Is there a way that I can change my parallax image when an event is fired? I am using parallax.js and I cannot seem to figure out a way.
Here's the HTML:
<div class="bg-page-index">
img_link_1
</div>
<div class="bg-page-index">
img_link_2
</div>
<div class="bg-page-index">
img_link_3
</div>
<div id="hero">
<div class="product-color-list">
<div class="color"></div>
<div class="color"></div>
<div class="color"></div>
</div>
</div>
JS:
$(".color").click(function() {
var indexNum = $(".product-color-list .color").index(this);
sliderInit(indexNum);
});
var $hero = $("#hero"),
$bg_index = $(".bg-page-index"),
bg_init = $bg_index.eq(indexNum).html();
$hero.parallax({
imageSrc: bg_init,
speed: 0.7
});
This works the first time, but it won't work a second time because the parallax.js library changes things around with the element. Does anyone know a better way of doing this, or how to reinitiate the library?
I found a solution that works. Rather than re-initiate the plugin every time I want to change the background I simply changed the image src within the element this plugin creates:
$('.parallax-slider').attr('src', background);

I've been writing a mini image editor. Upon uploading the to-be-edited image, I draw it into a canvas. One of the editing tools is to add a picture frame, which is taken from several sample images
This is the relating part of my HTML code
<div id="canvas-frame">
<canvas id="edit-canvas" width="500"></canvas>
</div>
<div id="border-tool" class="tab-pane fade">
<div class="border-selection active">
<img src="img/hien/no-border.jpg" id="no-border">
</div>
<div class="border-selection">
<img src="img/hien/border1.png">
</div>
<div class="border-selection">
<img src="img/hien/border2.png">
</div>
</div>
And this is the JavaScript code implementing it
$('#canvas-frame').width($('#edit-canvas').width());
$('#canvas-frame').height($('#edit-canvas').height());
function placeBorder(src){
$('#canvas-frame').css('border-image','url('+src+') 30 round');
$('#canvas-frame').css('border-width','20px');
}
$('#border-tool .border-selection img').click(function(){
$('#border-tool .border-selection.active').removeClass('active');
$(this).parent().addClass('active');
if ($(this).attr('id')=='no-border'){
$('#canvas-frame').css('border','none');
} else{
placeBorder(this.src);
}
});
As you can see, my idea is to use the canvas-frame div to wrap around the canvas, then try changing css of it. But now I encounter another problem, how to implement a Save button to download the canvas with the bordering frame around it. Could you please give me any suggestions or tutorials to do it? Thanks a lot
I'm trying to implement this signaturePad https://github.com/szimek/signature_pad, and when I tried in a single page it works fine, but the problem comes when I try to put inside a div, which is hidden at the begining, then the pad doesn't work. I think is a canvas problem with the resizing, but I don't know how to solve it.
This is my code:
<div class="col-sm-9 col-md-10 message-list">
This is the first div, which I hidde when click on a row
</div>
<div class="col-sm-9 col-md-10 view-message" style="display:none" >
<div id="signature-pad" class="m-signature-pad">
<div class="m-signature-pad--body">
<canvas></canvas>
</div>
<div class="m-signature-pad--footer">
<div class="description">Sign above</div>
<button type="button" class="button clear sign_btn" data-action="clear">Clear</button>
<button type="button" class="button save sign_btn" data-action="save">Save</button>
</div>
</div>
and this is the js part:
$(document).ready(function() {
$(".list-group-item").each(function() {
$(this).click(function() {
$(".message-list").fadeOut('slow').css('display','none');
$(".view-message").fadeIn('slow').css('display','block');
});
});
I loaded all the js and css required and it is working in the main view, but not when I go through a button and change the div to block. I tried to read the documentation, but is not very clear.
Use: height: 0; overflow: hidden;
instead of: display:none
It works for me.
Can you try setting visiblity hidden instead of display:none ?
$(".list-group-item").each(function() {
$(this).click(function() {
$(".message-list").fadeOut('slow').css('visibility','hidden');
$(".view-message").fadeIn('slow').css('visibility','visible');
});
});
CSS manipulations didn't work for me. Instead of playing with CSS, I didn't render the signature pad until the user was ready to sign. I.e. wrap the signature pad component with the condition that listens to some event.
