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

function UrlExists(url)
{
    var http = new XMLHttpRequest();
    http.open('HEAD', url, false);
    http.send();
    return http.status!=404;
}

function test()
{
    var  certification = "";
    var address;
    var  idCompany="821229021";
    var Empty = true;
    for (var  i = 0; i < 10; i++)                                 
    { 
        idCompany =idCompany + i.toString();
        idCompany=idCompany + ".png";
        address="Image/CertificationCompany/"+idCompany; 

        if (UrlExists(address))
        {
            //certification += "<img style='margin:5px;padding:5px;cursor: pointer; border: 1px solid GrayText;' width='103px' height='80px;' src='Image/CertificationCompany/" + idCompany + "' />";                               
             certification +="<a href='Image/CertificationCompany/" + idCompany + "' rel='prettyPhotoCertification[pp_gal]' title=' ?????? ????????? ???? "+document.title+"'><img style='margin:5px;padding:5px;cursor: pointer; border: 1px solid GrayText;' width='103px' height='80px;' src='Image/CertificationCompany/" + idCompany + "'  alt='????????? ??' /></a>";                      

            Empty = false;
        }

        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() 不起作用，浏览器似乎已挂起。

Answer 1

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

应该是

 <script type="text/javascript">

Answer 2

你是如何加载 jQuery 和插件的？确保您不使用自关闭脚本标记，该标记在 IE 上不起作用。

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