Md_ajaxdeal.java接口使用流程 if (mddele.equals(action) ) mddele即为相应操作按钮的itemname名称Map map = (HashMap) request.getSession().getServletContext().getAttribute(Global.SYSCODE_KEY);MDCol mdCol =MDManager.getacol(mdname, map);String p_id = stringpara.getpara(p_id); 在p_id中取相应的参数if(htgl_gl_col.equals(mdname) 如果“htgl_gl_col”与mdname相匹配则继续运行，否则的话else if运行String ht_bh = stringpara.getpara(ht_bh);在“ht_bh”中提取相应的参数ContractManage cm = new ContractManage(ht_bh);创建 ContractManage类的对象returninfo = cm.delContract(); cm对象调用delContract()方法else if(htgl_fygl_col.equals(mdname)String ht_bh = stringpara.getpara(ht_bh);String fy_bh = stringpara.getpara(fy_bh);OutlayManage om = new OutlayManage(ht_bh,fy_bh);returninfo = om.delOutlay();else if(pc_xx_col.equals(mdname)/进行判断，该批次下是否有物料信息/根据p_id找到对应的批次，再查找该批次下是否有对应的物料信息String pc_bh = stringpara.getpara(pc_bh);PCManager bh = new PCManager(pc_bh); if(bh.hasInfo()returninfo = 该批次下有物料信息，无法删除！;elsereturninfo = mdCol.mddele(p_id);else if(dbpc_xx_col.equals(mdname)String pc_bh = stringpara.getpara(pc_bh);PCManager bh = new PCManager(pc_bh);if(bh.hasInfo()returninfo = 该批次下有物料信息，无法删除！;elsereturninfo = mdCol.mddele(p_id);else if(sxpc_xx_col.equals(mdname)String pc_bh = stringpara.getpara(pc_bh);PCManager bh = new PCManager(pc_bh);if(bh.hasInfo()returninfo = 该批次下有物料信息，无法删除！;elsereturninfo = mdCol.mddele(p_id);
