Im looking for my webpage to jump to an iframe when someone click. I've found one solution which works pretty well which is this: http://jsfiddle.net/RGjCL/4/
<ul>
<li>
Class Name
</li>
</ul>
<script type="text/javascript">
function IFrameScroll(link){
window.myIframe.location=link;
window.location.hash='myIframe'
}
</script>
<IFRAME id = "myframe" onload = "setIframeHeight( this.id )" name="myIframe">
I've tried on my web and it partially works except for the fact it scrolls to the iframe before it loads so it doesn't goes that far to the bottom because once the iframe its loaded the page fully extends.
The web in question is the following: http://www.clavederock.com.ar -
The links are under the tabs "Quienes Somos" "Programacion" and "Archivo".
I hope i made myself clear so you can help me. Thanks in advance!
Try moving window.location.hash='myIframe' from the function IFrameScroll() to setIFrameHeight(), so you'll change the hash once the iframe have the desired size.
EDIT #3:
Since you need to wait until iframe is loaded in order to resize it and window.location.hash doesn't works the second time in chrome, you can try this:
<script type="text/javascript">
function IFrameScroll(link){
window.myIframe.onload = function() {
// this will ensure that the height will be updated after load
setIframeHeight('myIframe');
// This works on FF and IE, and let users to bookmark
window.location.hash='myIframe';
// and this will allow it to scroll the second time for chrome
document.getElementById('myIframe').scrollIntoView(true);
}
window.myIframe.location=link;
}
</script>
I really hope this solve your problem :)
Instead of jumping to the iframe, you could make a smooth scroll. This would give a little more time for the iframe to load after the link has been clicked.
Alternatively and probably more effectively, you could load the iframe with the rest of the page but make it invisible. Then you just need to show it when the user clicks the link
//load the page with the iframe hidden
//in css
#myIframe { visibility: hidden; }
//use jquery to make it visible when the user clicks the link
//you could do this with javascript if you don't want to import jQuery, but I find jQuery easier
$(document).ready(function() {
$('#myAnchorTagId').click(
function() {
$('myIframe').css('visibiliy', 'visible')
}
)
});

I recently published a website with a simple SVG animation of a Panda on a rocket. As soon as the user scrolls down, the image changes to another SVG with an animation of the panda going up and away from the screen.
The website: https://www.jonnyekholm.fi
I'm using this simple script to make it happen:
<div style="left:10%;" id="rocket" >
<img width="30%" height="auto" src="https://www.aaltowave.com/img/RocketPanda.svg" />
</div>
<script>
jQuery(window).scroll(function() {
jQuery( "img[src='https://www.aaltowave.com/img/RocketPanda.svg']" ).attr("src","https://www.aaltowave.com/img/RocketPanda2.svg");
});
</script>
This works fine on Chrome.
This also works on Firefox, at first. But if you reload the page and scroll down again then the panda just disappears. Same thing happens in Safari.
Im also using this script on the same page, to make the panda move across the screen at a later point:
<div id="trigger"></div>
<img src="https://www.aaltowave.com/img/still2.svg"/>
<script>
jQuery(function() {
var $window = jQuery(window);
var endpoint = jQuery("#trigger").offset().top - $window.height();
$window.on('scroll', function() {
if ( (endpoint) < $window.scrollTop() ) {
jQuery( "img[src='https://www.aaltowave.com/img/still2.svg']" ).attr("src","https://www.aaltowave.com/img/movement22.svg");} });});</script>
This works fine on Chrome.
On Safari this doesn't execute on reload, just like with the previous animation.
On Firefox however, the animation doesn't occur at all except for one or two occasions. This tells me that the script does in fact work on firefox, but it executes on a weirdly basis.
How can I make the panda animations show up on Firefox?
I would appreciate it very much if anybody could help me with solving this problem. Thank you in advance!
Based upon happymacarts suggestions, this is most likely a cache issue. On reload the animation is loaded, but at the last frame where it is already off the screen. One must force an image reload for this to succeed.
