一、架构方面
(一) Angular框架有service 、controller层:
在Angular里面,services作为单例对象在需要到的时候被创建,只有在应用生命周期结束的时候(关闭浏览器)才会被清除。而controllers在不需要的时候就会被销毁了(因为service的底层机制是通过闭包实现,如果过分使用会导致内存泄露从而导致性能问题)。
(二)Angular框架技术方面
1、angular.ui.grid 数据表的技术
基本结构的案例代码:
HTML页面:
//没有分页的情况 <div ui-grid="financialMainOption" ui-grid-selection ui-grid-pinning ui-grid-resize-columns style="height:399px;" class="grid"> </div> //分页的情况 <div ui-grid="gridOptionsJobCostTemplate" ui-grid-pagination ui-grid-selection ui-grid-resize-columns ui-grid-exporter class="grid" style="height: 550px;">
</div> /*分页的模块标志*/ ui-grid-pagination
JS页面:
$scope.rateIncomeOptions = { enablePagination : true,// 是否禁用分页 useExternalPagination : true,// 必须设为true才能赋值totalItems enableRowSelection : true, enableSelectAll : true, enableSorting: true, enableCellEditOnFocus:true,//单元格指令 enableRowSelection:false, columnDefs : [ {name : "rateNme",displayName : '费率名称' ,width : "140",enableCellEdit : false,cellClass:cellRateRow,cellTemplate:'<div class="rateOption_{{row.entity.rateUuid}}">{{row.entity.rateNme}}</div>'}, {name : "money",displayName : '实际金额' ,width : "80",type:'number',enableCellEdit : true,cellClass: cellClassOrderFun}, {name : 'unit',displayName : '单位' ,width : "60",type:'number',enableCellEdit : false,cellFilter:"rateUnitFilter"}, {name : "taxThan",displayName : '纳税比' ,width : "113",type:'number',enableCellEdit : true}, {name : 'remarks',displayName :'费用备注',width : "350",enableCellEdit : true}, {name : 'settlementStatus',displayName : '审核状态',width : "90",cellFilter : 'settlementStatus',enableCellEdit : false}, {name : 'isHaveTicket',displayName :'票',width : "50",enableCellEdit : false,cellFilter:"isOneOrZeroFilter"}, {name : 'serialNo',displayName :'序号',type:'number',width : "60",enableCellEdit : true ,sort: { direction: uiGridConstants.ASC, priority: 1 } }, ]}; // 将grid的API绑定到scope作用域 $scope.rateIncomeOptions.onRegisterApi = function(gridApi) { $scope.rateIncomeGridApi = gridApi; //点击行头触发 gridApi.selection.on.rowSelectionChangedBatch($scope, function (row, event) {/*row选择行头时,event触发该事件的源事件*/ $scope.selectRateIncomeDatas=gridApi.selection.getSelectedGridRows();//所有选中的行 $scope.sumInAmount = $scope.caluSumMoney($scope.selectRateIncomeDatas); //计算选中行的总金额 }); //点击行时触发 gridApi.selection.on.rowSelectionChanged($scope, function (row, event) {/*row选择的行,event触发该事件的源事件*/ $scope.selectRateIncomeDatas=gridApi.selection.getSelectedGridRows();//所有选中的行 $scope.sumInAmount = $scope.caluSumMoney( $scope.selectRateIncomeDatas); //计算选中行的总金额 }); //单元格进入事件 gridApi.edit.on.beginCellEdit($scope,function(row,column){ $scope.oldValue = row[column.name]; }); //编辑单元格离开的事件 gridApi.edit.on.afterCellEdit($scope,function(row,column){ //当值发生变化时修改 if($scope.oldValue!=row[column.name]){ } }); };
注意点:
(1)Excel导出,中文不乱码的设置,添加属性: 例如:
exporterCsvFilename:"运单报表"+new Date().getTime()+".csv", exporterOlderExcelCompatibility:true, //不使用UTF-8编码
(2)其中Grid中的列属性columnDefs 可以动态加载,例如:
statisticsReportService.buildWayBillReportColumns().success( function(columns) { hideLoading(); $scope.wayBillReportGrid.columnDefs = columns; //动态的赋值给列属性 //动态绑定行颜色 $.each(columns,function(i,column){ column.cellClass = cellClassJobFun; }); $scope.wayBillReportStatistical(); });
(3)清除已选中的行,操作方法,如下:
//设置选中的行为0 $scope.rateIncomeGridApi.selection.clearSelectedRows();
