I tried to name the title as best I could. A little difficult for me to explain.
I'm having an issue with some code I'm writing (which runs in a widget on my wordpress site.) What I've written here emulates this issue. Just fyi I'm very new to jquery, JS, etc.
What I'm trying to do is set the variable "thumb" to the element after "widget-code". It works, however it's only finding that element ("thumb-class") in "wordpress-post1"
The console output is:
wordpress-post1
wordpress-post1
wordpress-post1
But it should be:
wordpress-post1
wordpress-post2
wordpress-post3
This is the actual code
<div class="wordpress-post1">
<div id="widget-code">
<script>
$(document).ready(function(){
var thumb = $("#widget-code").next();
console.log(thumb[0].parentElement.className);
});
</script>
</div>
<div class="thumb-class">
</div>
</div>
<div class="wordpress-post2">
<div id="widget-code">
<script>
$(document).ready(function(){
var thumb = $("#widget-code").next();
console.log(thumb[0].parentElement.className);
});
</script>
</div>
<div class="thumb-class">
</div>
</div>
<div class="wordpress-post3">
<div id="widget-code">
<script>
$(document).ready(function(){
var thumb = $("#widget-code").next();
console.log(thumb[0].parentElement.className);
});
</script>
</div>
<div class="thumb-class">
</div>
</div>
I'm going to try and clarify a little more:
This code is placed in an html widget which the wordpress theme I'm using provides. It hooks into each post. This is the only place I can put code, and this is the only code I've written. (I haven't altered the theme's files in any way.)
I have no control over the name of the classes or IDs. And they're dynamic. An unlimited number of posts could exist. Therefore I can't hardcode anything.
In order for this code to work correctly it'll need to find the sibling of the "widget-code" element in only the post it's running from.
This is the link to the code on JSFiddle: http://jsfiddle.net/pattnvy3/
Would appreciate any help on the matter.
If you want a nasty hack, try
<div class="wordpress-post1">
<div id="widget-code">
<script>
$(document).ready(function(){
var c = window['widget-code-counter'] || 0;
window['widget-code-counter'] = ++c;
var className = 'wordpress-post' + c;
console.log(className);
});
</script>
</div>
<div class="thumb-class">
</div>
</div>
Demo: Fiddle
It will give the container class wordpress-post1, then you can use it to find any of the descendant element.
As per the immediate comments, it is invalid markup to use an id for multiple elements. That said, changing your id to a class such that:
<div class="wordpress-post[some-number-here]">
<div class="widget-code">
</div>
<div class="thumb-class">
</div>
</div>
would allow you to to a jQuery selector like so:
$('.widget-code').each(function (){
var thumb = $(this).next();
console.log(thumb[0].parentElement.className);
});
However, if I may make a recommendation, I would say that you tag each of your wordpress-post divs with the class "wordpress-post" and then have a more specific id which is the value you want to print.
Then it would look like this:
<div id="wordpress-post[some-number-here]" class="wordpress-post">
<div class="widget-code">
</div>
<div class="thumb-class">
</div>
</div>
and your javascript like this (with jQuery):
$('.widget-code').each(function (){
var post = $(this).closest('.wordpress-post');
console.log(post.attr('id'));
});
or even simpler:
$('.wordpress-post').each(function (){
console.log($(this).attr('id'));
});
depending on the needs you have. If you have any questions as to what you need, feel free to comment and I will get back to you as soon as I can.
A pure javascript method:
This is just a workaround since you have no control over ids or classes, this will target all div elements on the page, loop through them and search for any that contains wordpress-post in the class name.
window.onload=function(){
var posts=document.getElementsByTagName('div');
for(var i=0; i<posts.length; i++){
if(posts[i].className.indexOf("wordpress-post")> -1){
console.log(posts[i].className);
//Snippet Use
alert(posts[i].className);
}
}}
<div class="wordpress-post1">
<div id="widget-code"></div>
<div class="thumb-class"></div>
</div>
<div class="wordpress-post2">
<div id="widget-code"></div>
<div class="thumb-class"></div>
</div>
<div class="wordpress-post3">
<div id="widget-code"></div>
<div class="thumb-class"></div>
</div>
If you have any questions, please leave a comment below and I will get back to you as soon as possible.
I hope this helps. Happy coding!
This can help if you want to have multiple IDs:
$(document).ready(function(){
$("[id^=widget-code]").each(function(){
console.log(this.parentElement.className);
});
});
But, still multiple same Ids are not recommended.
