Question

我正在尝试将复选框更改为切换样式。该复选框使用ng-repeat呈现。问题是，当我单击任何开关样式的复选框时，只有顶部的一个会发生变化。

怎么了？

var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope) {
  $scope.records = [
    "John Doe",
    "Tom Jones",
    "James Riley",
    "Ted Mandy",
  ]
});

input[type=checkbox] {
  height: 0;
  width: 0;
  visibility: hidden;
}

label {
  cursor: pointer;
  text-indent: -9999px;
  width: 60px;
  height: 23px;
  background: grey;
  display: block;
  border-radius: 100px;
  position: relative;
}

label:after {
  content: '';
  position: absolute;
  top: 5px;
  left: 5px;
  width: 18px;
  height: 12px;
  background: #fff;
  border-radius: 90px;
  transition: 0.3s;
}

input:checked+label {
  background: #bada55;
}

input:checked+label:after {
  left: calc(100% - 5px);
  transform: translateX(-100%);
}

label:active:after {
  width: 130px;
}

Answer 1

您正在创建多个具有相同ID的复选框。试试这个：

<tr ng-repeat="(i,x) in records">
    <td>{{x}}</td>
    <td>
        <input type="checkbox" id="switch{{i}}" />
        <label for="switch{{i}}"></label>
    </td>
</tr>

Answer 2

您尚未将重复的复选框输入绑定到任何模型。

此外，您正在重新使用相同的id值。

考虑扩展您的records模型，使其也包含复选框的活动状态。

<tr ng-repeat="record in records">
    <td>{{ record.name }}</td>
    <td>
        <input type="checkbox" id="switch{{ $index }} ng-model="record.active"  />
        <label for="switch{{ $index }}"></label>
    </td>
</tr>

...

$scope.records = [
    { name: "John Doe", active: false },
    { name: "Tom Jones", active: false },
    { name: "James Riley", active: false },
    { name: "Ted Mandy", active: false },
];
