如何在angular js中修改和更新数据表行？
提问于 2014-10-20 14:18:12
我正在学习angular js，我发现我有问题。
我正在创建一个新项目。
我有一些按钮编辑，添加，删除，
如果我点击我的编辑按钮，然后显示所有字段，但我只想显示当前字段，那么我就单击来更新此字段。
我的代码在这里
Anguar
var app = angular.module('addApp', []);
app.controller('modifyCtrl', ['$scope', function($scope){
$scope.tabelsData= [
{'name':'rohit', 'dob':'15-august-1985', 'emailId':'rohit@rohit.com', 'phone':'9999999999', 'address':'Delhi Rohini', 'id':'0' },
{'name':'aman', 'dob':'26-july-1975', 'emailId':'haryanat@hr.com', 'phone':'9874563210', 'address':'Haryana Sonepat', 'id':'1' },
{'name':'devraj', 'dob':'27-march-1980', 'emailId':'punjab@punjab.com', 'phone':'7410258963', 'address':'Punjab AmritSar', 'id':'2' }
];
$scope.modify = function(tableData){
$scope.modifyField = true;
$scope.viewField = true;
};
$scope.update = function(tableData){
$scope.modifyField = false;
$scope.viewField = false;
};
}]);HTML代码为
<div ng-app="addApp">

如果您只希望一行在单击相应的修改按钮时显示输入，则有两种选择：
1)将布尔值附加到tabelsData数组的每个JSON索引。
2)制作一个包含这些布尔值的镜像数组。
在这种情况下，有两个单独的布尔值是没有用的，因为每个布尔值都是在切换的基础上处理的：
下面是执行第二种方法的核心代码，因为我假设您希望数据保持不变：
JS：
$scope.editingData = {};
for (var i = 0, length = $scope.tabelsData.length; i < length; i++) {
$scope.editingData[$scope.tabelsData[i].id] = false;
}
$scope.modify = function(tableData){
$scope.editingData[tableData.id] = true;
};
$scope.update = function(tableData){
$scope.editingData[tableData.id] = false;
};Html：
<tbody>
<tr ng-repeat="tableData in tabelsData">
<td>
<div ng-hide="editingData[tableData.id]">{{tableData.name | uppercase}}</div>
<div ng-show="editingData[tableData.id]"><input type="text" ng-model="tableData.name" /></div>
</td>
<td>
<div ng-hide="editingData[tableData.id]">{{tableData.dob}}</div>
<div ng-show="editingData[tableData.id]"><input type="text" ng-model="tableData.dob" /></div>
</td>
<td>
<div ng-hide="editingData[tableData.id]">{{tableData.emailId}}</div>
<div ng-show="editingData[tableData.id]"><input type="text" ng-model="tableData.emailId" /></div>
</td>
<td>
<div ng-hide="editingData[tableData.id]">{{tableData.phone}}</div>
<div ng-show="editingData[tableData.id]"><input type="text" ng-model="tableData.phone" /></div>
</td>
<td>
<div ng-hide="editingData[tableData.id]">{{tableData.address}}</div>
<div ng-show="editingData[tableData.id]">
<textarea ng-model="tableData.address"></textarea>
</div>
</td>
<td>
<button ng-hide="editingData[tableData.id]" ng-click="modify(tableData)">Modify</button>
<button ng-show="editingData[tableData.id]" ng-click="update(tableData)">Update</button>
<button ng-hide="viewField">Add</button>
<button ng-hide="viewField">Remove</button>
</td>
</tr>

以下是Angular2中的一个示例(这不适用于AngularJS!)

<tr *ngFor="let object of data | orderBy : convertSorting(); let rowIndex = index">
<td *ngFor="let column of columns" class="{{column.variable}}-td">
<div *ngIf="!toUpdates[object['id']]" >{{object[column.variable] | format: column.filter}}</div>
