本文实现的是EasyUI-DataGrid行明细的增删改操作。具体参考来自以下文章:
官方DEMO---- DataGrid ---- Master Detail
icon.css
jquery.easyui.min.js
datagrid-detailview.js
jquery.js
注意以上文件版本,最好使用最新版。
2、JSP页面
页面中只需定义如下table即可:
<table id="listDetail"></table>
3、JS代码
初始化DataGrid,其中没特殊说明参数请参考上面提供的API。
- $(function(){
- $("#listDetail").datagrid({
- heigth:700,
- idField:‘id‘,
- url:‘<oz:contextPath/>/oa/receiptNoteDetailAction.do?action=page‘,
- queryParams:{‘viewType‘:‘RK‘,‘RKD_ID‘:_rkdId},
- singleSelect:false,
- fitColumns:true,
- nowrap:true,
- columns:[[
- {field:‘id‘,checkbox:true},
- {field:‘name‘,title:‘用品名称‘,width:100,editor:‘text‘,sortable:true},
- {field:‘produceType‘,title:‘用品型号‘,width:100,editor:‘text‘,sortable:true},
- {field:‘prickle‘,title:‘计量单位‘,width:100,editor:‘text‘,sortable:true},
- {field:‘count‘,title:‘入库数量‘,width:100,editor:‘text‘,sortable:true},
- {field:‘price‘,title:‘参考单价‘,width:100,editor:‘text‘,sortable:true},
- {field:‘subtotal‘,title:‘入库金额‘,width:100,editor:‘text‘,sortable:true}
- ]],
- toolbar:[{
- text:‘添加‘,
- <span style="white-space:pre"> <span style="white-space:pre"> </span></span>iconCls:‘icon-add‘,
- <span style="white-space:pre"> <span style="white-space:pre"> </span></span>handler:addItem
- },{
- text:‘删除‘,
- <span style="white-space:pre"> </span>iconCls:‘icon-remove‘,
- <span style="white-space:pre"> </span>handler:deleteItem
- },{
- text:‘刷新‘,
- <span style="white-space:pre"> </span>iconCls:‘icon-reload‘,
- <span style="white-space:pre"> </span>handler:refresh
- }],
- view: detailview,
- detailFormatter:function(index,row){
- return ‘<div id="detailForm-‘+index+‘" style="line-height:500px;"></div>‘;
- },
- onExpandRow: function(index,row){
- var id= $(this).datagrid(‘getRows‘)[index].id;
- $(‘#detailForm-‘+index).panel({
- doSize:true,
- border:false,
- cache:false,
- href:‘<oz:contextPath/>/oa/suppliesmgm/DE_ReceiptNoteDetail.jsp?rkdId=‘+_rkdId+‘&id=‘+id+‘&index=‘+index,
- onLoad:function(){
- $(‘#listDetail‘).datagrid(‘fixDetailRowHeight‘,index);
- $(‘#listDetail‘).datagrid(‘selectRow‘,index);
- }
- });
- $(‘#listDetail‘).datagrid(‘fixDetailRowHeight‘,index);
- },
- onDblClickRow:function(index,row){
- $(‘#listDetail‘).datagrid(‘expandRow‘, index);
- $(‘#listDetail‘).datagrid(‘fitColumns‘,index);
- $(‘#listDetail‘).datagrid(‘selectRow‘, index);
- }
- });
- });
特殊参数说明:
1、view: 定义DataGrid的view为detailview,需要引入datagrid-detailview.js
2、detailFormatter :定义了detailview的话,必须定义detailFormatter属性,用以初始化并返回一个DIV容器。
3、onExpandRow:展开后行触发事件,动态把Form放进DIV中。因为是动态加载Form,所以必须把DIV定义不同ID以识别不同的Form,如上面返回的DIV中
【 id="detailForm-‘+index+‘"】,否则在此例子中展开加载明细时会出现数据错位,注:是此例子。
增、删、改方法:(以下方法因为跟公司平台有关,所以仅供参考。另,这些方法都是写在初始化DataGrid页面而不是写在Form页面。)
- function addItem(){
- $(‘#listDetail‘).datagrid(‘appendRow‘,{isNewRecord:true});
- var index = $(‘#listDetail‘).datagrid(‘getRows‘).length - 1;
- $(‘#listDetail‘).datagrid(‘expandRow‘, index);
- $(‘#listDetail‘).datagrid(‘fitColumns‘,index);
- $(‘#listDetail‘).datagrid(‘selectRow‘, index);
-
- }
- function deleteItem(){
- var rows = $(‘#listDetail‘).datagrid(‘getSelections‘);
- if (null == rows || rows.length == 0) {
- OZ.Msg.info(‘请选择用品‘);
- return;
- }
- var ids=[];
- for(var i=0;i<rows.length;i++){
- ids.push(rows[i].id);
- }
- OZ.Msg.confirm(
- ‘删除入库用品明细将直接影响库存信息,确定删除吗?‘,
