Hi Dieter
There is nothing built in, but it sounds like the sort of thing a little jQuery JavaScript on the page could do very easily. You can add your own scripts to the page- see http://indicia-docs.readthedocs.org/en/ … lity.html.
Best wishes
John

Hi Dieter,

Do you have access to any funding for development work? Who are you working with?

While we are very happy to make Indicia freely available for reuse, especially where it enhances our scientific objectives, virtually all of the development work has been paid for by one organisation or another.

I am employed by the Natural Environment Research Council and we contract John to do most of the development work we require.

That sounds like a good idea. Remember, Google is your friend.
I found http://stackoverflow.com/questions/2330 … le-disable for example.

Well done.

To make it work with Indicia you have to save your javascript in to a file with the correct name in the correct directory.
See http://indicia-docs.readthedocs.org/en/ … ality.html

Once you have done that you can use the developer tools of your browser to check that your JavaScript file is loaded.

As soon as you can see your file is loaded then it will be a simple matter to debug your script. It looks like you have already identified the id attributes of the html inputs you want to select with jQuery.

Good luck.
Jim Bacon.

Hi Dieter,

To select an item with id="occAttr:5" in jQuery use $("#occAttr\\:5")
See https://learn.jquery.com/using-jquery-c … -notation/

To add a class to a control on an Indicia recording form you edit the Form Structure in the User Interface section and add lines something like

[species]
@occAttr:6|occAttrClasses=["class1", "class2"] 

if the attribute is in a grid or

[species attributes]
@occAttr:6|class="class1 class2" 

if the attributes are all added together or

[occAttr:6]
@class="class1 class2" 

if the attribute is individually positioned.

If you are only controlling two inputs it might be easier to select them individually by id with two lines of JavaScript rather than going to the trouble of adding a class in order to use one line of JavaScript.
