推荐答案

JSON格式只是一个字符串.因此，您可以使用关联的方法来处理JSON字符串. JSON.

JSON format is merely a String in javascript's point of view. So you could manipulate the JSON string with associated method. JSON.

// The original
obj = {
  children: [
    {
        name:'Basic Ext Layouts',
        expanded: false,
        children:[
        {
            name:'Absolute',
            id:'absolute',
            leaf:true,
        }]
    }]
}

// Transfer the object to a JSON string
var jsonstr = JSON.stringify(obj);

// HERE you do the transform
var new_jsonstr = jsonstr.replace('"children"', '"mydata"');

// You probably want to parse the altered string later
var new_obj = JSON.parse(new_jsonstr);
