JSF-DataTableへのデータの追加
このセクションでは、dataTableに行を追加する方法を紹介します。
応用例
上記の機能をテストするためのテストJSFアプリケーションを作成しましょう。
Step | Description |
---|---|
1 | Create a project with a name helloworld under a package com.finddevguides.test as explained in the JSF - Display DataTable sub-chapter of JSF - DataTables chapter. |
2 | Modify home.xhtml as explained below. Keep the rest of the files unchanged. |
3 | Compile and run the application to make sure the business logic is working as per the requirements. |
4 | Finally, build the application in the form of war file and deploy it in Apache Tomcat Webserver. |
5 | Launch your web application using appropriate URL as explained below in the last step. |
home.xhtml
<?xml version = "1.0" encoding = "UTF-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns = "http://www.w3.org/1999/xhtml"
xmlns:h = "http://java.sun.com/jsf/html"
xmlns:f = "http://java.sun.com/jsf/core">
<h:head>
<title>JSF tutorial</title>
<h:outputStylesheet library = "css" name = "styles.css" />
</h:head>
<h:body>
<h2>DataTable Example</h2>
<h:form>
<h:dataTable value = "#{userData.employees}" var = "employee"
styleClass = "employeeTable"
headerClass = "employeeTableHeader"
rowClasses = "employeeTableOddRow,employeeTableEvenRow">
<h:column>
<f:facet name = "header">Name</f:facet>
#{employee.name}
</h:column>
<h:column>
<f:facet name = "header">Department</f:facet>
#{employee.department}
</h:column>
<h:column>
<f:facet name = "header">Age</f:facet>
#{employee.age}
</h:column>
<h:column>
<f:facet name = "header">Salary</f:facet>
#{employee.salary}
</h:column>
</h:dataTable>
<h3>Add Employee</h3>
<hr/>
<table>
<tr>
<td>Name :</td>
<td><h:inputText size = "10" value = "#{userData.name}"/></td>
</tr>
<tr>
<td>Department :</td>
<td><h:inputText size = "20" value = "#{userData.dept}"/></td>
</tr>
<tr>
<td>Age :</td>
<td><h:inputText size = "5" value = "#{userData.age}"/></td>
</tr>
<tr>
<td>Salary :</td>
<td><h:inputText size = "5" value = "#{userData.salary}"/></td>
</tr>
<tr>
<td> </td>
<td><h:commandButton value = "Add Employee"
action = "#{userData.addEmployee}"/></td>
</tr>
</table>
</h:form>
</h:body>
</html>
すべての変更を完了したら、JSF-最初のアプリケーションの章で行ったようにアプリケーションをコンパイルして実行します。 すべてがアプリケーションで問題ない場合、次の結果が生成されます。
Add Employee Formに値を追加し、_Add Employee_ボタンをクリックします。 次の結果を参照してください。