- function(){
- $.getJSON(
- contextPath + "/oa/receiptNoteDetailAction.do?action=deleteDetail&timeStamp=" + new Date().getTime(),
- {ids:ids.join(";")},
- function(json){
- if(json.result == true){
- OZ.Msg.info(‘删除成功‘);
- $(‘#listDetail‘).datagrid(‘reload‘);
- parent.refresh();
- }else{
- OZ.Msg.info(‘抱歉,删除失败‘);
- }
- }
- );
- }
- );
- }
- function saveItem(index){
- var suppliesCount=$(‘#detailForm-‘+index).find("#suppliesCount").val(),
- count=$(‘#detailForm-‘+index).find("#count").val();
-
- if(count == ‘‘ && count.length<1){
- OZ.Msg.info("出库数量不能为空");
- return false;
- }
-
- if(parseInt(count) > parseInt(suppliesCount)){
- OZ.Msg.info("出库数量不能大于实际库存数量");
- return false;
- }
-
- var strUrl = contextPath+‘/oa/issueNoteDetailAction.do?action=saveByAjax&timeStamp=‘ + (new Date().getTime());
- $.ajax({
- type: "POST",
- dataType: "json",
- url:strUrl ,
- data: $(‘#ozForm‘).serialize(),
- success: function(json, _status){
- $(‘#listDetail‘).datagrid(‘collapseRow‘,index);
- $(‘#listDetail‘).datagrid(‘reload‘);
- parent.refresh();
- },
- error: function(xhr, errorMsg, errorThrown){
- OZ.Msg.error("保存操作出现未处理异常!");
- }
- });
- }
- function cancelItem(index){
- var row = $(‘#listDetail‘).datagrid(‘getRows‘)[index];
- if (row.isNewRecord){
- $(‘#listDetail‘).datagrid(‘deleteRow‘,index);
- } else {
- $(‘#listDetail‘).datagrid(‘collapseRow‘,index);
- }
- }
4、Form表单(同样仅供参考,样式是公司平台的。官方例子的Form页面很简单,可参考它。)
- <html:form action="oa/issueNoteDetailAction.do" styleId="ozForm" styleClass="oz-form">
- <div class="oz-form-fields">
- <table cellpadding="0" cellspacing="0" class="dv-table" style="width:600px;background:#fafafa;padding:5px;margin-top:5px;">
- <tr>
- <td colspan="4">
- <div>
- <a href="#" class="easyui-linkbutton" iconCls="icon-save" plain="true" onclick="saveItem(<%= request.getParameter("index") %>)" id="btnSave">保存</a>
- <a href="#" class="easyui-linkbutton" iconCls="icon-cancel" plain="true" onclick="cancelItem(<%= request.getParameter("index") %>)">取消</a>
- </div>
- <hr/>
- </td>
- </tr>
- <tr>
- <td class="oz-form-label" style="width:80px">库存用品:</td>
- <td class="oz-property" colspan="3">
- <html:text property="supplies.name" styleId="suppliesName" styleClass="oz-form-zdField" readonly="true" style="width:150px"/>
- <button type="button" class="oz-form-button" onClick="onBtnSelectSupplies_Clicked(<%= request.getParameter("index") %>);">选择..</button>
- </td>
- </tr>
- <tr>
- <td class="oz-form-label" style="width:80px">用品型号:</td>
- <td class="oz-property">
- <html:text property="supplies.productType" styleId="suppliesProductType" styleClass="oz-form-zdField" readonly="true" style="width:150px"/>
- </td>
- <td class="oz-form-label" style="width:80px">参考单价:</td>
- <td class="oz-property">
- <html:text property="supplies.price" styleId="suppliesPrice" styleClass="oz-form-zdField" readonly="true" style="width:150px"/>
- </td>
- </tr>
- <tr>
- <td class="oz-form-label" style="width:80px">计量单位:</td>
- <td class="oz-property">
- <html:text property="supplies.prickle" styleId="suppliesPrickle" styleClass="oz-form-zdField" readonly="true" style="width:150px"/>
- </td>
- <td class="oz-form-label" style="width:100px">实际库存数量:</td>
- <td class="oz-property">
