i have this div in my homepage.php file:
<?php foreach($posts as $post): ?>
</div class="post>
<div class="options">
<div class="option"></div>
<div class="option"></div>
<div class="option"></div>
</div>
<div class="none editanddelete">
<button type="button" class="edit">edit</button>
<button type="button" class="delete">delete</button>
</div>
<div class="imageandname">
<img src="<?php echo $post->user_image ?>">
<div class="username"><?php echo $post->username ?></div>
</div>
<div class="post_body">
<?php echo $post->post_body ?><br>
</div>
</div>
<?php endforeach; ?>
the $posts is array that is coming from database through controller and each time i publish a post, the body will add new div like above with the data needed from the $post array, now as shown above, the child div with class "editanddelete" is hidden by giving class "none" which is display:none;
now with javascript i want to make an event where when i click on the child div with class="options", it toggles the "none" class of the child div with class="editanddelete", like the following:
post = document.querySelector('.post');
options = post.querySelector('.options');
editanddelete = options.querySelector('.editanddelete');
options.addEventListener('click', () => {
editanddelete.classList.toggle('none');
})
when i execute this code, it works fine on the first post (div) that is dynamically created, but when i add another post, the event will not work on the second post div, i tried to use querySelectorAll and loop "options" classes that will be created dynamically, but it just does not work as expected and the event affects other divs, what i want is to make the event for all divs, every div on it's own
You need to work with the same .editanddelete element as .options is clicked.
JS code could be like
var options = document.querySelector('.options');
// here maybe would be for cycle over options (I can't test it now)
options.addEventListener('click', () => {
this.parentNode.querySelector('.editanddelete').classList.toggle('none');
})

how do you pass the value to anchor tag on every click using jquery?
I have this code here.
I am trying to get value every time I click the button
//My HTML
<button id="a-selectNm" data-a_name="<?php echo $row['username']; ?>" data-toggle="modal" data-target="#selectNm">SELECT nursemaid</a>
//The modal
<div class="modal" id="selectNm">
<div class="card-body">
<h4 class="card-title">
<?php echo $row['username']; ?>
</h4>
</div>
</div>
//My jQuery code
jQuery(document).on('click', 'button#a-selectNm', function() {
var a_name = jQuery(this).data('a_name');
jQuery('.modal a[href="#a_name"]').val(a_name);
});
</script>
What is my mistake? what do I have to change?
Replace
jQuery('.modal a[href="#a_name"]').val(a_name);
with
jQuery('.modal a[href="#a_name"]').text(a_name);
Scenario:
I have a bit tricky case here:
Upon cicking the button inside the first div block (I have named it as DIV Block A for readability), I want to display the channels which is inside the second DIV Block
(I have named it as DIV Block B for readability).
The id of button from DIV Block A is:
id="sub_category_dc_button_<?=$category['category_id'];?>"
Upon clicking this button, the content inside the DIV Block B should be displayed.
Attempt 1:
For this, I have followed this approach:
$(".sub_dc_channels").on("click", function(){
$($(this).attr("data-target")).show();
});
Here is my DIV Block A:
<div class="sub_cat_buttons channel" id="dc_subcategory_button_tab">
<div class="sub_dc_channels" id="sub_dc_button">
<?php foreach ($output as $category) {
<button type="button" data-toggle="collapse"
id="sub_category_dc_button_<?=$category['category_id'];?>"
class="btn btn-primary sub_digitalchannel_button"
data-target="#Category_<?= $category['category_id'];?>">
<?= $category['category_title']?>
</button>
</div>
</div>
Here is my DIV Block B:
<?php foreach ($output as $category) {?>
<div class="channel" id="Category_<?= $category['category_id'];?>">
<div id="subchannel_list_tab">
<?php foreach ($output as $category) {?>
<?php foreach ($category['channels'] as $channels) { ?>
<img src="<?= $channels['channel_logo']; ?>"
alt="<?= $channels['channel_name']; ?>"
title="<?= $channels['channel_name']; ?>"
style="width: 100px; height: 60px;" />
<?php } ?>
<?php } ?>
</div>
</div>
<?php } ?>
Attempt 2:
I have also used this approach with the same DIV Blocks but it fails too.
