Unable to Extract the Text Content of Element using Class in Web Scraping

I am trying to make a Web Scraper using Javascript. I need to extract the number 1214 from this Element: -

<span class="ss-icon-user num-students left">
        1,214
    </span>

Now I have written this code for it :-

var students = $('.ss-icon-user num-students left');

var no_of_students = students.text();

console.log(no_of_students);

but it gives no output at all. I tried :-

console.log(no_of_students.length);

and it gives the output 0.

Can anyone tell me why am I unable to extract it? What changes do I have to make?

Try to do this:

$('.ss-icon-user.num-students.left').html();

You need to put dot "." in every class inside your tag.

Your selector is wrong. The span has 3 different classes - ss-icon-user, num-students, and left. Your selector is looking for elements with the ss-icon-user class which have a child "num-students" TAG with in turn has a child "left" TAG. If you want to select multiple classes, you would do it like this:

var students = $('.ss-icon-user, .num-students, .left');

Note that this could potentially pull back multiple entries if more than one element has all three of these classes.
