Loading an img object with a src in javascript

I want to add a thumbnail picture to a book's details, derived from the google books api, on the webpage. The code below will place the source code (api) for the appropriate book, first into the text field bookCover and then into the var copyPic, and then it should be copied into imgDisp, but it doesn’t. I can see that bookCover holds the right text, and have checked that copyPic holds the correct content.
<img id="imgDisp" src="http://books.google.com/books/content?
id=YIx0ngEACAAJ&printsec=frontcover&img=1&zoom=5&source=gbs_api" width="85" height="110"" />
$.getJSON(googleAPI, function(response) {
$("#title").html(response.items[0].volumeInfo.title);
$("#subtitle").html(response.items[0].volumeInfo.subtitle);
$("#author").html(response.items[0].volumeInfo.authors[0]);
$("#description").html(response.items[0].volumeInfo.description);
$("#version").html(response.items[0].volumeInfo.contentVersion);
$("#modeR").html(response.items[0].volumeInfo.readingModes.text);
$("#bookCover").html(response.items[0].volumeInfo.imageLinks.thumbnail);
var copyPic = document.getElementById('bookCover').innerHTML;
document.getElementById("imgDisp").src=copyPic;
Does anyone know why not? Or can I put the api details directly into imgDisp (can’t find such code syntax anywhere on the net)? Everything else is working fine. If I put a src in directly, then it works e.g.
document.getElementById("imgDisp").src = “http://.....api”
but not with a variable.

Without more info - eg, I can't see where the getJSON() function ends or what the URL's are, I can't see what the issue may be (except, perhaps, as in my last comment).
I idea seems ok, as I can replicate it (in a cut-down version of course):
function copyImageSource() {
let d = document.getElementById("bookCover").innerHTML;
document.getElementById("imgDisp").src = d;
}
<button onclick="copyImageSource();">Get image</button>
<div id="bookCover">https://duckduckgo.com/assets/icons/meta/DDG-icon_256x256.png</div>
<img id="imgDisp" src="">
I assume that this is the sort of thing you are trying to achieve?
(javascript -> jquery:
let copyPic = $("#bookCover").html();
$("#imgDisp").attr("src", copyPic);
)
Version using jquery:
function copyImageSource() {
let d = $("#bookCover");
d.html("http://books.google.com/books/content?id=YIx0ngEACAAJ&printsec=frontcover&img=1&zoom=5&source=gbs_api");
let dCopy = d.html().replace(/&/g, "&");
$("#imgDisp").attr("src", dCopy);
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button onclick="copyImageSource();">Get image</button>
<div id="bookCover"></div>
<img id="imgDisp" src="https://www.picsearch.com/images/logo.png"/>

If you have jQuery you can easily do the following:
let source = 'https://img.com/image.png';
//to get the image object that has the above just do this:
let img = $('img[src="' + source + '"]');

image from ajax request loads in codepen but not local environment

I'm trying to use a weather api for a basic website and I'd like to use the icons too. The request works in both environments, but in my local environment I get an error for the icon
GET file://cdn.apixu.com/weather/64x64/night/116.png net::ERR_FILE_NOT_FOUND
I thought it was related to https but probably not since it's only the image that won't load.
const key = 'b7e1e81e6228412cbfe203819180104';
const url = `https://api.apixu.com/v1/current.json?key=${key}&q=auto:ip`
const main = document.getElementById('main');
$.getJSON( url, function(json) {
const loc = json.location;
const cur = json.current;
const condition = {text: cur.condition.text, icon: cur.condition.icon}
main.innerHTML = `<img src = ${condition.icon}><div>${condition.text}</div>`
}
so ${cur.condition.text} will display "partly cloudy" but the icon does not display. Any advice?
update: seems to be working fine with live-server.

It may be because the Cross-Origin Request Policy (CORS) may not allow it. Please make sure that you are allowed to access those resources.
https://enable-cors.org/ to read up more about CORS.
Secondly,
<img src = ${condition.icon}>
should be
<img src="${condition.icon}">
You are forgetting the quotation marks.
https://www.w3schools.com/tags/tag_img.asp - Read more on image tags.
Additionally use the code below:
Also add http: to image src like <img src=http:${condition.icon}>.
const key = 'b7e1e81e6228412cbfe203819180104';
const url = `https://api.apixu.com/v1/current.json?key=${key}&q=auto:ip`
const main = document.getElementById('main');
$.getJSON(url, function(json) {
const loc = json.location;
const cur = json.current;
const condition = {
text: cur.condition.text,
icon: cur.condition.icon
}
main.innerHTML = `<img src="http:${condition.icon}"><div>${condition.text}</div>`
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="main"></div>

As icon return in JSON as protocol-relative URL (without the scheme) //url.
Locally it will use the file:// protocol and that assumes the resource you’re referring to is on the local machine, But it's not.
To avoid this issue locally add http: or https:to image src like <img src=http:${condition.icon}>.
const key = 'b7e1e81e6228412cbfe203819180104';
const url = `https://api.apixu.com/v1/current.json?key=${key}&q=auto:ip`
const main = document.getElementById('main');
$.getJSON(url, function(json) {
const loc = json.location;
const cur = json.current;
const condition = {
text: cur.condition.text,
icon: cur.condition.icon
}
main.innerHTML = `<img src =http:${condition.icon}><div>${condition.text}</div>`
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="main"></div>

