What I am trying to achieve
I am trying to load a cookie from Website A in the background as a 1 x 1 pixel followed by redirecting users to Website B.
Problem
In the code below, users are redirected to Website B. However, it does not appear that Website A was loading in the background as I could not see the Website A cookie in the browser.
How can I solve this?
Thank you
<html>
<META name="description" HTTP-EQUIV="Refresh" CONTENT="">
<iframe id="MyFrame" style="width: 1px; height: 1px;"></iframe>
</html>
<script>
document.addEventListener("DOMContentLoaded", function(){
const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
var tidParameter = urlParams.get("tid");
var offerParameter = urlParams.get("offer");
console.log (offerParameter);
if (offerParameter == "bb") {
var address = "www.websiteA.com/?tid=";
var combined = address + tidParameter;
var iframeSrcValue = document.getElementById("MyFrame").src;
document.getElementById('MyFrame').setAttribute("src", combined);
document.querySelector('meta[name="description"]').setAttribute("content", "5;url=www.websiteB.com");
}
else if (offerParameter == "bd") {
document.querySelector('meta[name="description"]').setAttribute("content", "5;url=https://www.google.com");
}
else {
document.querySelector('meta[name="description"]').setAttribute("content", "5;url=https://www.hotmail.com");
}
});
</script>
What confuses me
When I try the code in this manner, it works (ie. redirects to Website B and cookie from Website A loads). Unclear to me why the addition of the if, else if causes the problem?

<META HTTP-EQUIV="Refresh" CONTENT="5;url=www.websiteB.com">

const queryString = window.location.search;
const urlParams = new URLSearchParams(queryString);
var mainParameter = urlParams.get('tid');
var address = "www.websiteA.com/?tid=";
var combined = address + mainParameter;
console.log(combined);
var iframeSrcValue = document.getElementById("MyFrame").src;
document.getElementById('MyFrame').setAttribute("src", combined);
});

so i want to print pdf using button and javascript but it will always produce blank pdf/empty pdf. i want something like https://imgur.com/a/PsRqeBR, but i got this instead https://imgur.com/a/J7rzlSq
i try using window.open and then window.print but it still produce blank pdf, i also tried to put url inside window.open instead of declaring it first but that didn't work
HTML
<button type="button" onclick="printme()">click me...</button>
JavaScript
function printme(){
var URL = "https://www.detik.com/";
var W = window.open(URL);
W.window.print();
}
you need to do window.print() instead of w.window.print()
function printme(){
var URL = "https://www.detik.com/";
var W = window.open(URL);
window.print();
}
The source of the following code is Print an external page without opening it
which was mentioned in one of the answers here Printing a web page using just url and without opening new window?
I only modified the link to include your website address:
<!doctype html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>MDN Example</title>
<script type="text/javascript">
function closePrint() {
document.body.removeChild(this.__container__);
}
function setPrint() {
this.contentWindow.__container__ = this;
this.contentWindow.onbeforeunload = closePrint;
this.contentWindow.onafterprint = closePrint;
this.contentWindow.focus(); // Required for IE
this.contentWindow.print();
}
function printPage(sURL) {
var oHiddFrame = document.createElement("iframe");
oHiddFrame.onload = setPrint;
oHiddFrame.style.position = "fixed";
oHiddFrame.style.right = "0";
oHiddFrame.style.bottom = "0";
oHiddFrame.style.width = "0";
oHiddFrame.style.height = "0";
oHiddFrame.style.border = "0";
oHiddFrame.src = sURL;
document.body.appendChild(oHiddFrame);
}
</script>

