JQuery set value for the json: path provided as string

问题

I have a string that carry the path of a nested json, where I need to update a value

var path = 'p_Data[0]["BusinessUnit"][0]["BusinessUnit"]' 

if i evaluate this path I get value as 'Unit1'. I need to update the value 'Unit1' with 'Closed' and retrieve the original data ie, p_Data

I tried eval(path = 'Closed'), but didn't work.

How to do this?

回答1:

eval(path + "='Closed'");

But have a look at this thread: Why is using the JavaScript eval function a bad idea?.
