.html() bug with JQuery objects

[Jamie Clarke]

When using .html() on a JQuery object, all classes added using JQuery (.addClass, .attr("class")) are removed.

Eg.

var element = $("<div></div>");

for(var i = 0; i < 5; i++) {
    var otherElement = $("span class=\"someClass\">some text</span>");
 
    otherElement.addClass("someOtherClass");

    element.append(otherElement);
}

// For firebug:

console.log(element) // shows all classes whether added with addClass or in the html when creating other element

console.log(element.html()) // shows only class added in html when creating other element (the "someClass" class)

This method was using when creating elements from an AJAX request, the workaround i have used for now (not using .html() and removing the existing element) for anyone with the same issue - but i would be interested to know why this happens.

Thanks for taking the time to contribute to the jQuery project! Please provide a complete reduced test case on jsFiddle to help us assess your ticket.

Additionally, be sure to test against the jQuery Edge version to ensure the issue still exists. To get you started, use this boilerplate: ​http://jsfiddle.net/FrKyN/ Open the link and click to "Fork" (in the top menu) to get started.

A couple things I notice are the missing '<' in the html for otherElement and the lack of actually printing the classes.