$('div[id^="Category_"]').click(function() {
$(".channel").hide();
$("#subchannel_list_tab").show();
});
Issue Faced:
When I clicked the button from DIV Block A then it targets the contents inside the DIV Block B but the contents inside the DIV Block B are not shown.
What am I missing here? Or am I following the wrong approach?
Suggestions are highly appreciated.
your click is going to be triggered in the div and not in the button, it is likely that this is the problem.
Here's a dummy example of what I think you're up to.
$('.showDiv').click( function () {
let div = $(this).attr('data-target');
$(`#${div}`).show();
});
#divB {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="divA">
<button class="showDiv" data-target="divB">show div</button>
</div>
<div id="divB">
info divB
</div>
You want to show dynamic data as per id of button click.You missed a target button class in selector.your issue is solved.
$(document).on("click",".sub_dc_channels .sub_digitalchannel_button",function(){
alert();
$($(this).attr("data-target")).show();
});

enter image description hereThis is my index_category.php.

The problem is it is taking data=1 only but in network it showing as data=1 data=2 data=3 so on...
How to pass all the values from div in index_category.php to script in index.php
as u can see in the image i want to filter the sub category based on category. But when i click on any of the category it is taking only first value.But when u look in the image(inspect element) it is taking all the values as data=1 data=2 so on...when i click on category i want to get their respective id's.
If I understand correctly your your outer nav is repeated, that means that your $(".outer-nav") will return an array of elements not just one. You will need to iterate over them to read their data attributes. If you are looking to get just one specific one I would recommend using JQuery(since you are using it) selector for the click detection and from there working out the .outer-nav that you need.
Sorry if I did not understand your question correctly, but you use a weird mixture of pure JS and JQuery so it is a bit stange to read the code.
as #Aurus told, it is not only one element. You should modify like this:
===== 1st method =====
.... onclick="openNav(this)">
and the function too:
function openNav(element) {
...
var id=$(element).attr("data");
.....
}
===== 2nd method =====
<div class="dialog-outer" data="<?php echo $rows['cat_id']; ?>" onclick="openNav('oid_<?php echo $rows['cat_id']; ?>')" id="oid_<?php echo $rows['cat_id']; ?>">
and the function too:
function openNav(id) {
...
var id=$("#"+id).attr("data");
.....
}
in this issue, i use booster widgets tbcollapse to make some like a inbox in message menu, unread or new message is have status 0, so when i click the panel title in collapse widgets, it will open div with id #collapse, and change the status in database to be 1 (readed), its possible??? how?
<?php $collapse = $this->beginWidget('booster.widgets.TbCollapse');
<div class="panel-group" id="accordion">
<?php for ($a = 0; $a<count($pesan); $a++){ ; ?>
<div class="panel panel-warning">
<div class="panel-heading">
<h4 class="panel-title">
<a data-toggle="collapse" data-parent="#accordion" href="#collapse<?php echo $a ;?>">
<?php echo $pesan[$a]["sender"] ;?>
</a>
</h4>
</div>
<div id="collapse<?php echo $a ;?>" class="panel-collapse collapse">
<div class="panel-body">
<?php echo $pesan[$a]["message"] ;?>
</div>
</div>
</div>
<?php }; ?>
</div>
Just use bootstrap's collapse events to trigger an ajax call, for what you want probably the best option is the shown.bs.collapse event, for example:
$('#myCollapsible').on('shown.bs.collapse', function () {
//Get the id of the message and use ajax to update the database
});
Edit #1
A little example:
First add a custom id to your widget
<?php $collapse = $this->beginWidget('booster.widgets.TbCollapse',
array('id'=>"myCollapsible")
