ExtJS 5.1構建錯誤（Yui Parse錯誤）

Question

我使用eclipse進行ExtJS開發，我在eclipse中使用ant build，它使用Sencha cmd。 我的項目詳情是

app.framework.version = 5.1.0.107

app.cmd.version = 5.1.0.26

當我嘗試構建項目時，它失敗了Yui Parse錯誤，但我在工作區中找不到任何錯誤。你能解釋一下堆棧跟蹤消息嗎？

Answer 1

我打算走出去，建議這是因為你在你的房產名稱中使用了一個保留字 。 雖然它在javascript中通常是“好的”並且你的ExtJS應用程序在開發模式下運行，但我發現在縮小這些關鍵字的YUI扼流圈時。

最簡單（也可能是可取的）選項只是為了避免保留關鍵字和名稱抽象其他東西，例如abstractObj 。 如果你想強制解決問題，你可以改為：

if(!Propca.view.abstract) // ...

...嘗試數組訪問表示法：

if(!Propca.view['abstract']) // ... 

...或者在錯誤消息中的if語句的特定情況下， in運算符：

if(!('abstract' in Propca.view)) // ...

在這些情況下（以及您可能擁有的任何其他情況）使用關鍵字作為字符串訪問該屬性似乎滿足編譯器 - 雖然它違反了約定並且看起來不是很整潔所以可能不值得...

Answer 2

您的JavaScript中存在語法錯誤; 當它組合成一個文件時，YUI壓縮器無法處理它和barfs。

不幸的是，ExtJS沒有很好的工具來識別單個文件中的錯誤。 您可以嘗試使用其他工具（例如，我使用jshint作為預構建Ant任務），或者您只需查看自上次成功構建以來已更改的文件並將其縮小。
