I’ve seen many posts over the years asking if there is a javascript equivalent to the cc++ #include command, or Java’s import command for including source files. Today I decided to whip one up using Prototype. Check out the demo here.
Here is my HTML page. The code for the include statement is embedded at the top of the page. The code using the statement is in a block at the bottom of the page.

13 new Ajax.Request(jsFile, {
14 method: 'get',
15 asynchronous : false,
16 onSuccess: function(transport) {
17 18 eval(transport.responseText);
19 },
20
21 onFailure : function() {
22 alert("Failure including file: " + jsFile);
23 }
24
25 });

37 The Prototype #include statement:

40 function include (jsFile) {
41 new Ajax.Request(jsFile, {
42 method: 'get',
43 asynchronous : false,
44 onSuccess: function(transport) {
45 // Evaluate the javascript
46 eval(transport.responseText);
47 },
48
49 onFailure : function() {
50 alert("Failure including file: " + jsFile);
51 }
52
53 });
54
55 }
56 </pre>
57 <h2>
58 The javascript file I'm including:
59 </h2>
60 <p>
61 hello.js
62 </p>
63 <pre>
64
65 sayhello = function () {
66 alert("I'm saying hello!");
67 }
68
69 </pre>
70 <h2>
71 Using the include statement:
72 </h2>
73 <pre>
74
75 include('hello.js');
76
77 sayhello();
78
79 </pre>
80 <script type="text/javascript">
81 82
83 include('hello.js');
84
85 sayhello();
86
87 88 </script>
89 </body>
90 </html>

The var command takes the function out of the global scope for some reason. Here is a demo with the non-working code.

I was looking at a C tutorial on Drexel University’s site when I saw an example for generating a sine table. I decided to try adapting this little program to JavaScript. I ended up creating a rudimentary table object to render the data in a HTML table with a caption and header. The calculations use [...]

I just got season one of Torchwood and wanted to convert the episodes to a format that my Video iPod can handle. The episodes where encoded as avi files, which quicktime can’t handle out of the box. So I went to find codecs when I stumbled on Shaun from Twenty08‘s blog post with a link [...]

A few months ago at Humaniz we were working on a user interface project for an existing ASP.NET application. As a short cut, some of our developers use PHP includes when building templates to cut down down on the amount of duplicated code during the early stages of development. The client’s developers wanted to take [...]

I wanted a larger view area for the CGI troubleshooting script. This throws the output into a text area that fills the entire browser window. #!/usr/bin/perl print “Content-type: text/htmlnn”; print “”; print “”; print “”; system (“python MyPythonScript.py 2>&1n”); print”"; print “”; exit();

On most UNIX/Linux systems I’ve used changes to /etc/hosts are real time. In OS X you most reload the hosts file. This can be done with a single command rather than rebooting your machine. sudo niload -v -m hosts . < /etc/hosts

I started working on a Python program that is hosted on GoDaddy. Much to my dismay GoDaddy doesn’t provide shell logins. I was testing the scripts on my machine, but I don’t have the mysql library installed. When I started to write the database portion of the script I wrote this PERL CGI script to [...]
