The midas documentation has moved. The new documentation about the midas JavaScript library is in:
 
* [https://midas.triumf.ca/docs/develop/api/javascript/ Midas JavaScript API] (overview of the libraries)
mhttpd.js contains javascript function wrappers for most MIDAS AJAX functions typically used for implementing interactive custom pages for MIDAS experiments.
* [https://midas.triumf.ca/docs/develop/api/javascript/midas/ midas.js] (the mjsonrpc_xxx JSON-RPC functions)
 
* [https://midas.triumf.ca/docs/develop/api/javascript/deprecated/#ajax-interface AJAX interface] on the Deprecated web features page (the old ODBGet(), ODBSet() etc. functions)
AJAX is a set of web development techniques used to construct interactive web applications:
* http://en.wikipedia.org/wiki/Ajax_(programming)
 
mhttpd.js is typically served by mhttpd from $MIDASSYS/resources/mhttpd.js
<pre>
<html>
<head>
...
<script src='mhttpd.js'></script>
...
</head>
...
</html>
</pre>
 
A mostly up to date copy of mhttpd.js is linked here:
* http://ladd00.triumf.ca/~daqweb/doc/midas/resources/mhttpd.js
* https://bitbucket.org/tmidas/midas/src/HEAD/resources/mhttpd.js?at=develop
 
An example for using all mhttpd.js functions is included in the MIDAS distribution under examples/javascript1:
 
* http://ladd00.triumf.ca/~daqweb/doc/midas/examples/javascript1/
* http://ladd00.triumf.ca/~daqweb/doc/midas/examples/javascript1/example.html
 
MIDAS AJAX functions can be accessed directly without using mhttpd.js wrappers (i.e. using the JSON-P script-tag method)

Helper functions:

* function XMLHttpRequestGeneric()
* function ODBExtractRecord(record, key)
* function ODBEdit(path)
* function ODBFinishInlineEdit(...)
* function ODBInlineEditKeydown(...)
* function ODBInlineEdit(...)
 
ODB access functions:

* function ODBGetRecord(path)
