I have a pdf file within iframe. I want user to scroll must in pdf file before submitting the form. i am trying with this,
var position = $('#myIframe').contents().scrollTop();
But not working. Please help me Thanks in advance.
If you don't mind making a static height for your iframe, I have a solution for you.
HTML and CSS
1. Wrap your iframe in a div container
2. set heights for both your container and iframe (height of container should be the height you want your frame to be seen and the iframe height should be large enough to show entire pdf.)
3. set container div's overflow to scroll
Now you have a scrollable "iframe".
Javscript
Get container element. (var containerEl = $("#container")[0];)
Write a scroll function. Within the scroll function find if the total height of the element (scrollHeight) is less than or equal to how much has been scrolled (scrollTop) plus the inner height (clientHeight) of the
element. If it is, remove disabled property from button
Here's the fiddle. Made some changes to #mJunaidSalaat's jsfiddle.
Well I've tried almost an hour on this, Researched it, finally coming to a conclusion that Unfortunately this is not possible using this method.
The PDF is usually not a DOM element, it's rendered by PDF reader software. Every browser has its own mechanism for rendering PDFs, there is no standard. In some cases, the PDF might be rendered by PDF.js; in those situations you might be able to detect scrolling. But Adobe Reader, Foxit, and some of the native PDF rendering don't provide that option.
I've also created a Github issue for this. But no use.
Sorry. Please update me if you could find any thing or any workaround.
I've made a Fiddle for your solution. You can disable the submit button for user until user scroll on your iframe.
function getFrameTargetElement(objI) {
var objFrame = objI.contentWindow;
if (window.pageYOffset == undefined) {
objFrame = (objFrame.document.documentElement) ? objFrame.document.documentElement : objFrame = document.body;
}
return objFrame;
}
$("#myIframe").ready(function() {
var frame = getFrameTargetElement(document.getElementById("myIframe"));
frame.onscroll = function(e) {
$('.submitBtn').prop('disabled', false);
}
});
Hope it helps.
try this
$("#myIframe").ready(function() {
var frame = getFrameTargetElement(document.getElementById("myIframe"));
frame.onscroll = function(e) {
$('.submitBtn').prop('disabled', false);
}
});

I have created a script that adds the scrollTop value to the height of a DIV
var scroll = $(this).scrollTop();
console.log(scroll);
function scrollH() {
document.getElementById("overlay").style.height = scroll + 'px';
}
document.getElementById("overlay").addEventListener("scroll", scrollH());
I need this style to keep updating (I'm making a progress bar). Currently it only changes when I refresh the page.
Thanks in advance
(Sorry if I did not follow the correct question format for this site, this is my first question :L )
You want to apply styles via JavaScript after the DOM has loaded.
JQuery helps with this:
$(document).ready(function() {
//do something to css
});
https://learn.jquery.com/using-jquery-core/document-ready/
You could apply a listener to whatever event is triggering an update, and then replace or fill the progressbar with it's new value.
I've spent quite a while trying to find answers for this issue, but haven't had any success. Basically I need to scroll the user to the contact portion of the website when they go to healthdollars.com/#contact. This works just fine in Safari, but in Chrome I haven't had any luck. I've tried using jQuery/Javascript to force the browser to scroll down, but I haven't been able to.
Does anyone have any ideas? It's driving me crazy - especially since it's such a simple thing to do.
Not a full answer but in Chrome if you disable Javascript I believe you get the desired behavior. This makes me believe that something in your JavaScript is preventing default browser behavior.
It looks to me like the target element doesn't exist when when page first loads. I don't have any problem if I navigate to the page and then add the hash.
if (window.location.hash.length && $(location.hash)) {
window.scrollTo(0, $(location.hash).offset().top)
}
check for a hash, find the element's page offset, and scroll there (x, y).
edit: I noticed that, in fact, the page starts at #contact, then scrolls back to the top. I agree with the other answerer that there's something on your page that's scrolling you to the top. I'd search for that before adding a hack.
