我有一些奇怪的步骤。我在头部渲染阶段呈现了ajax行为
final AbstractDefaultAjaxBehavior behave = new AbstractDefaultAjaxBehavior() {
protected void respond(final AjaxRequestTarget target) {
boolean undoEn = getRequest().getQueryParameters().getParameterValue("undoEn").toBoolean();
if (undoEn) {
mSaveButton.setEnabled(true);
target.add(mSaveButton);
}
}
};
public String getCallbackName() {
return "saveButtonVisibilityToggle";
}
@Override
public void renderHead(IHeaderResponse response) {
String script = getCallbackName() + " = function (e) { Wicket.Ajax.ajax({\"u\": \"" + behave.getCallbackUrl() + " + &undoEn=\"+e+\"\" });}";
response.render(OnDomReadyHeaderItem.forScript(script));
}
这一切都运行良好,每次在tinyMCE编辑器中更改节点时都会调用此行为
settings.addCustomSetting(" setup: function(editor) {" +
" editor.on('NodeChange', function(e) {" +
" editor.save();" +
getCallbackName() + "(editor.undoManager.hasUndo())" +
" });" +
" }");
但有时当我离开浏览器标签时,更改几个标签(chrome)然后使用其他应用程序几分钟,然后转回我们的标签,ajax网址意外出现在浏览器网址中。
http://localhost:8080/wicket/bookmarkable/com.tac.kulik.pages.SomePage?3-1.IBehaviorListener.0-contentPanel&entityId=2+++&undoEn=true
这也很奇怪,相反,normap参数传递了它的++++符号
顺便说一句,这个叹息被认为是“2”,所以出于某种原因'+'变成了空白更新1 使用@svenmeier回答我的页面启动无限循环刷新。与日志
org.apache.wicket.core.request.mapper.StalePageException: A request to
page '[Page class = x.x.x.CardPage, id = 25, render count = 1]' has been
made with stale 'renderCount'. The page will be re-rendered.
并且由于某种原因,表现为链接有renderCount 1,但表单有0。 来自浏览器的请求 jquery-1.12.4-ver-1476216952000.js:10254 XHR完成加载:GET“http://localhost:8080/wicket/bookmarkable/com.tac.pages.ca ...?4-0.IBehaviorListener.0-contentPanel& cardId = 1& _ = 1476873175645& undoEn = true”
我添加了一些JS以防止cicling刷新,但我仍然有Stale异常
"if (editor.undoManager.hasUndo()) { " +
" console.debug('Behave called ');" +
behave.getCallbackScript() +
" }" +
这是我的举止
final AbstractDefaultAjaxBehavior behave = new AbstractDefaultAjaxBehavior() {
protected void respond(final AjaxRequestTarget target) {
log.info("Behave called");
boolean undoEn = getRequest().getQueryParameters().getParameterValue("undoEn").toBoolean();
if (undoEn) {
mSaveButton.setEnabled(true);
target.add(mSaveButton);
}
}
//
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes attributes) {
super.updateAjaxAttributes(attributes);
String undoEn = "return {'undoEn': editor.undoManager.hasUndo()};";
attributes.getDynamicExtraParameters().add(undoEn);
}
};
并没有区别,它可以表现得没有任何实现,页面行为相同((
final AbstractDefaultAjaxBehavior behave = new AbstractDefaultAjaxBehavior() {
@Override
protected void respond(AjaxRequestTarget target) {
}
};
答案 0 :(得分:2)
您应该重新设计行为以使用动态额外参数。
@Override
protected void updateAjaxAttributes(AjaxRequestAttributes attributes)
{
super.updateAjaxAttributes(attributes);
String undoEn = "return {'undoEn': editor.undoManager.hasUndo()}";
attributes.getDynamicExtraParameters().add(undoEn);
}
和
settings.addCustomSetting(
"setup: function(editor) {" +
" editor.on('NodeChange', function(e) {" +
" editor.save();" +
" " + getCallbackScript() + ";" +
" });" +
"}");
