Divide a string into various text boxes

Question

Divide a string into various text boxes

Is there a way to allow users to edit the value of a field that is Vertex 3D? The stored value is in string format, but I want to present it to the user as three separate input fields for easier editing.

I am looking for a method to split the string by spaces and display each index in a separate input field. I attempted to use a filter for this purpose:

myApp.filter('split', function() {
  return function(input, splitChar, splitIndex) {
    return input.split(splitChar)[splitIndex];
  }
});

<input type="text" ng-model="value | split:' ':0"/>
<input type="text" ng-model="value | split:' ':1"/>
<input type="text" ng-model="value | split:' ':2"/>

However, as filters cannot be assigned a value, it results in an error being thrown.

What would be the correct approach to achieve this functionality? Any advice is greatly appreciated!

Answer №1

If you want to display parts of a string in separate inputs, consider splitting the string by spaces:

Angular variables

$scope.myString = 'My fantastic example';
$scope.arr = $scope.myString.split(/[ ]+/);

HTML inputs

<input type="text" ng-model="arr[0]" />
<input type="text" ng-model="arr[1]" />
<input type="text" ng-model="arr[2]" />

Give it a go on JSFiddle.

Here is a solution:

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

vertexApp.controller('vertexCtrl', ['$scope', function ($scope) {

    $scope.coordsString = 'xxx yyy zzz';
    $scope.coords = $scope.coordsString.split(' ');

    $scope.$watch('coords[0]', function () {
        $scope.coordsString = $scope.coords.join(' ');
    });

    $scope.$watch('coords[1]', function () {
        $scope.coordsString = $scope.coords.join(' ');
    });

    $scope.$watch('coords[2]', function () {
        $scope.coordsString = $scope.coords.join(' ');
    });
}]);

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>

<div ng-app="vertexApp">
    <div ng-controller="vertexCtrl">
        <input type="text" ng-model="coords[0]" />
        <input type="text" ng-model="coords[1]" />
        <input type="text" ng-model="coords[2]" />
        <br />
        New value for model: {{coordsString}}
    </div>
</div>

Enhancing readability and efficiency, it would be beneficial to implement a structure similar to the following:

Controller:

...
let vertexParts = vertex.split(' ');
$scope.vertex3d = {x: vertexParts[0], y: vertexParts[1], z: vertexParts[2]};
....
$scope.saveVertex = function() {
    myVertexService.save([$scope.vertex3d.x, $scope.vertex3d.y, $scope.vertex3d.z].join(' '));
};
...

Template:

<label>
    X: <input type="text" ng-model="vertex3d.x"/>
</label>
<label>
    Y: <input type="text" ng-model="vertex3d.y"/>
</label>
<label>
    Z: <input type="text" ng-model="vertex3d.z"/>
</label>