);?>
At the end of your view add a script tag, or you can register a script with yii's CClientScript. For the sake of simplicity I will use script tags
<script>
$(function(){
$('#myCollapsible').on('shown.bs.collapse', function (e) {
var target=$(e.target);//get shown element
if(target.attr('id')===$(this).attr('id'))return;//Event is fired on page load, ignore event on main collapse
$.post('controllerUrl',{messageId:$(e.target).attr("id")},function(data){//call server to update
//do something if everything was ok or display error
});
});
});
</script>
In your controller just add a method to update the message status
public function actionUpdateMessage{
MessageModel::model()->updateByPK($_POST['messageId'],'viewed'=>'1');//update the model whose id was sent, provide some validation if needed
return;//end processing
}
Hope this helps
Edit #2
In case you need to put more metadata for the ajax call, I recommend to use data attributes in your elements, so for example you could add an Id based on your database
<div id="collapse<?php echo $a ;?>" class="panel-collapse collapse"
data-messageId="<?php echo $pesan[$a]["id"] ;?>">
<div class="panel-body">
<?php echo $pesan[$a]["message"] ;?>
</div>
</div>
And in the javascript code you can retrieve the info with data method like the following
<script>
$(function(){
$('#myCollapsible').on('shown.bs.collapse', function (e) {
var target=$(e.target);//get shown element
if(target.attr('id')===$(this).attr('id'))return;//Event is fired on page load, ignore event on main collapse
$.post('controllerUrl',{messageId:$(e.target).data("messageId")},function(data){//call server to update
//do something if everything was ok or display error
});
});
});
</script>
Edit #3
If retrieving data attributes using jquery data method doesn't work, you still can access these attributes using attr method
$.post('controllerUrl',{messageId:target.attr("data-messageId")},function(data){//call server to update
//do something if everything was ok or display error
});
If the data attributes aproach doesn't work, you can also try with hidden fields like this:
Firs, instead of setting data-messageId attribute, add inside your panel-collapse div an input hidden like the following:
<div id="collapse<?php echo $a ;?>" class="panel-collapse collapse">
<input type="hidden" value="<?php echo $pesan[$a]["id"] ;?>"/>
<div class="panel-body">
<?php echo $pesan[$a]["message"] ;?>
</div>
</div>
Then, change the following in the javascript:
$.post('controllerUrl',{messageId:target.find("input").val()},function(data){//call server to update
//do something if everything was ok or display error
});
I'm new to jQuery and am having trouble figuring out the right way to loop a set of code for a basic carousel/banner rotator. I've tried a few versions of "for" statements and .each(), but I can't get it to work on my own so I'm reaching out for help.
Here's my code so far:
$('.next-1').click(function () {
$('.featured-1').fadeOut(500,function(){
$('.featured-2').fadeIn(500,function(){
$('.featured-2').toggleClass("hide");
});
});
});
$('.next-2').click(function () {
$('.featured-2').fadeOut(500,function(){
$('.featured-3').fadeIn(500,function(){
$('.featured-3').toggleClass("hide");
});
});
});
And then a similar code block for going back within the slider:
$('.prev-2').click(function () {
$('.featured-2').fadeOut(500,function(){
$('.featured-1').fadeIn(500,function(){
$('.featured-2').toggleClass("hide");
});
});
});
$('.prev-3').click(function () {
$('.featured-3').fadeOut(500,function(){
$('.featured-2').fadeIn(500,function(){
$('.featured-3').toggleClass("hide");
});
});
});
This code does work right now, I just don't want to have to output so many unnecessary lines of code when I know I could loop it. I'd like to be able to loop until there are no more "featured-n" divs to cycle through (being able to cycle around to the beginning would be great too!)
