Variable, which is an ID JQuery

Question

I have a variable called counter, which represents the id of an element.

How would I select this variable's value e.g. the div with the id, which is the value of the variable, in jQuery?

counter = counter + 1;
$('<a> </a>').hover(  function() {
    $(#/*id is the value of variable counter*/).
}

you can give unique class name to that div n get the id of that div with attr. — Pratik Gadoya, Sep 01 '14 at 13:34

@zerkms In HTML5, id's can contain just numbers. Although, I agree browser support is usually very important. See http://stackoverflow.com/questions/70579/what-are-valid-values-for-the-id-attribute-in-html — Stryner, Sep 01 '14 at 13:38

$("#"+variable)

That's it! You can combine it even different way, because as mentioned in comments it shouldn't be number.

$("#element_"+variable)

etc.

Or by attribute

$("a[data-value="+counter+"])

And HTML part

<a data-value="1"></a>
