javascript - Angular ng-repeat $index -

-

i'm creating list of items user can click go next picture.

<ol class="indicators"> <li ng-repeat="img in pics" ng-click="slideto($index)"></li> </ol>

this code works problem doesnt fill in $index in ngclick directive. resulting html:

<li ng-repeat="img in pics" ng-click="slideto($index)" class="ng-scope"></li>

if put $index in between {{ }}, work, error in console.

resulting html:

<li ng-repeat="img in pics" ng-click="slideto(0)" class="ng-scope"></li>

error:

error: [$parse:syntax] http://errors.angularjs.org/1.3.15/$parse/syntax?p0=%7b&p1=invalid%20key&p2=10&p3=slideto(%7b%7bnanndex%7d%7d)&p4=%7b%index%7d%7d

i've seen examples of dont use curly brackets $index used in child element , not element itself.

could tell me i'm doing wrong , when should use {{ }} when using angular expressions.

inspector not show filled in, however, if try logging parameter passed function see indeed corresponding index number item clicked on.
