JavaScript - Popup A Message Out Of A Hidden Iframe
Hey guys i am creating a Greasemonkey script that adds an ajax chat to a website. Greasemonkey is an addon for firefox that lets you modify the html code of websites before they are showed to the user.
I am in the process of creating a wizz feature that will allow you to send a message to a member and where ever he is on the web his gona receive it. The way it works right now is there's a hidden iframe in every page load and when the player has a message it popups a small window It's working great but the popup is always instantly blocked because firefox has a popup bloker integrated and because it can popup on random websites they don't allow it and there for never gets the message ... Everything else i tryed was blocked by the fact that it opens in the iframe that is invisible. I even tryed doing it the old fashon way with an alert() but same thing you don't see it because it's in the hidden frame. And i tryed adding top.alert() but i get a javascript the "Access Denied" message. The "Access Denied" error in any browser usually means that a script in one window or frame is trying to access another window or frame whose document's domain is different from the document containing the script. I know DHTML AJAX popup would be the only way to give the user the message with out being blocked ... but how can i make it popup out of the iframe into the main frame with out being blocked in anyway ... I am out of ideas ... Similar TutorialsHi all, I hope you can help I have some code which: 1) Opens a URL (e.g. google.com) in a hidden iframe, then 2) Redirects the visitor to a different URL (e.g. yahoo.com) after it has loaded... This works exactly as I need. What I'd like to do is the following: 1) Open a URL (e.g. google.com) in a hidden iframe, then 2) Redirect the visitor to a different URL (e.g. yahoo.com) in a full-screen iframe 3) The address bar of the full-screen iframe should be my domain (obviously!) Here's what I have so far... Hidden iframe -> New URL Code: Code: <html>
<body>
<script type="text/javascript">
var page_body = document.getElementsByTagName('body');
var myframe = document.createElement('iframe');
var id = Math.random();
myframe.setAttribute('id', 'myFrame'+id);
myframe.src = 'http://google.com'; //First open Google in hidden iframe
myframe.setAttribute('frameborder', '0')
myframe.setAttribute('width', '0');
myframe.setAttribute('height', '0');
if (myframe.attachEvent)
{
myframe.attachEvent('onload', function()
{
top.location = 'http://yahoo.com'; //Once loaded redirect to Yahoo -- but the address bar shows yahoo.com -- I want the address bar to display mydomain.com/page.html
});
}
else if (myframe.addEventListener)
{
myframe.addEventListener('load', function()
{
top.location = ('http://yahoo.com');
}, false);
}
page_body[0].appendChild(myframe);
</script>
</body>
</html>
I have an example of some code which displays the full screen iframe, but my problem is... ...I can't figure out how to redirect to this after the hidden iframe has loaded Here's an example of how I want the redirect to display -- after the initial hidden iframe has loaded: Code: <html>
<head>
<script type="text/javascript">
function sendParams() {
document.body.style.overflow = "hidden";
}
</script>
</head>
<body>
<!--Open Yahoo.com in a full screen iframe, and disable extra scrollbar -->
<iframe height="100%" width="100%" frameBorder="no" onload="sendParams()" src="http://yahoo.com"></iframe>
</body>
</html>
I've been beating my head against the wall today trying to figure this out, and I'm fresh out of ideas. If you can help, you'll have some serious gratitude and good karma thrown your way! Best wishes, and thanks in advance, Paul Hi all, I hope someone can advise whether such a script exists for what am wanting to do. From time to time, I need to send password information or login details and password information to some users. At the moment, am doing it via email with a subject named FYI and the body of the email basically just contain the login and the password or in some case, just the password. What am wanting to know is whether I can put these information into a HTML file which contains an obfuscated Javascript with a button that a user will click that will prompt for his login information and then will display the password. In its simplest form, I guess I am looking for a Javascript that will obfuscate a HTML file that contains the password. Anyway, hopefully someone understand what am looking for. I found some website that offers such service as obfuscating a HTML file but am hoping it can be done via a Javascript so it is at least "portable" and I do not have to be online. Any advice will be much appreciated. Thanks in advance. Hello! I have a script that loads a popup window on any page of a website, in order to temporarily cover the page's content. This popup window is supposed to load on top of page's content, acting as a sort of page blocker. So the visitor can't see what's on the page until he clicks the popup. The problem i'm having right now is when i put this script on a page that has iframe content. The iframe loads on top of this popup and not underneath as it's supposed to be. Do you guys have any advise on what should i do to make this work properly when using iframes on a page? Here is the script: Code: var blocker_originalHtmlOverflow;

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. :-) Is there a way to resize an iframe dynamically so that you never get the scroll bar and essentially hide that there is an iframe? Better integration really. Basically I want to iframe a forum into my site so that the design down the sides and top which my friend does using iweb are not messed with. We have a central area which can be longer or shorter depending on the forum. Hi there everybody, I've got this problem which I can't solve myself... I've got a website which has 3 colums and is hosted on domain1.com. in the right column I've got an Iframe which loads content from domain2.com . this content are some textboxes and a datepicker tool. if I press the 'search'-button in this Iframe I would like to refresh the mainpage (from domain1.com) so that another Iframe appears in the middle column. in this column i would like to load a new form from domain2.com which contains the values that I've put in in the form from the right Iframe. Unfortunally I can't get this to work... Will somebody please help me? I have used iframes for my site and found various javascripts so when a person clicks on say the audio page he http://www.krillmeed.com/index.html it takes them to the audio page but will load it into the index.html page. The problem is, especially with search engines, to point to that page, this is what the URL looks like to send someone to that page: http://www.krillmeed.com/?frame=0&sr...m%2Faudio.html which is not very clean at all, this is the javascript that i found that at least works: Child iframe script: Code: <script type="text/javascript">
