jquery easyui dataGrid 和struts2结合使用小例子

jquery easyui dataGrid 和struts2结合使用小例子

很高兴又步入到jquery easyui的学习中，说实话我喜欢web开发......

java代码：

Student类:

public class Student {
private String id;
private String name;
private String className;
public String getId() {
return id;
}
public String getName() {
return name;
}
public String getClassName() {
return className;
}
public void setId(String id) {
this.id = id;
}
public void setName(String name) {
this.name = name;
}
public void setClassName(String className) {
this.className = className;
}

}

Action代码:

EasyuiAction类:

package org.easyui;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import com.opensymphony.xwork2.ActionSupport;

public class EasyuiAction extends ActionSupport{
private static final long serialVersionUID = 1L;
private static int Num = 10;
private int total;
private List<Object> rows;

public int getTotal() {
return total;
}
public void setTotal(int total) {
this.total = total;
}
public List<Object> getRows() {
return rows;
}
public void setRows(List<Object> rows) {
this.rows = rows;
}
@Override
public String execute() throws Exception {
this.total = 100;
this.rows = new ArrayList<Object>();
for(int i=0;i<Num;i++){
Studentstudent = new Student();
student.setId("id_"+i);
student.setName("name_"+i);
student.setClassName("className_"+i);

Map<String,Object> map = new HashMap<String,Object>();
map.put("id", student.getId());
map.put("name", student.getName());
map.put("className",student.getClassName());

this.rows.add(map);
}
return SUCCESS;
}

}

struts.xml文件的配置如下：

easyDemo.jsp页面代码:

String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

easyDemo.js代码如下:用ajax做测试json格式的数据.

var xmlhttp;
function verify(){
//创建XMLHttpRequest对象
if(window.XMLHttpRequest){
xmlhttp = new XMLHttpRequest();
if(xmlhttp.overrideMimeType){
xmlhttp.overrideMimeType("text/xml");
}
}else if(window.ActiveXObject){
var activerxName = ["MSXML2.XMLHTTP","Microsoft.XMLHTTP"];
for(var i=0;i<activerxName.length;i++){
try{
xmlhttp = new ActiveXObject(activerxName[i]);
break;
}catch(e){
}
}
}
//确认XMLHttpRequest对象是否创建成功
if(!xmlhttp){
alert("XMLHttpRequest对象创建失败");
return;
}else{
}
xmlhttp.onreadystatechange = callback;
xmlhttp.open("POST","easyAction.action","true");
xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xmlhttp.send(null);
}
function callback(){
if(xmlhttp.readyState == 4){
if(xmlhttp.status == 200){
var oBook = eval('(' + xmlhttp.responseText + ')');//普通的字符串转变成具体的对象的时候
// alert(xmlhttp.responseText);
$.messager.alert('test jsonData',xmlhttp.responseText);
/* var bookHolder = document.getElementById('bookHolder');
var sBook = '<p><b>ISBN: </b>' + oBook.ISBN + '</p>';
sBook += ('<p><b>Title: </b>' + oBook.title + '</p>');
sBook += ('<p><b>Price: </b>$' + oBook.price + '</p>');
sBook += ('<p><b>date: </b>' + oBook.date + '</p>');
sBook += ('<b><i>Comments: </i></b><hr/>');
for(i = 0; i < oBook.comments.length; i++) {
sBook += ('<p><b>#' + (i + 1) + ' </b>' + oBook.comments[i] + '</p>');
}
bookHolder.innerHTML = sBook;

}
}
}
