JavaScript - Change Source Of Iframe After Page Has Loaded
Im very new to java scripting so any help would be truly appreciated. I have a single web page that loads several iframes. One of the iframe pages has to be logged in first. I have that taken care of but once the page is loaded I need to change the source to a link with in the page. My guess is I need something to execute the code like a onload or something. This is what Ive been trying to get to work but like I said a newb!
The iframe in question is named "cad" the initial source once loaded is 'https://urlname.com/mainmenu.asp' the source I need to change to is 'https://urlname.com/UnitStatusF.asp?agency_id=28' [CODE] function ChangesSrc() { var iframeid = document.getElementById(cad); var unitstatus = 'https://urlname.com/UnitStatusF.asp?agency_id=28' if (iframeid.src = 'https://urlname.com/mainmenu.asp') iframeid.src = unitstaus; return false; } [[CODE] Similar TutorialsThe project I am working on involves a flash piece that communicates with a iframe. Currently the flash piece just calls on javascript functions. I want the buttons in the flash piece to be able to change the src of the iframe. PHP Code: <script type="text/javascript"> document.getElementById('video').setAttribute('src',address2); function closeVideo() { document.getElementById('video').style.height='0px'; return false; document.getElementById('video').setAttribute('src', address2); } function openVideo() { document.getElementById('video').style.height='391px'; return false; document.getElementById('video').setAttribute('src', address); } </script> So the way the code works now is when the page loads it sets the iframe with the id of 'video' to the variable address2 which it pulls from an XML file. In the flash piece when a button is hit, it calls openVideo() which "opens" the iframe and I want it to change the contents to address. This does not work though. It opens the frame but will not change the src. I've tried a bunch of different things now such as make the flash target the iframe using navigateToURL(request1, 'video'); but in Firefox and IE is opens it stills as if I had _blank in there. It does strangely work in Safari. Any ideas how to get this to work? I'm new to javascript so it could be something basic I'm overlooking Hi all, I am facing problem in preventing my web page being loaded into an iFrame. I search in internet and found this solution : if (self == top) document.documentElement.style.display = 'block'; else top.location = self.location; The above java script code is simple redirecting me to the home page of my web site. But I donot want that kind of solution. When anybody tried to access my web page through iFrame, it should show an error message like "The content of the web site cannot be loaded into an IFrame". This message should be displayed inside the iFrame. For example, if we tried to access "google.com" site in an iframe, the website should not allow the iframe object to load into it, insted it will display an error message along with a provision to open webiste with an external link with it. Any help? thanks, -Sanath I doubt this is possible, but I have no idea what actually happens when a page loads, so I thought I would give it a shot... if a js file that is loaded externally has parameters, is it possible to turn those parameters into variables, giving the user the option to select the variable's value after the page has loaded? maybe a concrete example would be better... in google maps, the api is loaded like this: Code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> but if you wanted to specify that you want the api to function in Spanish, you load it like this: Code: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&language=es"></script> and that language=es is the one that I want to change. But I can't seem to make it into a variable on page load, like this: Code: <script type="text/javascript"> var lang="es"; </script> <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false&language=lang"></script> much less make it changeable once the page has loaded. I have a feeling that this is a really dumb question, but can it be done without reloading the entire page? In my page, I have a main iframe where I want all the content of my links to be loaded. I want the iframe's height to resize according to the content. All the linked pages are in the same domain. I have tried some scripts I found, but nothing has the result I want. The HTML code is: Code: <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>index</title> <link href="styles.css" rel="stylesheet" type="text/css" /> </head> <body> <div id="container"> <div id="header"></div> <div id="nav"> <a href="home.html" target="frame">Home</a> <a href="the_band.html" target="frame">The Band</a> <a href="News.html" target="frame">News</a> <a href="gallery.html" target="frame">Gallery</a> <a href="contact.html" target="frame">Contact</a> </div> <iframe id="frame"></iframe> <div id="footer"></div> </div> </body> </html> The CSS code is: Code: div#container {
height: 100%;
width: 100%;
}
div#header {
top: 0px;
width: 100%;
height: 80px;

