1. Create a SOAP request and invoke the caller. ref:Simplest SOAP example

2. Get the response and parse the XML. ref:Parse XML using JavaScript

1. 创建一个 SOAP 请求并调用调用者。 参考：最简单的 SOAP 示例

2. 获取响应并解析 XML。 参考：使用 JavaScript 解析 XML

Here a possible approach, assuming you put wsdl into a file request.wsdland assuming that the remote server is accessible and have Access-Control-Allow-Origin: *header

这是一种可能的方法，假设您将 wsdl 放入文件request.wsdl并假设远程服务器可访问并具有Access-Control-Allow-Origin: *标头

//wsdl request
var client = new XMLHttpRequest();
client.open('GET', 'request.wsdl');
client.onreadystatechange = function () {
  var request = client.responseText;//here the wsdl

        //SOAP request
        var client2 = new XMLHttpRequest();
        client2.open('POST', 'http://83.212.96.238:8080/DgesvSampleWs/DgesvSampleWsService', true);

        client2.onreadystatechange = function () {
          if (client2.readyState == 4) {
            if (client2.status == 200) {
              console.log(client.responseText);//here the response
            }
          }
        }
        client2.setRequestHeader('Content-Type', 'text/xml');
        client2.send(request);
}

client.send();

The idea is performing and ajax to call wsdl definitions and in it's callback, perform another ajax that call that you want to call. This domains http://83.212.96.238:808it's not giving me response but I think the approach is valid.

这个想法是执行和 ajax 调用 wsdl 定义，并在它的回调中执行另一个你想要调用的调用的 ajax。这个域http://83.212.96.238:808它没有给我回应，但我认为这种方法是有效的。
