I have this part of HTML:
<div class="container">
<div class="row">
<div class="col-sm-4">
<div class="card">
<div class="card-body">
<h4 class="card-title">{title}</h4>
<p class="card-text">{content}</p>
Read...
</div>
</div>
</div>
</div>
</div>
and I have ajax request which calls after page loading:
<script>
$(window).on('load', function () {
loadArticles();
});
function loadArticles() {
$.ajax({
dataType: "json",
url: "/articles", success: function (result) {
}
});
}
</script>
I need to create list of cards(<div class="card">) with data from response. For example, I get 5 articles in response. I need to create 5 card divs and fill its data from the response. How can I do it?
Loop over the objects you get back from the ajax call and use the jQuery .append() function to add them to the dom.
First, you need to add an identifying class (or id) to the parent div in your HTML and remove the card HTML:
<div class="container">
<div class="row">
<div class="col-sm-4 cards-wrapper"></div>
</div>
</div>
Then in your loadArticles function loop over your ajax response and append to that jQuery selected we just defined - '.cards-wrapper':
function loadArticles() {
$.ajax({
dataType: "json",
url: "/articles",
}).done(function(data) {
const cards = data.body.cards; // Or however you need to traverse the response object
cards.forEach(function(card) {
$('.cards-wrapper').append('<div class="card"><div class="card-body"><h4 class="card-title">' + card.title + '</h4><p class="card-text">' + card.content + '</p>Read...</div></div>');
})
});
}
Ideally you should extract out that append code into its own function for readability, etc.
You can do it by simply using html template
HTML
First you need to add card-container id to the HTMl tag in which we will inject HTMl using ajax
<div class="container">
<div class="row">
<div class="col-sm-4" id="card-container">
</div>
</div>
</div>
Javascript
<script>
$(window).on('load', function () {
loadArticles();
});
function loadArticles() {
$.ajax({
dataType: "json",
url: "/articles", success: function (result) {
//Get template html using ajax and append it with **card-container**
var cardTemplate = $("#cardTemplate").html();
result.forEach(function (card) {
$('#card-container').append(cardTemplate.replace("{title}",
card.title).replace("{content}", card.content));
})
}
});
}
</script>
HTML Template
Assign id cardTemplate to html template
<template id="cardTemplate">
<div class="card">
<div class="card-body">
<h4 class="card-title">{title}</h4>
<p class="card-text">{content}</p>
Read...
</div>
</div>
</template>
I have also implemented on my end so it will surely gonna work !!!
After the article is successfully added, the modal showing the message should appear, but I'm just getting errors. So far this is my code:
Modal:
<div id="myModal" class="modal fade">
<div class="modal-dialog modal-confirm">
<div class="modal-content">
<div class="modal-header">
<div class="icon-box">
<i class="material-icons"></i>
</div>
<h4 class="modal-title">Awesome!</h4>
</div>
<div class="modal-body">
<p class="text-center">Your booking has been confirmed. Check your email for detials.</p>
</div>
<div class="modal-footer">
<button class="btn btn-success btn-block" data-dismiss="modal">OK</button>
</div>
</div>
</div>
</div>
Ajax:
<script type="text/javascript">
$('#form').on('submit', function (e) {
e.preventDefault();
var f = CKEDITOR.instances.text.getData();
var text = String(f);
var n=text.length;
var title = $('#title').val();
var docu_id = $('#docu_id').val();
var hidden_snippet = $('#hidden_snippet').val();
if (n!=0) {
$.ajax({
type: 'POST',
url: '/knowmore/index.php/ask_controller/book_add',
data: {text:text,title: title,hidden_snippet: hidden_snippet,docu_id:docu_id},
success: function (data)
{
$("#myModal").modal('show')
location.replace('/knowmore/index.php/index_controller/documentation/'+docu_id+'');
}
});
} else { alert('Enter contents of the Article!'); }
});
</script>
I used $("#myModal").modal('show') to show it but all I'm getting is an error saying modal is not a function.
If you all you need is to open a bootstrap modal, then just use
$('#myModal').modal();
It's because jQuery doesn't know any function named modal by default. If you want to show the modal you can just use show() function.
Change following
success: function (data) {
$("#myModal").modal('show')
location.replace('/knowmore/index.php/index_controller/documentation/' + docu_id + '');
}
into
success: function (data) {
$("#myModal").show();
location.replace('/knowmore/index.php/index_controller/documentation/' + docu_id + '');
}
Write down the following code.
success: function(msg)
{
$("#myModel").modal("show");
}

