写另一个范围内的变量？

I am newbie in Golang, and I get stuck with setting value of variable from anonymous function (another scope). Now I am using goquery.

For example I've following:

models := []model.User{}

doc.Find(".ff").Each(func(i int, s *goquery.Selection) {
     //...

    models := append(models, model.User{})
})

And this does not work. How can I append new model to models?

:= declares and initializes a new variable, while = assigns to an existing variable.

So change your code to

models = append(models, model.User{})
