Use the new .prop() function:
$(".myCheckbox").prop("checked", true);$(".myCheckbox").prop("checked", false);
The .prop() function is not available, so you need to use .attr().
To check the checkbox (by setting the value of the checked attribute) do
$('.myCheckbox').attr('checked','checked')
and for un-checking (by removing the attribute entirely) do
$('.myCheckbox').removeAttr('checked')
Industry standards and innovation took center stage at MIX10, as Microsoft Corp. made a series of announcements that underscore the company’s commitment to interoperability and performance on the Web. Dean Hachamovitch, general manager of Internet Explorer at Microsoft, unveiled the Internet Explorer 9 Platform Preview including expanded support for HTML5, hardware-accelerated graphics and text, and a new JavaScript engine. Together these allow developers to use the same markup and deliver graphically and functionally rich Web applications that take advantage of modern PC hardware through a modern operating system.
Microsoft also announced that it will contribute to the development of new features and enhancements in the jQuery JavaScript Library and shared the release of new software development kits (SDKs) for the Open Data Protocol (OData) that make it easier for developers to access data from the cloud to create more compelling cross-platform Web applications.
As part of Microsoft’s broad engagement with open source communities, Corporate Vice President Scott Guthrie today announced that Microsoft is investing resources to contribute to the development of the jQuery JavaScript Library to help improve the development process of standards-based Web applications. Microsoft will also work to provide better interoperability between ASP.NET and the jQuery JavaScript Library by enhancing ASP.NET so .NET developers can better incorporate jQuery capabilities. In addition, Microsoft will actively promote and distribute versions of the jQuery JavaScript Library by packaging it with popular products such as Microsoft Visual Studio 2010 and ASP.NET MVC 2. As a first step, Microsoft will contribute a templating engine to the jQuery JavaScript Library Team to simplify Web applications.
In celebration of jQuery’s 4th birthday, the jQuery team is pleased to release the latest major release of the jQuery JavaScript library! A lot of coding, testing, and documenting has gone into this release, and we’re really quite proud of it.