(function(){
var qstr = '?frame=0&src=' + encodeURIComponent(location.href),
lre = new RegExp('^' + location.protocol + '//' + location.hostname + '(()|(/)|(/index.html)|(/index.php))(()|(\\' + qstr + '))$');
if (!lre.test(parent.location.href)){
top.location.href = '/' + qstr;
}
})();
</script>
Parent iframe Script: Code: <script type="text/javascript">
(function(){
function getQval(n) {
if(typeof n !== 'string'){
return null;
}
var r = new RegExp('[?&;]' + n + '=([^&;#]*)'), m = location.search;
return (m = r.exec(m))? unescape(m[1]) : null;
}
var f = getQval('frame'), s = getQval('src');
if(f && frames[f] && s && s.indexOf(location.protocol + '//' + location.hostname + '/') === 0){
frames[f].location.href = s;
}
})();
</script>
Is there a "cleaner" way of doing this? This was an old code, i have yet to find a more modern one. Thank you in advance. Hi, Not sure if I worded that question right. I have a web page which will display another web page in an iframe. But the content inside the iframe may change while the user interacts with it so I need to be able to resize the iframe height from code on the page inside the iframe. Any tips on how I can do that? I am using php and javascript. Thanks. hello, This seems very basic, but I am running into a complication. What I would like to do is check if a certain div is displayed or hidden (really doesnt matter which) then set a map zoom level based upon that. here is my current function. function closeDirections(){ gdir.clear(); if(document.getElementById("river").style.display="none"){ map.setZoom(16); hideID('river'); showID('main'); } if(document.getElementById("main").style.display="none"){ map.setZoom(12); hideID('main'); showID('river'); } } Also here is a link to my map, just in case. map I have tried several variations, but from what I can tell with every instance, it only examines the first and never considers the second "if". I thought to rememdy this issue by using if/else...same issue. The only thing I could think is a nested if statements, but I am not sure what to use as a parent if. I have searched for a while, but cannot seem to find something like an .is_hidden(). Something that I could see if its true/false. Any help would be very much appreciated. Hello. The link below is the result of a product search on a website. It displays 2 results. However, the actual results (picture & information) that are displayed on the web page are not present in the "Page Source". For example, if you search the page source for the string '860723' (which is one of the product numbers visible on the web page) it is not there. What is going on here? It looks to me like dummy images & information in the HTML are first loaded by the browser, and then that dummy info gets replaced by the real information via a javascript function. Is that what's going on? http://www.lightsamerica.com/metro/s...mber:SL9469-8; I'm trying to retrieve that information by downloading the source in my PHP program. The problem is that the information I want isn't present in the source. It stands to reason that the information is somehow being sent to the browser because I can see it... any ideas? Thanks for your time, -Scott Hey guys! How are ya? Gettin' right to the point, I need a help! I already created a javascript code to hide my div when click on close "[x]". What I need to do is get it movin' around the website here's the code: it's between <head></head> Code: <script language=javascript type='text/javascript'>
function hidediv() {
if (document.getElementById) { // DOM3 = IE5, NS6
document.getElementById('hideShow').style.visibility = 'hidden';
}
else {
if (document.layers) { // Netscape 4
document.hideShow.visibility = 'hidden';
}
else { // IE 4
document.all.hideShow.style.visibility = 'hidden';
}
}
}
function showdiv() {
if (document.getElementById) { // DOM3 = IE5, NS6
document.getElementById('hideShow').style.visibility = 'visible';
}
else {
if (document.layers) { // Netscape 4
document.hideShow.visibility = 'visible';
}
else { // IE 4
document.all.hideShow.style.visibility = 'visible';
}
}
}
</script>
and it's between <body></body> Code: <div id="hideShow"> <img src="../imagens/tela01CQ_07.jpg" alt="teste"/><a href="javascript:hidediv()">[x]</a></div> and it's in CSS Code: #hideShow {
position:absolute;
margin: 300px 110px;
}
thx! Hi all I believe this to be a JS quesiton, but perhaps there is something here of CSS too? I have an "ecard" which is: - a <div id="outer_ecard"> wrapping an <iframe>... - is hidden by default (via a JS function that fires onload of the parent doc), .. - that gets its display and visibility turned on when the user clicks a link in the parent doc, ... - and then gets its display and visibility turned off again via a call to that same JS function in the parent doc that hid it in the first place by default. here is just the relevant snip of the hiding JS function - Code: elementToSet.style.display = "none"; elementToSet.style.visibility = "hidden"; everything works fine, *BUT* this issue: after the <div> disappears (the 2nd time, when the above snip is triggered in the iframe's parent via an onload event in the iframe doc)... then hyperlinks (in the parent file) that are geographically positioned underneath the <div id="outer_ecard"> do not work (i.e. they still think the ecard div is sitting on top of them (z-index:1). Can anyone advise me here? I need the links underneath the ecard to behave as though that div was never there. Thanks! -Govinda Need to append a hidden value to a floating div that is made via javascript.

