common2.js代碼：

function getOddsData() { 
     oddsHttp.open("get", "vbsxml/goalBf3.xml?r=007" + Date.parse(new Date()), false); 
     oddsHttp.setRequestHeader("User-Agent", ""); 
     oddsHttp.send(null); 
     var root = oddsHttp.responseXML.documentElement.childNodes[0];

oddsHttp作爲XMLHttpRequest的

我懷疑跨域問題導致「無法讀取屬性」childNodes「」

我想修改y JS通過以下方法

public WebResponse getResponse(WebRequest request) throws IOException { 
    if(request.getUrl().toExternalForm().contains("common2.js")){ 
.... 
    } 
}

如何解決？

這不是一個跨域問題，警告：內容是不是在序言允許的關鍵

我用下面的代碼

new WebConnectionWrapper(wc) { 
         public WebResponse getResponse(WebRequest request) throws IOException { 
           WebResponse response = super.getResponse(request); 

           if(request.getUrl().toExternalForm().contains("goalBf3.xml")){ 
            System.out.println(response.getContentAsString("UTF-8")); 
            String content = response.getContentAsString("UTF-8"); 
             if(null != content && !"".equals(content)){ 
              if(content.indexOf("<") != -1 && content.lastIndexOf(">") != -1 && content.lastIndexOf(">") > content.indexOf("<")) 
               content = content.substring(content.indexOf("<"), content.lastIndexOf(">") + 1); 
             } 

            WebResponseData data = new WebResponseData(content.getBytes("UTF-8"), 
               response.getStatusCode(), response.getStatusMessage(), response.getResponseHeaders()); 
             response = new WebResponse(data, request, response.getLoadTime()); 
           } 
           return response; 
          } 
        }
