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);
