我正在尝试使用指令使用iCheck复选框。我的指令设置如下。
.module('app').directive('bootstrapCheck', ['$timeout', '$parse', function ($timeout, $parse) {
return {
compile: function (element, $attrs) {
var icheckOptions = {
checkboxClass: 'icheckbox_minimal',
radioClass: 'iradio_minimal'
};
var modelAccessor = $parse($attrs['ngModel']);
return function ($scope, element, $attrs, controller) {
var modelChanged = function (event) {
$scope.$apply(function () {
modelAccessor.assign($scope, event.target.checked);
});
};
$scope.$watch(modelAccessor, function (val) {
var action = val ? 'check' : 'uncheck';
element.iCheck(icheckOptions, action).on('ifChanged', modelChanged);
});
};
}
};
}]);
我的复选框是ng-repeat。我想发送当前对象的功能,以进一步处理它。我的html设置如下。
<input type="checkbox" ng-model="item.isSelected" ng-change="onChangeEvent(item)" bootstrap-check>
每次更改任何复选框时都会触发modelChanged。但我试图访问modelChanged函数内的项目来进一步处理它。请指导。

您可以将item
传递给指令范围,并在link
函数内访问它。与item
一起,您还可以将onChangeEvent处理程序传递给指令。试试这个。
JS
angular.module('app').directive('bootstrapCheck', ['$timeout', '$parse', function ($timeout, $parse) {
return {
scope: {
item: '=',
onChangeEvent: '&'
},
compile: function (element, $attrs) {
var icheckOptions = {
checkboxClass: 'icheckbox_minimal',
radioClass: 'iradio_minimal'
};
var modelAccessor = $parse($attrs['ngModel']);
return function ($scope, element, $attrs, controller) {
var modelChanged = function (event) {
//Here $scope.item will give you the item
//This will trigger the parent controller's onChangeEvent set in the directive markup
$scope.onChangeEvent({ item: $scope.item });
$scope.$apply(function () {
modelAccessor.assign($scope, event.target.checked);
});
};
$scope.$watch(modelAccessor, function (val) {
var action = val ? 'check' : 'uncheck';
element.iCheck(icheckOptions, action).on('ifChanged', modelChanged);
});
};
}
};
}]);
HTML
<input type="checkbox"
ng-model="item.isSelected"
item="item"
on-change-event="onChangeEvent(item)" bootstrap-check>
