我在使用 jQuery Thickbox(一个灯箱样式的对话框小部件)时遇到了类似的问题.我解决问题的方法如下:

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()，代码似乎无法工作.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.
