I have some problems with including an PDF on an JSF site. I'm using pdfobject (http://pdfobject.com/) but it does not work out the way I want. I can't adjust my settings for my desired outcome, where there is a unscrollable, scaled document (so that it fits the frame) shown in a frame with width = 595px & height = 842px. I tried until now:
<script type="text/javascript" src="pdfobject.js"></script>
<script type="text/javascript">
window.onload = function() {
var myPDF = new PDFObject({
url : "ls_v7.pdf",
width: "595px",
height: "842px",
pdfOpenParams : {
page: 1,
view : 'FitB'
}
}).embed("pdf");
};
</script>
[...]
<div id="pdf">
It appears you don't have Adobe Reader or PDF support in this web
browser. Click here to download the PDF
</div>
or also
<object data="ls_v7.pdf#page=1&view=fitH"
type="application/pdf" width="595" height="842"> </object>
I think I tried most of the cases mentioned in this document, but where not able to come up with the right solution. (The oucome is always a frame with scroll-bars & the PDF gets always shown in full size)
Some background information:
I first included an PDF with iFrame on a JSF page, what went very well. But the Problem is, that on IE8 (some of the client machines) does not show them. So I went to this approach, if you would suggest to try another framework/etc. I would be also very greatful.
it's best to use CSS to specify exact size of the wrapper element.
PDFObject expands the PDF to 100% width/height of the parent container, so wrap your PDF in a div then size the div using CSS.
See this example: http://pdfobject.com/examples/simplest-styled.html

I have looked over examples online, yet I believe I am overlooking something. I have two similar images that need to be rendered when the screen is at a different size. One image at 1440px screen size and one at 375px screen size. Right now with my code I have set the initial source to render the "mobile view" of the image, and with the srcset of the desktop view image at 1440w. When I load up live server it shows the desktop image, and not the initial source of the mobile view. So it seems to be working but missing a step.. any tips are greatly appreciated!
<img
class="future__container--img"
src="./images/illustration-editor-mobile.svg"
srcset="./images/illustration-editor-desktop.svg 1440w"
alt="illustration-editor-mobile"
/>
So when the browser first loads it is showing the desktop.svg, but when I set the browser to 375px it still displays the desktop.svg. I first had this written in javascript ..
const resizeEditiorImg = () => {
const reswidth = screen.width;
let image = document.querySelector(".future__container--img");
if (reswidth >= 1440) {
image.src = "../images/illustration-editor-desktop.svg";
} else {
image.src = "../images/illustration-editor-mobile.svg";
}
};
window.addEventListener("resize", resizeEditiorImg);
But the issue here is that when the browser first loads on desktop view, it is displaying the mobile image unless the user manually resizes the browser, which is what I believed at first. I hope this post makes sense!
This only work in resize browser because this code resizeEditiorImg
you need run this command resizeEditiorImg in your load page.
example
<body onload="resizeEditiorImg()">
I installed a SSL trust logo onto my website – the following code is what displays the logo:
<script language="JavaScript" type="text/javascript">
TrustLogo("https://www.(mywebsite).com/comodo_secure_seal_76x26_transp.png", "CL1", "none");
</script>
I needed it to be fixed on the bottom left corner of my page, so after a lot of trial and error I settled with the following code:
img:not(main img) {
position: fixed;
bottom: 0;
left: 0;
The problem is, this isn't really targeting the specific image that needs to be targeted. The bigger problem is that this does not work on any other browser other than the browser I had originally tested (Safari). (Maybe it's because the 'img' tag is not appropriate targeting?)
How can I target this logo? (If not through CSS, how can I make it fixed?)
Safari (the CSS works here)=>
Chrome (CSS does nothing)=>
This worked for me:
Do not use img to target the logo – use one of the image's attrributes to be as specific as possible.
Try something as simple as the src attribute:
[src="https://www.(mywebsite).com/comodo_secure_seal_76x26_transp.png"]
You can also use a node inspector to view more useful information to help you pinpoint the image.