FIDDLE
Update: Declare a global variable var i=0; and keep increment it like :
<div class="wordpress-post1">
<div id="widget-code">
<script>
var i=0;
$(document).ready(function(){
var thumb = $("[id^=widget-code]").next();
console.log(thumb[i++].parentElement.className);
});
</script>
</div>
<div class="thumb-class">
</div>
</div>
<div class="wordpress-post2">
<div id="widget-code">
<script>
$(document).ready(function(){
var thumb = $("[id^=widget-code]").next();
console.log(thumb[i++].parentElement.className);
});
</script>
</div>
<div class="thumb-class">
</div>
</div>
<div class="wordpress-post3">
<div id="widget-code">
<script>
$(document).ready(function(){
var thumb = $("[id^=widget-code]").next();
console.log(thumb[i++].parentElement.className);
});
</script>
</div>
<div class="thumb-class">
</div>

I am trying to pull certain item IDs based on if they have an image tag or not. For a given input like the one below:
<div id="ID_1">
<p><img src="image4.png"></p>
</div>
<div id="ID_2">
</div>
<div id="ID_3">
<p><img src="image6.png"></p>
</div>
<div id="ID_4">
<p><img src="image4.png"></p>
</div>
I could get something like:
ID_1: image4.png
ID_2:
ID_3: image6.png
ID_4: image4.png
I am not too familiar with HTML or Javascript, so any help or resources that someone may have or know will be greatly appreciated.
I would recommend using jQuery for something like this
(dont forget to include jquery in the html head)
Html =>
<div id="divContainer" >
<div id="ID_1">
<p><img src="image4.png"></p>
</div>
<div id="ID_2">
</div>
<div id="ID_3">
<p><img src="image6.png"></p>
</div>
<div id="ID_4">
<p><img src="image4.png"></p>
</div>
</div>
Javascript =>
const doesContainImg = [];
$(".divContainer div").each(function() {
// check for an img
if ($(this).find("img").length) {
// store id in array that contains ids that have imgs
doesContainImg.push($(this).attr("id"));
}
});
that should work, if it does not let me know!
Add a class on those div.
Let's say you have the class "image-div".
We can use this class to see if the divs contain an image or not.
JQUERY:
$(".image-div").each(function(){
if($(this).find('img').length){
//if this div contains an image do something.
}
});
You can attach this code to an event and use it
I have a set of divs, and need to clone the link from the top and insert into the last div (mobile-link). It is either cloning the links from all of the divs, and then inserting all of them at once, or if I use :eq(0), it's putting the first link into all of the divs.
<div class="course">Accounting</div>
<div class="start-date">1-1-2017</div>
<div class="credits">4</div>
<div class="location">Online</div>
<div class="mobile-link"></div>
<div class="course">Business</div>
<div class="start-date">1-1-2017</div>
<div class="credits">3</div>
<div class="location">Online/Campus</div>
<div class="mobile-link"></div>
<script>
$(".course a:eq(0)").clone().appendTo(".mobile-link");
</script>
What do I need to change to make this work properly?
You need to process each anchor separately:
$(".course").each(function() {
var myLink = $(this).find('a').clone();
$(this).nextAll('.mobile-link').first().append(myLink);
});
Demo fiddle
Append method can take a function as argument, and here it is appending to the each .mobile-link first <a> from his previous .course div
$(".mobile-link").append(function(){
return $(this).prevAll('.course:first').find('a:first').clone();
});
Check the below snippet
$(".mobile-link").append(function(i) {
return $(this).prevAll('.course:first').find('a:first').clone();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="course">Accounting
</div>
<div class="start-date">1-1-2017</div>
<div class="credits">4</div>
<div class="location">Online</div>
<div class="mobile-link"></div>
<div class="course">Business
</div>
<div class="start-date">1-1-2017</div>
<div class="credits">3</div>
<div class="location">Online/Campus</div>
<div class="mobile-link"></div>
I beleive that you should use last (If I understood question correctly):
var lastDiv = $(".mobile-link").last();
$(".course a:eq(0)").clone().appendTo(lastDiv);
Here is jsfiddle: fiddle
<div id="CntWrapper_CntMain_ssm_ctl00_ctl01" class="matrix">
<div class="CollapseGroup1"></div>
<div class="row">
<div class="cell_24"> </div>
</div>
<div class="row">
<div class="cell_24">
<span class="label-passive">text</span>
</div>
</div>
<div class="CollapseGroupClose1"></div>
</div>
I'm trying to manipulate above HTML code sample. It's a simplified version the actual HTML code.
<script type="text/javascript">
$(document).ready(function() {
$('.CollapseGroup1').nextUntil('.CollapseGroupClose1',').css( "display", "none" );
});
</script>
This script hides all the div with class 'row' between the two divs called collapsegroup and collapsegroupclose.
However, I only want to hide the div elements with class 'Row' when any of these rows contain at least one span with class 'label-passive'.
