blockUI1.33参数

The jQuery BlockUI Plugin lets you simulate synchronous behavior when using AJAX, without locking the browser^[1]. When activated, it will prevent user activity with the page (or part of the page) until it is deactivated. BlockUI adds elements to theDOM to give it both the appearance and behavior of blocking user interaction.

    这个插件可以让你锁定浏览器从而组织用户的操作直到解锁。    使用非常简单。

    锁定：

$.blockUI();
   
    解锁锁定：

$.unblockUI();

   在Ajax中使用。当触发Ajax是进行锁定，结束时解锁：

$().ajaxStart($.blockUI).ajaxStop($.unblockUI);

   以下是BlockUI默认参数配置：



$.blockUI.defaults = {     // message displayed when blocking (use null for no message)      message:  '<h1>Please wait...</h1>',      // styles for the message when blocking; if you wish to disable     // these and use an external stylesheet then do this in your code:     // $.blockUI.defaults.css = {};      css: {          padding:        0,          margin:         0,          width:          '30%',          top:            '40%',          left:           '35%',          textAlign:      'center',          color:          '#000',          border:         '3px solid #aaa',          backgroundColor:'#fff',          cursor:         'wait'      },      // styles for the overlay      overlayCSS:   {          backgroundColor:'#000',          opacity:        '0.6'      },      // styles applied when using $.growlUI      growlCSS: {          width:    '350px',          top:      '10px',          left:     '',          right:    '10px',          border:   'none',          padding:  '5px',          opacity:  '0.6',          color:    '#fff',          backgroundColor: '#000',         '-webkit-border-radius': '10px',         '-moz-border-radius':    '10px'      },      // z-index for the blocking overlay      baseZ: 1000,      // set these to true to have the message automatically centered      centerX: true, // <-- only effects element blocking (page block controlled via css above)      centerY: true,      // allow body element to be stetched in ie6; this makes blocking look better     // on "short" pages.   disable if you wish to prevent changes to the body height      allowBodyStretch: true,      // be default blockUI will supress tab navigation from leaving blocking content;      constrainTabKey: true,      // fadeIn time in millis; set to 0 to disable fadeIn on block      fadeIn:  200,      // fadeOut time in millis; set to 0 to disable fadeOut on unblock      fadeOut:  400,      // time in millis to wait before auto-unblocking; set to 0 to disable auto-unblock      timeout: 0,      // disable if you don't want to show the overlay      showOverlay: true,      // if true, focus will be placed in the first available input field when     // page blocking      focusInput: true,      // suppresses the use of overlay styles on FF/Linux (due to performance issues with opacity)      applyPlatformOpacityRules: true,      // callback method invoked when unblocking has completed; the callback is     // passed the element that has been unblocked (which is the window object for page     // blocks) and the options that were passed to the unblock call:     //      onUnblock(element, options)      onUnblock: null,      // don't ask; if you really must know: http://groups.google.com/group/jquery-en/browse_thread/thread/36640a8730503595/2f6a79a77a78e493#2f6a79a77a78e493      quirksmodeOffsetHack: 4 };