I've created a website called "Pumpn Records" and it's almost finished. On the website there is a section called "Releases". It is divided in two sections, but only one is visible.
So this is the website: http://s448350928.online.de/pumpn/records/index3
The Releases Section there has this html code (simplified):
<div class="container1" id="releases">
<script src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"> </script>
<script>
function hide2014and2016show2015()
{
$("#2014").fadeOut(4000);
}
</script>
<script>
$(document).ready(function(){
$("#2015").hide();// hide it initially
$('#forward2014').click(function(){
$("#2015").delay(4000).fadeIn(4000); });
});
</script>
<h2>Releases</h2>
<div id="yearcontainer">
<div id="back2014" style="display:inline-block">
<img id="back2014img" src="..."/>
</div>
<h2 id="year">2014</h2>
<div id="forward2014" onclick="hide2014and2016show2015();" style="display:inline-block">
<img id="forward2014img" src="..."/>
</div>
</div>
<div id="2014">
<div class='container3' style="overflow:visible;">
<h2>EPs</h2>
<div class='row2'>
<a href="...">
<img width="300px" src="..."/>
<h2>Nano Miratus</h2>
<h3>Ganz Okay EP (Instrumental)</h3>
</a>
</div>
<div class='row2'>
<a href="...">
<img width="300px" src="..."/>
<h2>Nano Miratus</h2>
<h3>Ganz Okay EP</h3>
</a>
</div>
<div class='row2'>
<a href="...">
<img width="300px" src="..."/>
<h2>Nano Miratus</h2>
<h3>Viernacheins EP</h3>
</a>
</div>
</div>
</div>
<div id="2015">
<div class='container3' style="overflow:visible;">
<h2>Alben</h2>
<div class='row2'>
<a href="...">
<img width="300px" src="..."/>
<h2>Nano Miratus</h2>
<h3>Larmoyanz</h3>
</a>
</div>
</div>
<div class='container3' style="overflow:visible;">
<h2>EPs</h2>
<div class='row2'>
<a href="...">
<img width="300px" src="..."/>
<h2>Nano Miratus</h2>
<h3>Mrs. EP</h3>
</a>
</div>
</div>
</div>
</div>
If you look at the Releases Section, you will see there is this title ("2014"). Left and right to this titles are arrows, or carets I think they are called. :D
What I wanted to code is:
When someone clicks on the right arrow, the div with the id "2014" should fade out in 4000 milliseconds, then the div with the id "2015" should fade in in 4000 milliseconds. I put a delay before the fade in of that "2015" div. It's also 4000 milliseconds, so the fade in of "2015" should start right after the fade out of "2014" has finished.
What really happens is: http://i.stack.imgur.com/hxLVB.gif
So why isn't it working? I googled and stackoverflowed so much in the last hours and changed that code so often, but it still doesn't work. :(
UPDATE:
Now I know what the problem is, but I can't solve it. This website is a single page website, so I have a javascript plugin. It's called fullpage.js and I know how it works. When you scroll with your mouse, it adds an "transform: translate3d(x, y, z);" property to the "page-container fullpage-wrapper", and changes the y-value, so the page goes down. So I made two fiddles for a demonstration of the problem:
NOT WORKING FIDDLE (with the transform property in it):
jsfiddle.net/ktf9onjo/ (sorry, I'm not allowed to post more then two clickable links...)
WORKING FIDDLE:
jsfiddle.net/rant5af9/
You see that the problem is the transform property.
WHY???
I need an alternative. I cannot just remove it, the script will
be readd it every time I scroll.
Yeah, I could just change the translate3d(x, y, z) to a translateY(y), but nooo, that isn't working, I tried it. :D
INFO: You can find the fullpage.js in the javascript box in both fiddles.
PS: The website isn't finished yet. A lot of links and other things aren't working at the moment.
Please help, fanx! :)
Why the problem happens
As explained by #kosmos in comment:
Because the queue for animations is for every element animation itself. a won't wait for b to make its animation, but if you try to animate a two times, the second animation will wait for the end of the first one.
Solution
jQuery fadeOut function accepts a complete callback function (source).
