Appfuse: Adding custom page Components

I used to do ASP, and when I came across a similar component that was used by multiple pages, I wanted to use the ascx (user-defined component) to solve it, and that's what I wanted to do with Java.

The effect I have to do is as follows:

Implementation scenario: Tag mode (custom label)

1. First define your own tag

1<%@ tag body-content= "scriptless" pageencoding= "UTF-8"%>2<%@ attribute name= "table" required= "true"%>3<%@ attribute Name= "IDfield" required= "true"%>4<%@ taglib uri= "http://java.sun.com/jsp/jstl/fmt" prefix= "FMT"%>5<%@ taglib uri= "Http://java.sun.com/jsp/jstl/core" prefix= "C"%>6<c:set var= "base" value= "${pagecontext.request.contextpath}"/>7<c:set var= "Typelist"/>8<script src= "<c:url value="/scripts/jquery/jquery.1.10.2.min.js "/>" ></script>9<form method= "POST" >Ten<div id= "Divrecomment" > One<fmt:message key= "Recomment.title"/> A&nbsp;&nbsp; -<select id= "recommendaction" name= "Recommendaction" > -<c:foreach items= "${recommenttype}" var= "T" > the<option value= "${t.key}" >${t.value}</option> -</c:forEach> -<select> -&nbsp;&nbsp; <input type= "button" onclick= "handlerecomment ();" +Value= ' <fmt:message key= "recomment.submit"/> 'class= "Btn btn-primary"/> -</div> +</form>

Recommend.tag

2. Using a custom Label

<%@ taglib prefix= "T" tagdir= "/web-inf/tags"%>

<t:recommend table= "" idfield= "" ></t:recommend>

3. Recommenttype Data Source: Use the HandleRequest in the controller that corresponds to the page

1 New Hashmap<string,string>(); 2         Recommenttype.put ("1", "Home");   3         Recommenttype.put ("2", "other");    4         Request.setattribute (Constants.recomment_type, Recommenttype);

HandleRequest

Styles attached to

1 #divRecomment {2    margin-left:12px;  3 }4#divRecomment Select{5    width:200px;  6    height:38px;  7    border:1px solid #cccccc;  8 }
