自设table表格，获取内容，并经弹出框的url传参,获取结果显示在弹出框,并加载合计

table表格，选择框

form id="editForm1">
    <table class="table_form">
        <td >经济性质：</td>
           <td >
                <input width="150" type="text" id="nature_id" readonly onclick="show_nature()">
                <input type="hidden" name="nature_name">
            </td>
        </tr>
        <tr><td colspan="3">请选择统计类型：</td></tr>
        <tr>
            <td align="right">
                <input type="radio" class="" name="rblViewStyle" value="1" checked="checked" class="mini-textboxlist">全口径
            </td>
            <td align="right">
                <input type="radio"class="" name="rblViewStyle" value="2" class="mini-textboxlist">区级分成
            </td>
        </tr>
        <tr>
            <td colspan="3" align="center">
                <a class="btn_color_1" id="BtnSaveBack1" onclick=" chaxun(0);"><i class="fa fa-save"></i> 查询</a>
            </td>
        </tr>
    </table>
</form>

弹出框，结果显示

<div id="editWindow1" class="mini-window" title="国地税分部门纳税统计" style="width:1400px; height :600px;" showModal="true" allowResize="true" allowDrag="true">
    <div id="grid" class="mini-datagrid" style="width: 100%; height: 100%; border:0;" dataField="rows" url="${ctx}/tAXPAYTAXEXTOTAL/gdHZ_dept" autoload="false" allowresize="false" sortField="ID"
         sortOrder="asc" pagesize="100" allowalternating="true" multiselect="true" onload="onLoad">
    </div>
</div>

点击查询，进入chaxun(0)方法

获取输入框中的内容
var nature_name=$('#nature_id').val();
    rblViewStyle=($("[name='rblViewStyle']:checked").val());
//将数据放在_SearchData中
var _SearchData = {};

_SearchData = $.extend(_SearchData, mini.decode("{'nature_name':'" + nature_name + "'}"));
_SearchData = $.extend(_SearchData, mini.decode("{'rblViewStyle':'" + rblViewStyle + "'}"));
//先加载弹出框
editWindow1.show();
加载弹出框中表格的内容
grid.set({
    columns: [
     { field: "TOWN", width: 140,align: "center", headerAlign: "center", allowSort: true, header: "所属镇办" },
        ]
});
//再执行弹出框grid中的url，并将数据传给后台，获取结果后将内容给弹出框
grid.load(_SearchData);

弹出框中有onload="onLoad"属性，加载onLoad()方法，添加合计新行

function onLoad(e) {
    var index = grid.getData().length;
    var row= {"TOWN": "合计", "ZCDJLX": "","MONEY_ALL": ""};
//添加新行
    grid.addRow(row, index);
//对index行,从第1列占位(合并)1行2列
    var marges = [
        { rowIndex: index, columnIndex: 1, rowSpan: 1, colSpan: 2},
    ];
    grid.mergeCells(marges);//进行合并

    var grids = e.sender;
    var MONEY_ALL=0;
    var length=grids.data.length;
//对每行内容进行相加
    for (var i = 0; i <length; i++) {
       MONEY_ALL =MONEY_ALL+( grids.data[i].MONEY_ALL =="" ? 0 : parseFloat(grids.data[i].MONEY_ALL));
    }
//修改该行
    grid.updateRow(row, { "MONEY_ALL": MONEY_ALL});
    
}
