angular.js - An error occurred when adding a new attribute assignment in angularjs. What happened?

Question

For example, I pass in a serach object below

In html web page:

<select ng-model="Temp" ng-options="c.abbrZh for c in corpss">

In js.....

$scope.search = function(searchObj){

console.log($scope.Temp.corporationId);
$scope.searchObj.name=$scope.Temp.corporationId;

}

console.log($scope.Temp.corporationId);
There is value here.
But $scope.searchObj.name=$scope.Temp.corporationId;
An error occurs when assigning like this, saying name is not defined. What's going on?
angular.yh.js:12454 TypeError: Cannot set property 'name' of undefined

To solve, how to assign value? ? How to assign the value on the right to the new attribute of the coordinate?

Answer 1

It means you haven’t defined itsearchObj. At least you can define this object:

$scope.searchObj = {};

$scope.search = function(searchObj){
    console.log($scope.Temp.corporationId);
    $scope.searchObj.name=$scope.Temp.corporationId;
};

Answer 2

It’s because your $scope.searchObj has no value assigned, and the result becomes undefined.name, which must be an error