This issue has shown up in the latest version of Chrome (74.0.3729.108). This is unique to the local filesystem, as I have other ways of loading up neighboring documents in iframes when the app is on a server.
In my app, we have been able to load up documents from the filesystem with JavaScript by writing iframes to the DOM, and then having the document in the iframe write it's innerHTML to sessionStorage. Once the iframe is done loading, we catch that with the onload attribute on the iframe and handle getting the item written to sessionStorage.
I have narrowed this down to some bare-bones code and found that this works only on the first try, and then any tries after the first fail.
Here is a minimal HTML document:
<!DOCTYPE html>
<html>
<head>
<title>Chrome iFrame Tester</title>
<script src="iframe-load.js"></script>
</head>
<body onload="OnLoad()">
<div id="result"></div>
</body>
</html>
Here is the JavaScript:
var urls = ['file://C:/Users/afrench/Documents/Other/Misc%20Code/Chrome%20iFrame/Doc1.html',
'file://C:/Users/afrench/Documents/Other/Misc%20Code/Chrome%20iFrame/Doc2.html'];
HandleLoad = function () {
'use strict';
var data;
try {
data = window.sessionStorage['data'];
delete window.sessionStorage['data'];
} catch (ignore) {
// something went wrong
}
var container = document.getElementById('container');
window.document.body.removeChild(container);
if (data !== null && data !== undefined) {
var resultContainer = document.getElementById('result');
resultContainer.innerHTML += data;
}
if (urls.length > 0) {
OnLoad();
}
}
function OnLoad() {
var url = urls[0];
if (url) {
urls.splice(0, 1);
var container = document.createElement('div');
container.id = 'container';
container.style.visibility = 'hidden';
window.document.body.appendChild(container);
container.innerHTML = '<iframe src="' + url + '" onload="HandleLoad();"></iframe>';
}
}
In the filesystem, we have the HTML written into index.html, and right next to it are two minimal HTML files, Doc1.html and Doc2.html. Their contents are both identical except the identifying sentence in the body's div:
Neighbor document HTML:
<!DOCTYPE html>
<html>
<head>
<title>Chrome iFrame Tester</title>
<script>
function OnLoad() {
try {
window.sessionStorage['data'] = window.document.body.innerHTML;
} catch {
// no luck
}
}
</script>
</head>
<body onload="OnLoad()">
<div>This is Doc 1's content!</div>
</body>
</html>
When this is run, we should see the content HTML of the two neighbor documents written to the result div in index.html.
When I run this minimal example, I can see that the content is successfully written to sessionStorage and then to the DOM for the first document, but the next try fails. What can I do to get it to work consistently, and what is happening here that it fails?
I'm not sure what is causing the weird behavior, so hopefully someone else can provide some insight on what exactly is going on here.
In the meantime, here is an alternative solution using window.postMessage:
index.html
<!DOCTYPE html>
<html>
<head>
<title>Chrome iFrame Tester</title>
<script src="iframe-load.js"></script>
</head>
<body onload="OnLoad()">
<div id="result"></div>
</body>
</html>
iframe-load.js
var urls = ['file://C:/Users/afrench/Documents/Other/Misc%20Code/Chrome%20iFrame/Doc1.html',
'file://C:/Users/afrench/Documents/Other/Misc%20Code/Chrome%20iFrame/Doc2.html'];
window.addEventListener('message', event => {
'use strict';
var data = event.data;
var container = document.getElementById('container');
window.document.body.removeChild(container);
if (data) {
var resultContainer = document.getElementById('result');
resultContainer.innerHTML += data;
}
if (urls.length > 0) {
OnLoad();
}
})
function OnLoad() {
var url = urls.shift();
if (url) {
var container = document.createElement('div');
container.id = 'container';
container.style.visibility = 'hidden';
window.document.body.appendChild(container);
container.innerHTML = '<iframe src="' + url + '"></iframe>';
}
}
Doc1.html
<!DOCTYPE html>
<html>
<head>
<title>Chrome iFrame Tester</title>
<script>
function OnLoad() {
window.parent.postMessage(window.document.body.innerHTML, '*');
}
</script>
</head>
<body onload="OnLoad()">
<div>This is Doc 1's content!</div>
</body>
</html>
So this code selects random image whenever a person loads my website, how can I change the code so that images are selected sequentially from first to last everytime a person loads the website and then again resets to first image when the counter reaches the end?
P.s- The code works fine on hosting server, here it gives an error i don't know why.
window.onload = choosePic;
var myPix = new Array("https://i.imgur.com/LHtVLbh.jpg", "https://i.imgur.com/2YHazkp.png", "https://i.imgur.com/Uscmgqx.jpg");
function choosePic() {
var randomNum = Math.floor(Math.random() * myPix.length);
document.getElementById("myPicture").src = myPix[randomNum];
}
<!DOCTYPE html>
<html>
<head>
<title>Random Image</title>
<script src="thumb.js"></script>
</head>
<body>
<img src="images/spacer.gif" id="myPicture" alt="some image">
</body>
</html>
You can use localstorage to achieve this. When the user enters the website, you can do something like:
var pictureIndex = localstorage.getItem("pictureIndex");
But since it may be the user's first visit, it would be better to have:
var pictureIndex = localstorage.getItem("pictureIndex") || 0;
Then, you just increment the pictureIndex and perform a modulo operation (for the case when this is the last image)
pictureIndex = (pictureIndex + 1) % myPix.length;
To save this index, you can use
localStorage.setItem('pictureIndex', pictureIndex);
Next time when the user refreshes the page (or comes back), he will get the next picture in your array.
The final code should look like this:
window.onload = choosePic;
var myPix = new Array("https://i.imgur.com/LHtVLbh.jpg", "https://i.imgur.com/2YHazkp.png", "https://i.imgur.com/Uscmgqx.jpg");
function choosePic() {
var pictureIndex = window.localStorage.getItem("pictureIndex") || 0;
pictureIndex = (pictureIndex + 1) % myPix.length;
window.localStorage.setItem("pictureIndex", pictureIndex);
document.getElementById("imgid").innerHTML = pictureIndex;
document.getElementById("myPicture").src = myPix[pictureIndex];
}
<!DOCTYPE html>
<html>
<head>
<title>Random Image</title>
<script src="thumb.js"></script>
</head>
<body>
Press "Run" multiple times to cycle through the images.
Currently showing: <span id="imgid"></span>
<img src="images/spacer.gif" id="myPicture" alt="some image">
</body>
</html>
Note that the above code might not work here (but you can test it locally) due to some security restrictions from jsfiddle. A working version can be accessed >here<
function choosePic() {
var local_item = 0;
if(localStorage.getItem('pic_key')){
local_item = parseInt(intvlocalStorage.getItem('pic_key'));
}
if(local_item >= myPix.length){
local_item = 0;
}
localStorage.setItem('pic_key', local_item + 1);
document.getElementById("myPicture").src = myPix[local_item];
}
You can use LocalStorage to achieve this. When the user enters the website, you can store the key and increment it.
Use local storage to save the data you need [e.g. visited = 3(3rd time the same person visited your website)]
Your js code can be implemented like this:
window.onload = choosePic;
var myPix = new Array("https://i.imgur.com/LHtVLbh.jpg", "https://i.imgur.com/2YHazkp.png", "https://i.imgur.com/Uscmgqx.jpg");
function choosePic() {
if (localStorage.getItem('visited') == null)
{
document.getElementById("myPicture").src = myPix[0];
localStorage.setItem('visited', 1);
}
else if (localStorage.getItem('visited') >= myPix.length)
{
localStorage.setItem('visited', 0);
document.getElementById("myPicture").src = myPix[localStorage.getItem('visited')];
}
else
{
document.getElementById("myPicture").src = myPix[localStorage.getItem('visited')];
localStorage.setItem('visited', localStorage.getItem('visited') + 1);
}
}
Okay, I am developing a web application using MVC 4 and I want to display Ads from Chitika. I don't want these ad's to be blocked by the client side. I was wondering if it is possible to have the javascript for the chitika ads on a static html page.
<div class="ads">
<script type="text/javascript">
ch_client = "";
ch_width = 728;
ch_height = 90;
ch_type = "";
ch_sid = "";
ch_color_site_link = "0000CC";
ch_color_title = "0000CC";
ch_color_border = "F4F1E6";
ch_color_text = "000000";
ch_color_bg = "F4F1E6";
</script>
<script src="http://scripts.chitika.net/eminimalls/amm.js" type="text/javascript">
</script>
</div>
And then call the page like so:
var Request = (HttpWebRequest)WebRequest.Create("/adsstatic.html");
var adResult = (HttpWebResponse)Request.GetResponse();
Stream receiveStream = adResult.GetResponseStream();
StreamReader readStream = new StreamReader(receiveStream, Encoding.UTF8);
return readStream.ToString();
and then display the returned html on the view? Is this totally stupid?
Thanks
I have a swf file created by EasyPano tourweaver software. the outpout is a swf file with some .bin files to config the swf and other files such as .jpg, .js and so on.
The software create a html file to add the swf but i have to load the swf using flash and AS3. the HTML and JavaScript that the software create is :

