I'm using a slick slider. While I'm calling a HTML part which have slick slider using AJAX call it is not working. I've mentioned my code as below:
$(document).ready(function(){
var year = $("#year").val();
if(year == 'all'){
$.ajax({
method: 'post',
url: 'helpData.php',
data: {year:year},
success: function(data){
$("#helpData").html(data);
}
});
}
});
This is an AJAX call.
if ($(this).is(".slider3")){
$(this).slick({
dots: true,
autoplay:true,
autoplaySpeed:1500,
prevArrow: false,
nextArrow: false,
});
}
This code is for slick slider which is in another JS file which I already included.
<?php
foreach ($helpData as $hdata) {
$heData = $help->getAllImg($hdata->heid);
?>
<div class="col-md-6">
<div class="onePost">
<div class="mySlider slider3">
<?php foreach( $heData as $himg ){ ?>
<div class="bannerSlider">
<img src="<?php echo SITE_URL; ?>/img/help/<?php echo $himg->photo; ?>" class="img-responsive otherImages" />
</div>
<?php } ?>
</div>
<a href="highlightpost.php?id=<?php echo $hdata->heid; ?>">
<p class="photoCaption">
<?php echo $hdata->title; ?>
</p>
</a>
<p style="float: right;">
<i class="fas fa-share-alt"></i>
</p>
</div>
</div>
<?php } ?>
<?php } ?>
This is my helpData.php code which is called using AJAX.
Try this,
<?php
$html='';
foreach ($helpData as $hdata) {
$heData = $help->getAllImg($hdata->heid);
$html .= '<div class="col-md-6">
<div class="onePost">
<div class="mySlider slider3">';
foreach ($heData as $himg) {
$html .='<div class="bannerSlider">
<img src="'.SITE_URL.'/img/help/'.$himg->photo.'" class="img-responsive otherImages" />
</div>';
}
$html .='</div>
<a href="highlightpost.php?id='.$hdata->heid.'">
<p class="photoCaption">'.$hdata->title.'</p>
</a>
<p style="float: right;">
<i class="fas fa-share-alt"></i>
</p>
</div>
</div>';
}
echo $html;
?>

I am working on a section on my website where I need to toggle, add, and remove a class.
I have something that works really good but I was wondering if there is a simple solution to make my code better, organized, and much more readable than how it is now.
I have 4 buttons:
.info-button-left-1
.info-button-left-2
.info-button-right-1
.info-button-right-2
These buttons trigger a class to ad to the following divs:
.product-information-block-left-1
.product-information-block-left-2
.product-information-block-right-1
.product-information-block-right-2
And this is my code:
<?php
// Create id attribute allowing for custom "anchor" value.
$id = 'info-product-block-' . $block['id'];
if( !empty($block['anchor']) ) {
$id = $block['anchor'];
}
// Create class attribute allowing for custom "className" and "align" values.
$className = 'info-product-block';
if( !empty($block['className']) ) {
$className .= ' ' . $block['className'];
}
if( !empty($block['align']) ) {
$className .= ' align' . $block['align'];
}
?>

I am learning more and more every day. but I do think that there is a better way to do this.
Is there anyone who can give me an answer or a path to follow?
Thank you in advance.
To make the JS more generic you can use common class names on the elements. Then you can relate them to each other by using DOM traversal methods, such as closest() and find() to target the required element by matching indexes. Something like this:
let $productInfoBlocks = $('.product-information-block');
$('.info-button').on('click', e => {
let $el = $(e.target);
let $targetInfoBlock = $el.closest('.col').find('.product-information-block').eq($el.index()).toggleClass('active');
$productInfoBlocks.not($targetInfoBlock).removeClass('active');
});
.active { color: #C00; }
<!-- Note: I reduced the HTML to the relevant elements only -->
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="row product-information">
<div class="col col-left-product">
<div class="right">
<div class="product-image">
<div class="info-button">info-button-left-1</div>
<div class="info-button">info-button-left-2</div>
</div>
<div class="product-information-block">product-information-block-left-1</div>
<div class="product-information-block">product-information-block-left-2</div>
</div>
</div>
<div class="col col-right-product">
<div class="right">
<div class="product-image">
<div class="info-button">info-button-right-1</div>
<div class="info-button">info-button-right-2</div>
</div>
<div class="product-information-block">product-information-block-right-1</div>
<div class="product-information-block">product-information-block-right-2</div>
</div>
</div>
</div>
In similar case I used data attribute in combination with a general class name:
The general syntax for buttons:
<div class="info-button" data-place="left" data-targetId="1"></div>
The general code for target divs:
<div class="product-information-block" data-place="right" data-targetId="1">
<?php echo the_field('product_content_left'); ?>
</div>
The general code to handle all occurances:
$(".col-right-product .info-button").click(function() {
var place=$(this).data("place");
var targetId=$(this).data("targetId");
$(".product-information-block").removeClass("active");
$(".product-information-block[data-place='"+ place +"'][data-targetId='"+ targetId +"']").addClass("active");
});
I want to know if I can get all fetched ids from a PHP while loop to use them in a jQuery for a flip effect?
