I am using angular 2 forms in my application and i have created the input based on my model. I have binded my input field with ngmodel and now I want to do a dirty check on this input field. So i have added input with # variable. Here is my code:-
<input type="text" [ngClass]="{red: sampledetails.rules[0].query3.dirty}" class="form-control" name="query3" id="query3" [(ngModel)]="sampledetails.rules[0].query3" #query3="ngModel">
But I am getting an error something like:-
There is no directive with "exportAs" set to "ngModel" ("="form-control" name="query3" id="query3" [(ngModel)]="sampledetails.rules[0].query3" [ERROR ->]#query3="ngModel">
Can anybody help me here..
You dont need to use #query3="ngModel" for angular.js 2,
so change
from
<input type="text" [ngClass]="{red: sampledetails.rules[0].query3.dirty}"
class="form-control" name="query3" id="query3"
[(ngModel)]="sampledetails.rules[0].query3" #query3="ngModel">
to (this will work)
<input type="text" [ngClass]="{red: sampledetails.rules[0].query3.dirty}"
class="form-control" name="query3" id="query3"
[(ngModel)]="sampledetails.rules[0].query3" >

In my custom directive, I need to update the validity of another input. The directive is something like this :
<customDirective="foo">, in which the value foo is the name of another ngModel.
In my direcitve, I can get its model by :
var foo = scope[attrs.foo];.
But how can I get its ngModelController, to set its validity? Just like this :
fooModelController.$setValidity('customDirective', true);
EDIT :
In html, the input is defined as :
<input type="text" name="dateDebut" id="dateDebut" class="form-control" ng-model="formData.dateDebut" customDirective="dateFin" required>
<input type="text" name="dateFin" id="dateFin" class="form-control" ng-model="formData.dateFin" customDirective="dateDebut" required>
I get the dom node by angular.element.find(document.querySelctor('#dateDebut'));
angular.element(document.querySelctor('#dateDebut')).controller('ngModel') -- this will give the ngModelController defined on #dateDebut element.

I would like to iterate over an array in AngularJS like this:
var languages = ['en', 'es', 'fr'];
To generate something like this:
<input type="text" ng-model="mymodel.en" placeholder="Name (EN)">
<input type="text" ng-model="mymodel.es" placeholder="Name (ES)">
<input type="text" ng-model="mymodel.fr" placeholder="Name (FR)">
I have tried this:
<div ng-repeat="language in languages">
<input type="text" ng-model="mymodel.{{language}}" placeholder="Name ({{language | uppercase}})">
</div>
But throws an error:
"Syntax Error: Token '{' is an unexpected token at column ..."
How should I perform this loop?
Use mymodel[language] instead of mymodel.{{language}}
<div ng-repeat="language in languages">
<input type="text" ng-model="mymodel[language]" placeholder="Name ({{language | uppercase}})">
</div>

See the plnkr, and start typing in any of the input fields to see the model changes.
you cantry something like this,
<input type="text" ng-model="mymodel[language]" ...
You shouldn't use {{}} notation inside ng-model here you can refer to your property in the mymodel object.
But it seems that you are trying to get binding via model somehow for your inputs. It's not gonna work in your case because you need to init mg-model directives.
For catching changed in your model from dynamically generated you need to compile used directives using $compile service.
Here you can check out sample. I googled it but I've solved similar problem in similar way.
I have a very simplified bit of html like so:
<call-panel>
<form name="hotListForm" >
<twilio>
<input type="text" name="phoneOtherText" id="phoneOtherText" class="form-control" required="required" ng-model="phoneNumber" ng-pattern="validation" ng-trim="false"/>
<span class="error" ng-show="hotListForm.phoneOtherText.$error.pattern">Not a valid phone number</span>
</twilio>
</form>
</call-panel>
But this doesn't work. Is there a special way to do this when in a nested directive. I have verified pattern is available.
Screenshot of it definitely being in the form and of form structure:
It is not working probably because you have the id set to "phoneOtherText" as well, try changing the id and try
I'm using AngularJS and have a form where I want the Submit button to be disabled if some fields are not filled in.
The standard way seems to be the following:
<form ng-app name="myForm">
<label>Name</label>
<input type="text" name="name" ng-model="form.name" required>
<input type="submit" ng-disabled="myForm.name.$invalid">
</form>
http://jsfiddle.net/YMSRU/
However, if I omit the model from the input field the validation doesn't work and I don't need any models on my input fields (I submit my form using the ngUpload directive so it's actually sent to the form action in an iframe).
Is there any solution or should I add random models just to make the validation work? It seems like a bad work-around.
You could simply do the invalid check at the form level, then no need to define a model for each input:
<form ng-app name="myForm">
<label>Name</label>
<input type="text" name="name" required>
<input type="submit" ng-disabled="myForm.$invalid">
</form>
You are missing your model at your test input tag : ng-model="form.name"
I have a PresentationsController which handles some POST action form. In this form I have data related to Presentation such as:
<input name="data[Presentation][title]" class="init-focus span4" type="text" id="PresentationTitle" required="required">
and those fields are handled correctly by controller. But PresentationModel hasMany Subject. So I want to include some presentation subjects in form. I did it like this:
<input name="data[Subject][0][subject]" disabled="disabled" class="subject" maxlength="255" type="text" id="Subject0Subject" required="required">
<input name="data[Subject][1][subject]" disabled="disabled" class="subject" maxlength="255" type="text" id="Subject0Subject" required="required">
But those data are not handled by Cake - I tried var_dump($this->request->data) in Controller but they are missing... for some reason Cake just ignores those data...
I am generating inputs dynamicalyy with jquery but it inputs are added correctly to form - I can see them in my browser html elements viewer:
<input name="data[Subject][0][subject]" maxlength="255" type="text" id="Subject0Subject" required="required">
<input name="data[Subject][1][subject]" disabled="disabled" class="subject" maxlength="255" type="text" id="Subject0Subject" required="required">
The above is what I view in html elements viewer - the first input is added "inline" from php and second is added dynamically with jquery. And only the first one is visible after POST.
When you set an input to disabled="disabled" it is NOT submitted. That goes for normal HTML and is not something CakePHP specific.
According to W3Schools.com:
Disabled elements in a form will not be submitted.
