I'm using Drupal 7 and get my content with View module on page. And my pager Views Load More module. And my thumbnail effect hover, shadow etc. Image hover using this code:
var hoverImg = '<div class="hoverimg"></div>';
$(".thumb").each(function(){
$(this).children("div").each(function(){
$(this).find("a").append(hoverImg);
});
});
$(".thumb div").hover(function() {
$(this).find(".hoverimg").animate({ opacity: 'toggle' });
});
$(".thumb").hover(function() {
$(this).find("div").each(function(){
$(this).find(".shadow").fadeOut(500);
});
});
And getting number on my current thumbnail. This code:
var c = '';
var d = '';
$('.view-content div.views-row').each(function(){
c = 0;
d = 0;
var i = 1;
d = $(this).find('.thumbimg').length;
$(this).find('.thumbimg').each(function(){
sayi=i++;
$(this).append('<div class="img_no">0'+sayi+'</div>');
});
});
Everything is OK. All effects on start page. But when click Load More button, my effects can't work another page.
How do i solve this problem? Thanks.
The reason why it stops working is due to the hover function (and your other scripts/functions) only works on existing elements. So if you add something with ajax, it wont apply to that unless you reload the script after the ajax load.
Another option is to use live() or on() (for the hover part. On is the new version of live, added in jQuery 1.7).
Live and on listens for any existing or future elements.
A live script would look something like this:
$(".yourElement").live({
mouseenter:
function () {
// Do something
},
mouseleave:
function () {
// Do something
},
mousemove:
function () {
// Do something
}
});

I need some help making a sub-menu appear within 2s after the page loads instead of when the user clicks on it. I'm using JQuery. That file is the core of the website. I need it to stay opened.
Here's the code I have at the moment, I tried to change that on.Click event but it didn't work.
The handleSidenarAndContentHeight(); function resizes the menu items after the sub-menu appears.
jQuery('.page-sidebar li > a').on('click', function (e) {
if ($(this).next().hasClass('sub-menu') === false) {
return;
}
var parent = $(this).parent().parent();
parent.children('li.open').children('a').children('.arrow').removeClass('open');
parent.children('li.open').children('a').children('.arrow').removeClass('active');
parent.children('li.open').children('.sub-menu').slideUp(350);
parent.children('li').removeClass('open');
parent.children('li').removeClass('active');
var sub = jQuery(this).next();
if (sub.is(":visible")) {
jQuery('.arrow', jQuery(this)).removeClass("open");
jQuery(this).parent().removeClass("active");
sub.slideUp(350, function () {
handleSidenarAndContentHeight();
});
} else {
jQuery('.arrow', jQuery(this)).addClass("open");
jQuery(this).parent().addClass("open");
sub.slideDown(350, function () {
handleSidenarAndContentHeight();
});
}
e.preventDefault();
});
Working with a 2 second timeout should do the trick!
jQuery(document).ready(function(){
// Open Parent here
setTimeout(function(){
// Open Child here
}, 2000)
});
There is a simple javascript function you can use, the setTimeout function.
The code follows like this :
setTimeout(function() {yourFunctyion();}. delayTimeInMiliseconds);
This will call your function after the number of second(in ms).
There is also a plugin I've used. It has oneTime and everyTime methods.

how I can random a list with jQuery before page get loaded?
i found this example on the web: http://whatanswered.com/websites-javascript/random-elements-using-jquery.php
(you must scroll down a bit to see)
but it works only after mouse press the button. *this is my problem, i need it to work atomatically before the page is getting loaded.
Any ideas?
I copied the code in this FIDDLE, if anyone would like to help, it might be usefull!
$(function() {
$('button').click(function() {
$("div.list").randomize("div.cat");
});
});
(function($) {
$.fn.randomize = function(childElem) {
return this.each(function() {
var $this = $(this);
var elems = $this.children(childElem);
elems.sort(function() { return (Math.round(Math.random())-0.8); });
$this.remove(childElem);
for(var i=0; i < elems.length; i++)
$this.append(elems[i]);
});
}
})(jQuery);
You can just call the randomize plugin when the page loads - be aware though the plugin needs to have been loaded before hand:
$(function() {
$("div.list").randomize("div.cat");
});
Updated fiddle: http://jsfiddle.net/yNChm/1/
The easiest way is to call the randomize() function after the document.ready event has fired:
$(document).ready(function() {
$("div.list").randomize("div.cat");
});
You should be able to accomplish this by doing a $(window).ready, or something along those lines:
$(function() {
console.log('Yo');
$("div.list").randomize("div.cat");
});
Make sure you register the plugin first!
I'm new to javascript and jquery and I am trying to make a video's opacity change when I mouseover a li item. I know 'onmouseover' works because I have tested using the same jquery I use to scroll to the top of the page onclick.
The problem seems to be the syntax to check and update the style of the video div is not working. I adapted the code from a lesson on codeacademy and don't see why it work:
window.onload = function () {
// Get the array of the li elements
var vidlink = document.getElementsByClassName('video');
// Get the iframe
var framecss = document.getElementsByClassName('videoplayer1');
// Loop through LI ELEMENTS
for (var i = 0; i < vidlink.length; i++) {
// mouseover function:
vidlink[i].onmouseover = function () {
//this doesn't work:
if (framecss.style.opacity === "0.1") {
framecss.style.opacity = "0.5";
}
};
//onclick function to scroll to the top when clicked:
vidlink[i].onclick = function () {
$("html, body").animate({
scrollTop: 0
}, 600);
};
}
};
Here is a jsfiddle you can see the html and css:
http://jsfiddle.net/m00sh00/CsyJY/11/
It seems like such a simple problem so I'm sorry if I'm missing something obvious.
