I have a web page that I want scroll automatically but the webpage is in reactjs. It has a classname called "ReactVirtualized__Grid__innerScrollContainer", I just want create a script for scroll down automatically but it doesn't work!
I will put my code:
function autoScrolling(){
var element = document.getElementsByClassName("ReactVirtualized__Grid__innerScrollContainer")[0];
element.scrollTo(0, 1000);
//window.scrollTo(0, element.scrollHeight);
}
autoScrolling();
But it only prints a number but doesn't do nothing... I tried a lot of things but nothing works...
Thanks!

I have a site that was built a few years ago, it was constructed using nested tables which is turning out to be a major issue when trying to convert the template into a responsive design.
It is an html site with a lot of SEO so the client is not willing to convert to php and risk loosing the links.
So, I decided to use the jquery load method to load the menu into a div, so if I need to add a page or change the current menu, I only have to change 1 page.
So the menu uses an older javascript code to hide the dropdowns:
var menu=function(){
var t=15,z=50,s=6,a;
function dd(n){this.n=n; this.h=[]; this.c=[]}
dd.prototype.init=function(p,c){
a=c; var w=document.getElementById(p), s=w.getElementsByTagName('ul'), l=s.length, i=0;
for(i;i<l;i++){
var h=s[i].parentNode; this.h[i]=h; this.c[i]=s[i];
h.onmouseover=new Function(this.n+'.st('+i+',true)');
h.onmouseout=new Function(this.n+'.st('+i+')');
}
}
dd.prototype.st=function(x,f){
var c=this.c[x], h=this.h[x], p=h.getElementsByTagName('a')[0];
clearInterval(c.t); c.style.overflow='hidden';
if(f){
p.className+=' '+a;
if(!c.mh){c.style.display='block'; c.style.height=''; c.mh=c.offsetHeight; c.style.height=0}
if(c.mh==c.offsetHeight){c.style.overflow='visible'}
else{c.style.zIndex=z; z++; c.t=setInterval(function(){sl(c,1)},t)}
}else{p.className=p.className.replace(a,''); c.t=setInterval(function(){sl(c,-1)},t)}
}
function sl(c,f){
var h=c.offsetHeight;
if((h<=0&&f!=1)||(h>=c.mh&&f==1)){
if(f==1){c.style.filter=''; c.style.opacity=1; c.style.overflow='visible'}
clearInterval(c.t); return
}
var d=(f==1)?Math.ceil((c.mh-h)/s):Math.ceil(h/s), o=h/c.mh;
c.style.opacity=o; c.style.filter='alpha(opacity='+(o*100)+')';
c.style.height=h+(d*f)+'px'
}
return{dd:dd}
}();
I didn't really think it would cause an issue as the css is working fine and I don't see any errors, here is how I include that html page.
<script>
$(function(){
$("#menud").load("menu.html");
});
</script>
<script type="text/javascript" src="script.js"></script>
however the dropdowns are not displaying on hover, I looked at the page in the inspector and see a lot of properties on the ul on the original page, but when inspecting the ul on the new page, it has no properties, and nothing happens when I hover over a link.
here is the link to the test page: http://pezzelectric.com/about-mobile.html
Instead of me posting 2 links, you can just remove the "/about-mobile.html" and go to the home page or any other page to see how the menu is supposed to be.
If I've understood correctly, I think you may be missing an initialisation script in your new page (/about-mobile.html).
The home page has the following near the bottom of the page:
<script type=text/javascript>
var menu=new menu.dd("menu");
menu.init("menu","menuhover");
</script>
and your new page doesn't. I tested it in my console on /about-mobile.html and it seemed to work, but I'm unsure if you couldn't use that for some reason.
I am currently writing some Javascript code that adds some tags across text in an HTML file after the page loads. I use the
window.onload
method for achieving this.
However, I am facing an issue in pages like google plus, where you get more content as you scroll down. Is there a way of calling my JS function when such a page adds more content?
Thanks

There are several ways how to get this working. You can either use jquery like this:
$('#mydiv').bind("DOMSubtreeModified",function(){
// your code goes here
alert('changed');
});
Note that this is not supported in IE8( and below).
Or you can run loop and continuously fire the desired code:
var interval = setInterval(function() {
// your code goes here
}, 1000);

