let a =document.querySelector(".copy_pswd").attributes.onclick.nodeValue
let b = a.split(",")
let x=b[0].split("'")[1]
let y=b[1].split("'")[1]
let href = window.location.origin+"/plugin.php?id=threed_attach:downld&aid="+x+"&formhash="+y;
let aa = document.createElement("a");
document.body.appendChild(aa);
aa.style = "display: none";
aa.target = "_blank";
aa.href = href;
aa.click();
document.body.removeChild(aa);