I don't know how to make scripts on my own, so I would appreciate any help. Thank you! I'm trying to write a progressively enhanced web application. I have an index page and a form with some select boxes and some radio buttons on a different php page. Before enhancement occurs, the form is accessible via regular links and everything works as expected. No issues. In the enhanced version of the application, the form is AJAXed into the index page. When this occurs, the select boxes in the form work perfectly. The radio buttons are initially unchecked and I can check one option as usual. However, once one is checked, clicking the other radio options does nothing. I am unable to check a different option. Anybody got a clue what the problem is? Using Chrome by the way. Firefox is the same as Chrome. In IE I can't even check a radio button the first time. Here's the code that's ajaxed in: Code: <label>First Time Buyer Status <!--These values can't be 1/0 because 0 stands for not set--> <input type="radio" name="FTB" id="FTBYes" value="1" <?php $M->checkFTBValue(1); ?> title=""/>First Time Buyer <input type="radio" name="FTB" id="FTBNo" value="2" <?php $M->checkFTBValue(2); ?> title=""/>Not First Time Buyer </label> The PHP script you see there checks if the value on the server matches the value of the radio button and echo's checked="checked" if true. I thought this could be causing the problem initially but the exact same code is used in the non-enhanced version and it works fine. I tried commenting it out anyway but it makes no difference. The only thing I can think of is that some javascript is preventing me from selecting a different radio option. That would explain why it works ok in the non-enhanced version because there is no JS there. I can't find anything that I've written that might cause this effect I'm using jQuerys form plugin on my pages. I'm going to try writing it out and see if that fixes anything. Any body ever experience a similar problem with this? In the mean time, is there a way I can check if any JS functions when I click on the radio button? Sorry if this is in the wrong forum, there's so many different languages involved, I hadn't a clue where to put it. Hey. I've been trying to get this page working with dynamically loaded iframe sources passed by URL, but I can't seem to get it working. Here's the relavent code: Code: <script type="text/javascript">
function delineate(str) {
URL = str.indexOf("=") + 1;
return(str.substring(URL))
}
</script>
Then there's a form/submit button that simply return the name of a type of item, for example "german" or "french" Using the form attributes method="link" and action="pageURL.html", where pageURL is the page that all of this is on. Code: <form name="hack"><input type="hidden" name="selector" /></form> <script language="javascript"> var url=window.location; document.hack.selector.value=url; var url_select=document.hack.selector.value; var selectedURL="../types/" +delineate(url_select) +".html"; document.write (selectedURL); frames['middleframe'].location.href=selectedURL; </script> <iframe id="middleframe" name="middleframe" src="../types/default.html" width="100%" scrolling="auto" height="1000" frameborder="0" style="display: inline;" /> I used the hidden form to change the url to text - advice from another website. I'm sure there are better ways to do it, but I'll explore them as soon as this thing actually works.. The types are in a subfolder named types, as shown. The document.write was placed in as a debug helper, and it displays the proper file location of whatever I select with the combo box, but the iframe doesn't change it's src to the selected page! I've tired the last line of the last <script> with several different methods, none of them producing any effect whatsoever. What am I doing incorrectly? Any help? Thanks.

help? i'm kind of dizzy right now since i've tried X different versions...still working on it. the new URL doesnt load i want to get the stud_id from the API and append it to the url that i launch in the iframe I read the "http://bodybrowser.googlelabs.com/body.html" page into an Iframe on my page. I now need to print the "viewcontainer" DIV that resides in the iframe. Accessing divs in an iframe is an issue with cross domain sources. Can anyone help me with a workaround or different idea? Thanks in advance!! I am looking for an input text that links to a iframe. . ? To begin, we need some simple HTML elements: A basic form; An Input text that will contain the URLs we want to use; An iFrame that will display the page we select from the input text. Thanks in advance Stickers I have a script which creates an element of iframe. I have a button which refreshes the iframe link. I need to do something to change a variable in the iframe src on every click of the button. I'll explain the real issue. I have a list of games I have with random name like, boomer.swf, kingdom.swf, balloon.swf and so on. So I somehow made this, Code: var r_text = new Array ();
r_text[0] = "boomer";
r_text[1] = "kingdom";
r_text[2] = "balloon";
var i = Math.floor(3*Math.random())
var gamedrome = { game: ""+r_text[i]+""};
Now I have a .js file which creates iframe element Code: function embed_game(params, options)
{
var data = [];
for(var i in params)
{
data.push(i + "=" + encodeURIComponent(params[i]));
}
data = data.join("&");
var frame = document.createElement("iframe");
frame.src = "http://website.com/embed/game.html?"+ data;
frame.style.width="100%";
frame.style.height="100%";
frame.style.border = "0";
frame.frameBorder = "0";
frame.id="newroom";
....
