javascript - AngularJS - Passing nested variable with ng-click -

this answer helped me understand how bound variable via ng-click: how can pass bound variable ng-click function?

however, if variable needs passed nested variable?

for example:

the nested variable: {{item['id']['attributes']['im:id']}}

how called inside of ng-click?

<a ng-click="open('item['id']['attributes']['im:id']')">

definitely not work because of multliple use of single quote.

thanks!

__ edit ___

attached jsfiddle of trying achieve: http://jsfiddle.net/runae/4/

basically in $scope.test, value trying pass within ng-click contoller {{ item['id']['attributes']['im:id']}}

for reference, believe correct solution question asked above: here jsfiddle future reference: http://jsfiddle.net/runae/6/

ng-click="open(item.id.attributes['im:id'])"

the non-proper variable placed within enclosing brackets.

hope future searchers.
