Jquery: How to clear an element before appending new content?

Question

This is my jquery code

 $.ajax({
   url: \"PopUpProductDetails.aspx\",
            cache: false
     }).done(function (html) {
     $(\"#dialog\").append(htm         


        

Answer 1

in case you need to clear the dialog first use .empty() which is faster than .html("")

see Jquery Difference .html("") vs .empty()
