[Json] How to decode json

本文記錄json中文編碼/解碼的問題
如果要將編輯過的json中文字串，只要將\取代成%，再使用javascript的unescape function就可以解碼。

var encodejson = "\u8521\u5927\u75E3";
encodejson = encodejson.replace("\\","%");
document.write("json decode :" + unescape(encodejson) + "
");

var test = "蔡大痣";
document.write("test:" + test + "
");
document.write("to edcode from test:" + escape(test) + "
");
document.write("to decode from test:" + unescape(test) + "
");

輸出：

json decode :蔡大痣
test:蔡大痣
to edcode from test:%u8521%u5927%u75E3
to decode from test:蔡大痣
