GWT 和 GQuery 中的表单提交事件导致 IncompatibleRemoteServiceException。该项目包括用于调用表单提交的 GQuery(JQuery 的 GWT 版本)。这是它的代码。该事件被插入到 onmoduleload 函数中:
$("#search_form").submit(new Function(){
public void f() {
QueryRequest query = new QueryRequest();
String keywords = $("#keyword_search_box").val();
query.setKeywords(keywords);
greetingService.search(query, new AsyncCallback<QueryResponse>() {
@Override
public void onFailure(Throwable caught) {
Window.alert(COUNLDNT_REACH_SERVER);
}
@Override
public void onSuccess(QueryResponse result) {
$("#page").add(renderResponse(result));
}
});
}
});
每当单击提交按钮时,就会出现异常。如果服务器调用是从提交事件之外进行的,它可以正常工作 - 否则执行 public void onFailure(Throwable catch)。这是一个例外:
