我和jQuery Thickbox有一个类似的问题样式对话框小部件）。我修复我的问题的方式如下：

I had a similar problem with the jQuery Thickbox (a lightbox-style dialog widget). The way I fixed my problem is as follows:

function setFocusThickboxIframe() {
    var iframe = $("#TB_iframeContent")[0];
    iframe.contentWindow.focus();
}

$(document).ready(function(){
   $("#id_cmd_open").click(function(){
      /*
         run thickbox code here to open lightbox,
         like tb_show("google this!", "http://www.google.com");
       */
      setTimeout(setFocusThickboxIframe, 100);
      return false;
   });
});

如果没有setTimeout（），代码似乎不起作用。根据我的测试，它适用于Firefox3.5，Safari4，Chrome4，IE7和IE6。

The code doesn't seem to work without the setTimeout(). Based on my testing, it works in Firefox3.5, Safari4, Chrome4, IE7 and IE6.
