javascript 处理null及null值示例

复制代码代码如下:
function dealNull（obj）{
for（var i in obj）{
if（null == obj[i] || "null" == obj[i]）{
obj[i]="";
}else if（"object" == typeof obj[i]）{
dealNull（obj[i]）;
}
}
};
// 测试的对象
var a={};
a.aa=null;
a.bb="null";
a.c=1;
a.b={};
a.b.aaa=null;
a.b.bbb="null";
a.b.c=1;
a.array=[];
a.array.push（{"a":null,"b":"null","c":1}）;
a.array.push（{"a1":null,"b1":"null","c1":1}）;
a.array.push（{"a2":null,"b2":"null","c2":1}）;

dealNull（a）;