while ($fetch_locomotion = mysqli_fetch_assoc($result_locomotion))
{
$id = $fetch_locomotion['id'];
echo
'<a href="index.php?price='.$hash.'" style="text-decoration: none;" id="object_a_jquery">
<div id="'.$id.'" style="perspective:1000px;height:100%;width:13%;display:inline-table;">
<div class="front">
<div id="object_list_price_bg" style="background-image:url(images/bg_price_f.png);"></div>
</div>
<div class="back">
<div id="object_list_price_bg_b" style="background-image:url(images/bg_price.png);"></div>
</div>
</div>
</a>';
}
<script>$(<?php echo $id;?>).flip();</script>
You can dump them into an array and use them at a later time.
// do this before entering the loop so it isn't overwritten
$ids = [];
// Do this part inside of the while loop
$ids[] = $fetch_locomotion ['id'];
?>
/* do this part in the html section you wish to execute the javascript code */
<script>
jQuery(function ($) {
<?php foreach ($ids as $id): ?>
<?php echo "$('#". $id . "').flip();\n"; ?>
<?php endforeach; ?>
});
</script>
Edited for your exact code:
$ids = [];
while ($fetch_locomotion = mysqli_fetch_assoc($result_locomotion))
{
$ids[] = $fetch_locomotion['id'];
echo
'<a href="index.php?price='.$hash.'" style="text-decoration: none;" id="object_a_jquery">
<div id="'. $fetch_locomotion ['id'] .'" style="perspective:1000px;height:100%;width:13%;display:inline-table;">
<div class="front">
<div id="object_list_price_bg" style="background-image:url(images/bg_price_f.png);"></div>
</div>
<div class="back">
<div id="object_list_price_bg_b" style="background-image:url(images/bg_price.png);"></div>
</div>
</div>
</a>';
}
<script>
jQuery(function ($) {
<?php foreach ($ids as $id): ?>
<?php echo "$('#". $id . "').flip();\n"; ?>
<?php endforeach; ?>
});
</script>
I would suggest adding a class attribute and querying on it (instead of each ID separately).
Also, using the alternative PHP syntax would be cleaner in this context.
This becomes:
<?php while ($fetch_locomotion = mysqli_fetch_assoc($result_locomotion)): ?>
<a href="index.php?price=<?= $hash ?>" style="text-decoration: none;" id="object_a_jquery_<?= $id ?>">
<div id="<?= $fetch_locomotion['id'] ?>" class="js-flipMe" style="perspective:1000px;height:100%;width:13%;display:inline-table;">
<div class="front">
<div id="object_list_price_bg" style="background-image:url(images/bg_price_f.png);"></div>
</div>
<div class="back">
<div id="object_list_price_bg_b" style="background-image:url(images/bg_price.png);"></div>
</div>
</div>
</a>
<?php endwhile ?>
<script>
jQuery(function ($) {
$('.js-flipMe').flip();
});
</script>
Note that I also changed your <a>'s id attribute to be unique, as it should be.
I'm showing a loading bar before the content loads successfully. And after load I am displaying the content by jQuery but when i visit the page first time the loader is showing forever and the on load event isn't firing. It fires when i manually refresh the page. What's wrong with my code?
