javascript - "Cross origin requests are only supported for HTTP." error when loading a local file

Just to be explicit - Yes, the error is saying you cannot
point your browser directly at
file://some/path/some.html

Here
are some options to quickly spin up a local web server to let your browser render local
files

Python
2

If you have Python
installed...

Change directory
into the folder where your file some.html or file(s) exist
using the command cd
/path/to/your/folder

readability="-1">

Start up a Python web server using the command
python -m
SimpleHTTPServer

This
will start a web server to host your entire directory listing at
http://localhost:8000

start="3">

You can use a custom port python -m
SimpleHTTPServer 9000 giving you link:
http://localhost:9000

This
approach is built in to any Python
installation.

Python
3

Do the same steps, but use the following
command instead python3 -m
http.server

Node.js

Alternatively,
if you demand a more responsive setup and already use
nodejs...

Install
http-server by typing npm install -g
http-server

readability="0">

Change into your working directory, where
yoursome.html lives

readability="-1">

Start your http server by issuing http-server
-c-1

This
spins up a Node.js httpd which serves the files in your directory as static files
accessible from
http://localhost:8080

Ruby

If
your preferred language is Ruby ... the Ruby Gods say this works as
well:

ruby -run -e httpd . -p
            8080

PHP

Of
course PHP also has its
solution.

php -S
            localhost:8000
