Within an Angular (1.5) setting, I am confronted with a form containing two input sections:
The requirements are as follows:
What steps can be taken to bring about this desired outcome?
<input type="text" name="website"
ng-model="urlInput"
ng-model-options="{ getterSetter: true }" />
...
function setDefaultUrl() {
if $scope.ID {
return 'http://myurl/'+$scope.ID+'.html';
}
return ''
}
var _defaultUrl = setDefaultUrl();
$scope.urlInput = {
url: function(newUrl) {
return arguments.length ? (_defaultUrl= newUrl) : setDefaultUrl();
}
}
};
Implement a $watch function on the ID Field. This function will trigger whenever there is a change in the ID field.
$scope.$watch('$scope.ID', function() {
$scope.url = 'http://myurl/' + $scope.ID + '.txt';
}, true);

Below is the code snippet:
//HTML
<div ng-app="myApp" ng-controller="MyController">
ID <input type="text" ng-model="data.id" ng-change="onIDChange()"/>
URL <input type="text" ng-model="data.url" ng-change="onManualUrlChange()"/>
</div>
//JS
angular.module('myApp',[])
.controller('MyController', ['$scope', function($scope){
$scope.data = {
id:'',
url:''
}
$scope.manualUrl = false;
$scope.onIDChange = function(){
if(!$scope.manualUrl){
if($scope.data.id === ''){
$scope.data.url = '';
} else {
$scope.data.url = "http://myurl/" + $scope.data.id + ".txt";
}
}
}
$scope.onManualUrlChange = function(){
$scope.manualUrl = true
};
}]);