To be able to reload the image and bypass the caching I added a unique query parameter to the URL and put the scripts together:
jQuery(window).scroll(function() {
jQuery( "img[src='https://www.aaltowave.com/img/RocketPanda.svg']" ).attr("src","https://www.aaltowave.com/img/RocketPanda2.svg?t=" + new Date().getTime());
jQuery( "img[src='https://www.aaltowave.com/img/still2.svg']" ).attr("src","https://www.aaltowave.com/img/movement22.svg?t=" + new Date().getTime());
});
Chrome: Works like charm
Safari: Works like charm
Firefox: This solves the issue for the first animation, but the second one only shows up if the user has scrolled down to the location and then reloads the page. Not in any other occasion. Still working on a solution for the second animation...
i have a WordPress site and problems with anchors. i have a page with several anchors which are linked to in the main menu. when i am on the page itself, all anchors work fine, but if I'am on any other page, they don't work, at least not in all browsers and the anchors are ignored.
As being informed it is a chrome bug, ive found this solution:
<script type="text/javascript">
jQuery(window).load(function(){
var hashNum = 0;
if (window.location.hash != ''){
hashNum = window.location.hash.replace("#oneofmanyanchors", "");
console.log('hashNum: ' + hashNum);
};
hashMenu = jQuery('[data-q_id="#oneofmanyanchors"]').offset().top;
jQuery('html,body').animate({
scrollTop: hashMenu
}, 0);
});
</script>
above code is working and fixes the issues i had in chrome and ff.
however i need this added functionality: At the moment it is addressing only one specific anchor, but i need it to work with any anchors in the page url, not just the one above (anchors are referenced with the data-q_id attribute).
so the code needs to be updated that it grabs any given anchor from the page URL and go to / scroll to that anchor (once) via jquery after first page load.
How do i achieve this?
Thanks in advance!
PS: The problem is caused by theme incompatibility with a certain plugin i need...
I think this should work in every browser - what happens to be the problem?
In order to achieve this in jquery you should scroll to the element/anchor with javascript as soon as the document is loaded.
So like this:
$(function() {
location.hash = "#" + hash;
});
I still think you should find out what went wrong and why the linken from another page doesn't work in some browser before using a workaround for the problem. Your code will just ged more and more messy like that.
How to scroll HTML page to given anchor using jQuery or Javascript?
and here
$(document).ready shorthand
I need to scroll down about 50px when the page is loaded. This is what I'm using:
$(window).load(function(){
$("html,body").scrollTop(55);
});
I've also tried:
scrollTo(0,55)
This works fine in Firefox and IE, however in Chrome, Safari and Opera it scrolls down to the proper position and then jumps back up to the top(or the last scroll position).
I've also tried using an element id to scroll down, but the browser still overwrites it. I tried like this:
htttp://website.com#element
I think your problem is that you are using $(window).load and some browsers are having problem as things havnt fully rendered yet. Try swapping to
$(document).ready(function(){
$("html,body").scrollTop(55);
});
Seems to work fine in all browsers here http://jsfiddle.net/7jwRk/1/
Info
$(document).ready
executes when HTML-Document is loaded and DOM is ready
$(window).load
executes when complete page is fully loaded, including all frames, objects and images
<script type="text/javascript">
$(document).ready(function(){
var divLoc = $('#123').offset();
$('html, body').animate({scrollTop: divLoc.top}, "slow");
});
</script>
Add id="123" to any <div> it will automatically scroll it down when page loads.
Here's an another script if the previous one wont work !
<script>
window.setInterval(function() {
var elem = document.getElementById('fixed');
elem.scrollTop = elem.scrollHeight; }, 3000);
</script>
Add id="fixed" to any <div> it will automatically scroll it down when page loads.
You can use the scrollIntoView() function. This is supported accross most browsers (even IE6).
document.getElementById('header').scrollIntoView()
After messing with scrollIntoView(), and observing it scroll correctly at page paint time, then snap to the top for no reason, I went with this:
http://website.com/#target
and
<a name="target">
Then the browser understands exactly what I need and does it. But I can only do this because we control the URI, so it naturally also won't work in all situations.
Alternatively, just fire this at the end of your body:
...
<script type="text/javascript">
$("html,body").scrollTop(55);
</script>
</body>
</html>
If you are using 2 monitors, be sure that when you open the window of your browser with the page for which the script is implemented, you don't move that window to the other monitor, with a different screen resolution. Shortly: don't cross the windows of the browser to a different monitor, just open a new window of the browser for each monitor/ screen resolution.

I want to use iScroll in iframe.
This is my code
HTML
<form>
<input type="text" class="frmUrlVal">
<input type="submit" class="frmSubmit" value="Go">
</form>
<iframe src="http://www.css-tricks.com" width="360" height="500" id="dynFrame"></iframe>
JS
$(function()
{
$('.frmSubmit').click(function(e)
{
$('#dynFrame').attr('src', $('.frmUrlVal').attr('value'));
e.preventDefault();
});
});
This is my jsfiddle link : http://jsfiddle.net/ajaypatel_aj/JtCJa/
You can see here there is vertical scrollbar, i want to use iSroll instead of that regular scroller.
I tried with applying the id but it not work for me.
Thanks In Advance !
I think the closest option you would have is http://jsfiddle.net/JtCJa/9/ it will still need tweaking and you cannot click the links but it works as you would expect :)
You can't do this from parent frame. You must add iScroll's script directly to "http://www.css-tricks.com" page. If this site doesn't belong to you, you can't do this because executing JavaScript code on pages from different domain is forbidden for security reasons.
You can set very big height of frame, so scroll bar inside the frame will disappear, only the scroll bar of parent frame will remain. This scrollbar can be styled with JavaScript because it belongs to your domain. But I think scrolling page with mouse inside frame will not work (you can't receive mouse events from third-party frame). And page height becomes very big (you can't determine the height of frame contents).
Well, you can download entire page contents on server side and display its copy on your site. In this case JavaScript on this page will work and scrollbar can be styled. There are several scripts for doing this. Trey're called "web proxies". You can use one of them, for example, PHProxy. It's complicated to implement this functionality yourself because there are some techinal difficulties (downloading related files, redirecting ajax requests, saving cookies etc).
hey ajajy you have to add class also in your file
<iframe src="http://www.css-tricks.com" width="360" height="500" id="navbar" class="navbar_relative"></iframe>
and js funcation
function magentoScrollMimic(){
j(document).scroll(function(e){
if(j(window).scrollTop()>138)
{
j('#dynFrame').addClass('navbar_fixed');
j('#dynFrame').removeClass('navbar_relative');
}
else
{
j('#dynFrame').removeClass('navbar_fixed');
j('#dynFrame').addClass('navbar_relative');
}
});
}
samjyo
and use directly
<ul id="dynFrame" class="navbar_relative">
i used this and its working
j(document).ready(function(){
magentoScrollMimic(); }
I have some JavaScript that can appear on many different pages. Sometimes those pages have been accessed via a URL containing an anchor reference (#comment-100, for instance). In those cases I want the JavaScript to delay executing until after the window has jumped. Right now I'm just using a delay but that's pretty hackish and obviously doesn't work in all cases. I can't seem to find any sort of DOM event that corresponds to the window "jump".
Aside from the simple delay, the only solution I've come up with is to have the JS look for the anchor in the URL and, if it finds one, watch for changes in scrollTop. But that seems buggy, and I'm not 100% sure that my script will always get fired before the scrolling happens so then it would only run if the user manually scrolled the page. Anyhow, I don't really like the solution and would prefer something more event driven. Any suggestions?
Edit to clarify:
I'm not trying to detect a hash change. Take the following example:
Page index.php contains a link to post.php#comment-1
User clicks the link to post.php#comment-1
post.php#comment-1 loads
$(document).ready fires
Not long later the browser scrolls down to #comment-1
I'm trying to reliably detect when step 5 happens.
You can check window.onhashchange in modern browsers. If you want cross compatible, check out http://benalman.com/projects/jquery-hashchange-plugin/
This page has more info on window.onhashchange as well.
EDIT: You basically replace all anchor names with a similar linking convention, and then use .scrollTo to handle the scrolling:
$(document).ready(function () {
// replace # with #_ in all links containing #
$('a[href*=#]').each(function () {
$(this).attr('href', $(this).attr('href').replace('#', '#_'));
});
// scrollTo if #_ found
hashname = window.location.hash.replace('#_', '');
// find element to scroll to (<a name=""> or anything with particular id)
elem = $('a[name="' + hashname + '"],#' + hashname);
if(elem) {
$(document).scrollTo(elem, 800,{onAfter:function(){
//put after scroll code here }});
}
});
See jQuery: Scroll to anchor when calling URL, replace browsers behaviour for more info.
Seems like you could use window.onscroll. I tested this code just now:
<a name="end" />
<script type="text/javascript">
window.onscroll = function (e) {
alert("scrolled");
}
</script>
which seems to work.
Edit: Hm, it doesn't work in IE8. It works in both Firefox and Chrome though.
Edit: jQuery has a .scroll() handler, but it fires before scrolling on IE and doesn't seem to work for Chrome or Firefox.
To detect when the element appears on the screen, use the appear plugin:
$('#comment-1').appear(function() {
$(this).text('scrolled');
});
