JS将Array数组转化为轻量级JSON对象

//将Array数组转化为Json

function arrayToJson(o) {

var r = [];

if (typeof o == "string") return "\"" + o.replace(/([\'\")/g]\\])/g, "\\$1").replace(/(\n)/g, "\\n").replace(/(\r)/g, "\\r").replace(/(\t)/g,
"\\t") + "\"";

if (typeof o == "object") {

if (!o.sort) {

for (var i in o)

r.push(i + ":" + arrayToJson(o[i]));

if (!!document.all && !/^\n?function\s*toString\(\)\s*\{\n?\s*\[native code\]\n?\s*\}\n?\s*$/.test(o.toString)) {

r.push("toString:" + o.toString.toString());

}

r = "{" + r.join() + "}";

} else {

for (var i = 0; i < o.length; i++) {

r.push(arrayToJson(o[i]));

}

r = "[" + r.join() + "]";

}

return r;

}

return o.toString();

}
