Converting classic asp to javascript: How to write or make returned string (json+ld) visible in header of webpage using javascript?

Question

I have this Classic Asp code in header section of webpages:

<%
dim url, param, avgrate, votes, p, s
 url = "https://au2mailer.com/api/a2m-getschemaorg.asp"
 param = "?apikey=fe9fc289c3ff0af142b6d3bead98a923"
 Set HttpReq = Server.CreateObject("MSXML2.ServerXMLHTTP.6.0")
 HttpReq.SetOption(2) = 8192
 HttpReq.open "GET", url & param, false
 HttpReq.setRequestHeader "Content-Type", "application/json"
 HttpReq.Send()
 if (HttpReq.status = 200) Then
   response.write(HttpReq.responseText)
 end if
%>

and it works and is accepted by Google Schema Markup Validator. Page to check https://carmagic.dk/online-bil-forretning-hvordan.asp (Danish website) I need to change the code so that it works whether the page is html, asp, aspx or php and my idea was to change it to javascript. I have tried this javascript in header section

  <script>
      var request = new XMLHttpRequest();
        request.open('GET', 'https://au2mailer.com/api/a2m-getschemaorg.asp?apikey=fe9fc289c3ff0af142b6d3bead98a923');
        request.send();
        request.onload = ()=>{
          var receivedDom = new DOMParser().parseFromString(request.response, "text/html");
          var jsonstr = receivedDom.body.innerText;
          document.write(jsonstr);
        }
  </script>

The code execute but it does not work as the classic asp code! Is my classic asp code not possible in javascript?

  <p id="a2mjson"></p>
  <script>
      var request = new XMLHttpRequest();
        request.open('GET', 'https://au2mailer.com/api/a2m-getschemaorg.asp?apikey=fe9fc289c3ff0af142b6d3bead98a923');
        request.send();
        request.onload = ()=>{
          document.getElementById("a2mjson").innerHTML = request.response;
        }
  </script>

Using p tag works and make the script readable by schema validation tools but is it really necessary to use the p tag ?? seems amateurish??

您沒有為 JSON 輸出響應 header 並且 javascript 假設它是 ZB45CFFE0845DD3D20D1ZBEE728。 你有兩個選擇：

1. 將其保留為 string 並使用 JSON.parse()，如下所示：

    var request = new XMLHttpRequest(); request.open('GET', 'https://au2mailer.com/api/a2m-getschemaorg.asp?apikey=fe9fc289c3ff0af142b6d3bead98a923'); request.send(); request.onload = ()=>{ let res = JSON.parse(request.response); document.getElementById("a2mjson").innerHTML = res; }

2. 在 ASP 中更改您的響應 header（推薦）：在此處查看此答案： 如何在經典 ASP 中返回 JSON object
