• dynamically access object property using variable 10 answers

i have object data inside. first level of data 2 arrays (body, cause). each body , cause array have arrays inside of them (date, year).

totals:[{body:[             {date:[54,9,3,17]},             {year:[437,61,31,140]}]},         {cause:[             {date:[54,9,3,17]},             {year:[437,61,31,140]}]         }] 

what access body/cause array dynamically based on user has changed.

this how accessing them now.

totals[iscause].body[isyear].date[filternumber]); 

my issues body , date hard coded in there, , have access either body/cause date/year. can't seem find these property names stored as. tried set var , this

var bodycause = "body"; 

then tried pass retriever statement.

totals[iscause].bodycause[isyear].date[filternumber]);  

but fails. i'm trying figure out property name stored , if can dynamically set when need retrieve information.

your attempt correct. can easyly use var bodycause = "body"; , access content dynamically. instead of this

totals[iscause].bodycause[isyear].date[filternumber]);  

you should use this

totals[iscause][bodycause][isyear].date[filternumber]); 

should fix problem.
