Select link right after the one i just clicked - javascript

also threw it up on jsbin: http://jsbin.com/ohazo/2
but the code on jsbin is the old code, so overlay_nextimg is overlay_content.click in the javascript on jsbin
Jquery lightbox, grab next link from the one we just clicked, take it's href, fade out the current image, and load in the next img.
Also, how would i go about keeping the overlay_content centered? when changing images, have it animate to the new position? i was gonna tackle that next, but i'm here so why not.
Jquery and Html, i've changed the overlay_content.click that we were using before to overlay_nextimg, to be less confusing.
Jquery:
$(function (){
$('a.lightbox').click(function() {
var imghref = $(this).attr("href");
loadImage(imghref);
alert(imghref)
return false;
});
$('.overlay_nextimg').click(function (){
var currlink = $("a[href='" + $(".overlay_content img").attr("src") + "']");
var nextlink = $(currlink).next(".lightbox");
var prevlink = $(currlink).prev(".lightbox");
alert(nextlink);
loadImage(nextlink);
});
$('.overlay_previmg').click(function (){
var currlink = $("a[href='" + $(".overlay_content img").attr("src") + "']");
var nextlink = $(currlink).next(".lightbox");
var prevlink = $(currlink).prev(".lightbox");
alert(prevlink);
loadImage(prevlink);
});
function loadImage(href, prevlink, nextlink) {
var currentImg = $('.overlay_content img');
var img = new Image();
var docHeight = $(document).height();
$('.overlay_content').delay(300).fadeIn(400);
$(".overlay_bg").height(docHeight).fadeIn(400, function(){
$(img).load(function () {
$(img).hide();
$('.overlay_content').html(img);
$(img).fadeIn('slow');
}).error(function () {
$('.overlay_content').html("you SUCK at Javascript")
}).attr('src', href);
})
}
$('.overlay_bg').click(function (){
$(this).fadeOut(300);
$(".overlay_content").fadeOut(300, function(){
$(this).html('');
});
});
});
HTML:
<div class="overlay_bg"></div>
<div class="overlay_content"></div>
<h1>links</h1>
Load a water color image.
Load a library book, yeah.
from the interweb.
internet image.
HUGE

Please add more of the code/HTML - Is $("overlay_content").click(...) the function you need to fix?
You can use the eq() selector to get the n-th a.lightbox on the page. But obviously you'll need to track what link you're currently on., i.e.
$("a.lightbox:eq(1)")
Or - using the src of the image currently being displayed, find out which link was clicked and move next from there, i.e.
$("a.lightbox[href='" + currentImg.attr("src") + "']").next()

Resize youtube video (on page and onclick)

I'm trying to use a script in which I feature some tumblr video posts (those tagged with "featured" word) but I have two problems:
1) I don't know how set a size for the videos on the page (ideal 300 width). they are stuck on 400px.
2) I'd like the videos to grow to 1000px width, when people click play.
My tumblr is on cookjs.tumblr.com
can anyone help? thank you so much in advance!
<script>
if ($('p img').length > 0)
$(".textpost").css("overflow","hidden");
var rssurl = '/tagged/{text:Featured Tag}/rss';
$.get(rssurl, function(data) {
var $xml = $(data);
var vari = 0;
$xml.find("item").each(function() {
var $this = $(this),
item = {
title: $this.find("title").text(),
link: $this.find("link").text(),
description: $this.find("description").text(),
pubDate: $this.find("pubDate").text(),
author: $this.find("author").text()
}
vari = vari +1;
if(vari <4){
$('.featured-subhead').append('<section class=""><h2>
</h2>
<div class="">' + item.description + '</div><div class="">
Read More</div></section>');
}
});
});
</script>
So the right way of doing this is probably through the YouTube IFrame Player API. You'll be specifically interested in the onStateChange event listener. There's another way that I've done this that you may be interested in; here's the jQuery (since I was new to JS at the time):
$('iframe[src*="youtube.com"]').each(function(){
var videoURL = $(this).attr('src');
var videoID = videoURL.substr(videoURL.length - 11,11);
var thumbURL = 'http://img.youtube.com/vi/' + videoID + '/0.jpg';
$(this).wrap("<div class='video'></div>");
var videoDiv = $(this).parent();
videoDiv.css('background-image', 'url("' + thumbURL + '")').attr('id',videoID);
var heightUnit = $(this).height()*.25;
var widthUnit = $(this).width()*.20;
videoDiv.css('background-position', '0%, -' + heightUnit + 'px');
$(this).remove();
var playButton = $('<img />').attr({
'class': 'button',
'src':'playbutton.png'
}).css({
'width':widthUnit,
'margin-top': '-' + (widthUnit/2)*.783,
'margin-left': '-' + (widthUnit/2)
});
videoDiv.append(playButton);
playButton.on("click",function(){
$(this).css('opacity','0');
var newFrame = $('<iframe />').attr({
'src': 'http://www.youtube.com/embed/' + videoID + '?autoplay=1',
'frameBorder':'0'
});
videoDiv.append(newFrame);
});
});
What this is doing is grabbing the video url from each video on the page, removing the iframe and replacing it with the thumbnail (hosted by YouTube) and a separate clickable button. You can attach any handler you want to the button (even create your own button) but you'll also want to reload a new iframe with the embed url and append ?autoplay=1 to the end, which will start the video.
Here's a demo of this effect; something I coded a few years ago.
you can simply change the iframe height and width by using
function resizeIfrmae()
{
// your ifrmae id or you can pass id via function param
// resizeIfrmae(id) like this
$('#youtube_iframe_id').css('width','150');
$('#youtube_iframe_id').css('height','150');
}
onclick call this function
resizeIfrmae();

