How to wrap divs inside a new div?

I'm trying to wrap the two divs <div class="cm-cp-title"> and <div class="cm-cp-value"> inside a div called cm-cp-container. Actually it is working, but it merges all together, it is shown like below after I put the wrapAll();
what is that issues? im wonder how to separate each of it?
Below is the result i needed,
$(function() {
// document
'use strict';
var coupon = $('div.cm-coupon');
// Settings
coupon.each(function() {
var _coupon = $(this);
var cpValue = _coupon.attr("data-value") + "";
// Different Data type
if (_coupon.data('type') == "c1")
{
_coupon.addClass('red').css(
{
"background" : "black",
"display": "table"}
);
_coupon.append(
'<div class="cm-cp-title">' + 'black here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>'
);
}
else if (_coupon.data('type') == "c2")
{
_coupon.addClass('green').css(
{
"background" : "green",
"display": "table"}
);
_coupon.append('<div class="cm-cp-title">'+ 'green here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>');
}
else if (_coupon.data('type') == "c3")
{
_coupon.addClass('blue').css(
{
"background" :"blue",
"display": "table"}
);
_coupon.append('<div class="cm-cp-title">'+ 'blue here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>');
} else {
return false;
}
});
$('.cm-cp-title, .cm-cp-value').wrapAll("<div class='cm-cp-container'/>");
// alignment to middle
$('.cm-coupon').on('resize',function() {
$(".cm-cp-container").css('margin-top', function() {
return($('.cm-coupon').height() - $(this).height()) / 2
});
}).resize();
});//end
.cm-coupon {
width: 340px;
height: 156px;
float: left;color: #fff;
margin: 0 10px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="cm-coupon" data-type="c1" data-value="50"></div>
<div class="cm-coupon" data-type="c2" data-value="20"></div>
<div class="cm-coupon" data-type="c3" data-value="70"></div>

Working Snippet :
$(function() {
'use strict';
var coupon = $('div.cm-coupon');
var colors = new Map([["c1", "black"], ["c2", "green"], ["c3", "blue"]]);
// Settings
coupon.each(function() {
var _coupon = $(this);
var cpValue = _coupon.attr("data-value") + "";
var color = colors.get(_coupon.data('type'));
_coupon.addClass(color).css({
"background" : color,
"display": "table"
});
_coupon.append('<div class="cm-cp-title">' + color + ' here' + '</div>' + '\n' + '<div class="cm-cp-value">' + cpValue + '</div>');
$(_coupon.children()).wrapAll("<div class='cm-cp-container'/>");
});
// alignment to middle
$('.cm-coupon').on('resize',function() {
$(".cm-cp-container").css('margin-top', function() {
return($('.cm-coupon').height() - $(this).height()) / 2
});
}).resize();
});//end
.cm-coupon {
width: 340px;
height: 156px;
float: left;
color: #fff;
margin: 0 10px;
text-align: center;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="cm-coupon" data-type="c1" data-value="50"></div>
<div class="cm-coupon" data-type="c2" data-value="20"></div>
<div class="cm-coupon" data-type="c3" data-value="70"></div>
Explanation :
First
I reduced the code removing the if statements because the only difference between the blocks if/else/else was the color ("black"/"green"/"blue"). I used a Map instead, to switch the value of the color according to the type.
What I did:
var colors = new Map([["c1", "black"], ["c2", "green"], ["c3", "blue"]]);
coupon.each(function () {
var _coupon = $(this);
var color = colors.get(_coupon.data('type'));
And then use color where need to.
Second
The problem you are encoutering is because you are not wrapping all the divs into the container, but wrapping the children of the divs.
So
$('.cm-cp-title, .cm-cp-value').wrapAll("<div class='cm-cp-container'/>");
becomes
$(coupon).wrapAll("<div class='cm-cp-container'/>");
EDIT :
It seems like you want to wrap the inner elements of the coupons instead.
Then use _coupon.children() instead, like this
$(_coupon.children()).wrapAll("<div class='cm-cp-container'/>");
and move it inside the each loop.
I edited the snippet. you can check.
In fact, the way you did it in your code, it is selecting all the matching elements in the document and wrapping it altogether. That is why the last two were moving inside the black div.

Why is my webpage freezing when a filter button is clicked?

Tasked with creating a pinterest like webpage using the data from a JSON response. Each JSON object has a service_name key, which can be either manual, twitter, or instagram. I attempted to create three filter buttons so that the webpage would only display the respective data by using the on click method in jquery to pass an array to the loadData function. However, each of these buttons freeze the webpage when they are clicked.
Here is a link to the codepen: https://codepen.io/KevinM818/pen/OjMYYO
$(document).ready(function() {
var service = "";
var datePublished = "";
var manualImage = "";
var manualText = "";

var instaImage = "";
var instaUsername = "";
var instaCaption = "";
var manualItems = [];
var twitterItems = [];
var instagramItems = [];
function loadItems(array) {
//Loop through the response array to load the data into the webpage
for (var i = 0; i < array.length; i++) {
service = array[i].service_name;
manualImage = array[i].item_data.image_url;
manualText = array[i].item_data.text;
manualLinkText = array[i].item_data.link_text;

