Please bear with me if i'm asking something very basic as I don't know much about coding. I have a stock charting application which has a built-in web browser. I configured this browser to load a html page, which i coded as below, like this mypage.html?symbol=xzy, What i am trying to do here is to capture the submitted html variable, 'symbol' and use its value as part of the url string to load a portion of another third party webpage. I can't figure out what's wrong with my javascript code that is failing to set the value of the 'src' attribute. Any help is most appreciated.
<html>
<header>
<script>
document.getElementById('iframe').src = "http://www.asx.com.au/asx/markets/dividends.do?by=asxCodes&asxCodes="+symbol+"&view=all#dividends";
</script>
</header>
<body>
<div id="dividends"></div>
<iframe id="iframe" src="" style="display:hidden;margin-left: -140px; margin-top: -33px" scrolling="no" frameborder="no" width="398" height="265"></iframe>
</body>
</html>
try move the script after html DOM
<body>
<div id="dividends"></div>
<iframe id="iframe" src="" style="display:hidden;margin-left: -140px; margin-top: -33px" scrolling="no" frameborder="no" width="398" height="265"></iframe>
</body>
<script>
document.getElementById('iframe').src = "http://www.asx.com.au/asx/markets/dividends.do?by=asxCodes&asxCodes="+symbol+"&view=all#dividends";
</script>
A couple of things: 1) start with performing the function onLoad - that way you know the script will run and popluate the src attribute after the browser renders it, and not before.
2) use a function to get the url value.
<html>
<header>
<script>
<!-- source: http://javascriptproductivity.blogspot.com/2013/02/get-url-variables-with-javascript.html -->
function GetUrlValue(VarSearch){
var SearchString = window.location.search.substring(1);
var VariableArray = SearchString.split('&');
for(var i = 0; i < VariableArray.length; i++){
var KeyValuePair = VariableArray[i].split('=');
if(KeyValuePair[0] == VarSearch){
return KeyValuePair[1];
}
}
}
function SetContent(){
var symbol = GetUrlValue('symbol');
document.getElementById('iframe').src = "http://www.asx.com.au/asx/markets/dividends.do?by=asxCodes&asxCodes="+symbol+"&view=all#dividends";
}
</script>
</header>
<body onLoad="SetContent();">
<div id="dividends"></div>
<iframe id="iframe" src="" style="display:hidden;margin-left: -140px; margin-top: -33px" scrolling="no" frameborder="no" width="398" height="265"></iframe>
</body>
</html>
Move the javascript to the bottom of the page AFTER the iframe. You are trying to change an element before it is created. Also do src="about:blank" initially, so it validates.

I want to hide an element inside an <object> tag , the element is <div class="footer">...</div> I tried this code but still not working, please help me
<div>
<object id="t" type="text/html" data="https://www.example.com/" width="100%" height="600px" style="overflow:auto;">
</object>
</div>
and this is my javascript code
<script>
$(document).ready(function(){
var t = document.querySelector("#t");
var htmlDocument = t.contentDocument;
htmlDocument.getElementsByClassName("footer")[0].style.visibility='hidden';
});
</script>
Thank you I fixed it (hide the footer of example.com inside my website) by using an iframe and css following this code :
<div style="overflow:hidden;">
<iframe src="https://www.example.com/" name="iframe_all" frameborder="0" style="width: 100%; height: 650px; margin-bottom: -120px;" ></iframe>
</div>
I am trying to access the body of the document from an iframe.
I the body I want to get the src value of another iframe.
<iframe src="https://putstream.com/movie/oblivion?watching=RaHP6KwPJ8prB0MfMlhJiYYwW" allowfullscreen="true" webkitallowfullscreen="true" mozallowfullscreen="true" style="height: 820.5px;">
#document
<html lang="en">
<head><style class="vjs-styles-defaults">
</head>
<body>
<iframe id="openloadIframe" allowfullscreen="" webkitallowfullscreen="true" mozallowfullscreen="true" style="width:100%;height:100%;" src="https://openload.co/embed/bbhP94t0548"></iframe>
</body>
</html>
My Attempts:
var oiframe = document.getElementsByTagName('iframe')[1]; //accessing the first iframe
var sif = oiframe.getElementById('openloadIframe').src; //getting the actual content
var ifc = oiframe.contentWindow.getElementById('openloadIframe').src; //at this point I just tried to get it working
var ifhtml = oiframe.contentWindow.document.body.innerHTML.getElementById('openloadIframe').src;
None of these work and I found nothing else how I could access the content of #document.
