   You don’t need the “> 0″, you can simply write:

   
if ( $('#myElement').length ) {
// it exists
}

     No true, since jQuery always returns an object with length 0

     it’s true. If element exists: length > 0, and condition is true.
     If element not exosts: length = 0 and condition is false

   Even easyest and reusable, you can define a function:

   jQuery.fn.exists = function() { return this.length>0; };

   And use it, anywhere, simple like this:

   if ($(‘#myElemento).existe()) { … }

   Better,

   if($(element).size()){
   // …
   }

     That’s not better at all. jQuery#size simply returns the length property, so just save the function call and access the length property directly.
