jQuery Select by ID with variable

I have some code that creates some span tags and each span has its own ID

counter1
counter2
counter4

by its name in the database. Now I'm trying to reach the value of one of them. So, I tried something like this:

var id = // Any number that have a span.
var Counter = $("#counter" + id).val();
alert(Counter);

But, it's just showing "NaN"

Mmmmm try:

var Counter = $("#counter" + id).html();

or

var Counter = $("#counter" + id).text();

I´m dont sure, but maybe span dont have "value" attribute.

You cannot get a val()ue of a <span>. You have to use html() or text().

Change .val() to .html() to access the innerHtml of an html element. .val() selects the value of an html input element as detailed in the API.

var id = // Any number that have a span.
var Counter = $("#counter" + id).html();
alert(Counter);