<script type="text/javascript">
$(document).ready(function() {
$('.CollapseGroup1').nextUntil('.CollapseGroupClose1','div[.label-passive]').css( "display", "none" );
});
</script>
Just simply hiding any row div when there is a span with label-passive is not good enough. There can be rows with 'label-passive' span classes outside these collapsegroup divs that I don't want to hide.
I want to hide all rows between two collapsegroup tags, even when just one of these rows actually has a child span element with class 'label-passive'.
So, after reading your question once.. Twice.. Trice.. I think you want this:
(pro-tip: try to keep your questions as simple as possible, using pseudo-code if you must)
$('.label-passive').parents('._row').hide();
If this isn't completely what you wanted, leave a comment and I'll try to improve the answer.
Edit: Improved answer as OP improved his question:
Maybe this will help you further then:
$('.CollapseGroup1').each(function() {
if ($(this).find(".label-passive").length != 0)
$(this).hide();
});
You can simply try this:
$('div.row:has(.label-passive)').hide();
Try closest():
$('span.label-passive').closest('div.row').hide();
$(function() {
$('span.label-passive').closest('div.row').hide();
});

<div class="row">
<div class="cell_24">

I don't think my question is difficult but I'm just a newbie in jQuery and this forum so hope that you can help me with this problem. I just want to open seperately the content of two divs by two button with the same class name and for easier to understand I will show my code snippet first:
<div id="CNN">
<div id="article1">
<div class="content">
My content of CNN goes here
</div>
<div class="more">
My button goes here
</div>
</div>
</div>
<div id="Bloomberg">
<div id="article1">
<div class="content">
My content of bloomberg goes here
</div>
<div class="more">
My button goes here
</div>
</div>
</div>
And here is my current jQuery code which is not working:
$(document).ready(function() {
$("div.more").each(function() {
$(this).click(function() {
var target = $(this).parent().next(".content");
$(target).slideDown("slow");
});
});
});
Here I want to click more button and it will show only the content belongs to it. You are free not to follow my current code :). So that's all of my question, hope you all can help me to improve my programming skill and thanks you so much in advanced!
$(document).ready(function() {
$("div.more").click(function(){
$(this).parent().find("div.content").slideDown("slow");
});
});
Should do the trick
Try this:
$(document).ready(function() {
$("div.more").click(function() {
var target = $(this).parent().find(".content");
target.slideDown("slow");
});
});
Example Fiddle
Try this:
$("div.more").click(function() {
$(this).prev().slideDown("slow");
});
<script type="text/javascript">
jQuery(document).ready(function() {
jQuery(".content").hide();
jQuery(".link").click(function()
{
jQuery("div.content").slideToggle(500);
});;
});
</script>
How to expand only the div which is linked to the specific link?
Edit:
Its done like this
<div class="comment">
<div class="bar">
<a class="link">#</a>
</div>
</div>
<div class="content">
<div class="comment">
<div class="bar">
<a class="link">#</a>
</div>
</div>
</div>
EDIT 2:
You changed your HTML. Now do this:
jQuery(this).closest('div.comment').next('div.content').slideToggle(500);
But wait! Now you have 2 different div.link elements in different relation to .content elements. Is this your actual HTML markup?
You could also do this:
jQuery(this).closest('div.content').slideToggle(500);
Please provide your actual HTML.
EDIT:
Based on updated question, do this:
jQuery(this).parents('div.blaat1').eq(1).next().slideToggle(500);
How to expand only the div which is linked to the specific link?
How are they linked?
If the div is a descendant, do this:
jQuery(this).find('div.content').slideToggle(500);
If the div is a an ancestor, do this:
jQuery(this).closest('div.content').slideToggle(500);
If the div is the next sibling, do this:
jQuery(this).next().slideToggle(500);
If the div is the previous sibling, do this:
jQuery(this).prev().slideToggle(500);
Without seeing your HTML structure, we can only guess at the solution.
For this HTML:
<div class="blaat1">
<div class="blaat1">
<a class="link">#</a>
</div>
<div class="blaat2">
<a class="link">#</a>
</div
</div>
<div class="content">
<div class="otherdivs">
<div class="blaat1_div"><p>Hi – I'm blaat 1</p></div>
<div class="blaat2_div"><p>Hi – I'm blaat 2</p></div>
</div>
</div>
Use this JS:
<script type="text/javascript">
$(document).ready(function() {
$(".content").hide();
$(".link").click(function() {
var blaat = $(this).parent().attr("class");
$(blaat+"_div").slideToggle(500);
});;
});
</script>
I haven't tested that, but it should work.
Try this:
$(".link").click(function(){
$(this).parents('div.content').slideToggle(500);
});;
