另一个，你的json里，键怎么可以用数字啊，这样无法用对象调用的

如上图片，遍历pserise对象，所以第一步需要先得到pserise对象，是个数组，再对该数组遍历

用递归遍历,代码如下，将你的JSON对象，转换层JSON字符串 alert(jsonToStr(carData)) 

function jsonToStr(json){
	if(json instanceof Array){ //如果是数组
		var tmpArr = [];
		for(var i=0;i<json.length;i++){
			tmpArr.push(jsonToStr(json[i])); //递归
		}
		return '['+tmpArr.join(",")+']'; //如果json是数组，那么最终会return这个
	}else if(json instanceof Object){ //如果是对象
		var tmpArr = [];
		for(var n in json){
			tmpArr.push('"'+n+'":'+jsonToStr(json[n])); //递归
		}
		return '{'+tmpArr.join(",")+'}'; //如果json是对象，那么最终会return这个
	}else if(typeof json == 'string'){ //如果是字符串
		return '"'+json.replace(/(\\|\")/g,"\\$1").replace(/\n/g,"\\n")+'"'; //如果json是字符串，就过滤掉斜杠、双引号、换行再返回
	}else{
		return json; //否则就原样返回
	}
}

结构都知道，用[]或者.取数据就行了，由于你的有些键名称不是javascript的合法变量名称，所有要用[]来取

用for in 来遍历 for(var name in carData) { alert(name+":"+carData[name]); }
json字符串递归解析
在这个例子中，`recursiveParse`函数首先尝试使用`JSON.parse()`解析输入的JSON字符串。如果解析结果是对象且不是数组，那么遍历每个属性，如果属性的值仍然是一个对象，就递归调用`recursiveParse`函数。如果解析...
Python实现深度优先搜索文件夹
这个简单的DFS实现会遍历`root_dir`及其所有子文件夹中的所有文件，并打印出文件名。你可以根据需求修改此代码，例如增加过滤条件只处理特定类型的文件，或者收集满足条件的文件信息到一个列表中。 在Python中，DFS...
