I am using external javascript to populate a popup when a page is loaded in my website. Like the below.
<script type='text/javascript' src='https://www.website.com/some_website_javasciprt_filt'></script>
The javascript above not only create a popup but also create a hidden iframe.
pgmr_ifrm = document.createElement('iframe');
pgmr_ifrm.id = 'pg_merchrev_track';
pgmr_ifrm.style.position = 'absolute';
pgmr_ifrm.style.left = '1px';
pgmr_ifrm.style.visibility = 'hidden';
pgmr_ifrm.src='https://d2iz0h6pqiasve.cloudfront.net/images/spacer.gif';
body.insertBefore(pgmr_ifrm,bodyfirstchild);
The problem is that the iframe stays on webpage even though I close the popup and blocks my menu buttons.
Is it possible to set the position of the iframe after the page load so that it does not block my buttons?
Thank you.
Try
$(document).ready(function() {
pgmr_ifrm = document.createElement('iframe');
pgmr_ifrm.id = 'pg_merchrev_track';
pgmr_ifrm.style.position = 'absolute';
pgmr_ifrm.style.left = '1px';
pgmr_ifrm.style.visibility = 'hidden';
pgmr_ifrm.src='https://d2iz0h6pqiasve.cloudfront.net/images/spacer.gif';
body.insertBefore(pgmr_ifrm,bodyfirstchild);
});
This will do all the code after the page has loaded.
Actually, I found much easier way of doing it.
Instead of dealing with javascript, I simply set the z-index in CSS.
Problem solved.

I am automating a process wherein I have to login to website and download only the CSV files from the different types of files.
My jQuery code is getting executed in the console but not getting executed after integrating with HTML. Please find the jQuery code below :

EDIT: I was, indeed, off-base with this. Didn't read your code carefully.
leaving this here for historical purposes...
I might be completely off-base with my assumptions here, and apologize in advance if this is the case. That said, it really looks like you are trying to load a page inside an IFrame and use jQuery outside of the IFrame to read data from inside the IFrame.
Long story short: you cannot use jQuery (or any javascript, or, indeed, ANYTHING AT ALL, if the browsers are working as they should) to manipulate or read content that is inside an IFrame, from outside the IFrame, if that IFrame has a src tag.
You can only manipulate / read from iframe you have built from scratch by yourself. This is by design, and for an important security reason. If you want to use IFrame to display a page, you are severely restricted to only show the page to user as-is.
If my assumption was correct, you need to either:
Get your JavaScript embedded (nicely) into the page you are now loading in your IFrame or
Use an AJAX call to get the contents of that page into your current page's memory context. This will probably mean jumping through some hoops if you really want to use jQuery to find all the elements you want.
...or, you may be able to create an empty IFrame, put the content you got from the AJAX call into that IFrame along with your Javascript, and get it to work. maybe. Not sure about this one.
can you please try with this? replace your window.createElement with document.createElement .
$(document).ready(function() {
$('.ibody tr').each(function(a, b) {
var count = 0;
var name = $('.cl', b).text();
if (name.indexOf(".CSV") !== -1 && name.indexOf("TAS") !== -1) {
var d = a - 9;
var hiddenIFrameID = 'hiddenDownloader' + count++;
var iframe = document.createElement('iframe');
iframe.id = hiddenIFrameID;
iframe.style.display = 'none';
document.body.appendChild(iframe);
iframe.src = "https://www.shipper-ml.com/viewReports.do?ctrl=reportListForDownload&action=DownloadReport¶m=" + d;
}
});
})
I have the following code in my document:
<a class="twitter-widget" href="url" data-widget-id="138843679974442730">Twitter Timeline</a>
<script>!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0],p=/^http:/.test(d.location)?'http':'https';if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src=p+"://platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");</script>
data-widget-id is connected to one style. Right now if there is a theme change on the website (I replace all responsible stylesheets and images) everything changes but the Twitter widget.
Since the widget itself is an iframe, I can't change any stylesheets attached to it.
Is there an easy way to change the style of the widget without reloading it (deleting the tag, creating the tag, running js)?
You can style elements in the Twitter widget iframe using JavaScript.
First, you need the active document in the iframe's nested browsing context:
var doc = document.getElementById("twitter-widget-0").contentDocument;
Then, you can apply styles (e.g.):
doc.querySelector(".timeline-header").style["background-color"] = "black";
doc.querySelector(".timeline-header a").style["color"] = "white";
Example: http://codepen.io/smockle/pen/IJHnj
There is no straight forward way of doing this, so I've decided to bring in another dependency that will be delaying the onload event..