Here's the PHP/HTML I'm using to generate each "featured-n" div block:
function home_slider_loop() {
$count = 0;
query_posts ('tag=slider');
if (have_posts()) : while (have_posts()) : the_post();
$count++;
?>
<div class="featured-post featured-<?php echo $count; if ($count>1) { echo ' hide';}?>">
<div class="featured-header">
<h1 class="featured-title"><?php the_title(); ?></h1>
<p class="author">Written by Evan Luzi</p>
</div>
<div class="image-wrap">
<?php the_post_thumbnail('full', array('class' => 'slider-image')); ?>
<div class="slider-nav">
<div class="featured-prev prev-<?php echo $count; ?>"></div>
<div class="featured-next next-<?php echo $count; ?>"></div>
</div><!--End Navigation-->
</div><!--End Image <?php echo $count; ?>-->
<div class="featured-footer">
<?php the_excerpt(); ?>
<a class="more-link" href="<?php the_permalink(); ?>" alt="<?php the_title(); ?>" >Read more</a>
</div>
</div><!--End Featured <?php echo $count; ?>-->
<?php
endwhile;
endif;
}
Here's a sample of one of the static HTML outputs (just imagine this iterated several times with the "featured-n" classes incrementing:
<div class="featured-1">
<div class="featured-header">

Thank you in advance for your help and please be kind to a n00b :)
Use something like this :
$('.nav .prev').click(function(){
activeBlock = $('.featured.active');
prevBlock = activeBlock.prev('.featured');
activeBlock.fadeOut('slow',function(){
prevBlock.fadeIn().addClass('active');
}).removeClass('active');
});
$('.nav .next').click(function(){
activeBlock = $('.featured.active');
nextBlock = activeBlock.next('.featured');
activeBlock.fadeOut('slow',function(){
nextBlock.fadeIn().addClass('active');
}).removeClass('active');
});
Html
<div class="nav">
<div class="prev"> </div>
<div class="next"> </div>
</div>
<div class="featured-post featured <?php if($count>1) echo 'hide' ?>">
<div class="featured-header">
<h1 class="featured-title"><?php the_title(); ?></h1>
<p class="author">Written by Evan Luzi</p>
</div>
<div class="image-wrap">
<?php the_post_thumbnail('full', array('class' => 'slider-image')); ?>
</div>
<!--End Image <?php echo $count; ?>-->
<div class="featured-footer">
<?php the_excerpt(); ?>
<a class="more-link" href="<?php the_permalink(); ?>" alt="<?php the_title(); ?>" >Read more</a>
</div>
</div>
You could do it this way :
$('.featured-next, .featured-prev').click(function () {
//find out if the clicked element is a prev or next element, extract the last part, will be useful later
var direction = $(this).hasClass("featured-next") ? "next" : "prev";
//select the ".featured-n" block which is the super-parent of clicked element
var $fullBlock = $(this).closest('div[class^="featured-"]'); //or add a class here to make your life easier
//fade out full block
$fullBlock.fadeOut(500, function () {
//search for the next element and show it
//note that $fullBlock.next() => $fullBlock["next"]() => $fullBlock[direction]()
$fullBlock[direction]().fadeIn(500, function () {
//toggle the class "hide" of the element next to fullBlock
$(this).toggleClass("hide");
});
});
});
Explanation:
You can join up both prev and next events together.
Then, you have to check if its a next or a prev element. Set that to a variable called direction. We'll be using this to find out if we have to use prev() or next() when we're trying to fadeIn featured-n divs.
Find the parent with the class set to featured-n (in your case its the superparent). It might be better if you give a common class to all these elements so that we can stop using 'div[class^="featured-"]' selector, which is slightly inefficient.
Fade out the superparent.
In the callback, based on the direction variable, we'll have to decide if the carousel is gonna go to prev block or next block, something like this :
if(direction === "prev")
{
$fullBlock.prev().fadeIn(//your code)
}
else
{
$fullBlock.next().fadeIn(//your code)
}
You must also know that, in an object like this :
var data = {"name" : "Blah Blah"}
To get the "Blah Blah" out, we can say
data.name
or we could say :
data["name"]
So based on this, in our situation, instead of
$fullBlock.prev()
Or we could say
$fullBlock["prev"]()
Which is what direction variable contains. So finally, we could do this to select the next/prev element based on what was clicked :
$fullBlockdirection
Show the prev/next element.
Add/remove "hide" class.
Hope this helped!
