复制代码 代码如下:

function obj2str(o){

var r = [];

if(typeof o =="string") return """+o.replace(/(['"])/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+":"+obj2str(o[i]));

if(!!document.all && !/^n?functions*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(obj2str(o[i]))

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

}

return r;

}

return o.toString();

}