You can do this with JS, for example` if you have JQuery.
$(function(){
// get the selector to scroll (#contact)
var $to = $(window.location.hash);
// jquery animate
$('html'/* or body */).animate({ scrollTop: $to.offset().top });
});
The name attribute doesn't exists in HTML 5 so chrome looks to have made the name attribute obsolete when you use the DOCTYPE html.
The other browsers have yet to catch up.
Change
<a name="contact"></a>
to
<a id="contact"></a>
Maybe this workaround with vanilla javascript can be useful:
// Get the HTMLElement that you want to scroll to.
var element = document.querySelector('#contact');
// Stories the height of element in the page.
var elementHeight = element.scrollHeight;
// Get the HTMLElement that will fire the scroll on{event}.
var trigger = document.querySelector('[href="#contact"]');
trigger.addEventListener('click', function (event) {
// Hide the hash from URL.
event.preventDefault();
// Call the scrollTo(width, height) method of window, for example.
window.scrollTo(0, elementHeight);
})
I needed to be able to load a particular page in an iframe on demand, so I used a simple wrapper:
function updateFrame(url) {
frames[0].location = url;
}
Then I was asked to load the page to a particular point, which was non-trivial, since the pages were not within my control and there weren't always <a name> anchors to rely on. So some poking around showed that IDs could be used as anchors.
That is to say, you can scroll to <div id = "somewhere-down-the-line"> with:
updateFrame("http://host/page#somewhere-down-the-line");
except this call also scrolls the entire viewport up so that the above <div> goes to the top and everything in the parent page above it scrolls out of view.
How do I modify updateFrame(url) so that it scrolls the page within the <iframe> but leaves the rest of the page as it is?
This hack worked for me on Firefox 20.0.1/Windows. Essentially, I load the page first, then jump to the target:
function updateFrame(url) {
if (url.indexOf('#') > -1) {
mainPage = url.split('#')[0];
frames[0].location = mainPage;
}
frames[0].location = url;
}
I would like to be able to use this in other browsers as well. I have been trying to get it to work in Chrome. Maybe I'll even try Internet Explorer...
If a hack is ok, and what you're looking for is cross-browser try using scrollTop to reset where you were.
E.g. if it is the body that scrolls
function updateFrame(url) {
//save where you were
var oldScroll = document.body.scrollTop;
//this moves our body!
frames[0].location = url;
//move it back
document.body.scrollTop = oldScroll;
}
Of course if it doesn't actually scrolls the entire viewport and instead modifies a parent div or something, the scrollTop property will be on that element too.
Let me know if this works, but screws up the scrolling on the frame, because I can modify this to account for a difference between the two scrollTops
You could try turning the bolts yourself by detecting the height of the element you want, and forcing the scrollTop of the frame.
function updateFrame(url) {
//get the parts
var parts = url.split('#');
//go to the url
frames[0].location = parts[0];
//if there was an anchor
var anchor;
if (parts.length > 0 && parts[1].length > 0) {
//may want to account for a[name="PARTS[1]"] too
anchor = frames[0].document.getElementById(parts[1]);
//set the scroll of it yourself, using some sort of library to get "fullTop"
frames[0].document.body.scrollTop = anchor.fullTop();
}
}
Where "fullTop" is equivalent to the distance between the top of the iframe, and the element.
Like jQuery's .offset() or YUI's getXY(el).[1]
What worked for me on Firefox 20.0.1/Windows. Essentially, I load the page first, then jump to the target:
function updateFrame(url) {
if (url.indexOf('#') > -1) {
mainPage = url.split('#')[0];
frames[0].location = mainPage;
}
frames[0].location = url;
}
On Chrome 28.0/Windows, calling updateFrame(url) followed by setting document.body.scrollTop = 0 (thanks to this answer) had the desired effect, though only in the console. I am still testing on other browsers; a more elegant solution is always appreciated :)
As mentioned in the question, though, I would like to be able to use this in other browsers as well. Maybe I'll even try Internet Explorer...
