Question

好的，所以我很困惑为什么我正在构建的字符串“神奇地”添加了额外的字符。

首先，我看到了立即窗口中出现的反斜杠：

"[{\"ID\":\"1\",\"F1\":\"lala\",\"F2\":\"hehe\"},{\"ID\":\"2\",\"F1\":\"abc\",\"F2\":\"def\"}]"

但是在Google上看到这些只是“视觉”，并且实际上并不存在于变量值本身时，我尝试了Visualizer文本：

[{"ID":"1","F1":"lala","F2":"hehe"},{"ID":"2","F1":"abc","F2":"def"}]

..好吧，他们不在那里：）

然后我会从Chrome浏览器调用webservce：

{"JSONsampleResult":"[{\"ID\":\"1\",\"F1\":\"lala\",\"F2\":\"hehe\"},{\"ID\":\"2\",\"F1\":\"abc\",\"F2\":\"def\"}]"}

所以不仅反斜杠在那里，而且还在我的方括号周围添加了引号！？

请请有人解释为什么我不能解析一个简单的字符串？什么是添加所有这些额外的东西？
