javascript - populate nested ng-repeat with complex JSON -


i trying populate td multiple values in single row angularjs's ng-repeat within ng-repeat. have working until try access 3rd nested object.

object heicarchy:

object

-renewaluis

--patentui

---property.patentapplicationnumber (this want access)

originally began $.each function loop through each object came across thread nested ng-repeat, , explains more efficient , easier loop through data. issue can access properties of renewaluis, when when add object ng-repeat syntax, no data displays.

this code works:

<tr ng-repeat="transaction in $ctrl.transactionhistory">     <td>         <span ng-repeat="item in transaction.renewaluis">{{item.renewalduedate}}<br></span>      </td> </tr>

this doesn't (but need to):

<tr ng-repeat="transaction in $ctrl.transactionhistory">     <td>         <span ng-repeat="item in transaction.renewaluis.patentui">{{item.patentapplicationnumber}}<br></span>        </td> </tr>

question

why isn't td populating data patentui object?

json

}       ]    } ]

is patentui property of each renewalui ?

if it's case ng-repeat won't work properly. can use directive ng-repeat iterate on collection objects (like arrays are).

the ngrepeat directive instantiates template once per item collection.

https://docs.angularjs.org/api/ng/directive/ngrepeat

so code work be

<tr ng-repeat="transaction in $ctrl.transactionhistory">     <td>         <span ng-repeat="item in transaction.renewaluis">{{item.patentui.patentapplicationnumber}}<br></span>        </td> </tr>
