HTML Tittle attribute showing only First Word

I using title attribute in jQuery.
createAlert: function () {
return '<img id="img" class="img pull-left" src="/Content/img/demo_16px.png" tabindex="0" style="outline: none;" title=' + demo.rawData + '></span>';
}
Here In this code, title contain dynamic data(demo.rawData Contain text = 'This is my code')
But when I hover in a browser for title it only displaying This(i.e only first word)
Can anyone tell what I am doing wrong.?

You need to surround the title in "" like so title="' + demo.rawData + '" rather than title=' + demo.rawData + ' otherwise the rendered HTML will be invalid
createAlert: function () {
return '<img id="img" class="img pull-left" src="/Content/img/demo_16px.png" tabindex="0" style="outline: none;" title="' + demo.rawData + '"></span>';
}

Here you go with one more solution using ES6 template literal
createAlert: function () {
return `<img id="img" class="img pull-left" src="/Content/img/demo_16px.png" tabindex="0" style="outline: none;" title="${demo.rawData}"></span>`;
}

jQuery can't catch the parent element

I am trying to access the parent element up to the button element to modify its css. I can access the span element via id. But when I try to go to the parent img it says undefined
Here is my html code
<button type="button" class="buttonLike">\
<img src = "../Image/thumbsUp.png" clas="test">\
<span class="postID" id=' + idPost + '>' + likesPost + '</span>\
</img>\
</button>\
and here is my jquery code that access the span element
$.each(result, function (index,data) {
var liked = data.liked;
if (liked == true) {
console.log($("#" + postId).parent("img").attr("src"));
}
});
How can i do this right.

img element is self-closing. try this:
<button type="button" class="buttonLike">\
<img src = "../Image/thumbsUp.png" clas="test">
<span class="postID" id=' + idPost + '>' + likesPost + '</span>\
</button>
and get it with jquery:
console.log($("#" + postId).parent().find("img").attr("src"));

I think you should not wrap the span inside the img. that will make more easy for you. But if you still want to. try this.
$("#postId").closest("img");

try using this
.parent().find('img').attr('src')
console.log($("#idPost").parent().find('img').attr('src'));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" class="buttonLike">
<img src = "Image/thumbsUp.png" class="test">
<span class="postID" id='idPost'>likesPost </span>
</button>

I have closed the image and made the span as sibling of parent;
In this code snippet I have provided both jquery approach and pure js approach. Hope this helps.
//jquery approach
console.log($(".postID").siblings('.test').attr("src"));
//pure js
console.log(document.getElementsByClassName("postID")[0].previousElementSibling.getAttribute('src'));
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" class="buttonLike">
<img class="test" src="http://cdn3-www.dogtime.com/assets/uploads/gallery/goldador-dog-breed-pictures/puppy-1.jpg"/>
<span class="postID" id=' + idPost + '>' + likesPost + '</span>
</button>

JQuery: Unable to get property from each img in a list of images

I'm trying to create a snippet of HTML, and iterate through each image within that snippet and apply a listener function and modify the image. However, using JQuery's .each() function is not allowing me to use functions such as .prop() to get/set image attributes. How can I apply functions such as .prop() to elements iterated over by the .each() function.
//formatImg simply returns a URL to the resource
var images = '<div class="flex-row">\
<div class="img">\
<img class="img-cover" data-src="' + formatImg(gallery.posts[0].image, 'medium') + '">\
</div>\
<div class="img">\
<img class="img-cover" data-src="' + formatImg(gallery.posts[1].image, 'medium') + '">\
</div>\
</div>';
var location = gallery.posts[0].location.address || 'No Location';
var elem = $('<div class="col-xs-6 col-md-3 tile story">\
<div class="tile-body">\
<div class="frame"></div>\
<div class="hover">\
<p class="md-type-body1">' + (gallery.caption || '') + '</p>\
<ul class="md-type-body2">\
<li>' + gallery.posts.length + (gallery.posts.length == 1 ? ' photo' : ' photos') +'</li>\
</ul>\
</div>\
' + images + '\
</div>\
<div class="tile-foot">\
<div class="hover">\
See all\
<!--<span class="mdi mdi-library-plus icon pull-right"></span>-->\
<!--<span class="mdi mdi-download icon toggle-edit toggler pull-right"></span>-->\
</div>\
<div>\
<div class="ellipses">\
<span class="md-type-body2">' + location + '</span>\
<span class="md-type-caption">' + getTimeAgo(new Date().getTime(), gallery.time_created) +'</span>\
</div>\
</div>\
</div>\
</div>'
);
elem.find('img.img-cover').each(function(){
_this = $(this);
console.log(_this.prop('data-src'));
attachOnImageLoadError(_this);
_this.prop('src',_this.prop('data-src'));
});
The console.log(_this.prop('data-src')) from within each, it returns undefined for every image.

