Recipe 6.5
shows how to use BoneScript in a browser to read GPIO pins on the Bone, but it
requires the use of an external website. This recipe shows how to move from jsfiddle to the
Bone, with a few simple steps.
Go to a working jsfiddle page (such as the one shown in
Figure 6-4
) and do the following:
1. In the lower-left panel, select all the BoneScript code and copy it to a file. In this
case, call it
jQueryDemo.js
. Save it in the
serverExample
directory.
2. From the upper-left panel, select all the HTML code and copy it to
jQueryDemo.html
in the
serverExample
directory.
3. We need to add code to inform the browser where to find the external libraries we
are using. Edit
jQueryDemo.html
and
before
your HTML, add the following lines:
<html>
<head>
<title>
BoneScript jQuery Demo
</title>
<script
src=
"static/jquery.js"
></script>
<script
src=
"static/bonescript.js"
></script>
<script
src=
"jQueryDemo.js"
></script>
</head>
<body>
4. Add the following lines
after
your HTML:
</body>
</html>
5. Open
http://192.168.7.2/serverExample/jQueryDemo.html
, and you'll now see
your values in your own web page.
NOTE
There are several useful JavaScript libraries already located in
/var/lib/cloud9/static
, and this
recipe makes use of a couple of them here.
