JavaScript - Javascript Not Working In Iframe
I am having trouble with javascript code that is inside an iframe.
I am trying to simulate the w3School's tryit. I have tried setting the content of the iframe two different ways and got two different results. This is example code for what I want the iframe's content to be <html> <head> <script type="text/javascript"> function coordinates(event) { x=event.screenX; y=event.screenY; alert("X=" x " Y=" y); } </script> </head> <body onmousedown="coordinates(event)"> <p> Click somewhere in the document. An alert box will alert the x and y coordinates of the cursor, relative to the screen. </p> </body> </html> The first way which was successful (but not what i want) is to save the example code as example.html and set the src property of the iframe to that document. Everything works fine including the mouseEvent. The second way displays the example.html in the iframe as it should but it seems to be ignoring the javascript. This is how I set the iframe content: I have the code stored in a database table. I use xmlHTTPRequest to bring grab the code and it is stored in a variable called responseText. Frome here I the following code sets the iframe content. r = document.getElementById("iframe"); Doc = r.contentWindow || r.contentDocument; if(Doc.document){ Doc = Doc.document; Doc.open(); Doc.write(responseText); Doc.close(); alert(Doc.documentElement.innerHTML); } If anyone can can help me understand why the javascript code doesn't work the second way I would greatly appreciate it. Similar TutorialsHi All, Below mentioned code prints properly in Mozila but not in IE7 any help on this would be greatful. <HTML> <script Language="javascript"> function printfile() { for (var i=0; i<window.frames.length; i++) { //Mozilla parent.objAdobePrint.focus();-- Prints in Mozilla & not in IE parent.objAdobePrint.print();-- Prints in Mozilla & not in IE //IE // window.frames['objAdobePrint'].focus(); // window.frames['objAdobePrint'].print(); } } </script> <BODY> <iframe src="1.pdf" id="objAdobePrint" name="objAdobePrint" height="250" width="100%" frameborder=0></iframe><br> <input type="button" value="Print" onclick="javascript: printfile();"> </BODY> </HTML> Thanks, John I have some javascript code: first it gets string of the url in the address bar then it splits the string at the ? and grabs the right half it then makes an IFrame go to that string(which is yet another url I would manually insert) here is the code: Code: function redirect(){
var raw=window.document.location.href;
if(content_address_start=raw.indexOf("?")!=-1){
var content_address=raw.split("frame.html?")[1];
window.document.getElementById('content').src=content_address;
}
}
'content' is the id of the IFrame, and frame.html is the html file this code is inside. Ok, so everything works perfectly when I test this code offline, but as soon as I load it to my website, and the .src line occurs, it just loads a blank page in the IFrame. What could be causing this? Perhaps certain sites will not allow themselves to be inside iframes? Much thanks in advance. I hope I gave enough information and relayed my problem clearly. EDIT: It seems that the code works on other sites, just not youtube. Why would it do this and are there any ways around it? I am having difficulties with Internet Explorer and cannot find a solution online. The code in question is at http://www.blainegregson.com/news.php. The iFrame resizes for Firefox, Chrome, and Safari but not for IE. Also, I don't know javascript and thus found this code online. Here is the sample code: Code: <Script type="text/javascript">
function setIframeHeight(iframeName) {
var iframeEl = document.getElementById? document.getElementById(iframeName): document.all? document.all[iframeName]: null;
if (iframeEl) {
iframeEl.style.height = "auto";
// need to add to height to be sure it will all show
var h = alertSize(iframeName);
iframeEl.style.height =h + "px";
}
}
function alertSize(frameId) {
var myHeight = 0;
frame = document.getElementById(frameId);
