 <div class="mt10" ng-init="getpaymentdetailsbyid()">         <div class="panel">           <div class="form-group">             <label> name:</label>                 <span class="rightside">                         <input type="text" value="" ng-model="singlegatewaydetails.name" >                </span>           </div>           <div class="form-group">             <label> app :</label>             <span class="rightside">                        <input type="text" value=""  ng-model="paymentdetails.id" ng-disabled="appid">             </span>           </div>           <div class="form-group">             <label> app key:</label>               <span class="rightside">                          <input type="text" value=""  ng-model="singlegatewaydetails.appkey" >                </span>           </div>           <div class="form-group">             <label> app secret:</label>               <span class="rightside">                          <input type="text" value=""  ng-model="singlegatewaydetails.appsecret">               </span>           </div>          </div>       </div> 

now

<span class="rightside">                            <input type="text" value=""  ng-model="paymentdetails.id" ng-disabled="appid">                 </span> 

this code displays data in textbox. , want display data in textbox in both scenario, while editing , while posting new data server. displays while editing not when want post new data server. textbox have value pre-filled in it. guessing have use condition on that. please me how achieve that.

i think know getting at. without seeing js file hard give example, using $scope.value in js , setting text {{value}} in html should provide desired result.
