Front-end and back-end parsing and conversion of json

1. Java parses json 4 ways:
(1) json-lib
(2) Jackson
(3) Gson
(4) FastJson

2, js (conversion methods supported by browsers (Firefox, chrome, opera, safari, ie9, ie8) Wait for browsers: )
JSON.parse(jsonstr); //Can convert json string into json object
JSON.stringify(jsonobj); //Can convert json object into json string

3, jquery
$.ajax({
type : "POST",
        data: {"templateId":templateId},
        dataType: "json",
url: "/msip_dj/template/editTemplateLayout",
success: function(data) {

if(null != data){
$(" .demo").html(decodeURIComponent(data.templateEditStr).replace(/\+/g, ' ').replace(/\\/g, '\\\\'));
}
        }
});

tempTemplateEditStr = URLEncoder.encode(template.getTemplateEditStr(), "UTF-8");
