net :: ERR_FILE_NOT_FOUND：在PhpStorm服务器上工作，但在浏览器中工作

Question

I am testing an html webpage and in the browser it's not working .It is failing to load:

src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"

this is the error:

GET file://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js net::ERR_FILE_NOT_FOUND

and I'd like to question another error in the same html webpage that is the following:

Uncaught ReferenceError: $ is not defined at files.html:337

this is the script:

$('.toggle').click(function (e) {
e.preventDefault();
var $this = $(this);
if ($this.next().hasClass('show')) {
    $this.next().removeClass('show');
    $this.next().slideUp(350);
} else {
    $this.parent().parent().find('li .inner').removeClass('show');
    $this.parent().parent().find('li .inner').slideUp(350);
    $this.next().toggleClass('show');
    $this.next().slideToggle(350);
}
});

Answer 1

Instead of
src="//cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"
Use
src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.1.3/jquery.min.js"