if( typeof( window.innerWidth ) == 'number' ) {
//Non-IE
var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf("Firefox")).split("/")[1];
var FFextraHeight=parseFloat(getFFVersion)>=0.1? 16 : 0;
myHeight=frame.contentDocument.body.offsetHeight+FFextraHeight;
} else if( document.documentElement && ( document.documentElement.clientWidth || document.documentElement.clientHeight ) ) {
//IE 6+ in 'standards compliant mode'
innerDoc = (frame.contentDocument) ? frame.contentDocument : frame.contentWindow.document;
myHeight= innerDoc.body.scrollHeight + 10;
//myHeight = document.documentElement.clientHeight;
} else if( document.body && ( document.body.clientWidth || document.body.clientHeight ) ) {
//IE 4 compatible
myHeight = document.body.clientHeight;
}
//window.alert( 'Height = ' + myHeight );
return myHeight;
}
</script>
I hope I have this post in the right place! Any help would be very much appreciated... I have a feature on my website that allows users to choose the website background (using alternate css sheets) and then uses an externally linked javascript file to store the background choice as a cookie so it is consistent throughout the website. This works perfectly locally (i.e. when previewing my website on my computer) but now it is uploaded to my host it doesn't appear to be working. (with the same browser) My javascript is he http://www. b r p - e n v .com/javascript/backgroundchange.js (with no spaces) The website that the javascript file is linked to is http://www. b r p - e n v .com (with no spaces) In the head I have: <script type="text/javascript" src="../javascript/backgroundchange.js"></script> ...then I have: <body onload="set_style_from_cookie()"> ...and for users to choose which background: <form> <input type="image" src="../images/white-background-thumb.jpg" onclick="switch_style('bg1');return false;" name="theme" value="White" id="bg1"> etc... </form> My problem is: The background reverts back to the default when moving to a different page. This would indicate that the background choice is not being saved in cookies. But this works locally! I have tried putting the javascript directly onto each page but I still had the same problem. I hope someone can help, I will be so grateful if I can get this to work. Many thanks indeed! Hello all, my second post! I finally got the below script working in Firefox and was really pumped about it until I realized it didn't load in Google chrome or Safari. What this script does is its a dual onclick event which makes a hidden div appear and loads an iframe within the now visible div. Here is the code, I would love any input on how to make this work in other browsers. Here is the header code: Code: <SCRIPT type="text/javascript">
<!--
var state = 'none';
function showhide(layer_ref) {
if (state == 'block') {
state = 'none';
}
else {
state = 'block';
}
if (document.all) { //IS IE 4 or 5 (or 6 beta)
eval( "document.all." + layer_ref + ".style.display = state");
}
if (document.layers) { //IS NETSCAPE 4 or below
document.layers[layer_ref].display = state;
}
if (document.getElementById &&!document.all) {
hza = document.getElementById(layer_ref);
hza.style.display = state;
}
}
//-->
</script>
<SCRIPT type="text/javascript">
function loadIframe(iframeName, url) {
if ( window.frames[iframeName] ) {
window.frames[iframeName].location = url;
return false;
}
else return true;
}
</script>
Here is the code on the page where a link click shows the hidden div and loads the iframe contained. Code: <p><a href="#" onclick="showhide('div1');return loadIframe('ifrm1', 'http://www.google.com');">show/hide me</a></p>
</td></tr>
<div id="div1" style="display: none; position: fixed; z-index:4; width: 1010px; height: 500px; left: 5%; top: 15%; background-color: #f0f0f0; border: 1px solid #000; padding: 10px;"><iframe name="ifrm1" id="ifrm1" width="100%" height="90%" scrolling="yes" frameborder="0">Sorry, your browser doesnt support iframes.</iframe><p><a href="#" onclick="showhide('div1')">close</a></div>';

