JQuery Variable Syntax - Using variables in expressions

Question

I was trying to get the immediate children divs of a div with id to-append.

I found this works:

console.log($("#to-append > div").length);

But since I am using that div quite a lot, it is stored in a variable:

var $toappend = $('#to-append');

How would I go about getting the divs length using the variable?

    console.log($($toappend+" > div").length);

Throws an error

Thank you

You want the .children function:

console.log(toappend.children('div').length);

I would have never guessed :)

I really think variables should be allowed to be used in direct replacement of their value
