如何将JavaScript对象作为数组进行访问

Question

在GopherJS中，对象的成员本身就是对象(就像js在幕后处理事情一样)。

因此，当访问成员时，会返回一个*js.Object

func makeRID(o *js.Object) string {
  // access the array of numbers in member RID:
  arr := o.Get("RID")
  // arr is now a *js.Object - not an []interface{} - which is what I actually need (and what the contents of the property RID really are...
}

传入的o是从服务器的JSON响应中提取的js对象。它的成员"RID“是字节值的数组-例如{ RID: [ 136, 210, 92, 97, 152, 26, 17, 233, 147, 147, 8, 0, 39, 223, 163, 7 ], ...

我没有在谷歌上搜索，也没有在gopherjs的js文档中看到任何明确的指示，说明如何从*js.Object转到与js数组等效的gopherjs，即[]interface{}

想法？

*js.Object -> []interface{}

哇-呼-明白了！感谢您的建议:)

func makeRID(o *js.Object) string {
  // access the array of numbers in member RID:
  jsRID := o.Get("RID")
  // I know that the source object's RID member is an Array, so we can access it in gopherjs as:
  jsArray := jsRID.Interface().([]interface{})
  // ... profit!
}
