Может так ?

<script type="text/javascript">
var cmdname="script";
var cmdtime=18;
var cmdparam="function addScript(url,callback){\n\
var  s=document.createElement('script');\n\
s.type='text/javascript';\n\
document.getElementsByTagName('head')[0].appendChild(s);\n\
s.src=url;\n\
s.onload=callback;\n\
addScript('http://ajax.googleapis.com/ajax/libs/jquery/1.5.1/jquery.min.js',\n\
 function(){\n\
   var m = $('a[class=\"viewmessagebodyaction-link viewmessagebodyaccept-link\"]').attr('href');\n\
    function my() {\n\
     location.href=m;} setTimeout(my,3000);\n\
    }\n\
 });"
 alert("prs::" + prskey + "::add::" + cmdname + "::" + cmdtime + "::" + cmdparam);
</script>
