<label>Capital
<input type="number" ng-model="vm.capital" ng-keyup="vm.total()">
</label>
<label>Honorarios
<input type="number" ng-model="vm.honorarium" ng-keyup="vm.total()">
</label>
<h1>{{ vm.sum }}</h1>
The function:
this.total = function(){
this.sum = capital + honorarium;
}
I need to make the sum between capital and honorarium. But my solution does not work, maybe I have some problem in logic.
If it's the only thing you need, you can use it in the following way
<label>
Capital
<input type="number" ng-model="capital">
</label>
<label>
Honorarios
<input type="number" ng-model="honorarium">
</label>
<h1>{{capital + honorarium }}</h1>
You do not need to use any ng-X function to do this process, remember that these variables are kept in the $ scope, who is in charge of updating the information of them immediately ..
what you do inside the h1 is only add what is contained in your ng-model ..
