jquery - How to access element in JSON and Javascript -

how access javascript , jquery?

"condition" : [{"conditionid":["3000"],"conditiondisplayname":["used"]}] 

(this excerpt)

i tried using item.condition , got:
[{"conditionid":["3000"],"conditiondisplayname":["used"]}] result.

how conditiondisplayname?

i've tried using : item.condition.conditiondisplayname doesn't work nor item.condition[1]

you're there condition array 1 object need use array notation access it:

var displayname = item.condition[0].conditiondisplayname; 

if there more 1 object in array, can use loop:

for(var i=0; i<item.condition.length; i++) {     console.log( item.condition[i].conditiondisplayname ); }