and another small script to refresh the inner iframe and not the page to change game. Code: <script type="text/javascript">
function Reload () {
var f = document.getElementById('newroom');
f.src = f.src;
}
</script>
It all works fine until the game is loaded, but the problem is that if once the game is loaded in site, the iframe source is already set and my button keeps loading the same game. I need to randomize it on every click. Please help me out. Hi, I try to change script source dynamically. When I use the following code, it works fine, and the script is executed Code: <script type="text/javascript">
document.write('<script src="http://gamestoenjoy.com/site/test.php"');
</script>
However when I use the following code, it doesn't work, the script isn't executed Code: <script type="text/javascript">
var url = "http://gamestoenjoy.com/site/test.php";
document.write('<script src=url>');
</script>
The only difference between the codes is that in the first code I use constant sting, and in the second code I use variable, in order to make the source dynamic. Please help me to solve this problem. Ok, 'nother head-banger for the hardcore! I have a "contact us" <a> with the id 'contact' on the main page, which is supposed to change the source file of an iframe to the contact page. Except when I click on "contact us" nothing happens. I've tried to get this to work several different ways, and suspect that the problem is purely syntax, but I just haven't been able to figure it out. Here's the code: The snippet on the main page (index.html): Code:
<div id="linkListContact" class="LinkList">
<img id="linkListContactBg" class="SideBarBgImg" src="Assets/Backgrounds/SideBar/ContactBg.png"></img>
<span>
<ul>
<li>
<div><a id="contact">Contact Us</a>
</div>
</li>
</ul>
</span>
</div>
... and the relevant Javascript: Code:
function setIFrame(frameSource)
{
document.getElementById('mainWindow').src = frameSource;
}
function setContactLink()
{
var contactURL = "http://katabasis.spreadshirt.com/shop/imprint"
document.getElementById('contact').onclick = new Function ( "setIFrame( 'contactURL' )" );
}
The setIFrame function is used to call the content initially when the page loads, and is working beautifully in that context. You can see the problem in action at the actual site: www.katabasis-apparel.com. Thanks. Hi! I want to insert flash player on my page, that user can change flv source. But I dont know how to make input field that change flv source. I tried to insert input field and button but dont know how to make it working, please help me Here is my flvplayer embed code: <script type="text/javascript" src="http://flvplayer.com/free-flv-player/flvplayer/swfobject/swfobject.js"></script> <div id="embed_player"> <h1>Please Upgrade Your Flash Player</h1> <p><a href="http://www.adobe.com/go/getflashplayer"><img src="http://www.adobe.com/images/shared/download_buttons/get_flash_player.gif" alt="Get Adobe Flash player" /></a></p> </div> <script type="text/javascript"> var flashvars = { flvpFolderLocation: "http://flvplayer.com/free-flv-player/flvplayer/", flvpVideoSource: "http://flvplayer.com/media/audi_tdi_commercial.mp4", flvpWidth: "640", flvpHeight: "375", flvpInitVolume: "50", flvpTurnOnCorners: "true", flvpBgColor: "#FFFFFF" }; var params = { bgcolor: "#FFFFFF", menu: "true", allowfullscreen: "true" }; swfobject.embedSWF("http://flvplayer.com/free-flv-player/FlvPlayer.swf", "embed_player", "640", "375", "9.0.0", "http://flvplayer.com/free-flv-player/flvplayer/swfobject/expressInstall.swf", flashvars, params); </script> I need to change the source of an image but I can't seem to figure out how. I believe that I have the correct syntax, but it does not seem to be working. Maybe I am typing it in wrong or something. I try to test my javascript by typing the script: <strong>javascript:document.getElementById('img1').src='./images/image1.jpg';</strong> into the address bar. Nothing happens. I also try to test it out by putting this on the page, but once again, nothing happens. Code: <script type="text/javascript"><!--
document.getElementById('im1').src="./scripts/'.$upload_image.'";
//--></script>
