小编And*_*ndy的帖子

我正在尝试设置一个表格,以便每一行都是不同的颜色(奇数/偶数).我有以下CSS:

#woo tr:nth-child(even) td {
    background-color: #f0f9ff;
}

#woo tr:nth-child(odd) td {
    background-color: white;
}

但是,我的一些行可以隐藏,我仍然希望行交替.如何调整上面所以它给出了备用行的外观,即使彼此相邻的行不一定是奇数和偶数？

我很尴尬,我只是失败了一个示例代码,但我会责怪它已经晚了...

我已经复制并粘贴了以下内容:https://developers.google.com/gmail/api/quickstart/quickstart-java 并下载了客户端库:https://code.google.com/p/google-api- java-client / 和https://developers.google.com/api-client-library/java/apis/gmail/v1

当我运行示例时,我得到以下异常:

Exception in thread "main" java.lang.IllegalArgumentException
    at com.google.api.client.repackaged.com.google.common.base.Preconditions.checkArgument(Preconditions.java:76)
    at com.google.api.client.util.Preconditions.checkArgument(Preconditions.java:37)

谷歌搜索,我找不到一个简单的答案,所以假设愚蠢或库缺失/不正确.

我似乎有一个内存泄漏,其中一个罪魁祸首似乎是ConnectionProperty,无论是String,Int还是Boolean.例如:com.mysql.jdbc.ConnectionPropertiesImpl$BooleanConnectionProperty数百万人似乎待在身边而不是GC.

以下是我对DB,Session Factory,Hibernate和Pooling等的设置.:

<bean id="dataSource"
    class="org.springframework.jdbc.datasource.DriverManagerDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver" />
    <property name="url"
        value="jdbc:mysql://${dbHostName}:${database.port}/${database.name}" />
    <property name="username" value="${database.username}" />
    <property name="password" value="${database.password}" />
</bean>
<bean id="txManager"
    class="org.springframework.orm.hibernate3.HibernateTransactionManager">
    <property name="sessionFactory" ref="sessionFactory" />
</bean>
<aop:config>
            <aop:pointcut id="pcut" expression="execution(* com.package.data..*.*(..))"/>
    <aop:advisor advice-ref="txAdvice" ref="pcut" />

        <tx:method name="*" propagation="REQUIRED" />

我有一个表,通常我使用这个选择器来应用奇数和偶数行:

table.find('tbody tr:even').addClass('even');
table.find('tbody tr:odd').removeClass('even');

我的表有各行插入的行,因此我从奇数行中删除它.

我现在隐藏了某些行

jQueryTrObject.hide();

我想要应用与以前相同的样式,以便备用行,就用户而言被标记为奇数和偶数,并且我希望它考虑到隐藏的行.

我如何编写选择器来执行此操作,因为我必须使用每个选项并专门检查吗？

我没有遇到什么问题,只是想着事情.

如果我有一个Web应用程序,让我们调用一个servlet.如果servlet调用调用数据库层的数据管理器.让我们假设其中一个级别会引发异常.有没有一种方法可以识别堆栈顶部存在的会话ID,而不会将表达式一直冒到顶层并进入servlet层？

希望这是有道理的....:o)
