API problems with jQuery - javascript

I am trying to implement an API into my web page. However, for some reason none of the data is being displayed. I did a similar thing as I did with a previous API and it isn't working.
The following is my code:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script language="JavaScript" type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<script language="JavaScript" type="text/javascript">
$(function () {
var req = $.ajax({
url: "http://api.lmiforall.org.uk/api/v1/soc/search?q=computer"
});
console.log(data);
req.done(function (data) {
var wrapperDiv = $("<div />", {
"class": "wrapper"
});
var title = $("<h2 />", {
text: data[0].title
});
wrapperDiv.append(title);
$("body").append(wrapperDiv);
});
});
</script>
</body>
</html>
With the API is datatype for title, which is a job title, and I am trying to display the first title on the page. However, nothing is displayed and I get these error messages:
I honestly have no clue what is wrong with this. Any help would be much appreciated.

You log "data" outside of "done" method scope. try like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
<script language="JavaScript" type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
</head>
<body>
<script language="JavaScript" type="text/javascript">
$(function () {
var req = $.ajax({
url: "http://api.lmiforall.org.uk/api/v1/soc/search?q=computer"
});
req.done(function (data) {
console.log(data);
var wrapperDiv = $("<div />", {
"class": "wrapper"
});
var title = $("<h2 />", {
text: data[0].title
});
wrapperDiv.append(title);
$("body").append(wrapperDiv);
});
});
</script>
</body>
</html>

Why is the js and html code not running the search query?

I am trying to use Youtube's api, and run a search query to retrieve the videos found. When I run the js or the html, nothing is printing. The authentication key is correct. When I run the js file all it says is [Finished in 0.4s]. When I run the html file nothing shows up.
js file
function showResponse(response) {
var responseString = JSON.stringify(response, '', 2);
document.getElementById('response').innerHTML += responseString;
}
function onClientLoad() {
gapi.client.load('youtube', 'v3', onYouTubeApiLoad);
}
function onYouTubeApiLoad() {
gapi.client.setApiKey('hidden');
search();
}
function search() {
var request = gapi.client.youtube.search.list({
part: 'snippet',
q: 'dog'
});
request.execute(onSearchResponse);
}
function onSearchResponse(response) {
showResponse(response);
}
search html code
<!DOCTYPE html>
<html>
<head>
<script src="search.js" type="text/javascript"></script>
<script src="https://apis.google.com/js/client.js?onload=onClientLoad" type="text/javascript"></script>
</head>
<body>
<pre id="response"></pre>
</body>
By default the return value for the video link is the video ID inside the json response format.
"id": {
"kind": "youtube#video",
"videoId": "dgVKzvO5zNc"
}
you can filter the json response and create a work around like a link, here is an example:
request.execute(function(response) {
var items = response.result.items;
for(i in items){
var vidID = items[i].id.videoId;
var link = '' + "link"+[i] + '<br>';
document.getElementById('search-container').innerHTML += link;
}
});
html file
<!doctype html>
<html>
<head>
<title>Search</title>
</head>
<body>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<script src="search.js"></script>
<script src="https://apis.google.com/js/client.js?onload=googleApiClientReady"></script>
<div id="buttons"><input id="query" value='cats' type="text"/><button id="search-button" onclick="search()" >Search</button></label>

Websockets for Block.io API giving an error message

I just signed up and want to test out the Websockets API to check on an address balance. Following the API docs, I was trying to see if I could get a proof of concept working, but I can't seem to get past the "success" message. Can someone take a look at this code and let me know what I'm doing wrong?

Sorry for the late reply but you need to JSON.stringify your message. Try something like this:
https://jsfiddle.net/bxw3v8c7/
<html>
<script src="http://code.jquery.com/jquery-1.11.0.min.js"></script>
<script>
var btcs = new WebSocket('wss://n.block.io/');
btcs.onopen = function()
{
var addrToMonitor = "1SomeBTCAddress";
btcs.send( JSON.stringify( {'type':'address','network':'BTC', 'address':addrToMonitor} ) );
};
btcs.onmessage = function(onmsg)
{
var response = JSON.parse(onmsg.data);
console.log(response); //for debugging
var amount = response.data.amount_received;
$('#messages').prepend("<p>" + amount + "</p>");
}

jQuery, ajax, and php web scraper acting strangely

I'm trying to scrape a web page, but getting some weird results in my browser's console (as seen below). Here's my code:
index.html
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Icefilms Searcher</title>
<script type="text/javascript" src="jquery-2.0.3.min.js"></script>
</head>
<body>
<script type="text/javascript" src="script.js"></script>
<div id="container" style="width:1100px;position:relative;"></div>
</body>
</html>
script.js
$(document).ready(function(){
var currNum = 168000;
var maxNum = 168005;
function generateNextUrl(){
currNum++;
return currNum-1;
}
scrapeThis(generateNextUrl());
function scrapeThis(theUrl){
$.ajax({
url:
"php.php",
data:
"icefilmsURL=" + theUrl,
success:
function(response){
var movieTitle = $(response).find("#videotitle").find("span:first").text();
$("#container").append("<a href='http://www.icefilms.info/ip.php?v="+theUrl+"' target='blank'>"+movieTitle+"</a><br>");
},
complete:
function(){
if(currNum < maxNum+1){
scrapeThis(generateNextUrl());
}
},
error:
function(xhr,err){
$("#container").append("readyState: "+xhr.readyState+"\nstatus: "+xhr.status);
$("#container").append("responseText: "+xhr.responseText);
}
});
};
});
php.php
<?php
echo file_get_contents("http://www.icefilms.info/ip.php?v=".$_GET["icefilmsURL"]);
?>
The code works fine, but this is what I see in my console:
Any ideas?
You are seeing those in the console because the page you are scraping contains references to relative paths.
That is to say rather than
<img src="http://www.icefilms.info/someimage.jpg">
The code is
<img src="someimage.jpg">
Therefore, when you grab and display their HTML on your own domain the browser is trying to load the image from your domain, localhost in this case. But you do not have the image on your server.
You can use a base href in the HTML to resolve this, or you could find and replace relative path images to include the domain.
<base href="http://www.icefilms.info/">

$(document).ready function won't fire up

I'm building a project made of several jquery mobile pages, each has a navbar.
when I view each page the $(document).ready function fires up well, but when I go to the page through the navbar it won't fire up.. also in the chrome debugger I see only one html page (the one I'm currently viewing) in the source folder.
when I refresh the page the function works ok
tried to replace the "$(document).ready(function () {" with:
"$("div[data-role*='page']").live('pageshow', function(event, ui) {" as someone suggested
but that doesn't work as well.
that's the first page I load:

Reason
When jQuery Mobile loads pages after the initial one (with ajax), it will only load its BODY content, which means any js or css file initialized in HEAD (and if it is not initialized in first loaded HTML) will be disregarded. So all your custom js code will never be executed.
Solution
Move all of your js code into the first HTML file
You should create a new js file, name it whatever you want. Put all of your js code (from every page) into it. Then initialize it in the first HTML file to load.
Move your js code into the page BODY
Simply open every page and move its javascript code from HEAD to the BODY. Because of this, javascript code will be loaded into the DOM and executed when page is shown.
Final thoughts
All of this is described in more details + examples in my other answer/article: Why I have to put all the script to index.html in jquery mobile
You should also think about switching to the jQuery Mobile page events instead of document ready. Document ready usually works correctly but sometimes it will trigger before page is loaded into the DOM. That why jQM page events must be used instead. They will make sure page content is triggered only after page is safely loaded into the DOM. To find out more take a look at this answer/article: jQuery Mobile: document ready vs page events
