        if (UrlExists(address))

        }
        idCompany="821229021";
        //$.unblockUI();
    }
    if(Empty ){
        certification = "updating<br /><img src='icon/Updated.png' />";
    }
    $("#contentCertification").html(certification);
}
$.unblockUI();
</script>
HTML 

 <input type="button" value="click me" onclick="test();"/>

2)在IE中，$.blockUI()不工作，似乎浏览器已挂起。

 <script type="text/jscript" language="javascript">
应该

 <script type="text/javascript">

如何加载jQuery和插件?确保你不使用自关闭脚本标签，在IE上不起作用。

<script src="js/blockui.js" />       <!-- WRONG -->
<script src="js/blockui.js></script> <!-- CORRECT -->
