Modify the name format using an AngularJS directive

Question

Modify the name format using an AngularJS directive

I've been struggling to understand how to effectively write AngularJS directives, even after reading various blogs. The issue I am facing is with an array of names in the format "lastname, firstname". My goal is to create a directive that will display them as "firstname lastname."

Here is the structure of my HTML:

<div ng-repeat="names in nameArray"
    <custom-name-format> {{names}} </custom-name-format>
</div>

Could you please guide me on how to pass the 'names' parameter to the directive?

Controller:

angular.module('nameApp').directive('customNameFormat', function() {
    
    // How can I access and manipulate {{names}} within this directive?
});

Answer №1

Consider using filter in place of directive.

Take a look at the JsFiddle demo.

Example Codes:

HTML:

<div ng-app="myApp">
    <ul ng-controller="YourCtrl">
       <li ng-repeat="name in names">
           {{name.name | customNameFormat}}
        </li>
    </ul>
</div>

JS:

'use strict';

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

app.controller('YourCtrl', ['$scope', function ($scope) {

    $scope.names = [
        {name:'Doe, John'},
        {name:'Naperi, Alberto'},
        {name:'Last, First'},
        {name:'Espolon, Justin'},
        {name:'Bor, Em'},
        {name:'Pik, El'},
      ];

}]);

app.filter('customNameFormat', function() {    

    return function(input) {
        var nameStr = input.split(',').reverse().join(' ');
        return nameStr;
    };

});

Hopefully this solution works for you.

Answer №2

It seems like a directive is unnecessary in this case. A filter would be a better choice, and you can easily pass arguments to the filter.

Here's how it looks in HTML:

{{ dataToFilter | myCustomFilter : argument}}

And here's how you do it in JavaScript:

$filter('myCustomFilter')(dataArray, argument)

Within the directive

angular.module('nameApp').directive('customNameFormat', function() {
  return{
    scope:{
    names : '='
    },
    link: function(scope,elem,attr){
       var nameStr = scope.names //lastname, firstname
       var newNameStr = nameStr.split(',').reverse().join(' ');
       elem.html(newNameStr);

    } 

 }

})

<div ng-repeat="names in nameArray"
   <custom-name-format names="names" ></custom-name-format>
</div>

Answer №4

To assign a specific attribute to the name, use the following method:

<div ng-repeat="names in nameArray">
    <custom-name-format custname="{{names}}"> {{names}} </custom-name-format>
</div>

Then, you can retrieve the names assigned to custname in your directive using this syntax:

scope: {
  custname: '@'
}

Answer №5

Using Angular, you have the option to access attributes in a similar way to using jQuery.

<div ng-repeat="names in nameArray"
    <custom-name-format custom-attr="{{name}}"> {{names}} </custom-name-format>
</div>

controller:

angular.module('nameApp').directive('customNameFormat', function() {

     return {
        restrict: 'A',

        link: function (scope, el, attrs) {
alert(attrs.customAttr);
}
}
});

If you need to reorganize a name, consider utilizing regex matching.

const segments = fullName.match(/(\w+), (\w+)/)
segments[2] + " " + segments[1]
