Question

当我尝试解析下面的JSON内容时，我得到了这个异常

SyntaxError: Unexpected token T in JSON at position 236
    at JSON.parse (<anonymous>)
    at AppComponent.populatePivotGrid (app.component.js:18)

JSon内容：

	  var test = JSON.parse(temp);//it breaks here with the above mentioned exception/error

此JSON内容有什么问题？

Answer 1

您需要使用双\来转义引号。

所以代替：... return \"Total Rtlr Name\"; ...

将其写为：... return \\\"Total Rtlr Name\\\"; ...

希望有所帮助。

SyntaxError：位于JSON中的意外标记T.
