JSON.stringify源码（在看extend文档的时候看到）
var object1 = { apple: 0, banana: {weight: 52, price: 100}, cherry: 97 }; var object2 = { banana: {price: 200}, durian: 100 }; /* object2 合并到 object1 中 */ $.extend(object1, object2); var printObj = typeof JSON != "undefined" ? JSON.stringify : function(obj) { var arr = []; $.each(obj, function(key, val) { var next = key + ": "; next += $.isPlainObject(val) ? printObj(val) : val; arr.push( next ); }); return "{ " + arr.join(", ") + " }"; }; $("#log").append( printObj(object1) ); })转载于:https://www.cnblogs.com/pengfei25/p/8202597.html
