我在我的网络应用程序中使用ui-grid.
一切都运行正常,问题是当我刷新网格数据时,选择被删除. 在小提琴中,当我选择一行然后点击刷新按钮时,ui-grid选择被删除. JSFiddle：http://jsfiddle.net/mdawood1991/xyuotpe8/6/ HTML： <div ng-controller="MyCtrl as controller">
<button ng-click="controller.refreshData()" type="button">
Refresh
</button>
<div ui-grid="controller.assetListGrid" ui-grid-selection></div>
</div>
控制器： var myApp = angular.module('myApp',["ui.grid","ui.grid.selection"]);
//myApp.directive('myDirective',function() {});
//myApp.factory('myService',function() {});
myApp.controller("MyCtrl",function($scope) {
var self = this;
$scope.name = 'Superhero';
self.assetListGrid = {};
self.gridOptions = {
enableFiltering: true,enableGridMenu: true,ang
enableColumnMenus: false,enableRowSelection: true,enableSelectAll: false,multiSelect: false,enableHorizontalScrollbar: 1,columnDefs: [{
name: 'assetId'
},{
name: 'reference',enableHiding: false,width: 250,resizeable: true
}],onRegisterApi: function(gridApi) {
self.assetGridObject = gridApi;
// register the onRowSelect Function here
//this.assetGridObject.selection.on.rowSelectionChanged(null,function(row) {
// if (row.isSelected)
// });
},appScopeProvider: self
}
self.initGrid = function() {
self.assetListGrid = self.gridOptions;
self.assetListGrid.data = "controller.gridAssets"
}
self.loadInitData = function() {
self.gridAssets = [{
assetId: 1,reference: "Dawood"
},{
assetId: 2,reference: "Dawood 2"
},{
assetId: 3,reference: "Dawood 3"
},{
assetId: 4,reference: "Dawood 4"
},]
}
self.refreshData = function() {
console.log("Data refresh")
self.gridAssets = [{
assetId: 1,reference: "Refresh"
},reference: "Refresh 2"
},reference: "Refresh 3"
},reference: "Refresh 4"
},]
}
self.initGrid();
self.loadInitData();
});
我如何保持选择？ 解决方法
好像我找到了一个解决方案：
我做的是在选择行时,首先将选定的行放在临时对象中 onRegisterApi: function(gridApi) {
self.assetGridObject = gridApi;
// register the onRowSelect Function here
self.assetGridObject.selection.on.rowSelectionChanged(null,function(row) {
if (row.isSelected) {
self.assetGridObject.grid.appScope.selectedRow = row.entity;
}
});
},
FIDDLE：http://jsfiddle.net/mdawood1991/02dpggyo/2/ 然后,当刷新数据时,我正在检查是否选择了一行,如果选择了一行,我将从新数据数组中获取该行的最新值,这就是刷新数据方法现在的样子： self.refreshData = function() {
console.log("Data refresh")
self.gridAssets =
[
{assetId: 1,reference: "Refresh 1"},{assetId: 2,reference: "Refresh 2"},{assetId: 3,reference: "Refresh 3"},{assetId: 4,reference: "Refresh 4"}];
if (self.selectedRow)
{
console.log("Row is selected");
//THIS LINE HERE I THINK IS THE KEY -
self.assetGridObject.grid.modifyRows(self.gridAssets);
// GET THE ROW FROM NEWLY LOADED DATA
var selectedRoww = null;
for (var i = 0; i < self.gridAssets.length; i++)
{
//COMPARING BASED ON MY asseId AS THIS IS THE VALUE THAT WILL NOT CHANGE IN MY GRID - OTHER COLUMS CAN CHANGE
if (self.gridAssets[i].assetId == self.selectedRow.assetId)
{
selectedRoww = self.gridAssets[i];
}
}
// THIS LINE HERE IS SELECTING THE ROW FROM THE GRID
self.assetGridObject.selection.selectRow(selectedRoww);
}
}