I have a modal dialog (window.showModalDialog) with html in it. when I resize the dialog, the HTML within it does not repect the new boundaries and I get scroll bars or elements that don't expand 100% to the new width.
To fix this I have to drag it around for a bit and it then jolts it self back into the correct sizes.
To fix it programtically. I do the following window.document.getElementById('removeMainBody').innerHTML =window.document.getElementById('removeMainBody').innerHTML;
But this causes some dynamic objects in the html to stop functionin.
How can i solve this problem and make the elemnts within the dialog resize after I resize the dialog?
Here is my code
else if(<c:out value="${staffCount}" /> > 1){
document.getElementById('removeDiv').style.display = '';
window.dialogWidth='770px';
window.dialogHeight='320px';
window.document.getElementById('removeMainBody').innerHTML =window.document.getElementById('removeMainBody').innerHTML;
}
If you set a style or a Class from the Body-Tag, this should force an HTML Reflow, and the Site would be displayed correct again, without setting the innerHTML Property.
example:
...
window.document.body.className = "relfow";
// if the body class Attribute was set, than set it now back
window.document.body.className = "oldBodyStyleClassName" ; / Or just to ""
...
if the browser optimizes, the refresh calls, so that now reflow occures you could
setTimeout(function(){
...
window.document.body.className = "relfow";
// if the body class Attribute was set, than set it now back
window.document.body.className = "oldBodyStyleClassName" ; / Or just to ""
...
})
i hope this helps. (here you can find some info to Reflow Link)
A new "google related" bar shows up at the bottom of my website. It displays links to my competitors and other things like maps, etc. It is tied in with users using the google toolbar. If anyone has any ideas on how I can disable from displaying on my web side I would sure appreciate it.
Taken from http://harrybailey.com/2011/08/hide-google-related-bar-on-your-website-with-css/
Google inserts an iframe into your html with the class .grelated-iframe
So hiding it is as simple as including the following css:
iframe.grelated-iframe {
display: none;
}
Google removed div and frame names and put everything to important so original answer no longer works on my site. We need to wait for the iframe to be created and then hide it by classname. Couldn't get .delay to work, but this does...today anyway.
$(document).ready(function() {
setTimeout(function(){
$(‘.notranslate’).hide();},1000);
});
Following javascript code tries to find the google related iframe as soon as the window finishes loading. If found, it is made hidden, else an interval of one second is initialized, which checks for the specified iframe and makes it hidden as soon as it is found on page.
$(window).load(function (){
var giframe = null;
var giframecnt = 0;
var giframetmr = -1;
giframe = $("body > iframe.notranslate")[0];
if(giframe != null)
$(giframe).css("display", "none");
else
giframetmr = setInterval(function(){
giframe = $("body > iframe.notranslate")[0];
if(giframe != null) {
clearInterval(giframetmr);
$(giframe).css("display", "none");
} else if(giframecnt >= 20)
clearInterval(giframetmr);
else
giframecnt++;
}, 1000);});
Find the parent DIV element that contains the stuff in the bar. If it has an id or name attribute, and you can control the page CSS then simply add a rule for the element, i.e. if you see something like
<div id="footer-bar-div".....
then add a CSS rule
#footer-bar-div {display:none ! important}
This will not work if the bar is inside an iframe element, but even in that case you should be able to hide it using javascript, but you will need to find the name/id of the frame, i.e.:
var badFrame = document.getElementById('badFrameId').contentWindow;
badFrame.getElementById('footer-bar-div').style.display='none';
if the frame has a name, then instead you should access it with:
var badFrame = window.frames['badFrameName']
There is also a chance that the bar is generated on-the-fly using javascript. If it is added to the end of the page you can simply add a <noscript> tag at the end of your content - this will prevent the javascript from executing. This is an old trick so it might not always work.
