label 属性名称 text .

鉴于:

[
  {
    "value": "45a8",
    "label": "45A8",
    "children": [
      {
        "value": "45a8.ba08",
        "label": "BA08",
        "children": [
          {
            "value": "45a8.ba08.45a8",
            "label": "45A8"
          }
        ],
        "checked": false
      }
    ]
  },
  ...
]

需要:

[
  {
    "value": "45a8",
    "text": "45A8",
    "children": [
      {
        "value": "45a8.ba08",
        "text": "BA08",
        "children": [
          {
            "value": "45a8.ba08.45a8",
            "text": "45A8"
          }
        ],
        "checked": false
      }
    ]
  },
  ...
]

您可以首先用 JSON.stringify() JSON.parse() :

var data = [
  {
    "value": "45a8",
    "label": "45A8",
    "children": [
      {
        "value": "45a8.ba08",
        "label": "BA08",
        "children": [
          {
            "value": "45a8.ba08.45a8",
            "label": "45A8"
          }
        ],
        "checked": false
      }
    ]
  }
];

data = JSON.parse(JSON.stringify(data).replaceAll('"label"', '"text"'));
console.log(data);

更新:

var data = [
  {
    "value": "45a8",
    "label": "45A8",
    "children": [
      {
        "value": "45a8.ba08",
        "label": "BA08",
        "children": [
          {
            "value": "45a8.ba08.45a8",
            "label": "45A8"
          }
        ],
        "checked": false
      }
    ]
  }
];
var find = '"label"';
var re = new RegExp(find, 'g');
data = JSON.parse(JSON.stringify(data).replace(re, '"text"'));
console.log(data);

也可以使用 recursion . 可能是这样的:

const nestArr=[ { "value": "45a8", "label": "45A8", "children": [ { "value": "45a8.ba08", "label": "BA08", "children": [ { "value": "45a8.ba08.45a8", "label": "45A8" } ], "checked": false } ] }];

changeLabelToText=arr=>{
    return arr.map(({label,...rest})=>{
      if(rest.children) rest.children = changeLabelToText(rest.children);
      return {text:label, ...rest}
    })
};

console.log(changeLabelToText(nestArr));

let data = [
  {
    "value": "45a8",
    "label": "45A8",
    "children": [
      {
        "value": "45a8.ba08",
        "label": "BA08",
        "children": [
          {
            "value": "45a8.ba08.45a8",
            "label": "45A8"
          }
        ],
        "checked": false
      }
    ]
  }
]

for (const key in data.keys()){
  if(key === "label"){
    object.text = object[key]
    delete object.key
  }
}
