如何删除掉数组中的某一项？

Question

数组的结构是这样的：[{"title":123,"num":1,"type":[{"name":A,"num":1},{"name":B,"num":1},{"name":C,"num":0}]},{"title":321,"num":1,"type":[{"name":D,"num":0},{"name":E,"num":1},{"name":F,"num":0}]}]请问怎么样可以删除掉type中num=0的对象，其他num=1的继续保留？网上搜到的基本都是指定位置来删的，不适合使用。

Answer 1

就是这样
vararray=[
{
"title":123,
"num":1,
"type":[{"name":'A',"num":1},{"name":'B',"num":1},{"name":'C',"num":0}]
},{
"title":321,
"num":1,
"type":[{"name":'D',"num":0},{"name":'E',"num":1},{"name":'F',"num":0}]
}];
array.forEach(function(x){
x.type=x.type.filter(function(y){
returny.num!=0;
});
});
                            

Answer 2

可以用.filter函数来删除，比如
a=[{"name":'A',"num":1},{"name":'B',"num":1},{"name":'C',"num":0}]
b=a.filter(function(x){returnx.num!=0})
