即时更新珊瑚礁部分
我开始深入挖掘珊瑚礁，我磕磕绊绊，我真的不知道如何解决......
我有一个RETextField和一个REButton，我希望按下按钮时文本字段的内容会更新，所以这就是我正在尝试的内容：
initializeContents
self
add:
((RETextField new)
id: 'myTextField';
on: #textFieldContents of: self).
self
add:
((REButton new)
label: 'Try me!';
callback: [
self triggerThenDo: [
textFieldContents := textFieldContents , ' and something else']).
initializeContents
self
add:
((RETextField new)
id: 'myTextField';
on: #textFieldContents of: self).
self
add:
((REButton new)
label: 'Try me!';
callback: [
self triggerThenDo: [
textFieldContents := textFieldContents , ' and something else'.
(self canvas jQuery: '#myTextField')
load html:
[ :h | h text: textFieldContents ] ] ])
self canvas jQuery ajax script: etc.
