JavaScript - Iframe's Scroll Bar Not Responding To Onmouseup
1) I have a webpage that contains an iframe. The iframe is scrollable.
2) I have the main body of the page responding to onmouseup clicks: <body onmouseup="hideMenus(event)"> And I have the main body of the child page (displayed in the iframe) also responding to onmouseup clicks: <body onmouseup="parent.hideMenus(event)"> So clicks on both pages result in hideMenu() on the parent page being called. Now when the scroll bars on the iframe become visible (due to large amounts of content), I click on the scroll bar, and the hideMenus() function does not respond. I guess the scroll bar is not recognized as part of either the parent page or the iframe's page. I tried adding onmouseup="hideMenus(event)" to the iframe but that didn't help. How can I get mouse clicks on the iframe's scroll bar to result in hideMenu being called? The website can be viewed he http://www.shahspace.com/bow/home.html Similar TutorialsProblem Solved
I have an iframe on my page which currently shows a separate website (one that i do not control). I'm trying to have the iframe automatically scroll to the bottom of the page. I'm pretty sure this is doable through javascript. The website does not have any anchor(s) or anything else that would be useful for what I'm trying to do. I've been stuck on this for over an hour now.. so please help Here is my code <iframe name="frame" id="frame" width="880px" height="600px" src="website" scrolling="no" frameborder="0"></iframe> I have a paragraph of text which is embedded in an IFrame. when i search particular string in that paragraph, if the string is found then the string will be highlighted and the full paragraph is loaded in IFrame. but, if the searched text is at the bottom, then scroll bar in an iframe is not automatically moved to the hidden highlighted text position. any body help me to move the scroll bar automatically to the hidden text position in the IFrame? please run the code, type any text from the paragraph of text and click serach button. see the output.

For example: mypage.html?element3 will cause it to scroll to the element which has an id="element3" when the page loads. Code: <html><head><title></title>
<script type="text/javascript">
function OptionScroll(){
if (location.search.length > 0){
LocnId=unescape(location.search.substring(1))
scrollLocn = document.getElementById(LocnId).offsetTop
document.body.scrollTop = scrollLocn
}

This works fine. Now for the next step, I want to be able to do this from a script embedded in an iframe. In other words, when the page loads, the iframe will load and a script within the iframe executes taking the parameter from the parent page's URL, and then scrolls the parent page to the element with the matching ID. Is it possible to do this? I am building a shopping cart in Volusion. I've come really far and can find my way around HTML and CSS. But the template I am using has a zebra function that it uses on the shopping cart screen. The colors it is using are terrible, and I can't figure out how to change them. By zebra, I mean it picks every other row in a table and assigns a different background color. I am noticing in firebug that the div-ids of the items in the cart have div-ids taht are not listed in any of the CSS files in the theme. I figured out that this type of coding is usually done in JavaScripting. I tried editing that file in every logical way, and I can get no response out of it aside from my browser hanging. I even tried commenting out different sections. Also, the div-ids coming up in firebug aren't found in the .js file either. I'm not sure if you are at all familiar with Volusion, but they provide absolutely no assistance and try very hard to make things as hard as possible so customers will be desperate for their design services. All support will say is, "we are prohibited from providing any coding information. Would you like me to transfer you to sales?" They routinely remove resources that were once helpful. Nice customer service. Anyway, I've been working at this for days and I've come so far I hate being stuck at this point even though I'm just about ready to dump V. Can anyone give me any ideas on what to try? I feel like I've tried everything. I attached the file and here is the URL to the test site: http://v806427.kp5zkqan3xyu.demo22.volusion.com/ Thanks in advance, I'm dying over here. Hi, In the attached code the outcome always defaults to the first test, even if the condition is false. How would I alter the syntax so that both condtions are evalauted? Code: var res = document.calc.num1.value*100/document.calc.num2.value;
function cost1()
{
if (isNaN(res))
{
document.calc.result1.value=0;
}
else
{
document.calc.result1.value=document.calc.num1.value*100/document.calc.num2.value;
}
}
Thanks Iain 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. 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... Does anyone know where I could get a scroller similar to the one used in this recent news div? http://www.383project.com/ thanks! Have a container set to an em height and need the get the scroll or overflow value. Basically need to know if text node inside container has content hidden below the height allowed. How do I get this?
Hi, on my site:http://www.jbiddulph.com/chrisbradshaw/ I need to be able to scroll the whole site horizontally, there may be 20 or so images, ther only way i have figured out how to do it is it guess a max width, like just put width: 5000px; but I cannot determine the whole width with however many images in the page?! I have a javascript below that gets the width of the first image but I need to get width of all images and add 20px padding to the right of each http://www.jbiddulph.com/chrisbradshaw/getwidth.html Can someone please help?! I have looked a Jquery sliders and scrollers and can only find carousels?! Hi, Quick question - I want to find the scrollTop value for some ajax divs but I can't seem to get scrollTop to work. The html looks like this: Code: <div id="media-meta-container" style="width: 302px;">
<p>Subtitles <span id="status" ></span></p>
<div id="scrollbox" >
<div id="content" >
<div id="content_0">Content 0</div>
<div id="content_1">Content 1</div>
<div id="content_2">Content 2</div>
<div id="content_3">Content 3</div>
<div id="content_4">Content 4</div>
</div>
</div>
</div>
Where scrollbox is, you guessed it, a scroll box. I want to find the y position of each of the content divs. I tried this (for exampel for the last element) but it didn't work: Code: var height = $('#content div')[4].attr('scrollTop');
