Question

所以，我正在努力建立一个网站，我可以在这里每天都有变化的图片。我需要帮助将图像源设置为变量imageurl。另外，使变量imageurl成为全局变量。

让我澄清一下，我希望它能将变量imageurl设置为由提示设置的链接，然后将图像设置为imageurl。

                    alert("password:" + isitjere + " " + "has been accepted");
                var editimage = prompt("do you want to change the image?(type yes or no)");
                if (editimage === "yes")
                    var imageurl = prompt("paste the image url(if you dont have a url for it you can upload it and paste the upload link)");
      console.log(imageurl);
    $("#pic").attr('src',imageurl);