I forked your codepen with the working fiddle. The problem was actually quite simple to find.
While your for-loop runs you populate the source Array in your switch statements over and over again. So I created a second argument for your loadItems function called "is_filter". When you click on one of your filter buttons we pass true as value. If the value is set we just ignore populating the source Array in the for-loop. Hope this helps you get going in the right direction:
https://codepen.io/anon/pen/zdrgpp
This is an excerpt from one of the filters:
loadItems(manualItems, true);
And the function declaration:
function loadItems(array, is_filter = false) { ...
And here you have the inline fiddle:

Make the parent div as big as its child

I got some div in a parent div. The parent div should only be as big as its child divs.
So this is the current view
function record(id, title, description, content, dateOfCreation) { // the object
this.id = id;
this.title = title;
this.description = description;
this.content = content;
this.dateOfCreation = dateOfCreation;
this.lastEdited = dateOfCreation;
}
function init(){
var elements = []; // all records get stored here
for (var i = 0; i < 3; i++) { // create some objects
elements.push(new record(
i,
"title " + i,
"description " + i,
"content " + i,
"date " + i));
}
$(elements).each(function (index, currentRecord) { // create the div containers
var recordContainer = $("<div></div>");
recordContainer.addClass("recordContainer");
$(document.body).append(recordContainer);
recordContainer.append($("<div>" + currentRecord.title + "</div>"));
recordContainer.append($("<div>" + currentRecord.description + "</div>"));
recordContainer.append($("<div>" + currentRecord.dateOfCreation + "</div>"));
recordContainer.append($("<div>" + currentRecord.lastEdited + "</div>"));
});
}
init(); // call the routine
.recordContainer{
margin: 10px;
border: solid;
border-width: 1px;
border-radius: 2px;
border-color: #e8e9e9;
box-shadow: 1px 1px 1px #999999;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
So I want recordContainer having a relative size. When looking for some information, I tried out adding display: inline; to "recordContainer". But then doing this, the container gets weird (?). You need to try it out, then you will see what I mean.
How can I achieve my desired div?

If you need them to be narrow but remain stacked vertically, use display: table, see the snippet below.
If you need them to be narrow and go onto the same line (and possibly wrap if that no longer fits), use display: inline-block.
function record(id, title, description, content, dateOfCreation) {
this.id = id;
this.title = title;
this.description = description;
this.content = content;
this.dateOfCreation = dateOfCreation;
this.lastEdited = dateOfCreation;
}
function init() {
var elements = []; // all records get stored here
for (var i = 0; i < 3; i++) { // create some objects
elements.push(new record(i, "title " + i, "description " + i, "content " + i, "date " + i));
}
$(elements).each(function(index, currentRecord) {
var recordContainer = $("<div></div>");
recordContainer.addClass("recordContainer");
$(document.body).append(recordContainer);
recordContainer.append($("<div>" + currentRecord.title + "</div>"));
recordContainer.append($("<div>" + currentRecord.description + "</div>"));
recordContainer.append($("<div>" + currentRecord.dateOfCreation + "</div>"));
recordContainer.append($("<div>" + currentRecord.lastEdited + "</div>"));
});
}
init(); // call the routine
.recordContainer {
margin: 10px;
border: solid;
border-width: 1px;
border-radius: 2px;
border-color: #e8e9e9;
box-shadow: 1px 1px 1px #999999;
display: table;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I made some changes to improve semantics and performance as well. The problem is that the element "DIV" is by default a block element and therefore occupy the entire horizontal space.
I hope this solution helps you.
function record(id, title, description, content, dateOfCreation) { // the object
this.id = id;
this.title = title;
this.description = description;
this.content = content;
this.dateOfCreation = dateOfCreation;
this.lastEdited = dateOfCreation;
}
function init(){
var elements = []; // all records get stored here
for (var i = 0; i < 3; i++) { // create some objects
elements.push(new record(
i,
"title " + i,
"description " + i,
"content " + i,
"date " + i));
}
$(elements).each(function (index, currentRecord) { // create the div containers
var recordContainer = $("<div class='recordContainer'><div class='container container-" + index + "'></div></div>");
$(document.body).append(recordContainer);
$(".container-" + index).append("<div>" +
"<p>" + currentRecord.title + "</p>" +
"<p>" + currentRecord.description + "</p>" +
"<p>" + currentRecord.dateOfCreation + "</p>" +
"<p>" + currentRecord.lastEdited + "</p></div>");
});
}
init(); // call the routine

