How to add jquery events to added classes? - javascript

I am trying to create an image gallery, I am using numbers instead of left/right arrows. At the moment, I am trying to get it working with only 2 image (i.g 2 numbers)
this is the html . the id page, is the highlighted number
<div class="grid_1 pagelink" id="page"><p>1</p></div>
<div class="grid_1 pagelink"><p>2</p></div>
the first time the page loads, the code below works. so when I click on link 2 the the code bellow runs fine. But then I want the same code to be triggered when I click back on the first link; but when I do that, the page refreshes by ignoring the code bellow:
$('.pagelink').live('click', function(e){
e.preventDefault();
var frame = $(this).text() - 1;
var frames = 240 * frame;
// $('#gal').animate({marginLeft:'500px'},'slow');
$('#gal').animate({marginLeft: "+="+frames+'px'},'slow');
$(this).attr('id', 'page').removeClass('pagelink');
$('#page').addClass('pagelink').removeAttr('id','page');
// $('#book').animate({ left: '50' });
})
I thought that the .live() would do that for me but it is not working.
I hope you could help
thank you

Previous, this is because you are removing the class of link "pagelink" which were used to map the clicked event.
Also, use another class instead of id(#page) to identify the #page link, id might be problem if its already assign to other link. like
$(this).removeClass('pagelink').addClass('page');
$('.page').addClass('pagelink').removeClass('page');

live should work fine. i think you have a bug in your code, and its probably here:
$(this).attr('id', 'page').removeClass('pagelink');
$('#page').addClass('pagelink').removeAttr('id','page');
what exactly are you trying to accomplish with this code?
when you click on page2, the you set the div's id to be page, but now you have 2 elements with an id of page, and when you select that id, you get the first one (ie page1), but you still remove the class pagelink from page2
in other words, the bug is that at some point you will have 2 elements with the same id (and ids must be unique btw) so when you select that id with $('#page') you always get the first one

Remove "#comments" from dynamically loaded URLs?

I've got a problem where all the dynamic links on my homepage have "#comments" at the end, making it so when the user clicks their screen is annoyingly jolted down to the 'Comments' section each time rather than staying on top.
Example URL:
https://example.com/441447279/amazing-art/#comments
Is there a way to dynamically strip them of the 'comments' part via jQUery?
They're always the SECOND link in a unique class <p class="g1-meta entry-meta entry-byline entry-byline-s entry-byline-with-avatar">
so I was thinking something like
var linkURL = $(".g1-meta.entry-meta.entry-byline.entry-byline-s.entry-byline-with-avatar").find("a").prop('href');
but I don't know how to make it retrieve the SECOND link instead of the 1st.
And I don't know where to go from there... Help appreciated.
Use this
//The key here is to use nth-of-type selector
$(".g1-meta.entry-meta.entry-byline.entry-byline-s.entry-byline-with-avatar").find("a:nth-of-type(2)").each(function(){
let link = $(this).prop('href').replace('#comments','');
$(this).prop('href',link)
})
Or without jQuery
Array.from(document.querySelectorAll('.g1-meta.entry-meta.entry-byline.entry-byline-with-avatar')).forEach(function(node){
let anchorNode = node.querySelectorAll('a')[1];
anchorNode.href= anchorNode.href.replace('#comments','');
})

Reverting to original element ID

I have li blocks which onclick will change class ID as follows:
onclick = "document.getElementById('procblock1').id = 'procblock1Clicked';"
"document.getElementById('procblock2Clicked').id = 'procblock2';"
"document.getElementById('procblock3Clicked').id = 'procblock3';"
"document.getElementById('procblock4Clicked').id = 'procblock4';"
The line document.getElementById('procblock2Clicked').id = 'procblock2'; should revert any clicked elements (blocks) back to their original ID names.
The code works for changing the original id to the clicked id but doesn't have any effect in reverting previously clicked to the original as per lines 2,3 & 4.
I have searched hard for similar questions but can find nothing that covers this specific issue.
#Matthias - I acted upon your advice and came up with a very simplified jquery solution :
`$(function() {
$(".showinfo").click(function() { //using class instead of ID
$(".showinfo").removeClass("clicked"); //Remove all existing clicks
$(this).addClass("clicked"); //add the class to the clicked element });
});`
Posted solution in case anyone else has same query. Your help was appreciated.
If this really is part of the code you're using lines 2-4 won't work; onclick will only handle the first line. You should wrap it as a function to be called onclick, like onclick = "doStuff()" and add a function doStuff () {/* your code here */}. But that's just guessing as you only provide some part of the code in question.
In addition would be good to know what you want to achieve - in case you want to mark clicked elements, it would be a cleaner approach to add a class, e.g. "clicked" or "active", that you simply remove later on instead of changing ids.

JQuery Cookies with dynamic div ID's

I hope you guys can give me a push in the right direction as this problem has been eating me up all day now..
What I'm basicly trying to accomplish is this. I have several div's on a page that can be collapsed independently from eachother with the use of a button. Every div has it's own specific ID, generated with a string of static text, and a numeric value based on a auto-incremented database-value. This ensures I never have two div's with the same ID on one page. To target each specific div with Javascript (jQuery) I use the following code:
http://jsfiddle.net/LU7QA/0/
This works really well and does what it's supposed to do. Only there is one problem. On every page frefresh, every div that was opened is closed. Everything resets, and that's why I want to use JQuery Cookies in this construction. Only problem is, I know how it works, but I can't get it to work in this specific construction as it has to deal with a completely unique ID every time and needs to store the values of that particular ID.
As seen here: http://jsfiddle.net/LU7QA/1/
I tried to fiddle around with it but I can't seem to get it working properly and I'm starting to lose my sight on the problem..
<div>
<button class="button_slide" value="1">Show hide</button>
</div>
<div id="slidingDiv_1" class="slidingDiv">Stuff</div>
<div>
<button class="button_slide" value="2">Show hide</button>
</div>
<div id="slidingDiv_2" class="slidingDiv">Stuff</div>
function initMenu() {
$(".slidingDiv").hide();
// Toggle Field
$(".button_slide").click(function(){
//alert($(this).val()); debugging purposes
var sliding_id = $(this).val();
div_sliding_id = '#slidingDiv_'+sliding_id;
$(div_sliding_id).next().slideToggle('slow', function() {
$.cookie(div_sliding_id, $(this).is(':hidden') ? "closed" : "open");
return false;
});
});
$('.button_slide').each(function() {
var sliding_id = $(this).val();
div_sliding_id = '#slidingDiv_'+sliding_id;
if ($.cookie(div_sliding_id) == "open") $(this).next().show();
});
}
jQuery(document).ready(function() {initMenu();});
May you have missed a dot on the last *button_slide* declaration?
Btw, look at https://code.google.com/p/sessionstorage/

How to remove a class via JavaScript (NOT jQuery) at Wordpress

I need your help at a problem of my Wordpress Webpage. My Wordpress-page is an Single-Page-App with 3 different boxes of content. The left and center boxes are static, the right one changes its content by clicking on links of the other boxes. I decided, to load all the content in the right box and show them with the CSS-command visibility. With a combination of pathJS and JS, i want the URL to change by clicking on the links. So far so good - all works fine, but i dont get managed via my JS-Function to remove the shown-class.
My script looks like this:
<script>
function showDetailContent(showid) {
//suche objekt right_id -> was du zeigen willst -> getelementbyid
alert("1");
var id = document.getElementsByClassName('shown');
alert("2");
id.classList.remove('shown');
alert("3");
document.getElementByID("right_" + showid).classList.add('shown');
alert("4");
}
//var c = document.getElementById('content'); -->do the function :)
Path.map("#/?p=<?php the_id();?>").to(function () {
showDetailContent(<?php the_id();?>);
});
Path.listen();
</script>
The alerts are just my way of "debugging". I think its not the best way to debugg, but i am very new in the world of prorgamming and this is kind of easy.
However, the first two alerts are shown, if i activate a link. So the (first) mistake is on the line
id.classList.remove('shown');
Normally, the right-box is hidden, so that only one content is load.
Do you understand my problem till here?
I would appreciate fast help!
Greetings, Yannic! :)
Look at this : http://snipplr.com/view/3561/ to know remove class pure javascript
getElementsByClassName gets multiple elements, try:
var id = document.getElementsByClassName('shown')[0];
Or iterate through them if you want to remove class from all elements with class shown;

Dynamically change Tweet Button "data-text" contents

This question comes very closely to what I'm after: Replace an Attribute in the Tweet Button with Jquery
However, the suggested solution works just once. That is, I cannot use it in my switch statement like this:
switch(element.id)
{
case "t1":
$(document).ready(function(){
$('a[data-text]').each(function(){
$(this).attr('data-text', Text_Variant_1);
});
$.getScript('http://platform.twitter.com/widgets.js');
});
break;
case "t2":
$(document).ready(function(){
$('a[data-text]').each(function(){
$(this).attr('data-text', Text_Variant_2);
});
$.getScript('http://platform.twitter.com/widgets.js');
});
...
}
What happens is that the data-text attribute is set according to whichever case happens first and doesn't change afterwards.
How can I change data-text attribute of a Tweet Button as many times as I need?
Update: here's the page I'm working on: http://zhilkin.com/socio/en/
The Traits table can be safely ignored. What I want to do with the Sociotypes table is that when you click on a type, the data-text of the Tweet Button below the description on the right should be changed accordingly.
Right now it works like this: if I hover on or click "Don Quixote", then data-text is set to "... Don Quixote ...", and it stays the same if I click "Dumas" later. And vice versa: if I hover on or click "Dumas", then data-text is set to "... Dumas ..." and doesn't change if I click "Don Quixote". (Other types are empty at the moment.)
So, the Tweet Button is only changed the first time I run the script, but I need it to be updated as many times as the type changes.
I struggled with this for a couple of hours this morning, but finally got it working! The problem is essentially that you can only include the twitter widgets.js script once in the page, and that script evaluates the data-text attribute on load. Therefore, in your example, you dynamically set the data-text attribute before loading the script, which will work as expected. However, you can then make no further updates as the script has already run.
I saw this article suggesting you can call twttr.widgets.load() again at runtime to re-evaluate and re-render the buttons, however that didn't work for me. This is because that function re-evaluates <a> tags, not <iframe> tags!
So the solution, as pointed out here, is to completely remove the rendered <iframe> from the DOM, then make a new <a> element with all the appropriate attributes before calling twttr.widgets.load() to finally re-evaluate it and turn it into an <iframe>.
Please see this fiddle for a working example!
You can also use Twitter's createShareButton API call:
function callAsRequired(){
var nodeID = 'YourTwitterNodeID'
//Remove existing share button, if it exists.
var myNode = document.getElementById(nodeID);
while (myNode.firstChild) {
myNode.removeChild(myNode.firstChild);
}
//Create button and customise
twttr.widgets.createShareButton(
'http://your.custom.url.here/',
document.getElementById(nodeID),
{
count: 'none',
text: 'Your custom tweet here'
});
}
since you are using each loop you can use if statements instead:
$(document).ready(function(){
$('a[data-text]').each(function(){
if (theCase == 1) {
$(this).attr('data-text', Text_Variant_1);
}
else if (theCase == 2) { ... }
})
});