Please Help me!

The answer is URLVariables passed to the URLRequest feed into load method of Loader:)
example:
var loader:Loader = new Loader();
var flashvars:URLVariables = new URLVariables()
flashvars["lwImg"] = "resources/talarmahan_1_firstpage.jpg";
flashvars["lwBgColor"] = "255,255,255,255";
flashvars["lwBarBgColor"] = "255,232,232,232";
flashvars["lwBarColor"] = "255,153,102,153";
flashvars["lwBarBounds"] = "-156,172,304,8";
flashvars["lwlocation"] = "4";
flashvars["lwShowLoadingPercent"] = "false";
flashvars["lwTextColor"] = "255,0,0,204";
flashvars["iniFile"] = "config_TalarMahan.bin";
flashvars["progressType"] = "0";
flashvars["swfFile"] = "";
flashvars["href"] = this.loaderInfo.url;
var request:URLRequest = new URLRequest("twviewer.swf");
request.data = flashvars;
loader.load(request);
addChild(loader);
also with following helper method you can get main SWF parameters (from it's html wrapper) and pass it to the loaded SWF:
public function getFlashVars(li:LoaderInfo):URLVariables
{
var vars:URLVariables = new URLVariables();
try
{
var params:Object = li.parameters;
var key:String;
for(key in params)
{
vars[key] = String(params[key]);
}
}
catch(e:Error)
{
}
return vars;
}
then
var loader:Loader = new Loader();
var request:URLRequest = new URLRequest("twviewer.swf");
request.data = getFlashVars(this.loaderInfo);
loader.load(request);
addChild(loader);
For SecurityError: Error#2000 and here - there are many reasons behind this error
