How can a controller be used to access and modify data from various partials?

I need assistance with handling multiple ng-models spread across 2 partial HTML files.

Here is the content of partial1.html:

<input ng-model="A" /> //user input for A
<input ng-model="B" /> //user input for B
<input ng-model="C" /> //user input for C
<button ng-click="SavePartialOne()> Save and navigate to partial 2 </button>

And here is the content of partial2.html:

<input ng-model="P" /> //user input for P
<input ng-model="Q" /> //user input for Q
<input ng-model="R" /> //user input for R
<button ng-click="SavePartialTwo()> Save and go to partial 3 which will be populated with data from partial1 and 2 </button>

Lastly, in partial3.html:

<input ng-model="X" /> //auto-populated with data from input box A
<input ng-model="Y" /> //auto-populated with data from inputs A and P
<input ng-model="Z" /> //slightly modified data based on input A where a is changed to a+1

I need help with app.js to access and manipulate this data. Any suggestions?

Answer №1

To start, make sure all instances of ng-model are assigned to your object as shown below:

<input ng-model="dataModel.A" />
<input ng-model="dataModel.B" />
<input ng-model="dataModel.C" />
<button ng-click="SavePartialOne()> Save and proceed to part 2 </button>

<input ng-model="dataModel.P" />

This way, it will be easier to manage and retrieve the values of these data in the SavePartialTwo function. Here's how you can organize it:

$scope.dataModel = {};

$scope.SavePartialTwo = function() {
    $scope.dataModel.X = $scope.dataModel.A;
    $scope.dataModel.Y = $scope.dataModel.A + ' ' + $scope.dataModel.P;
    $scope.dataModel.Z = $scope.dataModel.Z + 1;

    // Proceed to display your third section
};