How to get JQuery to swap picture prior to page being displayed

I've got the following script which swaps the source of an image. However currently this happens after the page loads so the user experiences a split second of seeing one picture before it switches to the correct image.
<script>
window.onload = function () {
var winnerName = $("#leaderboard tr td:eq(1)").text().trim();
$("#pictureDiv img").attr("src", "/Content/Images/" + winnerName + ".jpg");
};
</script>
How can I get the image to switch before loading?
Note I've also tried:
<script>
$(function() {
var winnerName = $("#leaderboard tr td:eq(1)").text().trim();
$("#pictureDiv img").attr("src", "/Content/Images/" + winnerName + ".jpg");
});
</script>
but this results in the same thing occurring
Both of the window.onload or jQuery's $(function()... functions are only called when the page is fully loaded.
The closest you could get is to add the function to the images onload handler.
<img src="..." onload="function() {...}">
But I suspect the same will still occur.
If the image's src needs to be set using javascript then you could try dynamically creating the image and adding it in where you need it, using something like the following.
$(function() {
var winnerName = $("#leaderboard tr td:eq(1)").text().trim();
var imgElement = $('<img>').attr("src", "/Content/Images/" + winnerName + ".jpg");
$("#pictureDiv").append(imgElement);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="pictureDiv"></div>

script works in jsfiddle but not in site

I have seen others ask this question but I couldn't find an answer that worked for me.
I posted a question a while back and someone sent me this jsFiddle: http://jsfiddle.net/r043v/LgXQX/1/
It does exactly what I need it to and the site says it's perfectly valid, but it's not working when I paste it into my document. I read about the extra invisible characters it will add when you c+p so I used jslint and it said I had gotten rid of them, but it still isn't working.
Here is the code as it is in my page (I started from scratch after it didn't work the first time so that I would be sure nothing else in my code was messing it up)
<!DOCTYPE html>
<head>
<link rel="stylesheet" href="style3.css">
<script type=”text/javascript” src="https://ajax.googleapis.com/ajax/libs/jquery/1.5.2/jquery.min.js"></script>
<script>
$("#issues > li").click(function () {
var $img = $("#theimg");
var $li = $(this);
var newsrc = "";
newsrc = $li.data("img");
if (newsrc === undefined) newsrc = "issue" + $li.index() + ".jpg";
var loadstep = 0;
function endstep() { // end of preload or hide
if (++loadstep === 2) // if the preload is done and hide too, change src and show picture
$img.attr("src", newsrc).animate({
opacity: 1
});
}
// preload picture
var $tmpimg = $("<img/>", {
src: newsrc
}).on("load", endstep);
// hide container picture
$img.animate({
opacity: 0
}, endstep);
});
</script>
</head>
The css file only has what's in the jsFiddle and the body is copied and pasted from the html section in the fiddle. Any insight would be greatly appreciated!
You need to load the script in a $(document).ready() handler. Fiddle adds it for you. Hence it is working there.
$(document).ready(function () {
$("#issues > li").click(function () {
var $img = $("#theimg");
var $li = $(this);
var newsrc = "";
newsrc = $li.data("img");
if (newsrc === undefined) newsrc = "issue" + $li.index() + ".jpg";
var loadstep = 0;
function endstep() { // end of preload or hide
if (++loadstep === 2) // if the preload is done and hide too, change src and show picture
$img.attr("src", newsrc).animate({
opacity: 1
});
}
// preload picture
var $tmpimg = $("<img/>", {
src: newsrc
}).on("load", endstep);
// hide container picture
$img.animate({
opacity: 0
}, endstep);
});
});