This is what my HTML code looks like: Code: <img src="./images/temp_wizard_picture.gif" alt="" style="padding:4px; background:#fff; border:1px #bbb solid;" id="img1" /> Can somebody please fill me in on what I am doing wrong. Thank you. Hi - I'm working in ASP.Net 2.0. My page has a GridView control, which is populated by a SQLDataSource. The GridView has one Button control per row. The button has a client-side javascript function (ShowDelete) attached to its OnClientClick event on DataBinding of the GridView. This event fires some javascript. The javascript does 3 things: - It changes the text of the button from "Hide" to "Create" - It changes the background color of the button from red to green - It assigns a new onClientClick event to the button: "ShowAvailable" The text and the color of the button change with no problem. After I change the OnClientClick event, I send an alert with the button's OnClientClick event and it reports it to be "ShowAvailable". However, when I click on the button, it doesn't fire ShowAvailable, it fires the original onClientClick event (ShowDelete). Also, when I do View Source, it shows the button's text, color and OnClientClick event as their original settings, i.e., "Hidden", "Red" and "ShowDelete", even though I'm looking at a green button that says "Create." What's going on here? Here's the code I use to attach the OnClientClick event on DataBinding of the GridView: Code: foreach (GridViewRow row in this.gvLocation.Rows)
{
if (row.RowType == DataControlRowType.DataRow || row.RowType == DataControlRowType.EmptyDataRow)
{
int rowindex = row.RowIndex + 1; //to exclude the header which is counted as a row when we get to javascript
btnAction.OnClientClick = "ShowDelete(" + rowindex.ToString() + "); return false";
}
}
Here's the javascript for ShowDelete: Code: function ShowDelete(rowindex)
{
var locationgridID = '<%= gvLocation.ClientID %>';
locationgrid = document.getElementById(locationgridID);
if (locationgrid != null)
{
action_cell = locationgrid.rows[rowindex].cells[3];
for (k = 0; k < action_cell.childNodes.length; k++)
{
if (typeof(action_cell.childNodes[k].id) == 'string')
{
action_cell.childNodes[k].value = "Create";
action_cell.childNodes[k].style.backgroundColor = "Green";
action_cell.childNodes[k].onclientclick = "ShowAvailable(" + rowindex + "); return false";
alert(action_cell.childNodes[k].onclientclick); // reports the OnClientClick event is ShowAvailable
}
}
}
}
Any thoughts are greatly appreciated! i have an iframe on my webpage and i am loading appropriate page in it by clicking appropriate button but when user logs out and at that time some page is opened in iframe corresponding to the login pages(like "edit profile") of user then at that moment i want to know that what page is loaded in iframe so that i close it(if it corresponds to pages of login like "edit profile") as user logs out and if it does not correspond to login pages then it remains as it is.For doing that i must know that what page is loaded in iframe and compare it in " if(condition){statement} in logout function" with the logion pages so that i know that if any of them is loaded in iframe and if loaded then close it.Can you help me with that by giving exact code example.

var cell_value = parseFloat(this_cell.firstChild.nodeValue);
// If it's a number (literally if it's not not not-a-number)
if (!isNaN(cell_value))

Hi, I have a site that runs a javascript slideshow automatically when a user visits it. It is designed in such a way that I cannot pre-load individual images for aesthetic reasons. (Also the whole concept makes my brain hurt.) I therefore need 1 of 2 things: 1. A preloader that doesn't show the page or start the slideshow until all the images are loaded. or 2. I could start with the slideshow paused, and when the page is fully loaded, the play command (currently attached to a 'play' button) is 'sent'. (I'm not techy, so this is the best I can do as explanation.) The latter would probably be more elegant, especially if ultimately I could hide the controls for the slideshow with a loading bar until all the html is loaded, and then show them when the slideshow starts. I'm sorry if this is a really basic question. I tried searching the site but couldn't find anything. If you do feel like answering, can you imagine that you are speaking to a 5 year old. Then dumb it down a bit. I need all the explanation and clarity I can get! Thanks! |
