模拟表单向domino post大容量的数据

用JS完成POST的过程，由domino数据库的代理接收。以下的JS代码配合后面的JAVA代理修改指定的数据库的指定文档的指定域

function post2Domino() {
 var oFORM = document.createElement("FORM");
 oFORM.method = "POST";
 oFORM.action = S_DbUrl +"/AG_SavePost?openagent&m_seq=" + Math.random();  //AG_SavePost为domino代理
 oFORM = document.body.appendChild(oFORM);
 var postObj = {
  o:oFORM,
  createField:function(_type, _attr, _style) {
      var newField = document.createElement(_type);
      if (_attr) {
          for (var k in _attr) {
              if (k == 'class') newField.className = _attr[k];
              else if (k == 'id') newField.id = _attr[k];
              else newField.setAttribute(k, _attr[k]);
          }
      }
      if (_style) { for (var k in _style) newField.style[k] = _style[k]; }
      return this.o.appendChild(newField);
  },
  submit:function() {
   this.o.submit();
  }
 };
 postObj.createField("input",        /*指定文档ID*/
  {name:'F_DocID',value:'<计算的值>'},
  {display:'none'}
 );
 postObj.createField("input",       /*指定所在数据库path*/
  {name:'F_DBPath',value:'<计算的值>'},
  {display:'none'}
 );
 postObj.createField("input",     /*完成之后返回的URL*/
  {name:'F_ReturnPath',value:'<计算的值>'},
  {display:'none'}
 );
 postObj.createField("textarea",
  {name:'F_ReviewLogRTF',value:document.all.eventtab1.innerHTML},
  {display:'none'}
 );
 postObj.createField("textarea",
  {name:'F_ReviewLogRTFS',value:document.all.eventtab2.innerHTML},
  {display:'none'}
 );
 postObj.submit();
}

以下是AG_SavePost代理的内容：该代理通过getDocumentContext得到POST过来的文档，从文档中的域request_content得到JS POST过来的数据，request_content域里面内容大概是这样的： F_DocID=XXXXXX&F_DBPath=XXXXXXXX&F_ReturnPath=XXXXX&F_ReviewLogRTF=XXXXX......... 

这里用到URLDecoder类对这里面的内容进行解码。 通过传过来的F_DBPath和F_DocID找到要修改的文档，然后修改它的F_ReviewLogRTF域....