Description
I have a view with a list of "articles" with a "read more" button on each "article" in the list. When I click on the read more button a modal opens up with a partial view with the jquery comments in it. However, when I search for the pinged users (using the # sign), the list of users don't show by the textarea, but instead higher up in the modal (far from the textarea).
Below is an image, then below that is my code. You will see at the bottom of the image I have put the '#' sign and the list of users is displayed on the top, it should be by the textarea. It also seems that when I click on the articles lower in the list, the higher the list of users display when I push the '#' sign:

At the bottom of the partial view is this div where it is populated:

<div class="col-md-12" id="articlecomments-container">
</div>
</div>
EDIT
After spending quite some time running through the jquery-comments.js file, I found that displaying of the pinged users its happening here:
// CUSTOM CODE
// ========================================================================================================================================================================================
// Adjust vertical position
var top = parseInt(this.$el.css('top')) + self.options.scrollContainer.scrollTop();
this.$el.css('top', top);
This seems to be taking the css('top') of View, which causes the problem on the pinging of the users on the partialview.
The issue takes place rather because of your wrong bootstrap layout: you have to include all col into row, whereas in your example you use raw and col-md-12 for the same container.
After I included columns into row elements correctly everything started working the right way. In other words, just write the last section this way:
<div class="row">
<div class="col-md-12" id="articlecomments-container">
</div>
</div>
Please, take a look at an example of nesting in Bootstrap 4.
UPDATE
I've managed to reproduce the mistake thanks to your tip to draw numerous articles on the page. The issue is indeed because of scrolling, though the reason seems to be deeper in jquery.textcomplete.js in a function _fitToBottom (it takes into account the main window scroll but not of the embeded modal container). However, a faster approach I use instead of rectifying that elaborate peice of logic is exactly at the spot which you pointed to (instead of the last 2 rows you showed):
var topPoint = self.options.scrollContainer[0].offsetTop;
var scrolledWindow = self.options.scrollContainer.parents().filter(function () {
return this.scrollTop > 0;
})[0];
var spaceAvailable = $(window).height() - (topPoint - scrolledWindow.scrollTop);
var elHeight = this.$el.height();
this.$el.css('top', spaceAvailable > elHeight ? topPoint: topPoint - elHeight);
The logic is based on looking for the closest parent with scroll and then it measures whether the rest of the space is enough to render the dropdown to figure out its final position. It might slightly miss the pointer, but still works fine in spite of scrolling. I've tried it out in Chrome and Firefox. Hopefully, it will lead you to your own approach.
I have a list of resources which needs to be filtered based on the location. I have a form to filter and on click of a button, the data is filtered based on the location. I have an AJAX request and it sends a post request to /filterresources and the data matching that criteria is also fetched from the db and the resourcefilter.ejs is rendered using res.render() as given below:
resourcefilter.js:
router.post('/filterresources',function(req,res,next){
var category = req.body.category;
User.find({_id: {$ne: req.user._id}},(err,user) => {
if(err) throw err;
if(user)
{
db.findAll(Resource,{category:category})
.then(function(data){
res.render('resourcefilter',{title:"Steel Smiling",user:req.user,header:true,navbar:true,resources:data});
})
.catch(function(err){
next(err);
});
}
else {
throw(err);
}
});
});
The problem here is, as the records are fetched the UI doesn't get updated even when new ejs page is called. It still retains the previous page UI. But any console.log() statements in the new ejs page gets displayed.
resourcefilter.ejs: All console statements in this get printed without any issues but UI is not refreshed. Any help is much appreciated.

