Trigger event in jquery without a namespace

问题

With the current version of jQuery (1.8.3) you can still use the following code (showing both a click with and without a namespace):

$("span")
    .on("click", function(e) { console.log('click without a namespace'); })
    .on("click.namespace", function(e) { console.log('click with a namespace'); })
    .trigger("click!"); // "click without a namespace"

JSFiddle

However, that seems to be removed in 1.9. Is there a way in the new version of jQuery (the test version) to replicate this feature? Or do I have to create a custom event like this:

$("span")
    .on("click", function(e) { $(this).trigger("customevent"); })
    .on("click.namespace", function(e) { console.log('click with a namespace'); })
    .on("customevent", function(e) { console.log('"click" without a namespace'); })
    .trigger("customevent");

You can call that using

.trigger("click.$")

as we found it is because regex
