javascript中將Object轉換為String函數代碼(jsonstr)_javascript技巧

代碼如下:
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?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;ir.push(obj2str(o[i]))
r="["+r.join()+"]"
}
return r;
}
return o.toString();
}
