我接受@LastCoder的建议，并编写了一个简单的实现。它似乎在做我想要的事情。
var jsonDates = {
dtrx2: /\d{4}-\d{2}-\d{2}/,
parse: function(obj){
var parsedObj = JSON.parse(obj);
return this.parseDates(parsedObj);
},
parseDates: function(obj){
// iterate properties
for(pName in obj){
// make sure the property is 'truthy'
if (obj[pName]){
var value = obj[pName];
// determine if the property is an array
if (Array.isArray(value)){
for(var ii = 0; ii < value.length; ii++){
this.parseDates(value[ii]);
}
}
// determine if the property is an object
else if (typeof(value) == "object"){
this.parseDates(value);
}
// determine if the property is a string containing a date
else if (typeof(value) == "string" && this.dtrx2.test(value)){
// parse and replace
obj[pName] = new Date(obj[pName]);
}
}
}
return obj;
}
};
