First, sorry if this is a duplicate, but I could not search because the server tells me

The actual bug: It is no longer possible to set the (valid HTML) size attribute of an input element in jQuery 1.8.0. This used to work fine in 1.7.2. It works fine for all other attributes (which I tested) and it's not mentioned in the changelog (which only mentions deprecating size(), but that's something different).

var inputBox = $('<input>', {
    type: "text",
    size: "99",
    value: "abcdefghijklmnopqrstuvwxyz"

Resolution: wontfix
Status: newclosed

Apologies for the misbehaving bug tracker, it's really acting up today.

This is due to a 1.8 enhancement in $(html, props) that allows you to call any method instead of just a small group of whitelisted methods. Since there is still a (deprecated) .size() method, that is attempting to call the method with "99" as an argument.

I agree it's a regression, but one I don't think we will back out. The $(html, props) signature is inherently ambiguous about the meaning of the object keys, which is why I dislike it so much.

There are several solutions. The first is to not use it at all, since it doesn't save you any space and this improves the clarity of the code:

var inputBox = $('<input>')
  .attr({ type: "text", size: "99" }) 

The other solution is to call .attr explicitly in the props object, either for all the attributes or just the size one.

var inputBox = $('<input>', {
    type: "text",
    attr: { size: "99" },
    value: "abcdefghijklmnopqrstuvwxyz"

Or use width instead of size which is more explicit...

Still now Size works instead of size, http://stackoverflow.com/a/19576388/741747.
