jQuery's attr method returns the value of the attribute:
The
.attr()method gets the attribute value for only the first element in the matched set. To get the value for each element individually, use a looping construct such as jQuery's.each()or.map()method.
All you need is:
$('html').attr('lang') == 'fr-FR'
However, you might want to do a case-insensitive match:
$('html').attr('lang').toLowerCase() === 'fr-fr'
jQuery's val method returns the value of a form element.
The
.val()method is primarily used to get the values of form elements such asinput,selectandtextarea. In the case of<select multiple="multiple">elements, the.val()method returns an array containing each selected option; if no option is selected, it returnsnull.
