為什么回調沒有被執行？

Question

我正在編寫一個基本的Web應用程序（從海邊開始），但回調從未運行......任何想法？

renderContentOn: html

  | group |
  html form: [

    html text: 'Gender: '.
    group := html radioGroup.
    group radioButton
        selected: self contact isMale;
        callback: [ self contact beMale ].
    html text: 'Male'.
    group radioButton
        selected: self contact isFemale;
        callback: [ self contact beFemale ].
    html text: 'Female'.
    html break.

    html anchor
    callback: [ mmpiItems setAnswer: (self option) ];
    with: 'Next'.
 ]

Answer 1

表單內的錨點不提交表單，只提交提交按鈕。 這不是由Seaside定義的，而是由HTML定義的。

您可以在海邊書中找到有關海邊書寫表格的更多信息： http ： //book.seaside.st/book/fundamentals/forms

Answer 2

您必須使用submitButton而不是anchor或任何其他button 。

您的代碼如下所示：

renderContentOn: html

 | group |
 html form: [
   html text: 'Gender: '.
   group := html radioGroup.
   group radioButton
     selected: self contact isMale;
     callback: [ self contact beMale ].
   html text: 'Male'.
   group radioButton
     selected: self contact isFemale;
     callback: [ self contact beFemale ].
   html text: 'Female'.
   html break.
   "Use a submitButton instead of a regular anchor/button"
   html submitButton
     callback: [ mmpiItems setAnswer: (self option) ];
     with: 'Next'.
   ]
