json找到所有children

在JavaScript中,JSON是一種常見的數(shù)據(jù)格式,它非常適合在前端和后端之間進(jìn)行數(shù)據(jù)交換。如果需要在JSON數(shù)據(jù)中找到所有的children,可以使用如下的代碼:

let data = {
"name": "parent",
"children": [
{
"name": "child1",
"children": [
{
"name": "grandchild1"
},
{
"name": "grandchild2"
}
]
},
{
"name": "child2",
"children": [
{
"name": "grandchild3"
},
{
"name": "grandchild4"
}
]
}
]
};
function findChildren(obj) {
let children = [];
if (obj.children) {
children = children.concat(obj.children);
obj.children.forEach(function(child) {
children = children.concat(findChildren(child));
});
}
return children;
}
let allChildren = findChildren(data);
console.log(allChildren);

以上代碼會(huì)輸出所有的children,包括nested的children。在代碼中,我們定義了一個(gè)findChildren的函數(shù),它會(huì)遞歸地遍歷每個(gè)對(duì)象,如果這個(gè)對(duì)象有children屬性,則將children屬性的值加入到children數(shù)組中,然后對(duì)children屬性的每個(gè)元素遞歸調(diào)用findChildren函數(shù),將結(jié)果合并到最終的children數(shù)組中。