I want the onclick="javascript:NavPage to change the iframe which is currently google.com to a specific page. in this example it would all_rooms_today.html. So I need to write the javascript function Navpage that fills the iframe named internal. Thanks Hello, If JavaScript is disabled, does the content in an iframe become un-viewable/ blocked? This is in general, regardless of how safe or trusted the website/ content is. Code: <html> <head> <noscript>Javascript is disabled. Having it enabled provides the greatest functionality.</noscript> </head> <body> <noscript>Javascript is disabled. Having it enabled provides the greatest functionality.</noscript> <iframe src="first.html" width="300" height="300" /> </body> </html> Hello I'm having a little trouble. So far I've been able to achieve that when the user clicks on a button, they're be redirected to a random url. (this is from a list of different urls) I can't get it to work so when the user clicks on the button, they're be directed to the url through an iframe and not just loading a new page. I'm awful at explaining things so I donno if you's will understand me! index.html Code: <form name="myForm" id="myForm"> <p> <input type="button" name="myButton" value="url" onclick="rand_link()" /> ................ <iframe id="frame" src="iframe.html" width="100%" frameborder="0" marginheight="0" marginwidth="0"></iframe> ........ url.js Code: function go_to(url) {

a = 1+Math.round(Math.random()*2);

The problem is i dont understand how in page 1, you are direct to page 2. Can anyone please explain to me how this is working? I am new with javaScript. Trust me, i have looked and i am still learning. This is important to me. -Mygel hi, Guys can u help me currently iam running clicksor ads on my blog but its decrease page load time and page stuck where javascrip is located can u help me . how can i put this javascript in iframe so that this javascript loads but never stuck the page thanx Regards Fawad Hello, I would like to know which statement I should use in order to echo an iframe in JS. Thanks, Ben Hi, new to the forum (and Javascript coding). I hope someone can help as this is driving me nuts... I want my website to display the content of another webpage in an iframe. the other webpage extension will change each day (e.g. 'www.example.com/16_02_2012.html' would be today's file to view, 'www.example.com/15_02_2012.html' would have been yesterday's etc.). I have worked out some code to grab today's date and create the web address as a variable. how do i then use that variable in the <iframe src="??"> when someone click a link to "update the iframe"? Here is my code so far... I would really appreciate some help!!! :s <html> <script> function getMonth() { var now = new Date(); var month = now.getMonth(); return month < 10 ? "0" + (month+1) : month+1; } function getDay() { var now = new Date(); var day = now.getDate(); return day < 10 ?

There is more to the script this is just my test for the iframe, what i have is groups, all accounts are grouped in groups, when a group is clicked, i am prompt with Enter raid ID, i enter the raid ID and the frames for how ever many people in that group load, on those pages that load in the iframe is a raid page with a captcha to join the raid, the captcha shows automatically in the frame but it is not perfectly aligned as i want it to be. I use dreamweaver and can debug in my browser, any help is appericiated, i can also post pictures as to what i am talking about. EDIT: i also forgot to say i am new to javascript, i know html and php very well.. MrGato =D I am trying to run javascript within Iframe and its not running. (The bigger pictu The final target is to do a file upload without refreshing the page, and the original code is using the iframe as the target of the form, and the return from the server is a javascript code that should update some status field on the page. However the code return from the server is not running, so I just paste it in the iframe and it is still not running. ) Code: Content-type: text/html\n\n

A few weeks ago, I posted a request for a basic script that I could use to load bible references into the browser depending on the current date (1 reading/week) as part of my Duke of Edinburgh award scheme project - I'm 15 and have started helping out with the local church website as part of my community service for the award. I know the basics of html, and a very little bit of Javascript/C++ When I posted the request, I was very quickly provided with a script that I am very grateful for, from Philip M (I think). We have just decided to attempt to implement the script into the website, and I am struggling a little bit with using Iframes in Javascript. Is there any possibility that somebody could give me a hand? (The test week is currently 49). The code works perfectly aside from the iframe loading. Code: <html>
<head>
<script type = "text/javascript">
function showWeekText() {
var texts = new Array(54); // array index starts at 0 which is unused
texts[1] = "Iframe for Week 1";
texts[2] = "Iframe for Week 2";
texts[3] = "Iframe for Week 3";
texts[4] = "Iframe for Week 4";
texts[5] = "Iframe for Week 5";
//6-48 removed for ease of viewing
texts[49] = <iframe src ="http://mobile.biblegateway.com/passage /index.php?search=matthew%203:1-6&version=NIV" width="90%" height="4 <p>Your browser does not support iframes.</p> </iframe>";
// Iframe i wish to use for week 49 (Iframe works in an empty html page, but unsure how to use in javascript script)
<iframe src ="http://mobile.biblegateway.com/passage/index.php?search=matthew%203:1-6&version=NIV" width="90%" height="4 <p>Your browser does not support iframes.</p> </iframe>";
texts[50] = "Iframe for Week 50";
//texts[51]-[53] removed for easier viewing
Date.prototype.getWeek = function() {
var onejan = new Date(this.getFullYear(),0,1); // month 0 is January
return Math.ceil((((this - onejan) / 86400000) + onejan.getDay()+1)/7);
}
var today = new Date();
var weekno = today.getWeek();
var weektext = texts[weekno];
document.getElementById("myweek").innerHTML = weektext;
}
</script>
</head>
<body onload = "showWeekText()">
<div id = "myweek"></div>
</body>
</html>
hello! i created a javascript for opening a page on a new window and added it on an html file. i then used the said html file as the source of my iframe on a joomla page. but the javascript isnt working. any help? the said iframe is called Scroll News on this page: http://dumplingdesigns.freehostia.com/ 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 All, I have html pages with code like <div> <script type="text/javascript" src="http://myserver2/mysite/addhtm.js"></script> </div> the script adds some html code and random images selected from second server inside an iframe tag in the div tag. I need to examine this added html and image properties in my page using javascript. A search on internet did not help, it says elements inside iframe coming from different domain can not be accessed. Is there any workaround or hack available to access iframe contents from page javascript? Thanks |
