How to add an object to the datatable

puraminy

I need an extra property for the table,
how can I add it so with the table object can access my defined object ?

puraminy

I found this solution

$.fn.dataTableExt.aoGroups = [];

allan

I don't really understand I'm afraid. What are you doing with the extra static property on the dataTableExt object?

Allan

Simply I need an storage (memory) to keep some information about row groups.
in a way I can manipulate and access it via the the table object.
I don't want to call a function to recalculate it again and again.



I don't know where to declare it.
however the above code helped me.
is there anything wrong?

allan

No - that is the correct place to put extensions to DataTables! Its just an unusual question and I was curious :-).

Allan

puraminy

then please guide me.
I found it cant be accessed outside the table.
anyway

Why it is unusual?
if we have extension for functions, could we extend the table properties (fields, dynamic storages..)?
I think its a simple straightforward question and should have a simple answer.

Simply I want

oTable.myVariable

[Edit]
Sorry, I didn't understand your answer because of my poor English, I thought you say No, dont do that...
anyway finally I could access it via ...ext.myVariable

puraminy

it seems it can be accessed by

oTable.DataTable.ext.aoGroups

puraminy

When I finished my plugin I will be offer it here, I hope its not repetitious, however I didn't find such thing anywhere.

allan

Unusual just because nobody has asked that before - or at least not that I remember :-).

I don't really understand what you mean by "I found it cant be accessed outside the table." - why not? Its a global parameter.

> oTable.myVariable

Can you not just assign it directly to the object? It would help if you should me what you were looking for in a test case.

I am new to javascript and jquery,
I declared it as

$.fn.dataTableExt.aoGroups = [];

I can access it via

oTable.DataTable.ext.aoGroups
or
just found
oTable.dataTableExt.aoGroups


maybe because of misspelled name I didn't realized the later one works too.
if there is other methods I dont know

by the way I hope to receive answer to my other discussions too

allan

Those methods all sound valid :-). I still am not sure what exactly you are using it for, so I can't say if that is the best way of doing it, or not.

I try to answer as many questions as possible, but I have only a limited amount of free time. If you require urgent help, there is a priority support option available: http://datatables.net/support .

I have almost finished a plugin for row grouping but not the way you see in another plugin

I simply loop through columns and find the groups then add them to a combobox as a filter box,

this way you can view all the groups and easily multiple columns grouping is possible
I will post it soon

but forget these all.

I have another urgent need. I posted it here

I dog the web to find this again simple basic need. Why we cant filter based on input or select boxes within the cells? or any custom portion or tag.
wish I could map cells value for filtering too.

Please help me, I appreciate the time you put on members here, you are great