how to create slideshow for string 64 type image in MVC

I'm having trouble to create image slideshow. An image fetched from data base and binded into view model. it working fine. now i want to create slideshow with available images. i had tried like this.
$(function () {
function loop() {
$('.slider .inner-wrap').fadeIn("slow").css('marginLeft', 0).delay(2000)
.animate({ "marginLeft": "-200px" }, 700).delay(2000)
.animate({ "marginLeft": "-400px" }, 700).delay(2000)
.fadeOut("slow", loop);
}
loop();
});
.slider {
width: 200px;
height: 200px;
overflow: hidden;
margin: 30px auto;
background-image: url('http://www.thatssotrue.com/images/ajax_loader.gif');
background-size: 50px 50px;
background-position: center center;
background-repeat: no-repeat;
}
.slider img {
width: 200px;
height: 200px;
}
.inner-wrap {
width: 600px;
}
.item-1, .item-2, .item-3 {
display: inline-block;
vertical-align: top;
}
<tr>
<td>
<div class="slider">
<div class="inner-wrap">
<img class=" item-1" id="slides" />
</div>
</div>
</td>
</tr>
this is how i had bind my images
for (var i = 0; i < images.length; i++) {
var imgid = i;
var imagetemp = "<img id='" + imgid + "'style='margin:5px;cursor:zoom-in;width:200px;height: 150px;' onclick='getid(this)' src='" + clubimage[i] + "'>";// onclick='getid(this)'
var slider = "<img id='" + imgid + "'src='" + clubimage[i] + "'>";
$("#image").append(imagetemp);
$("#slides").append(slider);
}
My images unable to shows here. please help me. thankyou

Finally i had achieved my slideshow in knockout js. complete solutions is here.
my ajax response. I had call swapImage() method in it.
success: function (data) {
image = JSON.parse(data.imageResult);
self.bindimage(image);
for (var i = 0; i < image.length; i++) {
var imgid = i;
var imagetemp = "<img id='" + imgid + "'style='margin:5px;cursor:zoom-in;width:200px;height: 150px;' onclick='getid(this)' src='" + image[i] + "'>";
var imgslide = "<li><img class='slides' style='margin:5px' src='" +image[i] + "'/></li>";
$("#image").append(imagetemp);
}
swapImage();
if (data.imageResult == '"Invalid Connection"') {
alert("Invalid Connection");
}
i had created javascript method like this.
var i = 0;
function swapImage() {
var im = image[i];
$("#imgslide").empty();
var imgid = 'galimg' + i;
var imagesilde = "<img id='" + imgid + "'style=width:500px;height:450px;'rel='alternate' src='" + image[i] + "'/>";
$("#imgslide").fadeIn("slow", "swing");
$("#imgslide").append(imagesilde);
if (i < image.length - 1) i++; else i = 0;
setTimeout('swapImage()', 3000);
}
And bind into HTML tag like this.using selector
<div id="imgslide" />
Finally i got my requirement.

Drag/drop & delete dynamic text on HTML canvas

I've found a number of tutorials online for dragging and dropping images and shapes within an HTML canvas. But they all seem to be aimed at moving objects that are generated within the canvas when the page loads. I'm building an app that lets the user click a button on a virtual keyboard, then click on the canvas to have the corresponding number or character appear. This is my code:
<script type="text/javascript">
var mathCanvas = document.getElementById("matharea");
var ctx = mathCanvas.getContext("2d");
ctx.font="20px Arial";
var placementCallback = function(){}
mathCanvas.onselectstart = function(){return false;}
function insertOne(){placementCallback = function(x, y){ctx.fillText('1', x-6,y+6);}};
function insertTwo(){placementCallback = function(x, y){ctx.fillText('2', x-6,y+6);}};
function insertThree(){placementCallback = function(x, y){ctx.fillText('3', x-6,y+6);}};
mathCanvas.onclick = function(event){
placementCallback(event.offsetX, event.offsetY);
}
</script>
I cut out some of the insert functions to keep this shorter (the buttons in my HTML have an onclick attribute that calls these functions). I need to be able to select the characters that are placed on the screen and implement drag/drop and delete functionality, but I can't think of a way to do this for text that gets placed on the screen after the page loads (I'm fairly new to Javascript). How would I do this? I'm not expecting anyone to give me the code to do this, but if I could get a push in the right direction, that'd be great.

The problem is that canvas is immediate-mode. Whatever you tell it to put on the canvas it will put on the canvas, instantly. It will not give you the ability to modify that value in any way, shape or form.
Think of it like the difference between MS Paint (or your OS' equivalent) and Photoshop.
In PS, you can have layers which can be moved around and edited, and when you decide your image is done, you save it and it flattens all of that data.
When you make an image in MS Paint, as soon as you click or type, that thing that you put there is there, and it's not moving/being edited unless you erase it, draw over it, or draw a rectangle around a section and move that whole rectangle (including the pixels around what you're trying to edit).
Just calling fillText will paint the words on, that instant, but will not remember what it drew, where it is, what it is, how the text is different from the surrounding pixels, et cetera.
So your generalized solution is that you need to turn your text into objects, and then draw an aspect (the text-content) of those objects to the screen.
If your text changes, you can make a change in the object, and redraw it (because your object will have its X and Y coordinates stored, and will have its width value stored, using the context.measureText(textObj.text).width method/property), and when you click on the canvas, you can check the coordinates of the click, and if those coordinates intersect with your text-object's stored coordinates, then you can modify its position on the screen.
In that regard, you should look into those examples which deal with dragging objects on the canvas.
The button click should be treated as a way to CREATE one of those objects.

I know this is a lot of code ... But I didn't want to go through it .. It's PART of something I built a long time ago ... Just copy and paste into a html file ... I hope it helps with what you need:
