如何使用特定键访问该结构的映射中的结构字段值

Question

I have "FormError" struct. I pass this struct to my template. So how to access InputError struct field value with specific key in the template?

type InputError struct {
    Val string
    Has bool
}

type FormError struct {
    Errs map[string]InputError
}

This doesn't work.

<input name="Name" type="text" value="{{index .Errs.Val `Name`}}">

Answer 1

Use {{.Errs.Name.Val}}. There's no need to use index.