I dynamically create a pdf in a iframe:
<iframe name="output" id="output"></iframe>
and try to print from it:
window.frames["output"].focus();
window.frames["output"].print();
But how you can see in this example:
http://jsfiddle.net/FEvq6/78/
It prints a blank site.
It prints blank page because you're printing the iframe itself. Here is what you should do:
1. The iframe should contain EMBED tag which will load the PDF (for some reason stack overflow did not formatted code well, please see paste bin link below):
< embed src="path_to_script_which_generates.pdf" type="application/pdf" id="pdf"
width="100%" height="100%">
< /embed>
2. Then you should call the EMBED object to print the document. But since it may require some time for it to load you would need a timeout:
var doPrinting = (id){
var pdfObject = document.getElementById(id);
if (typeof(pdfObject.print) === 'undefined') {
setTimeout(function(){ doPrinting(id); }, 1000);
} else {
pdfObject.print();
}
}
doPrinting('pdf');
Here is paste bin of the above: http://pastebin.com/s6qSTE8t
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
</head>
<body>
<strike>funny</strike>.
<iframe src="file_to_print.pdf" class="frameSet" type="application/pdf" runat="server" name="I5" scrolling="yes" width="100%" height="400"> </iframe>
</body>
</html>
I have two iframes in my web page, and I want to load the second iframe after the first iframe has finished loading. How can I do this? I tried using the settimeout function, but I encountered some problems.
This is my code:
<iframe src="firstiframe" frameborder="0" widht="100%" marginheight="0" marginwidth="0" scrolling="NO" id="the_iframe">
</iframe>
<iframe src="secondframe" frameborder="0" widht="100%" marginheight="0" marginwidth="0" scrolling="NO" id="the_iframe2" >
</iframe>
<script>
function resizeIframe(iframeID)
{
document.setTimeout("resizeIframe",1000);
var iframe = window.parent.document.getElementById(iframeID);
var container = document.getElementById('content');
iframe.style.height = container.offsetHeight + 'px';
}
</script>
You can use the jQuery ready function on the frame to see when it's loaded and then set the src url for the second frame. Something like:
$('#firstframe').ready(function() {
$('#secondframe').attr('src', 'http://yourlink');
});
You can do something like this:
$("#firstIframe").load(function (){
$("#secondIframe").load();
});
I would do this with jquery:
First iframe:
<iframe id="iframe1"></iframe>
<div id="loadsecondIframeHere"></div>
<script>
$('#iframe1').ready(function(){
$('#loadsecondIframeHere').html('<iframe id="iframe2"></iframe');
});
</script>
or use $(document).ready()
I'm trying to create a separate $$ function for like a iframe scope and to do that I need to use the function like this, this is what I have tried
HTML:
<iframe src="" frameborder="0"></iframe>
JAVASCRIPT:
var $$ = function( html, attributes ) {
var context = $('iframe')[0].contentDocment;
return $(html, attributes, context);
}
Usage:
$$('<h1>', {text: 'Hello'}).appendTo('body');
So I should end up with this result
<iframe src="" frameborder="0">
#Document
<html>
<head></head>
<body>
<h1> Hello </h1>
</body>
</html>
</iframe>
But instead I end up with this result.
<iframe src="" frameborder="0"></iframe>
<h1> Hello </h1>
Any Advice?
JSFiddle: http://jsfiddle.net/77VED/1
How bout simply doing something like this?
$("iframe").contents().find("body").html('YOURCONTENT');
or
$('<h1>', {text: 'Hello'}).appendTo($('iframe').contents().find('body'));
Btw. this is a possible duplicate of this
