defines what classes DWR can create and remote for use by Javascript
Bean类必须都有一个默认的无参构造器
DWR has a few restrictions:
Avoid reserved JavaScript words 
Methods named after reserved words are automatically excluded. Most JavaScript reserved words are also Java reserved words, so you won't be having a method called "try()" anyway. However the most common gotcha is "delete()", which has special meaning from JavaScript but not Java. 
Overloaded methods can be involved in a bit of a lottery as to which gets called, so avoid overloaded methods. 


 

换了个方法来处理读入的xml文件
文件:formdatas.xml
<?xml version="1.0" encoding="gb2312"?>
<formdatas>
  <data>
   <address>地址</address>                                    #text
   <productaddress>生产地址</productaddress>   #text
   <diploma>大专</diploma>                                  #select
   <type>二类|四类|三类</type>                           #checkbox
   <sex>女</sex>                                                   #radio
   <date>2005年12月31日</date>                        #text
   <memo>备注</memo>                                      #textarea   
   </data>  
</formdatas>
js片段:
function updateform(xmlname,obj){  
 var url = ""+xmlname;

 if(document.implementation&&document.implementation.createDocument) {
  
  var xmldoc = document.implementation.createDocument("", "", null);
  xmldoc.onload =  handler(xmldoc, obj);
  xmldoc.load(url);
 }
 else if(window.ActiveXObject) {
  
  var xmldoc = new ActiveXObject("Microsoft.XMLDOM");
  xmldoc.onreadystatechange = function() {
   if(xmldoc.readyState == 4) handler(xmldoc, obj);
  }
  xmldoc.load(url);
 }
}

function handler(xmldoc, obj) {
 var formdatas = xmldoc.getElementsByTagName("data")[0]; 
 for (var i=0;i<obj.length ;i++ ){
   e=obj[i];     
   if (e.name != '') //表单中的e.name对应xml里的tagName,利用对应关系,将值写入表单中
   {    
    if ( e.type == 'text' || e.type == 'textarea'){     
     e.value = formdatas.getElementsByTagName(e.name)[0].firstChild.data;   
    }
    if( e.type == 'checkbox' || e.type == 'radio'){
     var temp = formdatas.getElementsByTagName(e.name)[0].firstChild.data.split("|");     
     for(var k=0; k<temp.length; k++){
      //alert( temp[k] );
      if( e.value == temp[k] ) e.checked = true;
     }
    }
    if( e.type == 'select-one' ){
     var selvalue = formdatas.getElementsByTagName(e.name)[0].firstChild.data;
     document.getElementById(e.name+"div").innerHTML="";
     document.getElementById(e.name+"div").innerHTML=selvalue;
    }

   }
 }
}
效果:点击"读取xml文件"按钮,将相应的值解析到文本框中,如下所示:
