modify firebug dom object with javascript

Question

The screenshot of Firebug above shows the DOM objects from a site I have loaded. Actually I am using a library (EditableGrid) to allow me editing a table called 'itemlist'.

I want to set the columns property editable to false "on the fly" with JavaScript. In the header bar of Firebug I see Window > databgrid > editableGrid > columns > 3.

Can anybody point me to the correct way on accessing and modifing the "editable" object attribute of column 3.

I tried in various combinations of

var tbl = document.getElementById('itemlist');

var col = document.getElementClassName('window.datagrid.editableGrid.columns');
col.value = "true";

but I couldn't access the property.

document.getElementById() and document.getElementClassName() select HTML elements. You want to access a DOM object. Looking at the path shown within Firebug's DOM panel it should be accessible directly via datagrid.editableGrid.columns[3].

when I enter the statement in the console window: var eg3 = document.getElementsByName('datagrid.editableGrid.columns[3]') I get a reply undefined. That is still my problem.

Don't use document.getElementsByName() or suchlike, just enter datagrid.editableGrid.columns[3] directly.

Sebastian was perfectly right. There is no need to retrieve the element via the DOM functions.

value = datagrid.editableGrid.columns[3];

Just retrieves the datastructure variable. I wasn't aware that black/bold colored objects could be set and get directly.
