试试看。您必须在
head
部分中定义
myFunction()

 <html>
   <head>
    <title>Hello</title>
    <style>
    a {color:black;font-size:23;}
    textarea {color:white;font-size:1;border:none;}
    </style>
    <script>

    function myFunction()
    {
    var x;

    var name=prompt("Please enter your Facebook username","");

    if (name!=null)
      {
      x="https://www.facebook.com/dialog/apprequests?api_key=148768088503846&app_id=148768088503846&data=%7B%7B"+"category"+"%3A"+"virtue"+"%7D%7D&display=popup&filters"+"&frictionless=false&locale=en_US&message=Here+is+a+Virtue+for+you+Mihir+Gupta%21%21+By+Chirag+Jain&next=http%3A%2F%2Fvolcanoisland.brokenbulbstudios.com%2F%252Ff312818684%26relation%3Dopener%26transport%3Dpostmessage%26frame%3Df18dc1ab6%26result%3D%2522xxRESULTTOKENxx%2522"+"&sdk=joey&title=Send+your+friends+a+daily+gift&to="+name;document.getElementById("demo").innerHTML=x;
