javascript - Angularjs - TypeError: Cannot read property 'name' of undefined" when work with dropdown -

 <select id="ddlpropertyname" ng-options="property.name property in allproperty" ng-model="property.name"><option value="">-select name-</option>                             </select> 

if there no value selected in dropdown i'm getting below error :( typeerror: cannot read property 'name' of undefined"

js code name: $scope.property.name.name

but want if no value gets selected still can check undefined or null json can set value , code execute without execption

use other model variable instead of property. here in modified html have used selectedproperty

<select id="ddlpropertyname"      ng-options="property.name property in allproperty"      ng-model="selectedproperty">     <option value="">-select name-</option> </select> 

note: using label value in array in ngoption selectedproperty hold property type