Embed dynamically updated blog RSS Feed to Website

I have a website on one domain, and a blog hosted on blogspot. at the bottom of the homepage on my website, I want to embed a link to the latest post on my blogspot along with the respective article image and title. I have a function that used to work but since i have moved to blogspot, the RSS url is different from what i previously used, thus the function will not work as expected anymore. How can I work this function around the blogspot rss embed link ?? thanks
blogspot rss2.0 embed link
RSS 2.0: http://blogname.blogspot.com/feeds/posts/default?alt=rss
existing function:
<script src="js/jquery.min.js" type="text/javascript"></script>
<script>
function getRSS(link, number) {
$.ajax(link, {
accepts:{
xml:"application/rss+xml"
},
dataType:"xml",
success:function(data) {
var blogItemArray = $(data).find("item");
var blogItemOne = $(blogItemArray).get(0);
var blogTitleOne = $(blogItemOne).find("title").text();
var blogLinkOne = $(blogItemOne).find("link").text();
var blogDescOne = $(blogItemOne).find("description").text();
var blogImgOne = $(blogDescOne).find("img.hs-featured-image").get();
var blogImgSrcOne = $(blogImgOne).attr("src");
$("#blog-feed-link-" + number).attr("href", blogLinkOne);
$(".vertAlignerImg" + number).append( $('<img class="blog-img-link-'+ number +'" />' ));
$(".blog-img-link-" + number).attr("src", blogImgSrcOne);
$(".vertAligner" + number).append( $('<h2 />', {text: blogTitleOne}) );
}
});
}
$(document).ready(function() {
getRSS('rsslink', "One");
getRSS('rsslink', "Two");
});
</script>
'rsslink' used to be a url that ended in /rss.xml. now it looks like the link above. thanks!

Passing image data to another page

I'm trying to access a camera and a photo album on a mobile device and get the chosen image. I did that with the code below. My problem is, it generates image data, and I have to transfer that to another page, but because of the size of the generated string, I can't use URL parameters. It shows me the error: [404] Request-URI Too long. How can I pass the information to the other page?
Here is the code: http://jsfiddle.net/8u426/
The JS:
<script>
oFReader = new FileReader();
oFReader.onload = function (oFREvent) {
document.getElementById("fotoImg").src = oFREvent.target.result;
document.getElementById("fotoImg").style.visibility = "visible";
var screenHeight = screen.availHeight;
screenHeight = screenHeight - 220;
document.getElementById("fotoImg").style.height = screenHeight;
document.getElementById("stringImg").innerText = "Data Image: " + oFREvent.target.result;
};
$(function() {
$("input:file").change(function (){
var input = document.querySelector('input[type=file]');
var oFile = input.files[0];
oFReader.readAsDataURL(oFile);
});
});
</script>
Update:
The problem is: if I try to open a new page passing the Data Image string as a parameter in the URL (with "?"). The new page will show the 404 error that I mentioned, because the string is too long.

Try changing your form to
<form id="form1" method="POST" action="[Page2 URL]">
<input id="filePic" type="file" name="image" accept="image/*" capture />
</form>
where [Page2 URL] is the URL for page to receive the image uploaded.
And JavaScript to
oFReader = new FileReader();
oFReader.onload = function (oFREvent) {
var screenHeight = screen.availHeight;
screenHeight = screenHeight - 220;
var img = $('#fotoImg');
img.attr('src', oFREvent.target.result);
img.css( { height : screenHeight, visibility: 'visible' });
$("#stringImg").text( "Data Image: " + oFREvent.target.result);
$('#form1').submit();
};
$(function() {
$("input:file").change(function (){
var oFile = this.files[0];
oFReader.readAsDataURL(oFile);
});
});

I couldn't make work with php (considering that I didn't want to work with php) and html forms (methods get and post)... So I used the jQuery library called "jQuery Storage".
It was easy, on the page that I select the image you shoud use:
$.sessionStorage([key],[value]);
So, was like that:
$.sessionStorage('chosenImg', document.getElementById("photoImg").src);
And in the new page, to get the value, just add in the code:
$.sessionStorage('chosenImg');
Of course, I had to download de .js library from the website and add the line below on both html pages:
<script src="jquery.storage.js"></script>
The only inconvenient it is a little heavy for mobile, but was the only way I found...
That is it! Thanks everyone!

Get source of image

I have a next string like:
<img src="../uplolad/commission/ranks/avatar.jpg' . $row[$c_name] .'" width="50" height="50"/>
How can i get a image file name in javascript? I know only PHP regexes. Extention of a file can be different.
The result must be: avatar.jpg

Regex is not ideal for this. JavaScript can traverse the HTML as distinct objects more readily than as a long string. If you can identify the picture by anything, say by adding an ID to it, or an ID to a parent with that as the only image, you'll be able to access the image from script:
var myImage = document.getElementById('imgAvatar'); // or whatever means of access
var src = myImage.src; // will contain the full path
if(src.indexOf('/') >= 0) {
src = src.substring(src.lastIndexOf('/')+1);
}
alert(src);
And if you want to edit, you can do that just as well
myImage.src = src.replace('.jpg', '.gif');

Fetch it following coding which can help what you want to get.
<script type="text/javascript">
function getImageName(imagePath) {
var objImage = new RegExp(/([^\/\\]+)$/);
var getImgName = objImage.exec(imagePath);
if (getImgName == null) {
return null;
}
else {
return getImgName[0];
}
}
</script>
<script>
var mystring = getImageName("http://www.mypapge.mm/myimage.png")
alert(mystring)
</script>

Here's a shorter variation of David Hedlund's answer that does use regex:
var myImage = document.getElementById('imgAvatar'); // or whatever means of access
alert(myImage.src.replace( /^.+\// , '' ));
