Jquery: Running AJAX locally without a webserver
(7 answers)
Closed 6 years ago.
This is extremely simple,
In a HTML file, inside of a <script> tag, I have
$.getScript("alert.js");
It doesn't work. alert.js being a basic alert(). What am I missing? The error codes read,
[Error] Failed to load resource: Origin null is not allowed by Access-Control-Allow-Origin. (alert.js, line 0)
and
[Error] XMLHttpRequest cannot load file:///Volumes/SSD2/kaely/kaely/alert.js?_=1471148162284. Origin null is not allowed by Access-Control-Allow-Origin.
I'm confused. Any help would be greatly appreciated. Thanks.
Take a look at the answer in this post Origin null is not allowed by Access-Control-Allow-Origin
Your browser (I'm guessing Chrome?) is not allowing this to occur. You could either try testing this in another browser or setting up a local web server.

You got the CORS problem. You request a resource from other domain and the other domain by default not authorize such request. More info here

Ways to circumvent the same-origin policy

I created asp.net webApi and publish in somee.com. I type link xxxx.somee.com/api/xxxx is ok. But I call in Angularjs not run
$http.get('http://xxxxxx.somee.com/api')
.then(function(response) {
console.log(response);
});
I received error:
XMLHttpRequest cannot load xxxx.somee.com/api/xxxx. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
Please give the solutions. Thank you very much.
If your Angular website and API websites are running in a different domain or with ports this issue will happen.
To resolve this please add the following code into your webapiconfig.cs file.
var cors = new EnableCorsAttribute(http(s):// xxxx.somee.com/api/xxxx, "*", "*");
config.EnableCors(cors);

How to avoid "Request header field Authorization is not allowed by Access-Control-Allow-Headers" error running JavaScript from local drive?
So I cannot modify server headers as there is no server.
Thank you.
That is not duplicate as solution offered at 'Origin null is not allowed by Access-Control-Allow-Origin' does not work, you can read about it there.
No. You will need a server like Mongoose (very simple download and run in your root). A very easy fix.

I am getting this error in Google chrome when I use paper.js.
Even if I remove All my code from my js file, then also it gives error.
Just started with paperjs, so not getting what is wrong
Uncaught Error: NETWORK_ERR: XMLHttpRequest Exception 101
after having some small code in demo.js file one more error comes:
XMLHttpRequest cannot load file:///E:/Shruti/Remote%20Triggering/demo/js/demo.js. Cross origin requests are only supported for HTTP.
You should add --allow-file-access-from-files option to chrome if you want to work offline.

I am trying to open my JSON file such as:
jQuery.getJSON('../data/json/en/nodesData.json',
function(data){
jQuery.each(data, function(){
//do something...
})
})
this yields the following error in Chrome:
XMLHttpRequest cannot load file:///C:/URL/data/json/en/nodesData.json. Origin null is not allowed by Access-Control-Allow-Origin
what's problem? How can I retrieve my json?
You really should be running a local server like Apache or IIS to run HTML/JavaScript code so you do not run into these restrictions.
You can start the browser up with the flag --allow-file-access-from-files which removes the restriction.
For security reasons, you cannot make AJAX calls to your local file system. Some browsers allow this, but others don't. Chrome has a flag that enables this, but it's off by default.
Take a look into Same Origin Policy.
You cannot load the file because technically it is located in another domain. You need to call it like localhost/<Path>/nodesData.json.
