send data from ajax GET to ejs file

I am retrieving some user data with an ajax GET call, and want to display each user in a bootstrap card, so that I can filter these on the page using jQuery.
Currently, I get the data, iterate over each user and append some card elements to the <div class="card-deck"></div>:
jQuery:
$(document).ready(function() {
$.getJSON('/api/user/all')
.then(data => {
$.each(data, function (i, user) {
var userCard = '<div class="col-md-auto mb-4">' +
'<div class="card matches mx-auto" style="width: 18rem; height: 24rem;">' +
'<div class="card-body">' +
'<h5 class="card-title">' + user.username + '</h5>' +
'<p class="card-text">' + user.jobTitle + '</p>' +
'<p class="card-text">' + user.city + '</p>' +
'</div>' +
"</div>" +
"</div>";
$('#userList').append(userCard);
});
})
})
ejs:
<div class="row">
<div class="card-container align-items-left">
<div class="card-deck" id="userList">
// cards go here ...
</div>
</div>
</div>
This works, but there will be a lot of html that goes into building the cards, so I would prefer to send the entire user object (below this is user) to the .ejs file, so that I can build the card there:
<div class="row">
<div class="card-container align-items-left">
<div class="card-deck" id="userList">
<div class="col-md-auto mb-4">
<div class="card matches mx-auto" style="width: 18rem; height: 24rem;">
<div class="card-body">
<h5 class="card-title"><%=user.username%></h5>
<p class="card-text"><%=user.jobTitle%></p>
<p class="card-text"><%=user.city%></p>
</div>
</div>
</div>
</div>
</div>
</div>
Is this a job fo the jQuery data method?

You need to implement an endpoint that fetches user information and forms the template for your userList div and sends the data back as a plain html string.
This endpoint has to be called from the client via an ajax call and set the response html to the div
Server
app.get('/api/user/all',(req, res){
//get user data
const data = [{username:"john",jobTitle:"a",city:"b"},{username:"doe",jobTitle:"a",city:"b"}];
res.render('userTemplate', {users:data} ,function(err, html) {
res.send(html);
});
Client
$.ajax({
url: "/api/user/all",
cache: false,
success: function(html){
$("#userList").innerHtml(html);
}
});
userTemplate.ejs
<% for(var i=0; i < users.length; i++) { %>
<div class="col-md-auto mb-4">
<div class="card matches mx-auto" style="width: 18rem; height: 24rem;">
<div class="card-body">
<h5 class="card-title"><%= users[i].username %></h5>
<p class="card-text"><%= users[i].jobTitle %></p>
<p class="card-text"><%= users[i].city %></p>
</div>
</div>
</div>
<% } %>

EJS is server-side code.
If you want to generate your HTML server side instead of modifying the DOM client side, then replace getJSON with an ajax call (with dataType: "html") and change /api/user/all to an endpoint (which you will have to create) which gets the data and inserts it into an EJS template.

Show posts with ajax - Use of undefined constant postObj - assumed 'postObj'

I have a homepage where there is a menu with some categories and below there are the latest posts:
<ul class="Categories__Menu">
#foreach($categories->take(6) as $category)
<li class="ative">
{{$category->name}}
</li>
#endforeach
</ul>
<div class="row" id="posts">
#foreach($posts as $post)
<div class="col-12 col-sm-6 col-lg-4 col-xl-3 mb-4">
<div class="card">
<img class="card-img-top" src="{{$post->image}}" alt="Card image cap">
<h5 class="card-title">{{$post->name}}</h5>
<div class="card-footer d-flex justify-content-between align-items-center">
More
</div>
</div>
</div>
#endforeach
</div>
I want that when each category is clicked to show only the posts of that category in the homepage, but in the same homepage, not in a specific category page.
So I have this Ajax:
$(function() {
$("a[name='category']").on('click', function(){
var category_id = $(this).attr("id");
$.ajax({
url: '{{ route('category.posts',null) }}/' + category_id,
type: 'GET',
success:function(result){
$('#posts').empty();
$.each(result,function(index, postObj){
$('#posts').append("<p>"+postObj.name+"</p>");
});
console.log(result);
},
error: function(error) {
console.log(error.status)
}
});
});
});
And its working fine, but instead of show just this:
$('#posts').append("<p>"+postObj.name+"</p>");
I want to show the posts with the real html above like:
<div class="col-12 col-sm-6 col-lg-4 col-xl-3 mb-4">
<div class="card">
<img class="card-img-top" src="{{$post->image}}" alt="Card image cap">
<h5 class="card-title">{{$post->name}}</h5>
<div class="card-footer d-flex justify-content-between align-items-center">
More
</div>
</div>
</div>
So Im using like this in ajax:
$("a[name='category']").on('click', function(){
var category_id = $(this).attr("id");
alert(category_id);
$.ajax({
url: '{{ route('category.posts',null) }}/' + category_id,
type: 'GET',
success:function(result){
$('#posts').empty();
$.each(result,function(index, postObj){
//$('#posts').append("<p>"+postObj.name+"</p>");
$('#posts').append("<div class=\"col-12 col-sm-6 col-lg-4 col-xl-3 mb-4\">\n" +
" <div class=\"card box-shaddow\">\n" +
" <img class=\"card-img-top\" src=\"{{postObj.image}}\" alt=\"Card image cap\">\n" +
" <h5 class=\"card-title h6 font-weight-bold text-heading-blue\">{{postObj.name}}</h5>\n" +
" <div class=\"card-footer d-flex justify-content-between align-items-center\">\n" +
"\n" +
" More\n" +
" </div>\n" +
" </div>\n" +
" </div>");
});
console.log(result);
},
error: function(error) {
console.log(error.status)
}
});
});
But it appears an error:
Use of undefined constant postObj - assumed 'postObj'
Do you know why?
PostController:
public function WhereHasCategory(Request $request)
{
$posts = Post::whereHas('categories', function ($categories) use (&$request) {
$categories->where('id',$request->id);
})->get();
return response()->json($posts);
}
Route to the ajax part:
Route::get('posts/where/category/{id}','\PostController#WhereHasCategory')->name('category.posts');
Method to return the homepage view:
public function index(){
return view('home')
->with('categories', Category::orderBy('created_at', 'desc')->get())
->with('posts', Post::orderBy('created_at','desc')->take(8)->get());
}

