Adding and deleting attributes from a javascript object

Right now I create my objects manually based on some condition... Something like this...

if (some condition)
columnModel = [{name:'order',index:'order asc', width:70, align:"center"},{name:'job',index:'job',width:300,align:'right'}]

What I want to be able to do is insert or delete from that object. Is there a way to do this? I want to be able to delete the {name:'job',index'job',width:300,align:'right'} piece if a particular condition is met and add others if other conditions are met...

Am I clear? Is this possible?

Thanks
Bryce

That's not just an object, but an array of objects. Are you talking about removing array entries? You can null them out pretty simply. If you want to manipulate the array further, here's a referecne to array methods. (The splice() method may be what you are looking for).

Thanks Bear. I brain farted on this. My coffee didn't work very well this Monday morning (it was a busy weekend with little rest). Thanks for the link. Have a great day.