After searching the web most of the day, nothing has resolved this issue: Code: <!-- ALERT IS NEVER HIT -->
<html>
<input type="hidden" id="info" name="info" value="testInformation"/>
<script type="text/javascript">
var me = document.getElementById('info').value;
alert(me);
</script>
</html>
Code: <!-- ALERT SAYS "null" -->
<html>
<input type="hidden" id="info" name="info" value="testInformation"/>
<script type="text/javascript">
var me = document.getElementById('info');
alert(me);
</script>
</html>
Code: <!-- WORKS GREAT, BUT I NEED THE INPUT FIELD HIDDEN -->
<html>
<input type="text" id="info" name="info" value="testInformation"/>
<script type="text/javascript">
var me = document.getElementById('info').value;
alert(me);
</script>
</html>
Any idea how I can keep the input value "hidden" and have javascript still see the value? And yes, I've even tried using the "defer" method. Hello to all and thanks in advance for my help. I know this has been posted in different places on the web but I have found no solid solution. Here is my problem: I have an iframe the loads up a page on a remote server (out of my hands) and when I send certain information to it, the page redirects my entire site to their 404 page. I need to prevent this from happening so I engaged in much research and found this... temporary fix: Code: <script>
// No redirection!
var prevent_bust = 0
window.onbeforeunload = function() { prevent_bust++ }
setInterval(function() {
if (prevent_bust > 0) {
prevent_bust -= 2
window.top.location = 'http://www.mysite.com/my404.html'
}
}, 1)
</script>
What this code does, is that every time the unload of a page happens, it will redirect me to my404.html and this does solve the problem of the iframe trying to redirect my entire site but anytime a user tried to go to a new website by typing it in the address bar, they are redirected to my404.html. Is there another solution for me so that the page within the iframe cannot redirect the parent page? I have an iframe that is a specific height and width. I want to detect whenever the the iframe is no longer exactly the height i set it to. If a user has CSS turned off for example the iframe will be in default height and width. I want to detect that. This is how you'd normally do it but this only returns the original size (try with 'no style' in Firefox): Code: function getSize()
{
alert('height is now '+document.getElementById("Iframemain").height)
alert('height is now '+document.getElementById("Iframemain").width)
}
Is it possible? hello, i have a form in my header that is hidden and i have it show when you click a link, the problem is, when the form appears, it pushes everything down below it, any ideas on how to get around this?
I have a script that brings up an overlay box onclick that needs to be on top of everything else on page, however I can't get it to show on top of the navigation tabs. I tried calling the overlay script at the very beginning of the head section as well as tried to call it at the end but it doesn't seem to matter. Is there something I can add to the script to force it on top of every other object on the page? I have a simple script connect to a radio button. Based on which option, the matching div appears with a text box - and one with a radio button. If they change their mind and click another radio button, it'll switch to the new div, but keep the content in the old. How do I clear that out? I looked for a snippet, but they're all for clearing default text in a field when you click it. I want something a little different. Here's what I'm using: Code: <script>
$(document).ready(function() {
$("div.desc").hide();
$("input[name$='hear']").click(function() {
var test = $(this).val();
$("div.desc").hide();
$("#" + test).show();
});
});
</script>
<input type="radio" name="hear" value="dcranch"> DC Ranch Community <br />
<input type="radio" name="hear" value="friend"> From a friend <br />
<div style="display: none;" id="dcranch" class="desc"> <input type="checkbox" value="Yes" name="resident" /> If so, are you a DC Ranch resident? )</div><br />
<div style="display: none;" id="friend" class="desc"> Name? <input type="text" name="how1" /></div><br />
Hey Guys, I have the following hidden field within a form: Code: <input type="hidden" name="test12" value="test12" /> I also have the following function which does something if that field exists: Code: if(document.formName.test12.value == "thisdata")
{
//do something
}
The problem I'm having is that if the hidden field doesn't display (which based on conditional logic, sometimes happens), a JS error is thrown on the page. What is the best way to carry out this check effectively without throwing an error if the field does not exist? Thanks in advance. |
