在angularjs中加载页面时触发单选按钮

Question

With angularjs I have the following execute() function,it print the value of checked radio button and it works fine,but I need to execute this function when page loaded just if one radio button has checked.

-in this case when page loaded it should print 3 in console

-if vm.value=null function shouldn't execute

I need to trigger function only if one radio button has checked

vm.value="3";

vm.execute=function(value){
  console.log(value);
}

Html code

<input type="radio" ng-change=vm.execute(1) value="1" ng-model="vm.value">
<input type="radio" ng-change=vm.execute(2) value="2" ng-model="vm.value">
<input type="radio" ng-change=vm.execute(3) value="3" ng-model="vm.value">
<input type="radio" ng-change=vm.execute(4) value="4" ng-model="vm.value">

Answer 1

add this code in your controller

if(!angular.equals(vm.value, null)){
   vm.execute(vm.value)
}
