Angular's dynamic attribute functionality

Is there a way to add the lang='fa' attribute to all input:text elements in my form using Angular?

I have a specific condition in mind: if the body of the document has the class 'fa', I want to apply the lang="fa" attribute to all input:text elements that are not of type email.

While I know how to achieve this using jQuery, I am unsure of how to do it in an Angular-specific manner.
You can find an example of what I want to achieve with jQuery in this fiddle: Demo
Jquery :

$(document).ready(function(){
        if($("body").hasClass('fa')){
            if('input:text'){
                $('input:text').attr('lang','fa');
            }
        }
    });

Answer №1

To enhance the functionality of the input directive (or any other directive), you can simply declare it again. Implementing the code below will achieve your desired outcome:

// Assuming that the variable isFa has already been defined, for example:
var isFa = angular.element(document.body).hasClass('fa');

app.directive('input', function() {
    return {
        restrict: 'E',
        link: function(scope, elem) {
            if(isFa && elem.attr('type') === 'text') {
                elem.attr('lang', 'fa');
            }
        }
    };
});

No jQuery required. Check out the live demonstration on fiddle: http://jsfiddle.net/b37wdm07/
