问题
I'm trying to integrate JQuery.iCheck (plugin for checkbox&Radio buttons styling).
I followed few suggestions here that said that the way to integrate a jQuery plugins to be fully compatible with Angular ngRepeat is by using directives.
So I implemented a directive:
webApp.directive('icheck', function($timeout, $parse) {
return {
link: function($scope, element, $attrs) {
return $timeout(function() {
var ngModelGetter, value;
ngModelGetter = $parse($attrs['ngModel']);
value = $parse($attrs['ngValue'])($scope);
return $(element).iCheck({
checkboxClass: 'icheckbox_minimal',
radioClass: 'iradio_minimal-grey',
checkboxClass: 'icheckbox_minimal-grey',
increaseArea: '20%'
}).on('ifChanged', function(event) {
if ($(element).attr('type') === 'checkbox' && $attrs['ngModel']) {
$scope.$apply(function() {
return ngModelGetter.assign($scope, event.target.checked);
});
}
if ($(element).attr('type') === 'radio' && $attrs['ngModel']) {
return $scope.$apply(function() {
return ngModelGetter.assign($scope, value);
});
}
});
});
}
};
});
This directive does not fully work with my ngRepeat elements and does not change
the properties of the object vote.
My code - Git
My code:
var webApp = angular.module('webApp', []);
//controllers
webApp.controller ('VotesCtrl', function ($scope, Votes) {
$scope.votes = Votes;
$scope.statuses = ["Approved","Pending","Trash","Spam"];
$scope.selectedID = 1;
$scope.expand = function(vote) {
console.log("show");
$scope.vote = vote;
$scope.selectedID = vote.id;
};
$scope.change = function() {
for(var i = 0; i < $scope.votes.length; i++) {
if($scope.votes[i].cb) {
$scope.votes[i].status = $scope.votes.status;
$scope.votes[i].cb = false;
}
$scope.show = false;
}
};
});
//services
webApp.factory('Votes', [function() {
//temporary repository till integration with DB this will be translated into restful get query
var votes = [
{
id: '1',
created: 1381583344653,
updated: '222212',
ratingID: '3',
rate: 5,
ip: '198.168.0.0',

ratingID: '3',
rate: 1,
ip: '198.168.0.3',
status: 'Spam',
userIdentification:'IP-ADDRESS'
}
];
return votes;
}]);
webApp.directive('icheck', function($timeout, $parse) {
return {
link: function($scope, element, $attrs) {
return $timeout(function() {
var ngModelGetter, value;
ngModelGetter = $parse($attrs['ngModel']);
value = $parse($attrs['ngValue'])($scope);
return $(element).iCheck({
checkboxClass: 'icheckbox_minimal',
radioClass: 'iradio_minimal-grey',
checkboxClass: 'icheckbox_minimal-grey',
increaseArea: '20%'
}).on('ifChanged', function(event) {
if ($(element).attr('type') === 'checkbox' && $attrs['ngModel']) {
$scope.$apply(function() {
return ngModelGetter.assign($scope, event.target.checked);
});
}
if ($(element).attr('type') === 'radio' && $attrs['ngModel']) {
return $scope.$apply(function() {
return ngModelGetter.assign($scope, value);
});
}
});
});
}
};
});

Already solved on this link: https://github.com/fronteed/iCheck/issues/62 by wajatimur
webApp.directive('icheck', function($timeout, $parse) {
return {
require: 'ngModel',
link: function($scope, element, $attrs, ngModel) {
return $timeout(function() {
var value;
value = $attrs['value'];
$scope.$watch($attrs['ngModel'], function(newValue){
$(element).iCheck('update');
})
return $(element).iCheck({
checkboxClass: 'icheckbox_flat-aero',
radioClass: 'iradio_flat-aero'
}).on('ifChanged', function(event) {
if ($(element).attr('type') === 'checkbox' && $attrs['ngModel']) {
$scope.$apply(function() {
return ngModel.$setViewValue(event.target.checked);
});
}
if ($(element).attr('type') === 'radio' && $attrs['ngModel']) {
return $scope.$apply(function() {
return ngModel.$setViewValue(value);
});
}
});
});
}
};
});
回答2:
With the code from XaReSx answer I had one issue : When updating the model from the scope the radio doesn't changed. I had to add a timeout in the model watch :
$scope.$watch($attrs['ngModel'], function (newValue) {
$timeout(function () {
$(element).iCheck('update');
})
})

Here is a better sololution by hackthis02
.directive('icheck', function ($timeout, $parse) {
return {
require: 'ngModel',
link: function ($scope, element, $attrs, ngModel) {
return $timeout(function () {
var value;
value = $attrs['value'];
$scope.$watch($attrs['ngModel'], function (newValue) {
$(element).iCheck('update');
});
$scope.$watch($attrs['ngDisabled'], function (newValue) {
$(element).iCheck(newValue ? 'disable' : 'enable');
$(element).iCheck('update');
})
return $(element).iCheck({
checkboxClass: 'icheckbox_square-blue',
radioClass: 'iradio_square-blue'
}).on('ifChanged', function (event) {
if ($(element).attr('type') === 'checkbox' && $attrs['ngModel']) {
$scope.$apply(function () {
return ngModel.$setViewValue(event.target.checked);
})
}
}).on('ifClicked', function (event) {
if ($(element).attr('type') === 'radio' && $attrs['ngModel']) {
return $scope.$apply(function () {
//set up for radio buttons to be de-selectable
if (ngModel.$viewValue != value)
return ngModel.$setViewValue(value);
else
ngModel.$setViewValue(null);
ngModel.$render();
return
});
}
});
});
}
};
});
