提问by Ankur Ankan
I am trying to use data extracted from a XML file by getElementByTagNameand it returns HTML Collection Objectbut I need this data for a sending a REST request so I need to get the HTML Collection Object to be converted into a string. How can it be done?
我正在尝试使用从 XML 文件中提取的数据getElementByTagName并返回，HTML Collection Object但我需要此数据来发送 REST 请求，因此我需要将 HTML 集合对象转换为字符串。怎么做到呢？
Here's more information:
以下是更多信息：
com_zimbra_om.prototype._responseHandler=
function(response){
try{
sid = response.xml.getElementsByTagName("session_id");
this.login_user();
}catch(e){
this._showErrorMsg(e);
}
Using this function I am trying to get the session_idfrom a REST response. Here sid(global variable) is the HTML Collection Object. Now when I try to use this in the next function:
使用此函数，我试图session_id从 REST 响应中获取。这里sid（全局变量）是 HTML 集合对象。现在，当我尝试在下一个函数中使用它时：
com_zimbra_om.prototype.login_user = function(){
var url = selected_server + 'services/UserService/loginUser?SID=' +
sid + '&username='+
selected_username +
'&userpass=' +
selected_password;
var request_url = ZmZimletBase.PROXY + AjxStringUtil.urlComponentEncode(url);
So here I am using sidwhich I need as a string.
所以在这里我使用sid我需要的字符串。
So how should I convert HTML Collection Object into string??
