The following is a record of a bunch of older, deprecated (as of Dec 2017) ways of building Custom Pages.  Some of the features may still work in the newest MIDAS, but none are recommended.
The midas documentation has moved. See [https://midas.triumf.ca/docs/develop/features/monitoring_and_control/custom_pages/#older-custom-pages Older custom pages] in Custom pages: overview and [https://midas.triumf.ca/docs/develop/api/javascript/deprecated/ Deprecated web features] for the new documentation about older custom page features.
 
= Demo Custom Page =
[[File:Mhxcustom02.jpg|thumb|left|Figure 4: Demo Custom Page]]
 
This Demo uses the older <odb> tag functionality
A Demo Custom page is shown in Figure 4. The files needed to run this demo can be found in the MIDAS package in the directory ''..packages/midas/examples/custom.''
 
The HTML code for the Demo Custom page [http://ladd00.triumf.ca/~daqweb/doc/midas/doc/html/myexpt_8html_source.html myexpt.html] illustrates many of the available [[#Features available on custom pages|features]]. This example was written before the [[#MIDAS Javascript Library|MIDAS Javascript Library]], and is in HTML only (no JavaScript), with access to the ODB  via the older HTML-style [[Custom Page Features#HTML-style <odb> tabs|<odb> tags]].
 
The file [http://ladd00.triumf.ca/~daqweb/doc/midas/doc/html/xcustom_8odb_source.html xcustom.odb]
contains the ODB keys needed by this demo, including the contents of the <span style="color: purple; font-style:italic;">/Custom</span> ODB tree. This demo illustrates the use of an image file ''myexpt.gif'' with superimposed '''fills, labels''' and '''bars'''. These features are not found in the code ''myexpt.html'', but are added in the [[/Custom ODB tree]] as described in [[Custom Page Features#Superimposing labels,fills,bars onto an image|later sections]]. Loading the saved odb file  [http://ladd00.triumf.ca/~daqweb/doc/midas/doc/html/xcustom_8odb_source.html xcustom.odb] using the {{Odbedit cmd|cmd=ld}} will create all the odb keys needed for the Demo.
 
This (external) custom page is activated by adding the ODB key <span style="color: purple; font-style:italic;">/Custom/MyExpt&</span> which is a ''custom-link'' to the HTML code for the custom page
[http://ladd00.triumf.ca/~daqweb/doc/midas/doc/html/myexpt_8html_source.html myexpt.html] see [[/Custom ODB tree#Keys in the /Custom tree|Keys in the /Custom tree]]  and [http://ladd00.triumf.ca/~daqweb/doc/midas/doc/html/xcustom_8odb_source.html xcustom.odb]).
 
;Note :
Including the [[#MIDAS Javascript Library|MIDAS Javascript Library]] is strongly recommended for anyone writing new custom pages that require access to the ODB, as it includes many useful features not otherwise available.

There is some option for creating custom pages directly from ODB.  This is documented in [[Internal Custom Page]].

The midas documentation has moved. See Older custom pages in Custom pages: overview and Deprecated web features for the new documentation about older custom page features.
