I am trying to trigger a get for a table based on a response header

我正在尝试根据响应头触发表的GET

<table class="table">
  <thead>
    <tr>
      <th>Tasks</th>
      <th>Date</th>
      <th>Complete</th>
      <th></th>
    </tr>
  </thead>
  <tbody id="todo-table" hx-get="http://localhost:8081/data" hx-trigger="todoAdded from:body">
  </tbody>
</table>

func SubmitTodo(w http.ResponseWriter, r *http.Request) {
    http.Header.Add(w.Header(), "Access-Control-Allow-Methods", "*")
    http.Header.Add(w.Header(), "Access-Control-Allow-Origin", "*")
    http.Header.Add(w.Header(), "Access-Control-Allow-Headers", "*")

    // Stop here if its Preflighted OPTIONS request
    if r.Method == "OPTIONS" {
        return
    }

    // Get the value from the form field
    value := r.FormValue("todo")
    if value == "" {
        return
    }

    todoList = append(todoList, todoTask{Task: value, Done: false, InputtedDate: time.Now()})
    fmt.Println(value)

    w.Header().Set("HX-Trigger", "todoAdded")

    // Respond with an "ok" message and set the HX-Trigger header
    w.WriteHeader(http.StatusOK)
    w.Write([]byte("ok"))
}

I can see the header is set in the response but no get event is fired. If I replace "todoAdded" with "load" the get request does fire.

我可以看到在响应中设置了标头，但没有触发任何GET事件。如果我将“todoAdded”替换为“Load”，GET请求就会触发。

I think what you're doing is that you are submitting a form, not through AJAX, but with a full page submit. I believe that the HX-Trigger header will then not be acted upon. Try adding hx-boost to the form in order to turn the submit into an htmx AJAX request and see if the header then works.

我认为你正在做的是，你提交一个表单，而不是通过AJAX，但与一个完整的页面提交。我相信HX-Trigger头将不会被执行。尝试将hx-boost添加到表单中，以便将提交转换为htmx AJAX请求，并查看头部是否正常工作。

The docs for the HX-Trigger response headers says:

HX-Trigger响应头的文档如下：

These response headers can be used to trigger client side actions on the target element within a response to htmx.

If you are doing a normal form submit, then you are adding the header to a response to the page, not a response to htmx.

如果您正在执行普通的表单提交，那么您将标题添加到对页面的响应，而不是对htmx的响应。
