javascript将一对象(包括数组、JSON、function)转换成字符串

 

    function obj2Str(obj){  
    switch(typeof(obj)){  
       case 'object':  
        var ret = [];  
        if (obj instanceof Array){  
         for (var i = 0, len = obj.length; i < len; i++){  
          ret.push(obj2Str(obj[i]));  
         }  
         return '[' + ret.join(',') + ']';  
        }  
        else if (obj instanceof RegExp){  
         return obj.toString();  
        }  
        else{  
         for (var a in obj){  
          ret.push(a + ':' + obj2Str(obj[a]));  
         }  
         return '{' + ret.join(',') + '}';  
        }  
       case 'function':  
        return 'function() {}';  
       case 'number':  
        return obj.toString();  
       case 'string':  
        return "\"" + obj.replace(/(\\|\")/g, "\\$1").replace(/\n|\r|\t/g, function(a) {return ("\n"==a)?"\\n":("\r"==a)?"\\r":("\t"==a)?"\\t":"";}) + "\"";  
       case 'boolean':  
        return obj.toString();  
       default:  
        return obj.toString();  
    }  
    }
