我有以下jQuery点击事件,我正在尝试" angularize"使用 ng-click ,但无法弄清楚如何。
$('body').on('click change', 'input[type="radio"]:not([disabled])', function(event) {
$(this).prop('checked') //if checked
? $(this).prop('checked',false).data('waschecked', false) //uncheck
: $(this).prop('checked',true).data('waschecked', true); //else check
});
目标是检查项目是否确实已经被选中,如果已经选中,则重置单选按钮。
有人能指出我正确的方向吗?

这是非标准行为,但这是一个例子,可以帮助您查找:https://jsbin.com/sicuhugevu/1/edit?html,js,output
对于那些不想访问JSBin的人:
JS:
angular
.module('test', [])
.controller('testCtrl', function($scope) {
$scope.radios = {
selected: null,
last: null
};
$scope.radioClick = function(event) {
if ($scope.radios.last === $scope.radios.selected) {
$scope.radios.selected = null;
$scope.radios.last = null;
return;
}
$scope.radios.last = event.target.value;
};
});

<label><input type="radio" name="test" value="3"
data-ng-click="radioClick($event)"
data-ng-model="radios.selected">Option 3</label>
</div>
</body>

本地版本:
angular
.module('test', [])
.controller('testCtrl', function($scope) {
$scope.radios = {
selected: null,
last: null
};
$scope.radioClick = function(event) {
if ($scope.radios.last === $scope.radios.selected) {
$scope.radios.selected = null;
$scope.radios.last = null;
return;
}
$scope.radios.last = event.target.value;
};
});

我的建议是为组状态使用一个值,为按钮使用不同的值,并使用ng-click
将按钮与组状态进行比较。
例如:
<input type="radio" ng-checked="true" ng-model="buttons" value="one" ng-click="radioChanged()">
<input type="radio" ng-checked="false" ng-model="buttons" value="two" ng-click="radioChanged()">
<input type="radio" ng-checked="false" ng-model="buttons" value="three" ng-click="radioChanged()">
$scope.radioChanged = function (){
if ($scope.buttons === $scope.group){
$scope.buttons = undefined;
}
$scope.group = $scope.buttons;
console.log($scope.group, $scope.buttons);
};
