dwr 的用法

dwr的用法
1.web.xml配置文件配置
<!-- 加载dwr -->
<servlet>
<servlet-name>dwr</servlet-name>
<servlet-class>
org.directwebremoting.servlet.DwrServlet
</servlet-class>
<init-param>
<param-name>debug</param-name>
<param-value>true</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>dwr</servlet-name>
<url-pattern>/dwr/*</url-pattern>
</servlet-mapping>
2.编写dwr配置文件 (在工程下添加一个dwr.xml 文件)
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 2.0//EN" "http://getahead.org/dwr/dwr20.dtd">
<dwr>
<!--allow允许有这样得形式 creator="spring"用spring来管理-->
<allow>
<!--value 是actiin里得路劲 name 是固定得-->
<create javascript="tuserAction" creator="spring">
<param name="beanName" value="tuser"></param> </create>
<convert match="com.accp.ssh.pojo.*" converter="hibernate3">
</convert>


<!--不可以有两个allow的节点 可以有多个 create节点 -->
<create javascript="bidAction" creator="spring">
<param name="beanName" value="bids"></param>
</create>
<convert match="com.accp.ssh.pojo.*" converter="hibernate3">
</convert>
</allow>
</dwr>

3.在 jsp页面导入 js
<script type='text/javascript' src='dwr/interface/bidAction.js'></script>
<script type='text/javascript' src='dwr/engine.js'></script>
<script type='text/javascript' src='dwr/util.js'></script>


4.编写 javaScript代码
如果返回 得是一个 List
<script type="text/javascript">
var dtDivId=1;

function SwitchDisplay(oid){
dtDivId=oid;

var o=document.getElementById(oid);
if (o.style.display =="block")
{
o.style.display = "none";
}
else {
o.style.display = "block";
bidAction.selectBid(dtDivId,seleList);
}
}


var seleList=function(data)
{
if (null!=data && typeof data =='object'){
if (data.length){
var outHtml = "<div>";
for(var i=0;i<data.length;++i){
var bidall = data[i];
outHtml+="<span>拍卖价钱:"+bidall.bidPrice+"</span>" +"</p>"
outHtml+="<span>出价时间:"+bidall.bidTime+"</span>"+" </p>"
outHtml+="<br />";
}
outHtml += "</div>";
var oTable = document.getElementById(dtDivId);
oTable.innerHTML = outHtml;
}else
{
var outHtml = "<div>";
outHtml+="此商品没有任何人出价";
outHtml += "</div>";
var oTable = document.getElementById(dtDivId);
oTable.innerHTML = outHtml;
}
}
}
</script>
<!--动态 生成一个 DIV 并且给他赋值 -->
