Separate submit buttons on forms which tell form “action” to post to different files?

由 前提是你 提交于 2019-12-09 23:33:53
问题 I have included an additional Submit button within my form which I am going to use like so. User selects item User hits "Add another item" Submit button on form. Form POSTS to itself and reloads the page so user can add another item Once user has added several items the user hits "Finished" Submit button. The form posts to another file with all the accumulated items. I have a uneasy feeling that this might not be achievable with PHP/HTML alone and that I might have to use some Javascript to

Struts2学习笔记(2)值传递

由 本小妞迷上赌 提交于 2019-12-09 20:37:08
Struts2中的传值实现 1.action接收jsp传过来的值: a.定义一个User类 有name pwd属性, 添加相应的get，set方法 b.<!-- 方式1 普通java类 --> 在UserAction中 添加: private User user; 并添加相应的get,set方法 <!-- 方式2 实现ModelDriven<T>接口--> 在UserAction中 @Override public User getModel() { return user; } <!--方式3 在UserAction中 直接写属性> private String name; private String pwd; public String methodxxx() { User user=new User(); ...xxx; } 注意：表单里面name定义的方式，根据name更改Action中方法的判断方式 c.jsp界面中添加form表单 (方式1) jsp中input 属性中name="user.name"这么写框架就会自动new user();所以Action不能用user是否为空判断 <form action="User_register" method="post"> <label style="color:red;">${errorMsg }</label><br/

JSF2: action and actionListener

由 六眼飞鱼酱① 提交于 2019-12-09 19:36:52
问题 From this answer by BalusC here Differences between action and actionListener, Use actionListener if you want have a hook before the real business action get executed, e.g. to log it, and/or to set an additional property (by <f:setPropertyActionListener>, . However when I decide to write some code to test this, the result is a bit different. Here is my small code <h:form id="form"> <h:panelGroup id="mygroup"> <p:dataTable id="mytable" value="#{viewBean.foodList}" var="item"> <p:column> #{item

问题 My question refers directly to this question. The answer to that question shows how one can create a ViewGroup , embed it inside a WindowManager , and allow the WindowManager to catch MotionEvent s through onTouchEvent(MotionEvent event) .