Make sure you refer to variable in Blade template with $postObj, not postObj. I can see you use it without $, like postObj.image in your tag.

This isn't perfect but it should give you some help in understanding how to append to a div via jQuery. Your data was messed up, so I fixed it and made it a valid object. You may want to use things like JSLint to check your data before testing your pages - https://jsonlint.com/
var data = {
"category": {
"books": [
{"title":"Sentra", "url":"https:/goo.gl/4cPCdn", "button":"https:google.in"},

How to add divs with some classess to another div (inside each other) in html / javascript

I want to list my products from database by clicking on category in html/view.
Firstly I created it in HTML (static) just to check how this is going to look, and it looks lik this:
Here is my html:
<div class="col-md-8" style="margin-top: -15px;">
<div class="products row">
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="images/coke.png">
<p class="product-title">
Product no1
</p>
</div>
</div>
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="images/pepsi.png">
<p class="product-title">
Product no2
</p>
</div>
</div>
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="images/coffe.png">
<p class="product-title">
Product no3
</p>
</div>
</div>
</div>
</div>
And now I want to create this block dynamically:
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="images/coffe.png">
<p class="product-title">
Product no N
</p>
</div>
</div>
Here is what I've tried so far:
<script>
function onSelectGroup(Id) {
$.ajax({
method: "GET",
url: "Products/GetProductsByCategoryId",
data: { categoryId: Id }
})
.done(function (response) {
//In response I am getting my products, looping through them to create divs like in code above
for (var i = 0; i < response.length; i++) {
//<div class="col-md-3">
// <div class="article-holder">
// <img class="img-responsive" src="images/picture_not_available_400-300.png">
// <p class="product-title">
// Product no 1
// </p>
// </div>
// </div>
//Trying to append it to my .product class because it's parent of this divs above
$(".products").append('<div class="col-md-3"></div>');
$(".products).appendChild('<div class="article-holder"></div>');
}
})};
</script>
But this is not working unfortunatelly... I tried few another things, but this appendings are not working as expected :/
Thanks guys for any help
Cheers

There are many answers posted for the question which might solve the issue with the javascript code. I am posting a different approach as OP specifically requested for it in the comments.
At times, i do not like to build complex HTML markup in javascript with jQuery ( i afraid i might make typos (missing "" or ' etc..). In that case, i would like to have my action method return a view result (the HTML markup) as the response of my ajax call and i can simply update the DOM with that as needed.
public ActionResult GetProductsByCategoryId(int categoryId)
{
var p = db.Products.Where(a=>a.CategoryId==categoryId).ToList();
return PartialView("ProductList",p);
}
Now i will have a partial view called ProductList.cshtml, which is strongly typed to a list of products and i can loop through the items passed to it and render whatever markup i want.
Here is a simple example where i am rendering a div with css class col-md-3 for each item in the collection passed to it. You can update it to render whatever markup you want to render.
#model List<Product>
#foreach (var item in Model)
{
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="#item.ImageUrl">
<p class="product-title">
#item.Name
</p>
</div>
</div>
}
Now all i have to do is, call this action method, and use the response to update my DOM. Let's give an Id to the container div which we will update
<div class="col-md-8" >
<div id="product-list" class="products row">
</div>
</div>
Now when the ajax call receives a response from server, update the inner html of the DOM element with Id product-list
$.ajax({
method: "GET",
url: "#Url.Action("GetProductsByCategoryId","Products")",
data: { categoryId: 2345 }
})
.done(function(response) {
$("#product-list").html(response);
}).fail(function(a, a, e) {
alert(e);
});
Keep in mind that, now you are getting a bigger payload (the resulting HTML)
from the server compared to the JSON data. So use this approach as you feel appropriate to do so. With this approach, i can use the C# methods in my partial view (For example, to build the path to an image in a location/ use Html helper methods etc)