This callback function is executed once the fade-out is complete. You don't need to use delay anymore this way, and your animations chaining will keep in sync.
html:
<div id="forward2014" style="display:inline-block">
javascript:
$('#forward2014').click(function(){
$("#2014").fadeOut(4000, function(){
// this starts when the fadeOut is finished
$("#2015").fadeIn(4000);
})
});
demo in this snippet
(click the >> as forward button)
$(document).ready(function(){
$("#2015").hide();
$('#forward2014').click(function(){
$("#2014").fadeOut(4000, function(){
// this starts when the fadeOut is finished
$("#2015").fadeIn(4000);
})
});
});
<div id="2014"style="display:inline-block">
2014
</div>
<div id="2015"style="display:inline-block">
2015
</div>
<div id="forward2014">
>>
</div>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
Further remarks:
You may want to use jQuery's .on function for event listeners (reference). You can replace the onclick= and the .click by it. This should make your code easier to manage and more performant.
The ids in your html are supposed to contain at least a letter (source). Replace id="2014" by id="year-2014" or something like that.
i didn't got what you need exactly but to make to jquery actions going sequences you must call the second action with call back like this
$('#whatever').fadeOut('slow', function() {
$('#whatever').delay(4000).fadeIn('slow');
});
See This
I have this JS code:
function overlay() {
el = document.getElementById("overlay");
el.style.visibility = (el.style.visibility == "visible") ? "hidden" : "visible";
}
which opens up a new window on click. What I want it to do next from that first click is go to another function. That function entails a scroller that has 5 divs in it. Say I want it to go to the third div or ID, how would I go about writing that type of function? So a HTML example would be:
<div id="this">
<div class="outer">
<div class="innerdiv">
<div class="1" id="1">1</div>
<div class="2" id="2">2</div>
<div class="3" id="3">3</div>
<div class="4" id="4">4</div>
<div class="5" id="5">5</div>
</div>
</div>
</div>
This would represent my scroller. So on that initial first click, the idea is that it would open up a new window and scroll to that 3rd div, or if scrolling to it is to difficult, then go to that first div. http://jsfiddle.net/qYTK4/
<div class="arrowbox">
<div style="display:inline-block; width:155px; height: 50px; float:left;"></div>
<div class="leftbox" id="leftbox"></div>
<div class="backtohome">BACK TO HOME PAGE</div>
<div class="rightbox" id="rightbox"></div>
Using window.scrollTo() and move it to the objects position. Retrieve the position (X,Y) of an HTML element
jQuery.ScrollTo is a great, simple plugin for smooth scrolling animations. It has tons of options for ways to define the scroll behavior and is pretty easy to use. There are a ton of demos and examples on the site linked you should be able to use. In yours you would just tell it to scroll to either the DOM element itself or jQuery object/selector for the 3rd div.
Also, you can't have id attributes start with numbers (like your divs), it's not valid. Classes can but not IDs.
It is also a good idea to rely on click event handlers (i.e. $('.backtohome a').on('click', function() { // your code });) rather than onclick attributes.
So let's say have the following content structure:
<div class="wrapper">
<div class="contentOne" style="width:50px"></div>
<div class="contentTwo"></div>
<div class="contentThree"></div>
<div class="contentFour"></div>
</div>
What I want to achieve on page load, is for the width of the 1st div (contentOne) to be picked up and increment the width of the other 3 divs by 50px. In the end I want the following:
<div class="wrapper">
<div class="contentOne" style="width:50px"></div>
<div class="contentTwo" style="width:100px"></div>
<div class="contentThree" style="width:150px"></div>
<div class="contentFour" style="width:200px"></div>
</div>
First prize would be for this to be possibly using CSS3 Calc. If not JS will be a close 1st princess.
Thanks
Right now, CSS has no preceding-sibling selector (although there is a "following sibling" selector, for some reason), so a pure CSS solution isn't yet possible. jQuery would be something like this:
$('div:not(:first)').each(function()
{
$(this).width($(this).prev().width() + 50);
});
Use Jquery to this . The code would be something like this. Please make the changes appropriate this is just a demo code.
var widthOfFirstChild=$('.wrapper').eq(1).width();
$('.width div').each(
function(){
$(this).attr('style':widthOfFirstChild+50);
widthOfFirstChild=+50
});