AJAX function to call to /filterresources:
function filter_resources(e) {
e.preventDefault();
var category = $('#category :selected').text();
console.log(category);
const button = this.children[this.children.length - 1];
//Form Handling with ajax
$.ajax({
url: '/filterresources',
type: 'post',
data: {category: category},
dataType: 'json',
});
function refreshDiv() {
document.getElementById("getelebyid").innerHTML = "Some <strong>HTML</strong> <em>string</em>" ;
}
}
Your ejs, js and html code are correct, the problem is that your AJAX function does not refresh the page's content, it only retrieves the content. There are 2 solutions: Either, in the EJS, change from "render" to "send" and then in the AJAX callback use the value returned as innerHTML for some element, or do a form submit, and not a jquery post. The form submit will cause a page reload.
If you don't have any errors from your server you can do a workaround with the front end:
$.ajax({
url: '/filterresources',
type: 'post',
data: {category: category},
dataType: 'json',
}).then(() => location.reload());
That will refresh your page when the request finishes.
location.reload() didn't work in this context because the filtered data needs to be passed on to the page. Hence, instead of using res.render(), i used res.send as suggested. Please find the below code:
filterresources.js
router.post('/filterresources',function(req,res,next){
var category = req.body.category;
User.find({_id: {$ne: req.user._id}},(err,user) => {
if(err) throw err;
if(user)
{
var user = req.user._id;
console.log(user);
db.findAll(Resource,{category:category})
.then(function(data){
res.send({msg: data, success: true,user: user });
})
.catch(function(err){
next(err);
});
}
else {
throw(err);
}
});
});
AJAX function:
function filter_resources(e) {
e.preventDefault();
var category = $('#category :selected').text();
console.log(category);
const button = this.children[this.children.length - 1];
//Form Handling with ajax
$.ajax({
url: '/filterresources',
type: 'post',
data: {category: category},
dataType: 'json',
success: function (response) {
if (!response.success) {
window.alert(response.msg);
}
if (response.success) {
var resource = response.msg;
var userInfo = response.user;
$('#resfilter').html(""); // reset the contents in the div
var html = `<div class="row">`;
for(var i=0;i<resource.length;i++) {
html += `<div class="col-xs-12 col-sm-6 col-md-4">
<div class="image-flip" ontouchstart="this.classList.toggle('hover');">
<div class="mainflip"> <div class="frontside"> <div class="card-custom">
<div class="card-body text-center">`;
html += `<img src="${resource[i].image}" alt="Mental Health Resource" class="img-resources">`;
html += `<div class="card-title"><b>${resource[i].name}</b></div>`;
html += `<div id="greetings" class="card-title"><textarea readonly class="resourceDesc">${resource[i].description}</textarea></div>`;
html += ``;
html += `Read More!`;
html += `<br>`;
html += `</br></div></div><br></br></div></div></div></div>`;
}
html += `</div></div></div></div>`;
}
document.querySelector('#resfilter').innerHTML = html; // add the html content to the div which was earlier reset
}
})
}
This is the part of my html code that binds to the view using a Model object.
#if (Model.Comments != null)
{
#foreach (var thread in Model.Comments.Threads)
{
<div class="comment-wrap">
<div class="comment-head">
<div class="subsciber-user" style="background: #DDEFC5">#thread.UserName.Substring(0, 2).ToUpper()</div> #thread.UserName <span>#thread.PostedDate.ToString("dd MMM yyyy")</span>

</div>
<div class="clearfix"></div>
<div class="comment-content">

</div>
#if (thread.Attachment != null)
{
<div class="comment-attachment">

<div class="ca-tiles">

}
</div>
</div>
}
</div>
}
}
My requirement is I want to bind this HTML from a jquery Ajax Success. for that, I created an Ajax call.
var val1 = $('#TaskId').val();
#*$(document).ready(function () {
$.ajax({
url: '/Task/GetTaskComments',
data: { id: val1},
dataType: "json",
success: function (comments) {
// here i neeed to bind this Html block using each loop,
// here we are getting the same response that we are getting Model.Comments in the above code as json
}
});
});
I want to append the looped Html content from ajax success inside my
<div class="bindComments">
</div>
