在这个特殊的情况下,我有什么选项,使这些输入调用函数时,我按下Enter?
Html:
<form>
<input type="text" ng-model="name" <!-- Press ENTER and call myFunc --> />
<br />
<input type="text" ng-model="email" <!-- Press ENTER and call myFunc --> />
</form>
// Controller //
.controller('mycontroller', ['$scope',function($scope) {
$scope.name = '';
$scope.email = '';
// Function to be called when pressing ENTER
$scope.myFunc = function() {
alert('Submitted');
};
}])
FWIW -这是一个我用于基本确认/警报引导模式的指令,不需要<form>
(只需切换出jQuery的点击动作,无论你喜欢什么,并添加data-easy-dismiss到你的模式标签)
app.directive('easyDismiss', function() {
return {
restrict: 'A',
link: function ($scope, $element) {
var clickSubmit = function (e) {
if (e.which == 13) {
$element.find('[type="submit"]').click();
}
};
$element.on('show.bs.modal', function() {
$(document).on('keypress', clickSubmit);
});
$element.on('hide.bs.modal', function() {
$(document).off('keypress', clickSubmit);
});
}
};
});

});
}
};
});
如果你想调用函数没有形式,你可以使用我的ngEnter指令:
Javascript:
angular.module('yourModuleName').directive('ngEnter', function() {
return function(scope, element, attrs) {
element.bind("keydown keypress", function(event) {
if(event.which === 13) {
scope.$apply(function(){
scope.$eval(attrs.ngEnter, {'event': event});
});
event.preventDefault();
}
});
};
});
HTML:
<div ng-app="" ng-controller="MainCtrl">
<input type="text" ng-enter="doSomething()">
</div>
我在我的twitter和gist账户上提交了其他很棒的指令。
