       { 
      document.getElementById("txtHint").innerHTML=""; 
        return; 
        } 
       if (window.XMLHttpRequest) 
      {// code for IE7+, Firefox, Chrome, Opera, Safari

从Donwload链接（HREF），请删除onclick，

，并调用该函数在PHP的功能 function File_Downloads($file, $name, $mime_type='') { //Your send mail function echo '<script> function sendMail(str) { //your content } </script>'; }
