request because it will not work with this case.
Thanks for reading.
Parent windows in other domains are inaccessible due to a security restriction requirement in the JavaScript engines. This applies to all browsers. It is a cross-site scripting attack prevention that cannot be disabled.
