Am new to Angularjs, any one can help me about this infact my array is like this

array = [{"loc_name":"pronto network office","address":"3rd floor, kalyani motors","ap":[]}], 

but when i use at dynamically its converted like this

[" {\"loc_name\":\"pronto="" network="" office\",\"address\":\"3rd="" floor,="" kalyani="" motors\",\"ap\":[]}"]

finally i want like this

<ul ng-repeat="loc in [" {\"loc_name\":\"pronto=" " network=" " office\",\"address\":\"3rd=" " floor,=" " kalyani=" " motors\",\"ap\":[]} "]"="">
    <li class="clearfix">
        <div class="list-icon">
            <i class="fa fa-user"></i>
        </div>
        <div class="location-info">
            <h4 class="location-name">{{ loc.loc_name }}</h4>
            <p class="location-address">{{ loc.address }}</p>
        </div>
    </li>
    <li ng-if="loc.aps != '' ">
        <ul ng-repeat="ap in loc.aps">