I you create the dom element like any string, and append it to the container
function onSelectGroup(Id) {
//In response I am getting my products, looping through them to create divs like in code above
for (var i = 0; i <10; i++) {
let item = `<div class="col-md-3">
<div class="article-holder">
<img class="img-responsive" src="images/picture_not_available_400-300.png">
<p class="product-title">
Product no ${i}
</p>
</div>
</div>`
//Trying to append it to my .product class because it's parent of this divs above
$(".products").append(item);
}
};
onSelectGroup();
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="col-md-8" style="margin-top: -15px;">
<div class="products row">
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="images/coke.png">
<p class="product-title">
Product no1
</p>
</div>
</div>
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="images/pepsi.png">
<p class="product-title">
Product no2
</p>
</div>
</div>
<div class="col-md-3">
<div class="product-holder">
<img class="img-responsive" src="images/coffe.png">
<p class="product-title">
Product no3
</p>
</div>
</div>
</div>
</div>

You can create a new element with jquery and fill it properly
for (var i = 0; i < response.length; i++) {
//<div class="col-md-3">
// <div class="article-holder">
// <img class="img-responsive" src="images/picture_not_available_400-300.png">
// <p class="product-title">
// Product no 1
// </p>
// </div>
// </div>
//Trying to append it to my .product class because it's parent of this divs above
var newelem = $('<div class="col-md-3"></div>');
var artholder = $('<div class="article-holder"></div>');
newelem.append(artholder);
artholder.append(<your-image><your article title>);
}

You was close; all you needed to do was create an element for each item in the results object. I've used test data in the example.
https://jsfiddle.net/tw0vrpyy/
var response = {
item1: {
id: "id1",
title: "title1",
img: "img_src1.jpg"
},
item2: {
id: "id2",
title: "title2",
img: "img_src2.jpg"
}
};
var product = document.getElementsByClassName('response')[0];
Object.keys(response).forEach(function(key) {
var el = '<div class="col-md-3">' +
'<div class="article-holder">' +
'<img class="img-responsive" src="'+ response[key].img +'">' +
'<p class="product-title">' +
response[key].title +
'</p>' +
'</div>' +
'</div>';
product.innerHTML += el;
});

How can I group divs and calculate values?

I have the next structure:
<div class="container">
<div class="block">
<div class="id">1</div>
<div class="date">02/21/2015</div>
<div class="value">111</div>
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/21/2015</div>
<div class="value">222</div>
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/30/2015</div>
<div class="value">333</div>
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/30/2015</div>
<div class="value">444</div>
</div>
<div class="block">
<div class="id">2</div>
<div class="date">05/17/2015</div>
<div class="value">555</div>
</div>
</div>
I need group it and calculate values, then I need print this in my page.
Steps:
Group by ID
Group by Date (in ID)
Calculate Values (in each Date)
So, the result:
<div class="container">
<div class="block">
<div class="id">1</div>
<div class="date">02/21/2015</div>
<div class="value">333</div> <!-- 111+222 -->
</div>
<div class="block">
<div class="id">1</div>
<div class="date">02/30/2015</div>
<div class="value">777</div> <!-- 333+444 -->
</div>
<div class="block">
<div class="id">2</div>
<div class="date">05/17/2015</div>
<div class="value">555</div>
</div>
</div>
P.S. Of course, I don't need in comments. :)
Can you help me with JS/jQ code?

This is one way (demo):
var $container = $('.container'),
$blocks = $container.find('.block'),
results = {},
output = '';
$blocks.each(function () {
var $this = $(this),
id = $this.find('.id').html(),
date = $this.find('.date').html(),
value = $this.find('.value').html();
results[id] = results[id] || {};
results[id][date] = results[id][date] || 0;
results[id][date] += parseInt(value);
});
$.each(results, function (id, dates) {
$.each(dates, function (date, value) {
output += '<div class="block">' +
'<div class="id">' + id + '</div>' +
'<div class="date">' + date + '</div>' +
'<div class="value">' + value + '</div>' +
'</div>';
});
});
$container.html(output);
