我已经读过NetBeans默认是客户端.我刚遇到一个问题,我在我的应用程序中有很多bean,并且<param-value>设置为客户端,所以我得到了
java.io.NotSerializableException
错误,虽然我的bean是Serializable(即他们实现了Serializable接口.).我的豆子在@ViewScope中.但是当我把它改成服务器时,事情就会起作用.为什么?使用客户端和服务器时有什么区别.任何人都可以借助一个例子来解释我.
谢谢
如果我有一个迭代器并且我想检查最后一个值,我该如何检查它?喜欢
private Set<String> saarcCountries = new TreeSet<String>();
Iterator iter = saarcCountries.iterator();
while(iter.hasNext()) {
String name = (String)iter.next();
int countryId = Integer.parseInt(name);
newsOrAnnouncementInsert.add(newsId);
newsOrAnnouncementInsert.add(countryId);
newsOrAnnouncementInsert.add(1); //addby
if (!(last value in iterator))) {
newsOrAnnouncementInsert.add("~!~");//Delimiter for Multiple Detail Records
}//end if
} //end of while

我想阻止用户在达到最大字符限制时在textarea中输入文本.发生了什么,当我达到最大限制然后我的文本区域滚动条移动到顶部我以某种方式阻止这个代码.
jQuery(document).ready(function($) {
$('textarea.max').keyup(function() {
var $textarea = $(this);
var max = 400;
if ($textarea.val().length > max) {
var top = $textarea.scrollTop();
$textarea.val($textarea.val().substr(0, max));
$textarea.scrollTop(top);
}
});
}); //end if ready(fn)

但我也希望在达到最大限制后用户无法在textarea中输入任何内容.目前发生的情况是,如果用户按住键,达到最大限制后,字符在文本区域中键入,虽然在释放按钮后它返回到原始文本(即$ textarea.val($ textarea.val()). substr(0,max));).但是,一旦这种情况成为现实,我希望这样
if ($textarea.val().length > max) {