- <html:text property="supplies.realCount" styleId="suppliesRealCount" styleClass="oz-form-zdField" readonly="true" style="width:150px"/>
- </td>
- </tr>
- <tr>
- <td class="oz-form-label" style="width:80px">出库数量:</td>
- <td class="oz-property" colspan="3">
- <html:text property="count" styleId="count" styleClass="oz-form-btField" style="width:150px"/>
- </td>
- </tr>
- <tr>
- <td class="oz-form-label" style="width:80px">备注:</td>
- <td class="oz-property" colspan="3">
- <html:textarea property="beizhu" styleId="beizhu" styleClass="oz-form-field" style="width:500px" cols="15"/>
- </td>
- </tr>
- </table>
- </div>
- <html:hidden property="id" styleId="id"/>
- <html:hidden property="supplies.id" styleId="suppliesId"/>
- <html:hidden property="issueNote.id" styleId="issueNoteId"/>
- </html:form>
因为在初始化的时候有传id,rkdid,index参数过来,意义在于加载此Form的时候,可以利用Json根据id重新加载数据,这样可以避免保存外键时候出错。
- var id=<%= request.getParameter("id") %>;
- var _ckdId=<%= request.getParameter("ckdId") %>;
- var _index = <%= request.getParameter("index") %>;
-
- $(function(){
- $(‘#detailForm-‘+_index).find(‘#issueNoteId‘).val(_ckdId);
- loadomain();
- validate();
- });
-
- function loadomain(){
- if(typeof id == "undefined")
- id=-1;
- $.getJSON(
- contextPath + ‘/oa/issueNoteDetailAction.do?action=getIssueNoteDetail&id=‘ + id + ‘&timeStamp=‘ + new Date().getTime(),
- function(json){
- if(!json.isNew){
- $(‘#detailForm-‘+_index).find(‘#id‘).val(json.id);
- $(‘#detailForm-‘+_index).find(‘#beizhu‘).val(json.beizhu);
- $(‘#detailForm-‘+_index).find(‘#count‘).val(json.count);
-
- $(‘#detailForm-‘+_index).find(‘#suppliesId‘).val(json.suppliesId);
- $(‘#detailForm-‘+_index).find(‘#suppliesPrickle‘).val(json.suppilesPrickle);
- $(‘#detailForm-‘+_index).find(‘#suppliesProductType‘).val(json.suppliesProductType);
- $(‘#detailForm-‘+_index).find(‘#suppliesPrice‘).val(json.suppliesPrice);
- $(‘#detailForm-‘+_index).find(‘#suppliesName‘).val(json.suppliesName);
- $(‘#detailForm-‘+_index).find(‘#suppliesRealCount‘).val(json.suppliesRealCount);
-
- }else{
- $(‘#detailForm-‘+_index).find(‘#id‘).val(id);
- }
- })
- }
同时,重新加载数据时候注意按照不同DIV找到不同Form的各个字段,否则会加载数据错位。
$(‘#detailForm-‘+_index).find(‘#suppliesRealCount‘).val(json.suppliesRealCount);
4、后台代码就贴一段重新加载数据的方法出来,可参考参考:
- public ActionForward getIssueNoteDetail(ActionMapping mapping,ActionForm form,HttpServletRequest request,HttpServletResponse response) throws Exception{
- Long id=RequestUtils.getLongParameter(request, "id", -1);
- JSONObject json=new JSONObject();
- json.put("isNew",Boolean.valueOf(false));
- if(id != -1){
- IssueNoteDetail detail=this.getService().load(id);
- json.put("suppliesId",detail.getSupplies().getId());
- json.put("suppliesName",detail.getSupplies().getName());
- json.put("suppliesPrice",detail.getSupplies().getPrice());
- json.put("suppliesProductType",detail.getSupplies().getProductType());
- json.put("suppilesPrickle",detail.getSupplies().getPrickle());
- json.put("suppliesCount",detail.getSupplies().getCount());
- json.put("suppliesRealCount",detail.getSupplies().getRealCount());
-
- json.put("id",id);
- json.put("beizhu",detail.getBeizhu());
- json.put("count",detail.getCount());
- }else{
- json.put("isNew",Boolean.valueOf(true));
- }
- return renderJson(response, json.toString());
- }
