JavaScript - Locate Some Text Within An Iframe
Hi,
I'm trying to locate some text within an iframe highlighting the string found. I was wondering if someone knows a good way to do Stickers Similar TutorialsHey there, I'm having difficulties writing a script that should do the following: 1. "visit"/connect to a website 2. search after rss feeds on the site 3. grab the rss link and make it useable for other scripts (array...) If anybody could guide me on how to do that I would be grateful.. thanks! This has been driving me nuts, let me start off by saying this is what I'm currently working with... I've included a js file in the header of the site which utilizes a function in a php file. Just the standard Code: <script language="javascript" src="http://yourwebsitehere.com/includes/js.js"></script> In the .js file I'm setting the location to a php file as a variable... Code: var url="/file-here.php"; url=document.location.host+url; Obviously the document.location.host isn't working for me but here's what's going on... At first I just had, Code: var ="http://www.domain.com/file-here.php"; in the js file. So if the user is on www.domain.com/some-directory/another/ the script will work, however if the user is on domain.com/some-directory/another the script won't work, because I've included www. in the variable within the js file. However, if I set it to Code: var ="http://domain.com/file-here.php"; , it will work on domain.com/some-directory/ but not on www.domain.com/some-directory. So basically I need to return the host url somehow, depending on if the user is on the page with www. or without www. so it will always work. With php, I could just use Code: $server['HTTP_HOST']/file-here.php and it will always return www.domain.com or domain.com depending on the URL the user is on, but obviously php won't work in a js file so I'm looking for the correct string/command to get this. Anyone have any idea how to return just the www.domain.com or domain.com portion of the current URL with javascript? So no matter where they are on the site, with or without www. the script can still function by having the correct URL to the PHP file at all times? Hello I need to get text from an iframe. I tried this example (I've found it on this board): Code: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<title>Example</title>
<style type="text/css">
</style>
<script type="text/javascript">
// <![CDATA[
window.onload = function()
{
// treat iframe_window as if it were your iframes window (which it is)
var iframe_window = window.frames["my_iframe"];
// compare the following line to: window.document.getElementsByTagName("body")[0].innerHTML;
var iframe_body_html = iframe_window.document.getElementsByTagName("body")[0].innerHTML;
alert(iframe_body_html);
}
// ]]>
</script>
</head>
<body>
<iframe name="my_iframe" id="my_iframe" src="example.html"></iframe>
</body>
</html>
but it works only with window.onload event. I need to get this text dynamically (e.g. on click). could you give me some example? Regards. I use the following code to create a hidden iFrame on a page, dynamically Code: var i = document.createElement('iframe');
i.style.display = 'none';
i.onload = function() { i.parentNode.removeChild(i);};
i.src = 'http://www.mysite.com';
document.body.appendChild(i);
i.id='frame1';
Now, document.getElementById('frame1').contentDocument.getElementById('text01').value Should have given me the value in 'text01', but it doesn't. It doesn't work even inside the iFrame's onload event. ('text01' is a textbox which is on the page inside the iFrame - its name and id are both 'text01') Is there any other method to get the text in a textbox within an iFrame? Please help me to correct the code. Thanks in advance. Hi world I have this code in my page PHP Code: <iframe name="ff1" src="http://playerplus.co.nu/ipp.php" ></iframe> how i copy the result in this iframe to text or to some variable but from iframe not direct from the URL "http://playerplus.co.nu/ipp.php" I have referenced the following thread for ideas on the issue I want solved, but only took it as far as I can. Any help would be great. http://codingforums.com/showthread.php?t=202459 I would like to utilize this script where I could pass the string of words to another page. Meaning, search for the text, actually a word, then take the two words following the searched text and have them passed to the next page...I have tried to "alert" the words, but have no success. I have tried to modify the code using the following, but the result just posts a "-1" in my alert popup. As you can see I modified the code from the original thread in the third block of "for" code. also, I added an "alert" tag. One more thing, I added a function call for the form button. Hope you can help out. The code is below: Code: <script type="text/javascript">
var count = 0;
var itemList = new Array();
var oldText = "";

Join Chief Economist Mark Zandi and Director of Housing Economics Celia Chen for an introduction to Housing in Crisis: When Will Metro Markets Recover?, a new study that offers a comprehensive look at the near-term prospects for a recovery in housing markets in a recessionary environment. In addition, Dr. Zandi will critique the effectiveness of policy thus far in the housing crisis and discuss additional measures the Obama administration will enact that are assumed in the Moody's Economy.com house price forecast. Key findings:- In about 10% of metro areas, price declines will exceed 30%.
Economic experiments in virtual worlds (or, more generally, virtual economies) have been proposed a number of times and also conducted to some extent. A recent addition to the conducting category is Reciprocity and status in a virtual field experiment by Andreas Nicklisch and Tobias Salz. In their study, the authors conducted a field study in World of Warcraft, seeking to investigate the role of reciprocity, and the effect of status on reciprocity, in employment relations. Reciprocity here means the observed tendency to react kindly to kind actions, even though such reactions are not enforced. Unlike previous economic experiments conducted in virtual worlds, the authors did not create an artificial setup for the experiment. Below, I summarize and briefly discuss the study and its findings.

Death = $Mill Hi all, I'm trying to get the cursor position to move to the end of the text within an editable iframe or div. I've been pointed to something called TextRange and have been reading up on it for days yet couldnt make sense of much (i'm still very new). what i'm trying to do is on a button click, the cursor will move to the end of the text in the iframe. any help or pointers would be greatly appreciated. thanks. I am looking to scan a page, find all the url's on the page. Once I have them, I want to append the front of the url (hardcoded and never changes) with hardcoded code. Like a Find and Replace. for example: locate the front of all the urls which is - wincfprod032 and replace with wincfprod032.jewels 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 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 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. 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... |