Event call code:
$(window).on('load', function(){
$("#slider-pre-loader").fadeOut("slow");
$("#video-blog-slider").fadeIn();
});
Dynamic HTML:
<div id="slider-pre-loader"></div>
<div id="video-blog-slider" style="display: none">
<div class="blog-category-items blog-page" id="blogIndex">
<div class="container">
<?php
$hpos = 0;
foreach ($categories as $category):
$categoryhref = fakeUrl::genSlugFromText($category['name']);
$listVideos = $category['videos'];
if (in_array($category['name'], $categoryDisplay)) :
?>
<div class="blog-groups">
<div class="group-heading">
<h3>
Test title
</h3>
</div>
<?php if ($category['desc'] != '') :?>
<p class="group-desc"><?php echo $category['desc'];?></p>
<?php endif;?>
<?php
$slideClass = '';
if (!$detect->isMobile() && !$detect->isTablet() ) {
$slideClass = 'blog-slider';
}
?>
<div class="<?php echo $slideClass;?> owl-lg-dot mb-none owl-theme owl-loaded" id="videoList">
<?php
$v = 0;
foreach ($listVideos as $video) :
$v++;
$itemClass = '';
if (($detect->isMobile() || $detect->isTablet()) && $v > 5) {
$itemClass = 'item-disable';
}
$videoSlug = fakeUrl::genSlugFromText($video['title']);
?>
<div class="blog-item <?php echo $itemClass;?>">
<div class="blog-image">
<a href="/blog/<?php echo $videoSlug; ?>" title="<?php echo $video['title'];?>">
</a>
</div>
<div class="caption">
<a class="blog-list-video-title" href="/blog/<?php echo $videoSlug; ?>" title="<?php echo $video['title'];?>">

<div class="blog-metas">
<small class="blog-views"><?php echo number_format($video['views']); ?> views</small>
</div>
</div>
<?php
endforeach;
?>
</div>
</div>
<?php
endif;
endforeach;
?>

jQuery placed before event call:
<script src="//code.jquery.com/jquery-1.11.3.min.js" async></script>
Don't place async attribute on your script tags unless you really need your script file to be loaded asynchronously. Right now, your 'jQuery' code is being loaded asynchronously, i.e. jQuery is most probably not loaded when you are trying to attach your event.
The only explanation for it working the second time upon manual refresh is that the browser is 'synchronously' loading the cached resource. Different browsers do this differently, so you can expect inconsistent behaviour there.
Just remove the async attribute, and you should see your event firing every time.
The $(window) selector is for selecting the viewport whereas the $(document) selector is for the entire document (that is, what's inside the <html> tag).
Try using the following:
$(document).on('load', function(){
$("#slider-pre-loader").fadeOut("slow");
$("#video-blog-slider").fadeIn();
});
I hope this working with you, I have created example you will be woking with document.ready it means JQuery see and focus on all elements in your web page, here is fiddle
Simple for test
<div id="slider-pre-loader">no</div>
<div id="video-blog-slider" style="display: none">
hi
</div>
OR your code
<div id="slider-pre-loader">no</div>
<div id="video-blog-slider" style="display: none">
<div class="blog-category-items blog-page" id="blogIndex">
<div class="container">
<?php
$hpos = 0;
foreach ($categories as $category):
$categoryhref = fakeUrl::genSlugFromText($category['name']);
$listVideos = $category['videos'];
if (in_array($category['name'], $categoryDisplay)) :
?>
<div class="blog-groups">

Javascript:
$(document).ready(function() {
$("#slider-pre-loader").fadeOut('slow');
$("#video-blog-slider").fadeIn('slow');
});
I am trying to implement an infinite scroll in my application but at the moment of reaching the end of my page, this throws the error that places.
