我想在引导选项卡中添加一个关闭图标,然后我可以通过单击图标关闭选项卡.

我尝试下面,但"X"显示不与标题标题在同一行.

.close {
    font-size: 20px;
    font-weight: bold;
    line-height: 18px;
    color: #000000;
    text-shadow: 0 1px 0 #ffffff;
    opacity: 0.2;
    filter: alpha(opacity=20);
    text-decoration: none;
    display:inline;
}
.close:hover {
    display:inline;
    color: #000000;
    text-decoration: none;
    opacity: 0.4;
    filter: alpha(opacity=40);
    cursor: pointer;
}

<a id="user-list-tab-li" style="display:inline;" href="#user-list-tab-pane">The tab</a> 
<span class="close">×</span>

我正在开发一个必须在1.5运行时环境中部署的项目.那么有谁知道如何使用Intellij IDEA将项目目标构建为1.6乘1.6 JDK,我的开发是Mac OSX 10.8和JDK 1.6

我想在我的项目中使用zeroMQ,然后运行如下的configure来将libaray构建到我的主文件夹中

./configure --enable-static --disable-shared --prefix=/home/xx/out

然后我链接我的项目

gcc -o myproject x.c y.c /home/xx/out/libzmq.a

但仍有很多链接错误,如下所示:

../zmq/lib/libzmq.a(libzmq_la-ip.o): In function zmq::resolve_ip_interface(sockaddr_storage*, unsigned int*, char const*)':
/home/sureone/share/zeromq-2.2.0/src/ip.cpp:221: undefined reference to std::basic_string<char, std::char_traits<char>, std::allocator<char> >::~basic_string()'

我有一个包含按钮的表单，单击按钮时会提交表单，以及如何防止这种情况。例如，我只想在单击按钮时显示“警报”。并将按钮放在表单之外对我来说不是一个选择。

顺便说一句，我使用引导框架。

    <form class="form-inline" role="form" id="form-area">
        <input type="hidden" name="key" value="dept-area">
        <div class="form-group">
            <input type="text" class="form-control" name="data" placeholder="">
        </div>

        <button class="btn btn-default" id="btn-area">test</button>
    </form>

我有一张表"table1"之类的

NAME COL1 COL2 COL3 COL4
A    1    2    3    4

我想通过过滤表

"SELECT * FROM table1 where (COL1=1 OR COL2=1 OR COL3=1 OR COL4=1)"

我希望结果是

NAME COL_NAME
A    COL1

这可能是SQL语句吗？

在"applicationContext-base.xml"中我添加如下:

我想在"控制器"中为一个函数设置一个事务

@Controller
@RequestMapping("/ywdata")
public class YwController  extends BaseController{
....
@Transactional(timeout=1)
private void submitNewSXSQ(Map map, HttpServletRequest request, HttpServletResponse response) throws Exception {

    ...//STEP1 :do some db insert and update STEP1
    if(true)
        throw new Exception("test …

Spring MVC中"ModelAndView.addObject"和"Session.setAttribute"之间有什么区别？

似乎他们都可以共享Object并在JSP中使用.
