JavaScript for detecting browser language preference

Posted on by

Just not to forget:

[javascript]
var language = window.navigator.userLanguage || window.navigator.languages[0];
[/javascript]

and more crazy(but more trustful) way:

[javascript]
$.ajax({
url: "http://ajaxhttpheaders.appspot.com",
dataType: ‘jsonp’,
success: function(headers) {
var language = headers[‘Accept-Language’];
}
});
[/javascript]

AngularJS Directive attribute binding options

Posted on by

This example explicitly shows the difference between directive attribute binding types. Let’s say you have directive:

[javascript]
function myDirective() {
return {
scope: {
x: ‘@’, // String, interpolated with {{ }}
y: ‘=’, // Expression
z: ‘&’ // Function
}
};
}
[/javascript]

it means that you will do such operations with attributes to pass the directive:

[javascript]
function MyDirectiveController($scope, $element, $attrs, $interpolate, $parse) {
$attrs.$observe(‘x’, function(value) {});
$interpolate($attrs.x)($scope);
$scope.$eval($attrs.y);
var fn = $parse($attrs.z);
$element.on(‘click’, function() {
fn($scope);
});
}
[/javascript]
