<div id="datagrid1" url="/inventoryIn.do?method=list"  class="mini-datagrid" 

style="width:100%;height:100%;" pageSize="10" showPageInfo="true" multiSelect="true" >

表明每次load調用    inventoryIn.do?method=list  

表明 InventoryInController中的 list方法

例一：更改搜索條件

 

1.開始日期查詢

<div id="query1" class="mini-form" align="center" style="height:100%">
			        <table id="table1" class="table" style="height:100%">
			            <tr>
			                <td>
			                    單據號:
			                </td>
			                <td colspan="4">
			                    <input class="mini-textbox" name="orderNum" id="orderNum"/>
			                </td>
			                <td>
			                    開始日期:
			                </td>
			                <td colspan="4">
			                   <input  class="mini-datepicker" id="beginDate"  name="beginDate" format="yyyy-MM-dd"/>
			                </td>
			                <td>
			                    結束日期:
			                </td>
			                <td colspan="4">
			                   <input id="endDate" class="mini-datepicker"  />
			                </td>
                            <td>
			                       存儲性質:
			                </td>
			                <td colspan="4">
			                   <input id="typeName" class="mini-textbox"  />
			                </td>
			                <td>
			                        倉庫:
			                </td>
			                <td colspan="4">
			                   <input id="warehouseName" class="mini-textbox"  />
			                </td>
			          <td>
				            	 <a class="mini-button" onclick="listSearch()">
							        查詢
							    </a>
							    <a class="mini-button" onclick="reset()">
							        重置
				    		  </a>
			    			</td>
			    			
			            </tr>
			            	
			        </table>
			    </div>

JS查詢部分代碼

function listSearch(){
	var form = new mini.Form("#query1"); //獲取到總體查詢條件表單對象
	var data = form.getData(); //獲取表單中全部的值
	var t= data.beginDate; //獲取表單中日期的值
//如下將 控件中的日期轉化爲 yyyy-MM-dd 格式
	var time; 
	if(t!=""){
		var y = t.getFullYear();
		var m = t.getMonth()+1;
		m = m < 10 ? '0' + m : m;  
		var d = t.getDate();
		d = d < 10 ? ('0' + d) : d; 
	   time= y + '-' + m + '-' + d ;
	}
  alert(time);
	grid.load({orderNum:data.orderNum,beginDate:time});  
}

grid.load中的第一個 orderNum爲 Java中  InventoryInController list方法內須要從新聲明

接收從HTML中的傳入值

public ModelAndView list(HttpServletRequest request,
			HttpServletResponse response) {
		String p = request.getParameter("page");
		String limit = request.getParameter("limit");
		int toLimit = NumberUtils.toInt(limit, Constants.VALUE_PAGE_SIZE);
		int toStart = (NumberUtils.toInt(p, 0) - 1) * toLimit;

		String searchOrderNum = request.getParameter("orderNum");
		String searchbeginDate = request.getParameter("beginDate"); //添加

		Page page = inventoryInManager.getInventoryInDtoPage(toStart, toLimit,
				searchOrderNum,searchbeginDate); //添加searchbeginDate

inventoryInManager.getInventoryInDtoPage

查看 inventoryInManager.java中的  getInventoryInDtoPage方法

public Page getInventoryInDtoPage(int start, int pageSize, String orderNum, String beginDate) {
		StringBuffer sb = new StringBuffer();
		sb.append("select iii.ID,iii.CREATE_TIME,iii.CREATE_USER,iii.II_ARRIVE_DATE,iii.II_ORDER_DATE,iii.II_ORDER_NUM,iii.II_REMARK,");
		sb.append(" sp1.SP_NAME as 'STATUS_NAME',sp2.SP_NAME as 'TYPE_NAME',bw.BW_NAME as 'WAREHOUSE_NAME'");
		sb.append(" from inv_inventory_in iii,sys_param sp1,sys_param sp2,sys_param sp3,base_warehouse bw");
		sb.append(" where iii.II_STATUS_ID=sp1.ID");
		sb.append(" and iii.II_TYPE_ID=sp2.ID");
		sb.append(" and iii.II_WAREHOUSE_ID=bw.ID");
		sb.append(" and bw.BW_STATUS_ID=sp3.ID");
		// sb.append(" AND sp1.SP_FLAG='1'");
		// sb.append(" AND sp2.SP_FLAG='1'");
		// sb.append(" AND sp3.SP_FLAG='1'");
		// sb.append(" AND sp3.SP_CODE='1'");
		if (orderNum != null && !orderNum.equalsIgnoreCase("")) {
			sb.append(" AND iii.II_ORDER_NUM='" + orderNum + "'");
		}
		if (beginDate != null && !beginDate.equalsIgnoreCase("")) {
			sb.append(" AND iii.II_ORDER_DATE>='" + beginDate + "'");
		}
		
		sb.append(" ORDER BY iii.CREATE_TIME desc");

1.修改形參列表添加  String beginDate

2.添加查詢條件

if (beginDate != null && !beginDate.equalsIgnoreCase("")) {
            sb.append(" AND iii.II_ORDER_DATE>='" + beginDate + "'");
        }