Your problem has nothing to do with each(). Your problem is that you're trying to use prop() to handle HTML5 data attributes.
"data-src" is not an HTML property, therefore _this.prop('data-src') returns null. You would run into the same problem if you were using prop() to try to write to a data-src attribute.
Instead, to read a data attribute named data-src using jquery, use data(). So use _this.data('src').
See https://api.jquery.com/data/#data-html5 for more help.

I have created a simple script below that may help you to make it work:
var images = '<div class="flex-row">\
<div class="img">\
<img class="img-cover" data-src="img-1" />\
</div>\
<div class="img">\
<img class="img-cover" data-src="img-2">\
</div>\
</div>';
$(images).find('img.img-cover').each(function() {
alert($(this).data('src'))
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Using the .map function to create an array of image alt text inside a specific div?

I have a page I'm using to grab image alt text from a slider. Each image has a different alt text, and I'm trying to pull it into an array and then loop through it to display it.
However when I implement it, it only adds one object to the array as opposed to how ever many it may ACTUALLY have inside the div.
$(document).ready(function () {
var tn_array = $("#rightSlider img").map(function () {
return $(this).attr("alt");
});
for (var i = 0; i < tn_array.length; i++) {
alert(tn_array[i]);
$('#links').append('<a href="#" title="' + tn_array[i] + '" >' + tn_array[i] + '</a><br />');
}
});
Here is the main page that the code grabs the alt text from:
<div id="rightSlider">
<div>
<img src="images/adptvtch_s1_1.jpg" alt="Hearing Aid On A Female's Ear" width="330" height="215" />
</div>
<div>
<img src="images/adptvtch_s1_2.jpg" alt="Hands Reading Braille Book" width="330" height="215" />
</div>
<div>
<img src="images/adptvtch_s1_3.jpg" alt="Man In Wheelchair Reading" width="330" height="215" />
</div>
</div>
I've tried other things such as .each and I can't seem to pinpoint why it's only adding the first alt text and not the other ones. If you guys can help me figure it out, I'd be greatly appreciative.

You don't need additional iteration and an unnecessary array manipulation.
Try this,
var xEle = $('#links');
$("#rightSlider img").each(function() {
xEle.append('<a href="#" title="'+ $(this).attr("alt") +'" >'+ $(this).attr("alt") +'</a><br />');
});

nth-child. Create a div and populate it

I have this function that appends a div (Base-Shirt) to a div (Button)
<div class="Button"><div class="Base-Shirt"></div></div>
I then want the images to populate the (Base-Shirt) div. When I run the script the images are placed after the "Base-Shirt" div. Do you know how I would get them into the "Base-Shirt" and not after them?
This is what is happening:
<div class="Button">
<div class="Base-Shirt"></div>
<img class="2016" src="img/swatch/2016.jpg" title="Ruby_Red" alt="Main, Pique">
<img class="2017" src="img/swatch/2017.jpg" title="Khaki_Tan" alt="Main, Pique">
This is what I want to happen:
<div class="Button">
<div class="Base-Shirt">
<img class="2016" src="img/swatch/2016.jpg" title="Ruby_Red" alt="Main, Pique">
<img class="2017" src="img/swatch/2017.jpg" title="Khaki_Tan" alt="Main, Pique">
</div>
Function
function parse(document){
//Product
$(document).find("Item").each(function(){
$(".Button").append('<div class="' + $(this).attr('name') +'"></div>');
});
//Swatch
$(document).find("Swatch").each(function(){
$(".Button:nth-child(1)").append(
'<img class="' + $(this).attr('name') + '" alt="' + $(this).attr('alt') + '" title="' + $(this).attr('title') + '" src="img/swatch/' + $(this).attr('name') + '.jpg">'
);
});
}//function parse End
Thank you.

You could try $(".Button").children(":first") which will land you on the div-shirt element

use children and eq
$(".Button").children(":eq(0)"); //<-- this will get you the first children(start form 0)
$(".Button").children(":eq(1)"); //<-- this will get you the second children