I'm quite new at using jquery but learning a bit everyday. I have solved many problems searching this web but I can't seem to find any solution for this one:
The web I'm workign at the moment use quite a lot of page anchors.
I have localscroll and scrollto as jquery libraries.
I animated the transition with this little script:
<script type="text/javascript">
$(document).ready(function () {
$('.scrolllento').localScroll({ duration: 1000 });
});
</script>
and it works fine whatever I add the class "scrolllento" to the cointainer of my links.
Now the problem I have is when a link jumps to an anchor of inside different page. my client has asked me if it's possible to load the page first then move to the anchor with same web transition.
I have been working on it with my little knowdlege and this is what I have atm:
<script type="text/javascript">
$(document).ready(function () {
var nosalto = $(location).attr('href');
if (nosalto.indexOf("HistoriaBMG") > 0) {
$.fn.gotoAnchor = function (anchor) {
location.href = this.selector;
}
$('#historia').gotoAnchor();
}
});
</script>
"HistoriaBMG" is the new page and "#historia" is the anchor I want to go inside that page.
and it seems again that it works...
the problem is I have no idea how to implement now the transition as the class "scrolllento" in the container of the link going to ../HistoriaBMG is ignored.
could anyone help me? thanks so much in advance and excuse my english, hope this question is clear enough.
According to the localScroll docs:
The plugin also adds a function, $.localScroll.hash() , that checks the URL in the address bar, and if there's a hash(#an_id), it will scroll to the element. It accepts a hash of settings, just like $.localScroll. You will likely call it on document ready. Check the regular example to see it in action.
So you simply need to call $.localScroll.hash()on $(document).ready()
Background:
I'm making a portfolio site utilising both Swipe.js and Infinite Ajax Scroll (JQ).
Problem:
When the content from extra pages is loaded into the current page, it is not processed by the already-loaded Swipe.js script. This means that the new content doesn't have it's mark-up changed (needed for the swipe functionality to work).
I think I need to get the Swipe.js script to fire after each page re-load. Would that fix it? Please explain this to me like I'm an 8yr old. JS is not a strong suit...
Demo:
http://hatchcreative.co.nz/tomo
You can see that as the page loads new content, the buttons on either side of the sliders no longer work.
Yes you're right, after the images are loaded you have to create a new Swipe instance on these new elements (as they weren't there at the beginning, when the page was loaded).
Based on the docs of infinite scroll you can use onRenderComplete.
So you had your jQuery.ias constructor like this:
jQuery.ias({
// ... your settings...
onRenderComplete: function(items) {
$(items).each(function(index, element) {
new Swipe(element);
});
}
});
This should work this way somehow, but I am not exactly sure; I haven't worked with these libraries yet.
Edit:
After some more inspection of your code, I saw you had some inline click handler like: onclick='two.prev();return false;'.
You need to remove this and add your onclick handle in the same onRenderComplete function.
onRenderComplete: function(items) {
var swipe;
$(items).each(function(index, element) {
swipe = new Swipe(element);
});
// find tags with the class 'forward' inside the current element and add the handler
$(element).find('.forward').on('click', function() {
swipe.next();
});
// ... also for previous
}
By the way: Usually you should provide a jsFiddle with your important code parts, so it's easier for us to get the problem, and the question is not getting obsolote when the linked page changes.
I'm trying to bring some images from a Tumblr account and to show them using a slider. To bring the images I modified and used a script called tubmlrBadge (http://robertnyman.com/2008/09/19/tumblrbadge-a-tumblr-badge-script/), and to show the images I am using this slider > http://www.meadmiracle.com/SlidingGallery.aspx
If I check using Firebug I can see that the photos are shown okay, but I can't see them in with the slider. I can't figure out what's the problem, I suppose that a problem appears because the slider script must work with content generated by the tubmlr script. I tried placing the slider script after the tumblr one the slider still doesn't works.
You can see a demo of the this at http://www.mctest2.com.ar. If anyone has an idea please help me I tried everything!!
Thanks!
If the script you use to fetch the images was the image-fetcher itself (not a script that calls another script to get a JSON with the image data) you would have used $.getScript with a callback method.
However, your script can't use it, because no matter if the script file is loaded, it will also call another one, that might take longer to be loaded.
I think the only possibility you have is to set an "timer" in your page and wait until the gallery is loaded:
function setSlider() {
var jqelement = $('.gallery img');
if(jqelement.length>0) {
jqelement.slidingGallery();
} else {
setTimeout(setSlider, 200);
}
}
setSlider();