Fading background images from an array

$('.pictures a').click(function () {
var path = "place/of/images";
var pics = ['pic1.JPG',
'pic2.JPG',
'pic3.JPG',
'pic4.JPG'];
var i = 0;
var numberOfPics = pics.length - 1;
var vaheta = setInterval(function () {
$('body').css({ backgroundImage: 'url(' + path + pics[i] + ')' });
if (i == numberOfPics) {
i = 0;
} else {
i++;
}
}, 3000);
return false;
});
This is the code that is currently just changing background images for me. Now I found a topic here where it says you have to load the pictures as etc and there was this fiddle, http://jsfiddle.net/RnqQL/1/, this one, that is exactly what I want to do, but I don't quite know how to combine these two (my code and the fiddle).
The images will actually later be loaded with JSON from the server depending on the id of the link the person clicked to get this slideshow, this is too overwhelming for me...
I created fiddle at http://jsfiddle.net/xMrp3/1/
You can modify and use. I try to explain what i did with comments.
$('.pictures a').click(function () {
var path = "http://elegantthemes.com/preview/InStyle/wp-content/uploads/2008/11/";
$("#wrap").empty(); // clear wrap div content
$.getJSON('/echo/json/', function (pics) { // get json data
var pics = ['s-1.jpg', 's-5.jpg', 's-3.jpg']; // i override json response for demo
$.each(pics, function(i, pic) { // loop through pics array
$('<img/>').attr('src', path + pic).appendTo($("#wrap")); // append all images to #wrap div
});
if (animTimeout == null) // if we didnt started anim yet
anim(); // start animation
});
return false;
});
var animTimeout = null;
function anim() {
$("#wrap img").first().appendTo('#wrap').fadeOut(500);
$("#wrap img").first().fadeIn(500);
animTimeout = setTimeout(anim, 700);
}

dynamic <img> refresh with javascript

I'm trying to get an user input image to refresh say every two seconds. The javascript gets user input for an URL and the javscript adds it to the page. Then the images loaded need to refresh every 2 seconds but i can't get it to refresh properly without refreshing the whole page or reloading from the cache:
function getImg(){
var url=document.getElementById('txt').value;
var div=document.createElement('div');
div.className="imageWrapper";
var img=document.createElement('img');
img.src=url;
div.appendChild(img);
document.getElementById('images').appendChild(div);
return false;
}
setInterval(function(){
$('img').each(function(){
var time = (new Date()).getTime();
$(this).attr("src", $(this).attr("src") + time );
});
}, 2000);
any ideas?
When you need to force reload the resource, you have to add a dymmy queryString at the end of your url:
<img id="img1" src="myimg.png?dummy=23423423423">
Javascript:
$('#img1').attr('src','myimg.png?dummy=23423423423');
and change the dummy value for each refresh
Your premise seems good, not sure why it isn't working. Why mixing and matching jQuery with non-jquery? This is a modification of your code, but it is a working example. You should be able to adapt it for your purpose.
http://jsfiddle.net/zr692/1/
You can create elements via jQuery easily. See the modified getImg function I created. Ia also switched from attr to prop which is the recommended means of accessing the src attribute in jQuery 1.7+.
function getImg() {
var url = 'http://placehold.it/300x300/123456';
var $div = $('<div />');
var $img = $('<img />', { src: url });
$div.append($img);
$('body').append($div);
}
getImg();
var interval = setInterval(function() {
$('img').each(function() {
var time = (new Date()).getTime();
var oldurl = $(this).prop('src');
var newurl = oldurl.substring(0, oldurl.lastIndexOf('/') + 1) + time.toString().substr(7, 6);
$('#output').html(newurl);
$(this).prop('src', newurl);
});
}, 2000);
Put the image in a container as:
<div id="container"><img src=""../> </div>
then simply update the content of the container as:
$('#container').html('<img src="newSource"../>');
