fetching value from object

In onBeforeRender Event, I got below object

cellCss
:
Object
$count:0
$level:1
$parent:0
id:1491549149745
max_'_Rank:224
name:"Equity Flow Derivatives"
sum_'_Revenue:345.1188078023178
sum_'_SOW:930.8477745553106

so, How to catch max_'_Rank,sum_'_Revenue andsum_'_SOW value from object

I use obj.(/_Rank/i) but it is not working

AFAICS, it won’t work due to basic addressing rules.

You can try something like this to iterate through the object and extract the needed keys/key values.
