使用API​​函數在Javascript

Question

在下面的代碼，我怎麼能使用ArrowChat Javascript API的getUser()函數來獲取用戶的化身路徑和替代IMG-NO-avatar.gif？

<script type="text/javascript"> 
window.onload=function(){ 
     var elem=document.createElement("img"); 
     elem.src= "/press/chat/admin/images/img-no-avatar.gif"; 
     elem.height="32"; 
     elem.width="32"; 
     document.getElementById("chattab_inner").appendChild(elem); 
} 
</script>

我有這個API，但是從我猜的UserDocs粗略地看一眼沒經驗...

<script type="text/javascript"> 
    window.onload = function() {  
     jqac.arrowchat.getUser('5','useravatarpath'); 
    } 

    function useravatarpath(data) { 
     var elem = document.createElement("elem"); 

     if(data.a !== 'itsJavaScriptSoProbablyUndefined') { 
      elem.src=data.a; 
     } 
     else { 
      elem.src= "/press/chat/admin/images/img-no-avatar.gif; 
     }  

     elem.height="32"; elem.width="32"; 

     // this bit i dont have time for now... 
     document.getElementById("chattab_inner").appendChild(elem); 
    } 
</script>
