当我在文本字段中编辑文本时，NavigationLink会激活

Question

every time I edit textfield, getSearchResult is called. what should I do to call getSearchResult only when I press Search button?

part of Contentview:

NavigationLink(destination: SearchResultList(text: setQuery(text))){
    TextField("text~", text: $text)
    Text("Search")
}

part of SearchResultList:

struct SearchResultList: View {
    @State var text: String
    @State var result = Result(sSearchResult: getSearchResult(query: query) as! SearchResult)

    var body: some View {

    }
}

Searching data every time when textfield changes causes severe speed problem

Answer 1

Don't include TextField in the NavigationLink 's content. Following code should work for you:

HStack {
    TextField("text~", text: $text)
    NavigationLink(destination: DetailsView(tech: techCollection[0])){
        Text("Search")
    }
}
