对函数参数进行循环

    gr:{"path":data.gr.path,"name":data.gr.name}}
 });

如您所见，我只是将所有元素列为数据。所以，我的问题是：我可以对数据进行循环以使其只有一行完全相同吗？那怎么办呢，因为元素是vectorMap函数的一个参数。

预先感谢您的帮助。

Answer 1

要更简单地创建此数据结构，您可以遍历 data 中的键并构建所需的对象数组，如下所示：

var options = {
  width: 950,
  height: 550,
  paths: {}
};
for (var key in data) {
  options.paths[key] = {
    path: data[key].path,
    name: data[key].name
  }
}
$.fn.vectorMap('addMap', 'world', options);

Answer 2

您可以使用 Object.assign 和 Object.entries 在一个表达式中执行此操作：

"paths": Object.assign(...Object.entries(data).map( ([k,v]) => ({ [k]: v }) ))

但是请注意，这将注入整个 data.xx 对象，包括它们可能具有的除 path 和 name 之外的任何其他属性。如果这是不需要的，那么：

"paths": Object.assign(...Object.entries(data).map(
    ([k, {path,name}]) => ({ [k]: {path, name} }) 
))
