extjs嵌套json

從各個位置獲取衝突的信息是否嵌套的json在extjs中可用。 NB使用Sencha架構師可能會使事情複雜...extjs嵌套json

我有一個客戶端json對象正在通過商店/ ajax代理返回。我無法訪問超出第一級的任何內容。

JSON看起來是這樣的：

根據https://stackoverflow.com/a/8318589/183254嵌套JSON不可用。根據https://stackoverflow.com/a/5604594/183254它是可用，但必須在一定的格式。

我做了基於API文檔格式的小測試：

{ 
    results: 2000, 
    rows: [ 
     { id: 1, firstname: 'Bill', occupation: 'Gardener', cool: {neat: 'wow'} }, 
     { id: 2, firstname: 'Ben' , occupation: 'Horticulturalist' }, 
    ] 
}

與此進來，我可以調用一切從一個第三方物流。特別是，cool.neat打印wow。但是，將cool更改爲cool:[{neat:'wow}]休息。所以看起來嵌套json部分工作 - 可能只是部分原因，因爲我做錯了什麼。

我的想法是，對api執行單個請求並收集所有需要的信息，解析它，並將它發送給組件，而不是爲每個需要的數據組創建代理，這樣纔有意義。我可能是錯的...

除了必要的指導/ facepunches我有2個問題：

1）是否有可能/實際嘗試做我在做什麼？即試圖使用單個請求來收集多個組件的數據？

2）有沒有辦法從tpl調試數據？

這是extjs 4.1通過Sencha建築師

我有這個相同的問題。我可以解決這個問題的唯一方法（我嘗試了映射和其他幾個解決方案）基本上都有一個主存儲和多個子存儲。從ajax獲取信息並將其帶入主商店。有一個「加載」監聽器，當它加載時，檢查是否需要將信息傳遞給其他商店。

將所有的substores autoload屬性設置爲false並且永不加載它們。

即：

load: function(t,records,successful,eOpts) { 
    var substores [{store: nameOfStore, root: rootPropInTheJson}, 
        {store...etc...etc..]; 
    for (var i = 0; i < substores.length; i++) { 
     if (pathtoroot* != undefined) { 
      substores[i].store.add(pathtojsonroot) 
     } 
    } 
}

至少，這是我認爲你的意思。如果這就是你的意思，那麼是的，我發現它很實用，我不知道第二個問題的答案。

我假設你有其他的變量集？ 'pathtoroot *'？錯字？無論如何，我總是收到'Uncaught TypeError：Object mySubStore has no method'add''。另外，你可以從主存儲器的構造函數中的加載監聽器調用它。謝謝！ – stormdrain 2013-02-28 20:19:01

隨機變量只是填充。你把var的名字和你的商店放在那裏。如果您正確地做到了這一點，那麼在商店中使用添加變量將只爲其添加記錄。所以你基本上最終確定是否需要添加記錄，然後在需要時將其推出。你可以發佈給你類型錯誤的代碼，以及商店聲明。是的，它是在主店負載監聽器 – 2013-03-01 11:47:08

而*是因爲我打算在底部添加一個註釋，提到根的路徑最終會變成如下形式： t.data.items [i] .raw [substores [I] .root] [j]的。另一件需要注意的事情是，您可能不是尋找根，而是尋找根內的值。也許是一個ID？ t.data.items [0] .raw [substores [i] .root] [j] .id – 2013-03-01 12:10:47
