jQuery 1.4 is released

January 14 2010, 9:13pm

The incredibly popular jQuery library has released jQuery 1.4 on a new website that will celebrate 14 days of jQuery. There are a lot of new features, and as usual performance gains are showcased.

Easy Setter Functions: For a while now, you’ve been able to pass a function into .attr() and the return value of that function is set into the appropriate attribute. This functionalilty has now been extended into all setter methods

Ajax: A lot of enhancements to the various remoting functions including support for native JSON parsing, etags, request context, and more

.css and .attr have been improved

Per property easing on effects

If you want to ensure that “this” inside a function will be permanently bound to a particular value, you can use jQuery.proxy to return a new function with that scope

New events: focusin and focusout

And Joe Walker will be really excited to see that dojo.create has made it in! :) PLAIN TEXT [removed]

jQuery("<div />", {

    id: "foo",

    css: {

        height: "50px",

        width: "50px",

        color: "blue",

        backgroundColor: "#ccc"

    },

    click: function() {

       $(this).css("backgroundColor", "red");

    }

}).appendTo("body");

Congrats to the jQuery team. I look forward to seeing posts over the next 2 weeks that go into more detail on the new coolness.
