angular.js, can't edit dynamically created input fields

Question

Using angular.js, I have a dynamic list of form fields I want to display to the user for editing (and later submission):

var app = angular.module(\'app\', []         


        

Answer 1

SET answered why it's happening, but a work-around to achieve the desired behavior would be to maintain a separate array of your keys, and run ng-repeat off those keys. I added some text fields for testing to add more properties to $scope.fields

You could use $watch to dynamically set the keys when the property count changes, if your requirements were that the field count may change.

markup

    

        
key
        
value
        

            
{{key}}:
            

        
    
    
Add a field
        key: 

        value: 
        Add Field
    

controller

var app = angular.module('app', []);

app.controller('Ctrl', function($scope) {
    $scope.fields = {
        foo: "foo",
        bar: "bar",
        baz: "baz"
    };
    $scope.fieldKeys = [];

    $scope.setFieldKeys = function() {
        var keys = [];
        for (key in $scope.fields) {
            keys.push(key);
        }
        $scope.fieldKeys = keys;
    }

    $scope.addField = function() {
        $scope.fields[$scope.keyToAdd] = $scope.valueToAdd;
        $scope.setFieldKeys();
        $scope.keyToAdd = '';
        $scope.valueToAdd = '';
    }

    $scope.setFieldKeys();
});