This is the ajax code:
<script type="text/javascript">
$(window).scroll(function() {
if($(window).scrollTop() + $(window).height() >= $(document).height()) {
var last_id = $(".post-id:last").attr("id");
loadMoreData(last_id);
}
});
function loadMoreData(last_id){
$.ajax(
{
url: '/loadMoreData.php?last_id=' + last_id,
type: "get",
beforeSend: function()
{
$('.ajax-load').show();
}
})
.done(function(data)
{
$('.ajax-load').hide();
$("#post-data").append(data);
})
.fail(function(jqXHR, ajaxOptions, thrownError)
{
alert('server not responding...');
});
}
</script>
Here, is where I show the data from th DataBase:
<?php while ($post = $result -> fetch(PDO::FETCH_ASSOC)){ ?>
<div class="box-list" id="post-data">
<div class="item">
<div class="row">
<p class="post-id hidde" id="<?php echo $post['id']; ?>">
<div class="col-md-1 hidden-sm hidden-xs">
<div class="img-item"><img src="<?php echo OTRA; ?>/images/<?php echo $post['thumb']; ?>" alt=""></div>
</div>
<div class="col-md-11">
<h3 class="no-margin-top"><?php echo $post['titulo']; ?> <i class="fa fa-link color-white-mute font-1x"></i></h3>
<h5><span class="color-black"><?php echo $post['company']; ?></span> - <span class="color-white-mute"><?php echo $post['locacion']; ?></span></h5>
<p class="text-truncate "><?php echo $post['extracto']; ?></p>
<div>
<span class="color-white-mute"><?php echo fecha($post['fecha']); ?></span>
</div>
</div>
</div>
</div>
</div>
<?php } ?>
and this id the other PHP file to load more data:
<?php session_start();
require 'extras/config.php';
require 'functions.php';
comprobarSession();
$conexion = conexion($bd_config);
$qry = "SELECT * FROM publications WHERE id > '$_GET['last_id']' ORDER BY id DESC LIMIT 8";
$result = $conexion->query($qry);
print_r ($result);
$json = include('views/empleos.php');
echo json_encode($json);
on the Developer Tool of Chrome the error that show me is
jquery.js:8706 GET http://localhost/loadMoreData.php?last_id=9 404 (Not Found)
What is the name of that php file? Sounds like it is not loadMoreData.php? Perhaps it is loadData.php, and the AJAX call should be changed?
hi guys i am trying to get a button id that is in a for loop so whenever the button click the unique id that can be differentiated from other ids should be able to work. let me show you my code.
<?php foreach ($message as $key ) : ?>
<?php echo $senders_user_id=$key['senders_id']; ?>
<div class="senders_id" S_id="<?php echo $key['senders_id']; ?>" style="display: none;"></div>
<a class="list-group-item">
<div class="checkbox">
<label>
<?php echo form_open(,['id'=>'sender_user_id']); ?>
<input type="checkbox">
<button id="senders_id" class="Read" S_id="<?php echo $key['senders_id'];?>" onclick="readbyuser($senders_user_id);">Read</button>
<button id="senders_id" class="unread" S_id="<?php echo $key['senders_id'];?>" onclick="unreadbyuser($senders_user_id);">Unread</button>
</label>
</div>
<span class="glyphicon glyphicon-star-empty"></span><span class="name" style="min-width: 120px;
display: inline-block;"><?php echo $key['uname']; ?></span> <span class=""><?php echo $key['textdata']; ?></span>
<span class="text-muted" style="font-size: 11px;"></span> <span class="badge">12:10 AM</span> <span class="pull-right"><span class="glyphicon glyphicon-paperclip">
<?php echo form_close(); ?>
</span></span></a>
<?php endforeach; ?>
</div>
Now here there are three post meaning three 'senders_id' so when i click on button Read the id of that should pass but the same id is passing again and again no matter which button i click on
Here is my code
function readbyuser()
{
var senders_id=$('#senders_id').attr('S_id');
var Recievers_id=$('.Recievers_id').attr('R_id');
jQuery.ajax({
type:'post',
url:'<?php echo base_url("user/read_by_user"); ?>',
data:{id:senders_id,R_id:Recievers_id},
dataType:'json',
success:function(data)
{
console.log(data);
alert(data);
$('.unread').removeClass('unread_user');
$('.Read').addClass('read_user');
}
});
}
function unreadbyuser()
{
var senders_id=$('#senders_id').attr('S_id');
var Recievers_id=$('.Recievers_id').attr('R_id');
jQuery.ajax({
type:'post',
url:'<?php echo base_url("user/unread_by_user"); ?>',
data:{id:senders_id,R_id:Recievers_id},
dataType:'json',
success:function(data)
{
$('.Read').removeClass('read_user');
$('.unread').addClass('unread_user');
}
});
}
please tell me what i am doing wrong
<button id="senders_id" class="Read" S_id="<?php echo $key['senders_id'];?>" onclick="readbyuser($senders_user_id);">Read</button>
<button id="senders_id" class="unread" S_id="<?php echo $key['senders_id'];?>" onclick="unreadbyuser($senders_user_id);">Unread</button>
Two elements cannot have samei id. Use class name instead.
Also you can pass PHP values directly in this.
onclick="readbyuser($senders_user_id);"
as
onclick="readbyuser(<?php echo $key['senders_id'];?>);"
