Is it okay show some ids in html?

Is it okay to generate HTML page like this:

...
<div id='some_id' lesson_id='313'>
 ...
</div>
...

And in jQuery just do

lesson_id = $("#some_id").attr("lesson_id")
// send some AJAX POST requests with this lesson_id

Is it normal way to pass some data to js from server side ?

Many thanks!

Use jQuery Data 

<div id='some_id' data-lessonid='313'>
 ...
</div>

lesson_id = $("#some_id").data("lessonid")

So long as it doesn't reveal any major information that a malicious user can exploit, you can do that. As has been said, though, you should add the data-* attribute prefix, as this allows you to have custom HTML that's still considered valid.

Use the data attributes:

<div id="some_id" data-lesson_id="313">

then in jQuery get the value:

var lesson_id = $('#some_id').data('lesson_id');
