JavaScript - Iframe Interaction
Ok so I'm playing around with writing scripts reading through JavaScript: The Definitive Guide and I'm on the Section "Relationships Between Frames".
All i'm trying to do is change the background color of the <div id=iframewrap> element, which is inside the iframe, by clicking on the paragraph that says "Click Me", which is inside the iframe's parent window. I have everything I tried below along with the error message recieved by firebug. I Cant figure it out. HTML Code: <p>Click below to change the style of the iframe</p> <p style="color:blue" onClick="chngFrameStyle()">Click Me</p> <iframe id="fone" name="fone" src="OreillyCh14v2Iframe.html" width="50%" height="400px" ></iframe> The iframe Code: <div id="iframewrap" > <h1>Iframe Window</h1> <div id="iframeparagraph"><p>Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa <strong>strong</strong>. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus.

Hey all, Whenever firebug detects a js error on a page, it prevents you from interacting with the page, so you can't scroll, you can't click, you can't do anything except close the window. Anyway around this? Thanks. Hello, I am looking for some strong resources about the topics above. I am trying to create a map for my website that visualizes Americas opinions on who will win the 2012 election... Obama vs the Republicans. I have a data set that will be the base, but I would like to update the map as users take the accompanying poll and as the data set changes. Any ideas or information would be awesome! Thanks 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? Hi 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 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. help me! im have 2 file .js file 1.js code: document.write("<script src=2.js></script>") document.write(f) file 2.js code: var f="hello" im want run 1.js get variable of file 2.js by 3.html but don't run! code 3.html <script src=1.js></script> 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 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? Hello.... I've 2 iframes. And i want to change the css class of second iframe anchor tag from the first. Code: <div id="top-navigation" title="top-navi">
<ul><li id="homePageLink" class="first">
<a id="homePageTab" class="navigation-font" href="</a>
</li>
</ul>
</div>
In the above code how can i change the class="navigation-font" from the first iframe? Please help.... Hi I have a page with 3 iFrames, showing different content. iFrame1: Here is a navigation php page. Click on a menu item and it loads a php page in iFrame2 iFrame2: Here is a list of items from a database. iFrame3: I load 3 different php pages here. (A) is the main showing page. (B) and (C) is a record manipulation page, that does some editing in the database and then redirects to (A). When the (A) php page loads, it should reload iFrame2 I have tried to put something like: <body onLoad=parent.location.reload()> and put it on the (A) php page. This will reload the entire page, which works. However, it results in a loop of reloads, as the (A) iFrame file will load with the entire page reload... So, I was looking for the right code to put, like onLoad=iFrame2.location.reload() However, I can't seem to find the correct code, so I hope any of you can help me... Above is the image of my situation, what I need is for the captcha's to be loaded perfectly and displayed to the user as shown in the image with the green box around it, I currently have a script to set focus to the text field however it is kind of messy for some reason and ends up leaving it looking like the frame in the red box in the image. Here is what I have been using: Code: if (( document.URL.indexOf("cast_skills") != -1 ) || ( document.URL.indexOf("security_prompt") != -1 ) || ( document.URL.indexOf("joinraid") != -1 )){
if ( document.forms.length > 0 ) {
document.forms[0].elements[1].focus();
}
}
This works fine since on each of the pages it is required there is only 1 form. However when loading smaller frames it causes some problem. The next question I have to ask is, is it possible to have a script that when the enter key is pressed inside frame 1, automatically move the focus on to the text field in frame 2? Noting that the page inside the frames is not my own and I cannot do anything with it. Any help would be appreciated with this matter, Many thanks. Hello Experts I need your advice. I dont know if this is the write place to post my query. But I have an assignment due today. I have got everything working except an iframe that is driving me nuts. the question on the assignment asks to insert a command to write the HTML code <iframe src='weekday.htm'></iframe> to the webpage where weekday is the text string returned by the weekDay() function. The iframe should display the daily schedules that are stored in the sunday.htm through saturday.htm file. The weekDay() function is located in an external .js file that I have already linked to my webpage. Another thing is there is no weekday.htm file instead there are files sunday.htm through saturday.htm that have the daily schedules to de displayed in the iframe. I know that I should some link the weekday.htm file to the weekDay() function. This is what I have done so far: <h2 id="title">Today at the Union</h2> <p> <script type="text/javascript"> /* Dispaly the daily schedule in an inline frame. Display schedules are stored in the files sunday.htm through saturday.htm */ <iframe src='weekday.htm'> var weekday = weekDay(); document.write(weekday); </iframe> </script> </p> Please advice as to how to get this thing working. I am not an expert( I am still learning.) I tried my best (spent several hours breaking my head on this). So any help is much appreciated. Thank you for your time Hi Am new to javascript.
