请参见朋克车
在jQuery中，我可以获取其 td 的文本并将其置于警报中，但是如何在Angular中进行显示呢?我应该将其设为javascript原生语言吗?
In jQuery I can get the text of its td and put it in an alert but how can I make it in Angular? Should I make it an javascript native?
这是脚本
var app = angular.module('plunker',[]);
app.controller('ctrl',function($scope){
$scope.edit = function(){
alert("ID = " + $scope.id + "\n NAME = " + $scope.name);
};
$scope.items = [
{id:"1",name:"name 1"},
{id:"2",name:"name 2"},
{id:"3",name:"name 3"}
];
});
HTML
<body ng-controller="ctrl" ng-app="plunker">
<table>
<thead>
<tr>
<th>id</th>
<th>name</th>
<th>edit</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="x in items">
<td ng-model="x.id">{{x.id}}</td>
<td>{{x.name}}</td>
<td><button ng-click="edit()">edit</button></td>
</tr>
</tbody>
</table>
</body>
PS
ng-repeat是动态的，那么我如何获得它的价值?
The ng-repeat is dynamic so how can I get the value of it?
推荐答案
只需将值作为参数传递给edit函数，
Just pass the value to the edit function as parameter,
<td><button ng-click="edit(x)">edit</button></td>
然后是功能
$scope.edit = function(x){
console.log("Id is",x.id);
}
演示
var app = angular.module('plunker',[]);
app.controller('ctrl',function($scope){
$scope.edit = function(){
alert("ID = " + $scope.id + "\n NAME = " + $scope.name);
};
$scope.items = [
{id:"1",name:"name 1"},
{id:"2",name:"name 2"},
{id:"3",name:"name 3"}
];
$scope.edit = function(x){
console.log("$$Id is",x.id);
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-controller="ctrl" ng-app="plunker">
<table>
<thead>
<tr>
<th>id</th>
<th>name</th>
<th>edit</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="x in items">
<td ng-model="x.id">{{x.id}}</td>
<td>{{x.name}}</td>
<td><button ng-click="edit(x)">edit</button></td>
</tr>
</tbody>
</table>
