OverviewThe JQuery Blockui Plugin lets you simulate synchronous behavior when using AJAX, without locking the browser[1]. When activated, it would prevent user activity with the page (or part of the page) until it was deactivated. Blockui adds elements to the DOM to give it both the appearance and behavior of blocking user interaction.//Usage is very simple, to block user activity for the page:$.blockui ();//Blocking with a custom message:$.blockui ({message: ' });//Blocking with custom style:$
Simple Modal Dialog ExampleThis page demonstrates how to display a simple modal dialog. The button below would invoke with blockUI a custom message.
