（Handlebarsjs模板）如何从外部JSON源获取数据？ [英] (Handlebarsjs templating) How to get data from external JSON source?

问题描述

请参阅此链接： http://jsfiddle.net/Rousnay/FJzre/ 它正在工作，JSON数据将通过 http://json.virtuecenter.com/json-data/blogs/tags?callback=？

但它不工作，当我想要从 http://sunday-theater-club.simpletix.eu/API/ThemeUIHandler.asmx/GetMenuItems?callback=？

任何人都可以通过 jsfiddle 示例来帮助我。 返回的数据对模板无效，从 http://sunday-theater-club.simpletix.eu/API/ThemeUIHandler.asmx/GetMenuItems?callback = 的？你最终得到：

  [
 {
text：Home，
url：/Default.aspx
}，
 {
text：Events，
url：/ Event-List /
}，
 {
text：Test，
url：/ Pages / 8276 / Test /
} 
] 
  

当从 http://json.virtuecenter.com/json-data/blogs/tags?callback= ？您有：

  {
blogsTags：[
 {
tag： GovernorBentley，
count：1，
separation_path：\ / blogs\ / byTag\ / GovernorBentley.html
}，
 {
tag：Huntsville，
count：1，
separation_path：\ / blogs\ / byTag\ / Huntsville.html
} ，
 {
tag：投票责任，
count：1，
separation_path：\ / blogs\ / byTag\ / Voting Responsibility.html
，
 {
tag：投票权，
count：1，
separation_path： \ / blogs \ / byTag \ / Voting Rights.html
} 
]，
分页：{
限制：20，
total：4，
page：1，
pageCount：1 
} 
} 
  

您的模板需要一个blogsTags属性。

See this link: http://jsfiddle.net/Rousnay/FJzre/ it is working, the JSON data come trough http://json.virtuecenter.com/json-data/blogs/tags?callback=?

but it is not working when i want to get data from http://sunday-theater-club.simpletix.eu/API/ThemeUIHandler.asmx/GetMenuItems?callback=?

Can anyone help me with jsfiddle example. please.

解决方案

The returned data is not valid to the template, when getting from "http://sunday-theater-club.simpletix.eu/API/ThemeUIHandler.asmx/GetMenuItems?callback=?" you end up with:

[
    {
        "text": "Home ",
        "url": "/Default.aspx" 
    },
    {
        "text": "Events ",
        "url": "/Event-List/"
    },
    {
        "text": "Test",
        "url": "/Pages/8276/Test/"
    }
]

and when getting from "http://json.virtuecenter.com/json-data/blogs/tags?callback=?" you have:

{
    "blogsTags": [
                     {
                         "tag":"GovernorBentley",
                         "count":1,
                         "separation_path":"\/blogs\/byTag\/GovernorBentley.html"
                     },
                     {
                         "tag":"Huntsville",
                         "count":1,
                         "separation_path":"\/blogs\/byTag\/Huntsville.html"
                     },
                     {
                         "tag":"Voting Responsibility",
                         "count":1,
                         "separation_path":"\/blogs\/byTag\/Voting Responsibility.html"
                     },
                     {
                         "tag":"Voting Rights",
                         "count":1,
                         "separation_path":"\/blogs\/byTag\/Voting Rights.html"
                     }
                 ],
                 "pagination": {
                     "limit":20,
                     "total":4,
                     "page":1,
                     "pageCount":1
                 }
}

your template expects a "blogsTags" property.
