需求
1 还有个总的checkbox 负责全选和反选
2 当每一项开头都选中checkbox的时候，上面的全选自动选上
3 当全选后，取消其中一项的checkbox,全选取消
<div ng-controller="myController"> <label for="flag">全选 <input id="flag" type="checkbox" ng-model="select_all" ng-change="selectAll()"> </label> <ul> <li ng-repeat="i in list"> <input type="checkbox" ng-model="i.checked" ng-change="selectOne()"> <span>{{id}}</span> </li> </ul> </div>
var app = angular.module('myApp',[]);
app.controller('myController', ['$scope', function ($scope) {
$scope.list = [
{'id': 101},
{'id': 102},
{'id': 103},
{'id': 104},
{'id': 105},
{'id': 106},
{'id': 107}
];
$scope.m = [];
$scope.checked = [];
$scope.selectAll = function () {
if($scope.select_all) {
$scope.checked = [];
angular.forEach($scope.list, function (i) {
i.checked = true;
$scope.checked.push(i.id);
})
}else {
angular.forEach($scope.list, function (i) {
i.checked = false;
$scope.checked = [];
})
}
console.log($scope.checked);
};
$scope.selectOne = function () {
angular.forEach($scope.list , function (i) {
var index = $scope.checked.indexOf(i.id);
if(i.checked && index === -1) {
$scope.checked.push(i.id);
} else if (!i.checked && index !== -1){
$scope.checked.splice(index, 1);
};
})
if ($scope.list.length === $scope.checked.length) {
$scope.select_all = true;
} else {
$scope.select_all = false;
}
console.log($scope.checked);
}
}]);
