我是MEAN STACK网络应用程序的新手 我想进行通用的独特验证,验证来自现场的模糊。
Register.html
static void channel_BasicNacks(object sender, RabbitMQ.Client.Events.BasicNackEventArgs e)
{
}
static void channel_BasicAcks(object sender, RabbitMQ.Client.Events.BasicAckEventArgs e)
{
}
directive.js
<input type="email" ng-model="user.email" name="email" placeholder="Enter your Email" ng-unique="User.email" required />
<span ng-show="myForm.email.$error.unique">Email already exists</span>
route.js
myapp.directive('ngUnique', ['$http', function($http) {
return {
require: 'ngModel',
link: function(scope, elem, attrs, ctrl) {
elem.on('blur', function(evt) {
scope.$apply(function() {
$http({
method: 'POST',
url: '/api/checkUnique',
data: {
dbFieldValue: elem.val(),
dbField: attrs.ngUnique
}
}).success(function(data, status, headers, config) {
ctrl.$setValidity('unique', data.status);
});
});
});
}
}
}]);
依赖关系
var User = require('./models/user');
app.post('/api/checkUnique', function(req, res) {
//console.log(req.body);
modelNameAndFieldName = req.body.dbField.split(".");
modelName = modelNameAndFieldName[0];
modelFieldName = modelNameAndFieldName[1];
modelFieldValue = req.body.dbFieldValue;
/*modelName.count({ modelFieldName: modelFieldValue }, function(err, data) {
if (err) {
res.json({ "status": false });
} else {
res.json({ "status": data > 0 ? true : false });
}
});*/
User.count({ email: modelFieldValue }, function(err, data) {
if (err) {
res.json({ "status": false });
} else {
res.json({ "status": data > 0 ? false : true });
}
});
});
上面的代码运行完美,但我希望这个功能很常见,这样在我的应用程序中我可以在任何模式和任何字段中使用它。