Any help is much appreciated
Try this:
vidlink[i].onmouseover = function () {
if (framecss[0].style.opacity === "0.1") {
framecss[0].style.opacity = "0.5";
}
};
Or alternatively:
var framecss = document.getElementsByClassName('videoplayer1')[0];
Or, better, give the iframe an id and use document.getElementById().
The getElementsByClassName() function returns a list, not a single element. The list doesn't have a style property. In your case you know the list should have one item in it, which you access via the [0] index.
Or, given that you are using jQuery, you could rewrite it something like this:
$(document).ready(function(){
// Get the iframe
var $framecss = $('.videoplayer1');
$('.video').on({
mouseover: function () {
if ($framecss.css('opacity') < 0.15) {
$framecss.css('opacity', 0.5);
}
},
click: function () {
$("html, body").animate({
scrollTop: 0
}, 600);
}
});
});
Note that I'm testing if the opacity is less than 0.15 because when I tried it out in your fiddle it was returned as 0.10000000149011612 rather than 0.1.
Also, note that the code in your fiddle didn't run, because by default jsfiddle puts your JS in an onload handler (this can be changed from the drop-down on the left) and you then wrapped your code in window.onload = as well. And you hadn't selected jQuery from the other drop-down so .animate() wouldn't work.
Here's an updated fiddle: http://jsfiddle.net/CsyJY/23/
I'm using object literals on my project. I'm targeting selecting with jquery. It works fine the first time but when the part I'm targeting is reloaded with AJAX I can't target those element anymore. But I look into firebug they're there...
I'm even doing console.log() to test if my code works and it works but it just doesn't want to pick those. So in order for it to work, I have to refresh the entire browser.
Do you know what's the deal with AJAX dom reload and selectors.
I think it's something to do with the DOM reloading and redrawing itself or something along those lines...
Here is my code:
Module.editWishlistTitle = {
wishListContent: $('.mod-wish-list-content'),
title: $('.title').find('h2'),
titleTextField: $('#wishlist-title-field'),
titleInnerContainer: $('.title-inner'),
editTitleForm: $('.edit-title-form'),
submitCancelContainer: $('.submit-cancel'),
notIE9: $.browser.msie && $.browser.version < 9,
edit: function () {
var fieldTxt = this.titleTextField.val(),
editForm = this.editTitleForm,
titleParent = this.titleInnerContainer,
fieldCurrentTitle = this.title.text();
this.titleTextField.val(fieldCurrentTitle);
this.submitCancelContainer.removeClass('hidden');
if (!this.notIE9) {
editForm.css('opacity', 0).animate({ opacity: 1 }).removeClass('hidden');
titleParent.addClass('hidden').animate({ opacity: 0 });
console.log(editForm);
} else {
editForm.removeClass('hidden');
titleParent.addClass('hidden');
}
}
init: function () {
var self = this;
console.log(this.editTitleForm);
//edit
this.wishListContent.delegate('.edit-title a', 'click', function (e) {
self.edit();
e.preventDefault();
});
};
If you are replacing an element on the page, you are destroying the original reference to the element. You need to redo the reference to point to the new element.
Create a new method in your code that (re)initializes the references you need. Instead of adding them in the odject, set them in the method.
Basic idea:
Module.editWishlistTitle = {
wishListContent: $('.mod-wish-list-content'),
title: $('.title').find('h2'),
//titleTextField: $('#wishlist-title-field'),
...
...
initReferences : function(){
this.titleTextField = $('#wishlist-title-field');
},
...
...
init: function () {
this.initReferences();
...
...
And when your Ajax call comes back you just need to call initReferences again.
After DOM ready, if you inject any data / class / id will not be available in DOM, so better you use live or delegate to get your new data access.
http://api.jquery.com/delegate/
Best to use delegate, that will take care your new data loaded after dom ready, that way you can avoid to refresh /reload your page.
I have a script that runs a slideshow for my page. I'm trying to use .delegate() to insert a new set of images shown within the slideshow including its thumbnails. I'm using a .load() function to load an external <div> to replace some HTML within the active page. I also have buttons with IDs, (#kick1, #kwick2, etc.) that determine what set of slide show is loaded.
jQuery("#kwick2").click(function () {
jQuery("body").delegate('#slideshow', 'click', function() {
jQuery('#slideshow').load('/design.html #design');
)};
)};
Pretty sure the syntax is all wrong. Can someone help me?
The #slideshow div is something I created to contain some other divs directly
effected by the slideshow script. Within div ID #slideshow are
<div class="main_image">, <div class="desc"> and <div class="image_thumb">.
These are being replaced directly when you click a KWICK button, they are all pretty much self explanatory, image thumb has and unordered list with image links.
You should not re-deligate every time you click the button. You are doing the wrong.
Instead what you should have is something like:
var foobar = (function () {
var func , mod1 , mod2;
mod1 = function () {
/* do something in state 1 */
};
mod2 = function () {
/* do something in state 2 */
};
return {
state: function (e) {
switch (this.id){
case 'kwick1':
func = mod1;
break;
case 'kwick2':
func = mod2;
break;
}
},
callback: function (e) {
func.call();
}
}
})();
jQuery("#kwick1").click( foobar.state ); // and you really should delegate this
jQuery("#kwick2").click( foobar.state );
jQuery("body").delegate('#slideshow','click', foobar.callback);
Or something similar to this ..
And no , i did not test this code. It is written to explain the concept, not to spoon-feed people.
not sure if i have understood the question well, anyway you have to specify what event you are delegating
jQuery("#kwick2").click(function () {
jQuery("body").delegate('#slideshow',"click", function(){
jQuery('#slideshow').load('/design.html #design');
)};
)};
delegate