I have the following code on my site that's supposed to show a popup window
<span class="fbridge-signup-form" data-widget-id="21378"></span>
<script type="text/javascript">
(function() {
var secure = ("https:" == document.location.protocol);
var fb_js_host = (secure ? "https://www.fanbridge.com" : "http://widget-platform.fanbridge.com");
window._FBRIDGE_WIDGETS_HOST = fb_js_host; var p, s, id = 'fbridge-widgetjssdk-v1';
p = document.createElement('script'); p.id = id; p.type = 'text/javascript'; p.async = true;
p.src = (secure ? "https://ssl.fbridgecdn.net" : "http://static.fbridgecdn.net") + '/js/fb/widget/v1/platform.js?_=' + ((new Date()).getTime());
s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(p, s);
})();
</script>
It works fine, but the problem is that there's some setting with lightboxes on my Drupal site that makes this window of a smaller width and height than the actual content inside.
I tried getting the element with getElementByClassName or writing the width and heightparameters into the style property of fbridge-signup-form but it didn't work out.
Do you know what I could do to force it to be a certain width and height? Say 480px by 400px?
You can check the actual page on http://waytorussia.net/Moscow/Intro.html (it has a cookie set to show only once).
UPDATE: maybe it's possible to use another kind of popup so this one is not overridden by my other settings?
According to the HTML source, the element you should resize is (id) cboxContent.
But the black frame around it doesn't seem "ready" (from an HTML/Css point of view) to be resized.
See the screenshot here:
I resized it 400x400.
EDIT -
By resizing all the appropriate elements, you can manage to get what you want. Here's an example done manually:
Just inspect the element (right-click > Inspect) with a modern browser, and look at the divs that you need to resize on load (with JavaScript).
i opened your page in Firefox with the developer tools to see how things work width and height wise and the results are interesting.
Basically the frame of the lightbox is made up of numerous divs all seem to be hard coded to a specific width and height. When you hover over the inner content using the inspector tool you can see that the inner content is actually the correct width and height but the container ( your collection of divs is not )
Try expanding the height and width of the container divs using css maybe??
I wouldnt have used this as answer but unfortunately i cant provide screenshots using just the comments section to my knowledge.
To see the image at full screen open it in a new tab.
For a good alternative try colorbox its a great JQuery modal plugin that can be used for just about anything.
Demos are here. Have a look at inline HTML example it seems to be similar to what you need.
Thanks to #Vincent G and #KyleT for their help I found that I had to edit the CSS styles for colorbox module.
#cboxLoadedContent iframe{display:block; min-width: 480px; min-height: 400px; border:0;}
and
#colorbox{min-width: 480px !important; min-height: 400px !important; }
in the colorbox.css file which was part of my Drupal installation.
After that the widget was loading fine.
I'm having a very strange occurrence when using an IFrame and jQuery.Contents.
We have a number of reports that are built in seperate pages, and a display page that uses jQuery Tabs to display a number of these pages at once.
These reports are of varying sizes based on the data and the inputs by the user, since they can vary we needed to dynamically set the height of the IFrame to be the height of the contents. To get the height of the contents I am using this following code :
var iframeHeight = $(this).contents().height();
iframeHeight += 50;
console.log(iframeHeight);
This code works fine on first load, but after the IFrame Postsback/Refreshes the iframeHeight that is logged is always 83px more than the previous height, regardless of the actual contents of the child page.
i.e. First report is 500px high,
Second report should be 300px high
but $(this).contents().height(); returns 583px.
Here is an example jsFiddle to demonstrate the problem. If you open the console and then click the JSFiddle Icon in the top left of the IFrame, you will notice that the logged height will be 83px more than the previous.
Is there anything that could explain this issue?
Am I miss-understanding how the jQuery.Contents function works?
If this will not work this way is there a better way to get the content height? (I've tried the height of the body + the height of the form object but this didn't work in IE).
