$.ajax error uncaught SyntaxError: Unexpected token :

The code is in coffeescript
I am trying to read a json file using the code below (cross domain)
$.ajax
url: 'https://canttypecompanyurlhere/books.json'
dataType: 'JSONP'
jsonpCallback: 'callback'
type: 'GET'
success: (data) ->
console.log (data)
error: () ->
console.log('error')
And here's the json
{
"name": "book-1",
"author": "someone smart"
}
What am I doing wrong? I cannot get past the error "uncaught SyntaxError: Unexpected token :"
Please help

You're missing both the brackets to contain the $.ajax function parameters, as well as the braces to indicate the beginning and end of the data object, not to mention the commas at the end of each line of the object's definition. It should look like this:
$.ajax ({
url: 'https://canttypecompanyurlhere/books.json',
dataType: 'JSONP',
jsonpCallback: 'callback',
type: 'GET',
success: (data) -> {
console.log (data);
},
error: () -> {
console.log('error');
}
});

"SyntaxError: expected expression, got '<'" when I used jsonp to cross domain in laravel

I used laravel5.2 in my project;
javascript:
$.ajax({
type: 'get',
url: 'http://XX.XX.XX.XX/account/status?callback=?',
dataType : 'jsonp',
contentType: "application/json",
jsonp : "callback",
jsonpCallback: "jsonpcallback",
success: function(data){
console.log(data);
},
error: function(){
alert('500 error!')
}
});
route:
Route::get('/account/status', 'HomeController#accountStatus');
controller:
public function accountStatus(Request $request)
{
return Response::json(array('name' => 'Steve', 'state' => 'CA'))->setCallback($request->input('callback'));
}
but the response information has the whole html file, it turns out my route in route.php doesn't work,because whatever I changed the request url, it returns the same error and shows:
SyntaxError: expected expression, got '<'

Getting Steam Market Values AJAX Unexpected token :

I am trying to get the data from say: http://steamcommunity.com/market/priceoverview/?appid=730&currency=3&market_hash_name=StatTrak%E2%84%A2%20M4A1-S%20|%20Hyper%20Beast%20(Minimal%20Wear)
Which contains something like this:
{"success":true,"lowest_price":"65,84\u20ac","volume":"21","median_price":"65,19\u20ac"}
My code so far:
$.ajax({
url: "http://steamcommunity.com/market/priceoverview/?appid=730&currency=3&market_hash_name=StatTrak%E2%84%A2%20M4A1-S%20|%20Hyper%20Beast%20(Minimal%20Wear)",
type: "GET",
dataType: 'jsonp',
success: function (data) {
console.log(data);
},
});
But I am getting the error Uncaught SyntaxError: Unexpected token :

Uncaught syntax error: Unexpected token < , ajax call

<script>
(function(){
var searchURL = 'http://en.wiktionary.org/wiki/search';
$.ajax({
type: "GET",
url: searchURL,
dataType: "jsonp",
cache: false,
async:false,
success: function(responseData, textStatus, XMLHttpRequest){
iframe(responseData);
}
});
})();
</script>
I added this script to my html file and it is show the following errors, copy pasting the function in console is also showing the same errors.
Uncaught SyntaxError: Unexpected token <
Resource interpreted as Script but transferred with MIME type text/html
could anyone help me resolve this issue, I am using Chrome brower.

You can't request arbitrary pages via AJAX, and jsonp doesn't magically make that work. You need to use the Wiktionary API.
The URL is http://en.wiktionary.org/w/api.php.
$.ajax({
url: 'http://en.wiktionary.org/w/api.php',
dataType: 'jsonp', // will automatically add "?callback=jqueryXXX"
cache: true, // the API complains about the extra parameter
data: { // the parameters to add to the request
format: 'json',
action: 'query',
titles: 'test'
},
success: function(data){
console.log(data);
}
});

Calling mtgox API gives JS error: Unexpected token :

I get the following error when I try to get info from the mtgox API. In chrome I can see that using jsonp is working, and there's no cross domain errors:
$.ajax({
type: 'GET',
url: 'https://mtgox.com/api/1/BTCUSD/ticker?callback=?',
async: false,
contentType: 'application/json',
dataType: 'jsonp',
success: function(json) {
console.log('ok');
}
});
