<script type="text/javascript" language="javascript"> 
$.blockUI({ overlayCSS: { backgroundColor: 'orange'} , message: '<img src="icon/wait.gif" /><div style=\'font-family:Tahoma;font-size:large\'> ...???? ??? ???? ??? ????</div>' });     

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，看來，瀏覽器已經掛起。

爲什麼使用內嵌JavaScript，'onclick ='，當你有jQuery？ – Sparky

這些樣本的真正好處在於它們都沒有加載。 – SeinopSys
