在Angular控制器中进行Restangular POST之前更改表单数据

Question

I have a form where I need to edit input values. For instance, I have a number of input controls that I want to change the value before the POST happens. I my html:

<input type="text" name="bar" id="bar" ng-model="foo.bar"/>

My Go struct:

type Foo struct{
  Bar string `json:"bar"`
}

My Angular controller:

Restangular.all('drugs/new').post($scope.drug).then(......

Before I call .post(), I want to get the input element and set a value. When I do so, right before this POST call, the new value does not get sent in the json.

Answer 1

I'm assuming that the value of $scope.drug relates directly to the values of those inputs because otherwise you would have posted the relevant code, wouldn't you.

AngularJS provides 2-way bindings which means that if the value of $scope.drug depends directly on the input elements you mention, then the relation also goes in the other way i.e. if you change the value of $scope.drug, then the inputs will change.

So the solution is simple; change the value of $scope.drug.
