动态修改datagrid中的numberbox的最大值和最小值

注意datagrid使用的触发函数是:

onBeginEdit,只有在这个触发条件下，editor才真正初始化完成，不然没法动态修改numberbox中的最大最小值。

示例代码:(注意这一块:onBeginEdit:changeNumberMax)

<table id="dg"  style="width:960px;height:auto"
                                    data-options="
                                        singleSelect: true,
                                        url: '<%=request.getContextPath() %>/settlementRule/relatedServices?prodId=${productDto.prodId }',
                                        method:'get',
                                        onLoadSuccess:checkData,
                                        onBeginEdit:changeNumberMax
                                    ">
                                <thead>
                                    <tr>
                                        <th data-options="field:'id',width:150,hidden:true">规则ID</th>
                                        <th data-options="field:'createTime',width:150,hidden:true">规则创建时间</th>
                                        <th data-options="field:'prodSrvId',width:150,hidden:true">服务ID</th>
                                        <th data-options="field:'srvName',width:150">服务名称</th>
                                        <th data-options="field:'srvCode',width:150">服务编号</th>
                                        <th data-options="field:'providerName',width:150">所属厂商</th>
                                        <th data-options="field:'srvTypeDesc',width:108">服务类型</th>
                                        <th data-options="field:'rate',width:100,formatter:function(value,row){if(value!=null&&value!=0) {return value+'%';}}">分摊比例</th>
                                        <th data-options="field:'ruleType',width:150,formatter:function(value,row){if(value==${FIXED_ACCOUNT_SETTLEMENT}) {return '固定金额结算'} else if(value==${PROPORTION_SETTLEMENT}) { return '按比例结算'} },
                                        editor:{type:'combobox',options:{url: '<%=request.getContextPath() %>/settlementRule/getSettlementRuleTypeEnums',valueField:'enumEntryValue',textField:'enumEntryLabel',
                                        method:'get',editable:'true',panelHeight: 'auto',required:'true',editable:false}}">结算类型</th>
                                        <th data-options="field:'val',width:150,formatter:function(value,row){if(value!=null){if(row.ruleType==${PROPORTION_SETTLEMENT}) {return value+'%';} else if(row.ruleType==${FIXED_ACCOUNT_SETTLEMENT}) {return value;}}},editor:{type:'numberbox',options:{required:'true',min:0,precision:2}}">结算规则</th>
                                    </tr>
                                </thead>
                            </table>

相应的触发函数:

function  changeNumberMax(rowIndex,rowData)  {
			var ruleType=rowData.ruleType;
			if(ruleType==0) {
				var sharePercent=rowData.rate;
				var ed = $('#dg').datagrid('getEditor', {index:rowIndex,field:'val'});
				$(ed.target).numberbox({
				    max: ${productDto.prodPrice }*sharePercent/100,
				    precision: 2,
				    min:0
				});
		    }
		}
