Jquery .size()

I am writing a plugin for a select box. I need to get the size of the options before performing an action. How can i do this?

Sample code:


jQuery.fn.doSomething = function(options){
    return this.each(function(){
        var optionsSize = this.find("options").size();
        
    });
};


I am getting an error:


this.find is not a function
var optionsSize = this.find("options").size(); 

try

var sizeOption = $(this).find(…)

<snip/>

I have tried this and results in 0 size.
