I have inputs in a web page without the form tag (useless to me).
How can I get their validity status inside the HTML ? This
<input name="myInput" type="text" ng-pattern="/^[0-9]{13}$/">
<input type="button" ng-show="myInput.$valid">
doesn't work.
I'm afraid that won't work without wrapping it in a form as you need to access those fields via the form's controller.
<form name="myForm">
<input name="myInput" type="text" ng-pattern="/^[0-9]{13}$/">
<input type="button" ng-show="myForm.myInput.$valid">
</form>
Should work.
If you're unable to use the form tag for any reason, you'll have to wire that up manually.

Please think in angularjs way.
Actually my layout is different.
I have input fields inside form and also have input fields outside form, this is a special case in my product.
I know about form attribute in HTML5
But
In AngualrJS:
I want to achieve outside form input fields works as good as inside form input field works for validation purpose.
Is it possible? We can not remove the place of form tag.
If Yes please guide me.
<div ng-app="myApp" ng-controller="validateCtrl" >
<h6>Validation Example</h6>
<form id="frm" name="myForm" novalidate>
Inside form
<p>
<input type="submit" ng-disabled="myForm.email.$dirty && myForm.email.$invalid">
</p>
</form>
Outside form
<p>Email:<br>
<input form="frm" type="email" name="email" ng-model="email" required>
</p>
</div>
Plunker
Suppose I have the following setup:
<form>
<input type="text" id="text1">
<input type="text" id="text2">
</form>
In AngularJS, is there any way for me to determine when, say, the user deselects #text1, for example by clicking #text2, or clicking somewhere else on the screen? I am aware the ng-change lets me listen to changes in the value of #text1 itself, but I see no way to determine when the user actually leaves the field.
You can use ngBlur for this
https://docs.angularjs.org/api/ng/directive/ngBlur
<form>
<input type="text" id="text1" ng-blur="iHaveLostFocusDoSomethingWithIt()">
<input type="text" id="text2">
</form>
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
The validation is being highlighted correctly, but when I click submit button, even with empty form field, the form is still being submitted (and nick value is undefined)
I tried adding novalidate to the form -- but that didn't help.
<form class="nick" ng-submit="joinChat()">
<input type="text" required name="nick" ng-model="nick" ng-minlength="2" ng-maxlength="10">
<button>Join</button>
</form>
I'm trying to follow this guide here:
http://www.ng-newsletter.com/posts/validations.html
The joinChat() function doesn't do any validation itself. As its my understanding this shouldn't be necessary when using Angular form validation.
$scope.joinChat = function(){
socket.emit('chat:join', { nick: $scope.nick });
};
Invalid input does not prevent angular form submission, instead try this:
<form class="nick" novalidate ng-submit="joinChat()" name="myform">
<input type="text" ng-required="true" name="nick" ng-model="nick" ng-minlength="2" ng-maxlength="10">
<button ng-disabled="myform.$invalid">Join</button>
</form>
Fiddle
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"