(4)
2、angular.ui.tree 树形tree技术
HTML页面代码:【控制菜单的收缩性】
<div ui-tree="treeOptions" id="tree-root"> <ol ui-tree-nodes="" ng-model="subjectTreeList"> <li ng-repeat="node in subjectTreeList" ui-tree-node ng-include="'nodes_renderer.html'" ng-show="visible(node)"></li> </ol> </div> <!--子模板部分--> <script type="text/ng-template" id="nodes_renderer.html"> <div ui-tree-handle class="tree-node tree-node-content"> <a class="btn btn-success btn-xs" ng-if="node.childSubjectSize && node.childSubjectSize > 0" data-nodrag ng-click="toggle(this)"> <span class="glyphicon" ng-class="{'glyphicon-chevron-right': collapsed, 'glyphicon-chevron-down': !collapsed}"> </span> </a> <span ng-if="node.subjectAlias">{{node.subjectCode}} : {{node.subjectAlias}}</span> <span ng-if="!node.subjectAlias">{{node.subjectCode}} : {{node.subjectName}}</span> <span> <a ng-show="node.subjectGrade>-1" class="pull-right btn btn-danger btn-xs" data-nodrag ng-click="removeSubItem(this)"><span class="glyphicon glyphicon-remove"></span></a> <a class="pull-right btn btn-primary btn-xs" data-nodrag ng-click="newSubItem(this)" style="margin-right: 8px;"><span class="glyphicon glyphicon-plus"></span></a> <a ng-show="node.subjectGrade>-1" class="pull-right btn btn-primary btn-xs" data-nodrag ng-click="editSubItem(this)" style="margin-right: 8px;"><span class="glyphicon glyphicon-edit"></span></a> </span> </div> <ol ui-tree-nodes="" ng-model="node.childFinanceSubjects" ng-class="{hidden: collapsed}" style="padding-left:29px;"> <li ng-show="node.collapsed" ng-repeat="node in node.childFinanceSubjects" ui-tree-node ng-include="'nodes_renderer.html'" ng-show="visible(node)"> </li> <li ng-show="!node.collapsed" ng-repeat="node in node.childFinanceSubjects" ui-tree-node data-collapsed="true" data-expand-on-hover="true" ng-include="'nodes_renderer.html'" ng-show="visible(node)"> </li> </ol> </script>
JS代码部分:
数据源:
$scope.getTreeList=function(){ loadingPage(); financeSubjectService.findAllFinanSubject2($scope.form).success(function(data){ $scope.allData=data.result; //查询树 $scope.subjectTreeList=[]; var subjectList=[]; if(data.result["-1"] && data.result["-1"].length>0){ $.each(data.result["-1"],function(j,obj){ //$scope.initSortNode(obj); subjectList.push(obj); }); } var nodeList=$scope.sortNode(subjectList); //创建根节点 var root={}; root.subjectName="财务科目"; root.subjectGrade=-1; root.subjectCode='000'; root.subjectType='PAYINCOME'; root.childSubjectSize=nodeList.length; root.childFinanceSubjects=nodeList; $scope.subjectTreeList.push(root); $scope.treeOptions.data=$scope.subjectTreeList; hideLoading(); }); };
tree结构的控制:
$scope.treeOptions = { //回调函数 beforeDrop : function (e) {//拖曳节点下降时候调用的函数 }, accept: function(sourceNodeScope, destNodesScope, destIndex) { return true; }, removed:function(node){ }, dropped:function(event){ }, dragStart:function(event){ }, dragMove:function(event){ }, dragStop:function(event){ }, beforeDrag:function(sourceNodeScope){ //拖曳之前检查节点 }, toggle:function(collapsed, sourceNodeScope){ if(!collapsed && sourceNodeScope.$modelValue.financeSubjectUuid){ loadingPage(); if($scope.allData){ sourceNodeScope.$modelValue.childFinanceSubjects=$scope.sortNode($scope.allData[sourceNodeScope.$modelValue.financeSubjectUuid]); hideLoading(); } } } };
注意点: 可以在toggle中控制节点的延迟加载。
