Com*_*eOn 5 java wicket wicket-6
我有检票口AutoCompleteTextField。为了更新模型，我使用“onblur”事件。我需要在“onblur”事件发生后刷新文本字段，因为需要验证。
这是说明问题的代码示例
网页子类：
public class TestPage extends WebPage {
private Integer testField;
public TestPage() {
final List<Integer> allowedValues = new ArrayList<Integer>();
for (int i = 0; i < 5; i++) {
allowedValues.add(50 + i * 5);
}
final PropertyModel<Integer> testModel = new PropertyModel<Integer>(this, "testField");
final AutoCompleteSettings autoCompleteSettings = new AutoCompleteSettings();
autoCompleteSettings.setShowListOnEmptyInput(true);
autoCompleteSettings.setShowListOnFocusGain(true);
final AutoCompleteTextField<Integer> testInput =
new AutoCompleteTextField<Integer>("testInput", testModel, autoCompleteSettings) {
@Override
protected Iterator<Integer> getChoices(final String input) {
return allowedValues.iterator();
}
};
testInput.setOutputMarkupId(true);
testInput.setMarkupId("testInput");
add(testInput);
testInput.add(new AjaxFormComponentUpdatingBehavior("onblur") {
@Override
protected void onUpdate(final AjaxRequestTarget target) {
target.add(testInput);
}
});
}
}
对应的HTML：
<?xml version="1.0" encoding="UTF-8"?>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:wicket="http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd" xml:lang="en"
lang="en">
<body>
<input type="text" wicket:id="testInput"/>
</body>
</html>
问题是无法通过鼠标点击来选择值。
我尝试过使用OnChangeAjaxBehavior- 并且通过鼠标单击进行选择有效，但我不想在每次更改后执行验证（例如用户想要输入 54，他输入 5 => 验证开始，因为OnChangeAjaxBehavior被触发）
我尝试过使用两者的组合 AjaxFormComponentUpdatingBehavior("onblur")，并且OnChangeAjaxBehavior遇到了同样的问题：无法通过鼠标单击选择值，因为“onblur”在“onchange”之前触发
请注意，如果您注释该行target.add(testInput);，它将按预期工作。
这似乎与这个 Wicket问题类似
它说该问题已在 6.18.0 版本中修复，但我使用的是 Wicket 6.18.0，但仍然存在此问题。
我们一直在执行从 Wicket 1.4 到 wicket 6 的升级。在 Wicket 1.4 中它运行良好。
请给我有关如何解决此问题的任何建议。我们将非常感谢您的帮助。提前致谢。
我建议您使用 wicket Jquery UI 自动完成框：
