小编Pir*_*ada的帖子

有人告诉我我们使用这些的区别和例子.我知道它的NULL值.

我有SSL的MVC3应用程序.我想要特定的页面URL应该总是添加Https.有人能告诉我怎么做.以下是全局文件中的路径.

 routes.MapRoute("root22",
                "paybill",
                new { controller = "Home", action = "PayBill" });

还有一件事,如果我的URL前面有https而不是页面中的所有路径也使用https或不需要？

很烦人.不知道为什么会出现这个错误.在下面的代码中

NOTE:

if I only use <td>${user.id}</td> than its printing id properly but on ${user.username} property generating error. See below JSP page code.

If I use below code in JSP page like to test than I get all the objects and properties


<c:forEach var="user" items="${users}" varStatus="i">
    <tr>
        <td>${users[i.index]}</td>
    </tr>                       
</c:forEach>

Result:

User[id=1,username=u1,password=p1,firstname=f1,lastname=l1,dob=2012-07-01,age=40]
User[id=2,username=u2,password=p2,firstname=f2,lastname=l2,dob=2012-07-02,age=39]
User[id=3,username=u3,password=p3,firstname=f3,lastname=l3,dob=2012-07-03,age=38]

错误:

09:49:49,047 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/crud_jsp_servlet_cdi_jdbc_tagfile].[jsp]] (http-localhost-127.0.0.1-8080-1) Servlet.service() for servlet jsp threw exception: javax.el.PropertyNotFoundException: The class 'com.myapp.dao.User' does not have the property 'username'.

有人告诉我.submit()vs:submit之间的区别.何时何地使用简单的例子请.

谢谢

这是JSON返回的

var errorsObject = JSON.parse('{ "fieldErrors": {"name":["You must enter your name1"],"name":["You must enter your name2"],"age":["Only people ages 13 to 19 may take this quiz"]}}');

下面的代码第一个循环工作正常,我得到名称,年龄等关键名称.在第二个循环中想要获取从外循环中选择的键的值.Issue is errors.fieldErrors[key].我需要首先只使用名称循环键并获得2个值.

$.each(errors.fieldErrors, function(key, val) {
    alert("key->" + key); //Fine
    $.each(errors.fieldErrors[key], function(index, val) {
        alert("key->" + key + ", val->" + val);
    });
});
