英特尔XDK的ListView排序 [英] Intel XDK listview sort

问题描述

我试图让与英特尔XDK和Parse.com一个简单的应用程序作为后端服务。

I try to make a simple application with Intel XDK and Parse.com as backend service.

我做了如此列表视图教程显示。

ListView控件，在我的应用程序，显示在底部的最新项。代替的，我想显示与相反的方式列表。 - 在列表顶部的最新的条目

The listview, in my app, displays the newest entries at the bottom. Instead of that i want to show the list with the opposite way - the most recent entries at the top of the list.

在一个简单的HTML5的JS文件我做到这一点与 query.ascending（createdAt）;在Parse.com在文档中描述的JavaScript 。我怎么能与英特尔XDK愿意这样做？

In a simple HTML5-JS file i do it with query.ascending("createdAt"); as described in documentation for JavaScript in Parse.com. How i can do it so with Intel XDK?

我将AP preciate每一个乐于助人的答案。

I will appreciate every helpfull answer.

修改克里斯 - 帕金斯的第一个答案后

EDIT after the first answer from Chris Perkins

我设法我Parse.com数据库英特尔XDK外部Web服务按照整合<一个href=\"http://stackoverflow.com/questions/25630215/intel-xdk-parse-com-integration-unauthorized/25650442#25650442\">this回答。

I managed to integrate my Parse.com database in Intel XDK as external web service according to this answer.

所以，在----- / WWW / XDK /服务/服务methods.js，通过我的服务调用的方法的一部分，是这样的：

So, in -----/www/xdk/services/service-methods.js, the part of method invoked by my service looks like this:

intel.xdk.services.iodocs_.New_Service = ((function (credentials) {
  var exports = {};

    exports.ServiceObject = function(params) {
    var url = 'https://api.parse.com/1/classes/ServiceObject';
    return $.ajax({
            url : url,
            headers : {
            'X-Parse-Application-Id' : credentials.apiKey,
            'X-Parse-REST-API-Key' : credentials.apiSecret
            }
        });
    };

  return exports;
}))(intel.xdk.services.credentials.New_Service,intel.xdk.services.iodocs_.helpers);

如果我有正确理解，我要反向显示阵列是我服务的回应身体的成果的价值，这一切都是 VAR出口的大括号内= { }; 。我正确与否？

If I have understood correctly the array that i want to display reversely is the value of the "results" in the Respond Body of my service and all this is within the curly brackets of var exports = {};. I am right or not?

推荐答案

我尝试了上述建议是什么，但甚至没有创建的列表。

I tried what suggested above, but the list was not even created.

的解决方案是不是数据库与应用程序相关联的方式。

The solution was not the way the database associated with the application.

我意识到，在一个模板和解决方案在于Backbone.js的文件中创建列表。所以，我打开了----- / WWW / JS / backbone_support.js，并试图通过做一些类似的

I realized that the list is created in a template and that the solution lies in the backbone.js file. So, i opened the -----/www/js/backbone_support.js and tried to intervene by doing something similar to this

var myCollection = Backbone.Collection.extend({
        model: myModel,
        comparator: function(item) {
            return -item.get('');
        }
    });

或想找个地方一个符合这样的事情

or to find somewhere a line with something like this

$（'＃名单）追加（listItem.render（）EL）; 并修改 .append（）到。prePEND（）。

没有什么帮助了我。但最终我发现在code的那些行

Nothing helped me. But eventually I noticed those lines in the code

//non-destructive reverse
var nd_reverse = function(arr){ return _.initial(arr, 0).reverse(); };

我删除了 .reverse（）和它发生了。现在，列表显示在顶部我Parse.com数据库的最新作品。

I deleted the .reverse() and it happened. Now the list displays the newest entries of my Parse.com database at the top.

我不知道这是否是propper的解决方案，或者如果它是适用于更复杂的问题，但我希望能帮助弄好了。

I don't know if this is the propper solution or if it is suitable for more complex issues but i hope to help somehow.
