在javascript中将[object HTMLCollection]转换为字符串 [英] converting a [object HTMLCollection] into string in javascript

问题描述

我尝试使用由 getElementByTagName 从XML文件中提取的数据，并且它返回 HTML集合对象，但是我需要这些数据来发送REST请求，所以我需要将HTML Collection Object转换为字符串。如何做？

以下是更多信息：

  com_zimbra_om .prototype._responseHandler = 
函数（响应）{
尝试{
 sid = response.xml.getElementsByTagName（session_id）; 
 this.login_user（）; 
} catch（e）{
 this._showErrorMsg（e）; 
} 
  

使用这个函数我试图得到 session_id 来自REST响应。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_pa​​ssword; 
 var request_url = ZmZimletBase.PROXY + AjxStringUtil.urlComponentEncode（url）; 
  

所以我在这里使用 sid 需要作为字符串。

那么我应该如何将HTML集合对象转换为字符串？

谢谢

解决方案

有了这些信息，我只能跟着

  var objectHTMLCollection = document.getElementsByTagName（div），
 string = [] .map.call（objectHTMLCollection，function（node）{
 return node.textContent || node.innerText ||; 
}）。join（）; 
  

I am trying to use data extracted from a XML file by getElementByTagName and it returns HTML Collection Object but 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?

Here's more information:

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_id from a REST response. Here sid (global variable) is the HTML Collection Object. Now when I try to use this in the next function:

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 sid which I need as a string.

So how should I convert HTML Collection Object into string??

Thanks

解决方案

With this information I can only go with

var objectHTMLCollection = document.getElementsByTagName("div"),
    string = [].map.call( objectHTMLCollection, function(node){
        return node.textContent || node.innerText || "";
    }).join("");
