javascript - 将 json 转换为嵌套的 JavaScript 对象

Question

我有一个 json int 文件，其中包含如下任何项目:

输入JSON

{
    "action.button.submit": "Submit"
    "action.button.submitting": "Submitting"
    "buttons.common.add": "Add"
    "buttons.common.reset": "Reset"
    "constants.bom.conditional.or.mandatory.conditional": "Conditional"
    "constants.bom.conditional.or.mandatory.mandatory": "Mandatory"
}

输出

{
   action: {
       button: {
           submit: 'Submit'
           submitting: 'Submitting'
       }
   },
   buttons: {
       common: {
           add: 'Add',
           reset: 'Reset'
       }
   },
   constants: {
      bom: {
         conditional: { 
            or: {
                mandatory:{
                   conditional: 'Conditional',
                   mandatory: 'Mandatory'
               }
            }
         }
      }
   }
}

这是我所能得到的:

newData = {};
Object.keys(data).forEach(item => {
    const splitData = item.split('.');
    splitData.forEach((detail, index) => {
        if(index === 0 && !newData[detail]) newData[detail] = {};
    })
});
console.info(newData)

我想采用Input并使其看起来像output

您必须递归深入遍历结果对象:

function parse(obj) {
  const root = {};

  for(const [key, value] of Object.entries(obj)) {
    const parts = key.split(".");
    const parent = parts.slice(0, -1).reduce((acc, part) => acc[part] || (acc[part] = {}), root);
    parent[parts.pop()] = value;
  }

  return root;
}
