javascript和web服务WSDL

我想使用javascript调用web服务。我有一个表单，其中我给出了一些参数（int），并希望得到结果。如何使用javascript实现

下面是WSDL文件

第二个呢

创建SOAP请求并调用调用方。 ref:

获取响应并解析XML。 ref:

这里是一种可能的方法，假设您将wsdl放入文件

request.wsdl

，并假设远程服务器是可访问的，并且具有

访问控制允许源：

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();

其思想是执行和ajax来调用wsdl定义，并在其回调中执行另一个您想要调用的ajax调用。此域

它没有给我回应，但我认为这种方法是有效的