Tested this in IE10 + Chrome Version 31.0.1650.57 m
Here is an implementation that seems to work (for expanding/shrinking contents..)
assuming that iframe's src is from the same domain and that there are not scripts that resize the iframe's contents once loaded
$(document).ready(function() {
$('#frameID').on('load', function () {
$('#ReportBuild').hide()
$(this).show();
var iframeHeight = $(this.contentDocument.documentElement).outerHeight(true);
$(this).css({ height: iframeHeight + 'px' });
this.contentWindow.onbeforeunload = function () {
$('.tabFrame').hide();
$('#ReportBuild').show();
}
});
});
Demo at http://jsfiddle.net/rq5S5/8/
With help I managed to finally find a solution, suggested examples worked on JSFiddle's but would not work when applied to my issue using ASP.NET controls generated on PostBack.
To handle this, on each of my Child pages I have wrapped the entire content inside a <div></div> and retrieved the height of this element.
Example :
<div id="ReportContent">
<!-- HTML Content -->
</div>
And the jQuery Code :
var iframeHeight = $(this).contents().find('#ReportContent').outerHeight(true);
This now works correctly for my problem in both IE10 and Google Chrome Version 31.0.1650.57 m
Is it possible to load a background-image asynchronously?
I've seen many jQuery plugins to load normal image in an asynchronous way, but I can't find if it's possible to preload / asynchronously load a background-image.
EDIT
I clarify my problem. I've been working on this test site http://mentalfaps.com/
The background image is loaded randomly from a set of images refreshed each hour by a chron job (which takes random images on a flickr catalog).
The host is free and slow at the moment, so the background image takes some time to load.
The positioning of the first overlay (the one with the PNG transparent mentalfaps logo) and width are regulated by a function created in the jQuery(document).ready construct.
If you try to refresh the page many times, the width of the right overlay div is 0 (and so you see a "hole" in the layout)
Here is the method to set my positions:
function setPositions(){
var oH = $('#overlay-header');
var overlayHeaderOffset = oH.offset();
var overlayRightWidth = $(window).width() - (overlayHeaderOffset.left + oH.width());
if (overlayRightWidth >= 0) {
$('#overlay-right').width(overlayRightWidth);
} else {
$('#overlay-right').width(0);
}
var lW = $('#loader-wrapper');
lW.offset({
left: (overlayHeaderOffset.left + oH.width() - lW.width())
});
}
The problem is that the $(window).width() is lower then the effective window width! so the check fails and the script goes for $('#overlay-right').width(0);
any ideas?
Not sure whether I really understand your question, but background images (and all other images) are already loaded asynchronously - the browser will start separate requests for them as soon as it encounters the URL while parsing the HTML.
See this excellent answer for background on loading order: Load and execution sequence of a web page?
If you meant something else, please clarify.
The trick to loading something in the background is to load it once, so the next time when it is loaded it already is in the cache.
Put the following at the end of your html:
<script>
var img = new Image();
img.onload = function () {
document.getElementsByTagName('body')[0].style.backgroundImage = 'background.png';
};
img.src = 'background.png';
</script>
You could use a prefetch link in the head.
<link rel="prefetch" href="/images/background.jpg">
You should be able to add these links to the head via JavaScript.
I like to use CSS to fill the background with a color for page load.
After DOM ready event, I use jQuery to modify the CSS and add a background image. That way, the image isn't loaded until after page loads. Not sure about async, but this method gives the user a decent experience.
Example: http://it.highpoint.edu/
The right side navigation links have a background image. The page initializes with a background color. It is replaced with a background image after page load, via jQuery.
changes in this file jquery.ImageOverlay.js
set your height and width and enjoy this...
imageContainer.css({
width : "299px",
height : "138px",
borderColor : hrefOpts.border_color
});
As it is already mentioned, the background image is loaded asynchronously. If you need to load the background image from JQuery code you may also set the addClass() method to set a CSS class or attr("style=\"background-image:url('myimage.png')\"")
Ive found the answer myself, it was a problem due to the .offset() method that gived sometimes the wrong values.
I had the write values using the .position() :
var overlayHeaderOffset = oH.position();
