When you create a new HTML element, you may want to keep its reference and later add a few more properties to it in the script. Just store it in a var, and continue accessing it. See below for an example.

var myDiv = $("
Dummy Content
");…../*Later access the jQuery object with the var name and continue working with the object*/myDiv.attr("id", "newlyCreatedDev");myDiv.attr("class", "div mClass").appendTo("body");
