Question

我在Array下面。

[{
    "text": "test",
    "subheader": "Production",
    "enabled": false,
    "nodes": [{
        "text": "test",
        "subheader": "JP",
        "enabled": false,
        "nodes": [{
            "text": "test",
            "subheader": "test Operations",
            "enabled": true,
            "nodes": [{
                "text": "test",
                "subheader": "test Operations",
                "enabled": false,
                "nodes": [{
                    "text": "test",
                    "subheader": "test Operations",
                    "enabled": true
                }]
            }]
        }]
    }, {
        "text": "test",
        "subheader": "Planning JP",
        "enabled": false,
        "nodes": [{
            "text": "test",
            "subheader": "test Operations",
            "enabled": false,
            "nodes": [{
                "text": "test",
                "subheader": "test Operations",
                "enabled": true
            }]
        }]
    }, {
        "text": "test",
        "subheader": "india",
        "enabled": false
    }, {
        "text": "test",
        "subheader": "Sales Office, South East Japan",
        "enabled": false
    }, {
        "text": "test",
        "subheader": "Partner Sales JP",
        "enabled": false
    }]
}]

如果看到此数组块。

"nodes": [{
            "text": "test",
            "subheader": "test Operations",
            "enabled": true
        }]

上面的数组代码块将动态添加，并且可能添加n次。现在，我只想在整个数组中将 enabled true更改为false

有人可以帮助我进行代码循环，并将完整结构中的启用值更改为false吗？

Answer 1

我知道这是一个很糟糕的问题，但这是将ALL enabled：false更改为true的一种真正简单的方法

let arr = [{ "text": "test", "subheader": "Production", "enabled": false, "nodes": [{ "text": "test", "subheader": "JP", "enabled": false, "nodes": [{ "text": "test", "subheader": "test Operations", "enabled": true, "nodes": [{ "text": "test", "subheader": "test Operations", "enabled": false, "nodes": [{ "text": "test", "subheader": "test Operations", "enabled": true }] }] }] }, { "text": "test", "subheader": "Planning JP", "enabled": false, "nodes": [{ "text": "test", "subheader": "test Operations", "enabled": false, "nodes": [{ "text": "test", "subheader": "test Operations", "enabled": true }] }] }, { "text": "test", "subheader": "india", "enabled": false }, { "text": "test", "subheader": "Sales Office, South East Japan", "enabled": false }, { "text": "test", "subheader": "Partner Sales JP", "enabled": false }] }]

arr = JSON.parse(JSON.stringify(arr).replace(/"enabled"\:false/g,'"enabled":true'))
console.log(arr)

Answer 2

您可以简单地使用地图功能：

let data={
     "nodes": [{
            "text": "test",
            "subheader": "test Operations",
            "enabled": true
        }]
 }


  data.nodes.map((node)=>Object.assign(node,{enabled:false}))