<script type="text/javascript" src="//platform.twitter.com/widgets.js"></script>
And here is the code that did the job:
var twitterBox = document.getElementsByClassName("twitterBox");
if (!twitterBox || twitterBox.length == 0) { return true; }
var twitterTimeline = document.createElement('a');
twitterTimeline.className = 'twitter-timeline';
twitterTimeline.href = 'url';
twitterTimeline.innerHTML = 'Twitter Timeline';
twitterTimeline.setAttribute('data-widget-id', '388742673974046720');
twitterBox[0].removeAttribute('data-twttr-id');
twitterBox[0].innerHTML = '';
twitterBox[0].appendChild(twitterTimeline);
twttr.widgets.load();
I have 2 iframes in my page. Both have the same source. When I change the 1st iframe, the changes must be reflected in 2nd one. It looks like remote browsing. How can I achieve this in javascript?
var iframes = document.getElementsByTagName('iframe');
var src = iframes[0].src;
iframes[1].src = src;
Without knowing what your page does or seeing any code can't really give you more then this...
If you're using jQuery:
var frames = $('iframe');
frames.each(function() {
this.attr("src", yourUrl);
});
I know this has probably been answered multiple times before, but this is the second time I've worked with JQuery, and I'm not entirely sure what I need to do, since I'm not familiar with this format of coding. I've looked at other, similar, questions, but none of the answers are making sense to me, and I really need this to click in my head so I can keep working.
I'm using Jpopup for this, so the script info is all there, but my question is this:
I have two areas in an image that I need to be clickable, both showing different content, but I can only call one page at a time to pop up, and multiple anchor tags just give me the same content twice. What do I need to add to that script to allow the page to show two different popups?
This is the script in my HTML page
<script language="javascript">
$(document).ready(function() {
//Change these values to style your modal popup
var source = "demo.html";
var width = 920;
var align = "center";
var top = 100;
var padding = 10;
var backgroundColor = "#FFFFFF";
var source = 'popups/demo.html';
var borderColor = "#000000";
var borderWeight = 4;
var borderRadius = 5;
var fadeOutTime = 300;
var disableColor = "#666666";
var disableOpacity = 40;
var loadingImage = "popups/loading.gif";
//This method initialises the modal popup
$(".modal").click(function() {
modalPopup( align,
top,
width,
padding,
disableColor,
disableOpacity,
backgroundColor,
borderColor,
borderWeight,
borderRadius,
fadeOutTime,
source,
loadingImage );
});
//This method hides the popup when the escape key is pressed
$(document).keyup(function(e) {
if (e.keyCode == 27) {
closePopup(fadeOutTime);
}
});
});
</script>
The HTML
<div style="margin-top:200px;margin-left:395px;">
<a class="modal" href="javascript:void(0);"><img src="images/clickmelarge.png" border="0">
</a></div>
I studied the source code of the "plugin" and studied also the invoked source code of the HTML page at runtime. In my eyes this popup plugin doesn't support multiple popups at same time. Why?
Well, I used Firebug to exermine the source code at runtime and I saw only the same divs, added to the DOM tree by this. As far as I did understand when the DOM was complete loaded the author added the main divs to the DOM tree and set they all to 'hide'. If you call your function these divs will set to 'visible'.
Another reason is -in my eyes a very tricky way- the div with the Id 'blockModalPopupDiv' covers the full browser window. If you click on this element, the function of hiding all divs will be executed. You won't be have chance to click outside the div element.
So what can you do?
I think you have only three options :
Ask the author for an opportuniti to add your requirement.
Download the source code and modifiy it your self. Its created in standard Javascript.
Try to use another plugin or change your concept.
I'm currently developing a Toolbar from Google Chrome. Basically it's a toolbar that i'm injecting in every web pages by using a Content-Script. Technically the toolbar is materializd by a iframe that include all the components like button, dropMenu,... Here is the script you make this :
// Take down the webPage
document.getElementsByTagName('body')[0].style.marginTop = '39px';
var body = $('body'),
toolbarURL = chrome.extension.getURL("yourtoolbar.html"),
iframe = $('<iframe id="YourToolbarFrame" scrolling="no" src="'+toolbarURL+'">');
// Insertion
body.append(iframe);
// Effect
$("#YourToolbarFrame").hide().fadeIn(800);
But right now i'm trying to add some component on this iframe for example a button but it didn't work...
var yt = $("#YourToolbarFrame");
var newButton = $('<input type="image" src="images/pop.ico" name="InstantMessage" width="23" height="23">');
yt.append(newButton);
The body of the iframe look like this :
<body>
<div class="default">
// COMPONENTS
</div>
</body>
Hope someone can provide me some help ! :)
You have to wait until the iframe loaded. E.g.:
iframe.load(function() {
var newButton = ...;
$(this).contents().find('body').append(newButton);
}).appendTo('body');
Not sure how Chrome handles the same-origin policy for content scripts though.
Since you're using jQuery, you could try using
$('#YourToolbarFrame').contents().find('body').append(newButton);
Or if you don't want to append to the body directly, use any other element in the find() statement.
