由 允我心安 提交于 2020-01-14 14:02:27
问题 I want to create an action in a Rails controller that does something in the db and then just refreshes the current page. Example: Controller: A Views: A, B. controller A is the following: def action1 somethingToTheDB end view A is the following: -html- -body--link to action 1--/body- -/html- view B is the following -html- -body--link to action 1--/body- -/html- If I come to action 1 from view A I want to refresh view A, if I come from view 2 I want to refresh view 2. Is that possible without

Accessing Action class in JSP using Struts2

问题 Does anyone know how to easily access the Action class in a JSP when using Struts2? While I know it is often possible to use Struts tags and OGNL, I actually find them both to be confusing (clearly due to ignorance) and quite frankly find it easier to maintain Java in the JSP (not to mention it's easier to explain to new programmers as everyone knows Java). I have searched for a solutions for years, and the best solution I have found is to call a static method from a class, that looks like:

UrlHelper.Action(“Edit”, “Ad”) returns id parameter?

问题 Hi, I am using the following code to generate a URL : UrlHelper urlHelper = new UrlHelper(htmlHelper.ViewContext.RequestContext); urlHelper.Action("Edit", "Ad"); If Im currently is on URL http://localhost:16055/Ad/Edit/87 the Action method will return : "/Ad/Edit/87" ? Why? I thought that urlHelper.Action("Edit", "Ad") would in this satet not include any parameters? BestRegards Edit 1: (routs) routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "

How can I achieve it? 回答1: You can use the valueChangeListener attribute, pointing to a method in the managed-bean and add a submit() in the onchange attribute. The form should look like :

Ext.Ajax.request与form.submit的用法区别

由 眉间皱痕 提交于 2020-01-11 04:56:38
相同点：都属于Ajax提交方式！ 不同点：Ext.Ajax.request是Ext.data.connection的一个实例 form1.getForm().submit是BasicForm的一个实现方式 使用上的区别： 1.form1.getForm().submit常用在表单提交的时候，就是说要提交页面数据，比如新增和修改数据页面 2.Ext.Ajax.request常用在根据参数提交的时候，比如删除，我们把页面选中的ID进行遍历，封装在一个Array中，作为一个参数做Ajax的提交 例子： 首先是form1.getForm().submit的例子： function formSubmit(){ if (form1.getForm().isValid()) { form1.getForm().submit({ waitTitle : '提示' , //标题 waitMsg : '正在提交数据请稍后...' , //提示信息 url : 'eidtBooktype.action' , method : 'post' , params : 'booktype' , success : function (form, action) { var flag=action.result.msg; window.returnValue= 'SUCC' ; Ext.Msg.alert(

Java Action Listeners in a different class not working

由 时间秒杀一切 提交于 2020-01-06 19:45:33
问题 I've been working with JFrame recently and had a simple login, register and popup frames work when I had them in a single class. I wanted to make it nicer and not all packed inside one class so I made a class for the frames, buttons, panels, variables and the main class. My problem is that The frames themselves are working fine and loading up and displaying, but the ActionListeners on the buttons aren't working at all. Nothing changes when I hit a button etc. I'm fairly new to Java and very
