I m trying to add angularJs event to a button if value of input field changes. But i cannot find a solution how can i do it. I know how to detect change but do not know how to add a new event using controller.
Let me illustrate by example:
<form name="addNewCourse">
<input ng-model="courseNameEdit" ng-value="courseName" ng-pattern="regex" ng-trim="false" name="addNewCourseField" ng-minlength="5" ng-maxlength="60" required>
<div ng-messages="addNewCourse.addNewCourseField.$error" style="text-align: left !important; color:red;">
<div ng-message="required">This field is required*</div>
<div ng-message="pattern">Must be only digits or numbers</div>
<div ng-message="maxlength">Must not exceed 60 characters</div>
<div ng-message="minlength">Must not be smaller than 5 characters</div>
</div>
<button class="btn btn-primary" ng-click="saveCourseNameFunc(courseNameEdit)">Save</button>
</form>
what i want is to add ng-disabled="addNewCourse.$invalid" into the button if value change using controller. Thanks in Advance.
If I'm not wrong here, You are about to validate your form while field value changes via the controller. Try below solution and let me know if this will not work for you.
FORMOBJECT.$setSubmitted();
You can also try triggering change event of that field via controller like:
angular.element('#INPUT_ID').trigger('change');
Hope you will get the solution from one of the given above.
How about using ng-change and a boolean in your ng-disabled expression activate the disability simply.
<form name="addNewCourse">
<input ng-change="changed()" ng-disabled="addNewCourse.$invalid && activeDisable" ng-model="courseNameEdit" ng-value="courseName" ng-pattern="regex" ng-trim="false" name="addNewCourseField" ng-minlength="5" ng-maxlength="60" required>
<div ng-messages="addNewCourse.addNewCourseField.$error" style="text-align: left !important; color:red;">
<div ng-message="required">This field is required*</div>
<div ng-message="pattern">Must be only digits or numbers</div>
<div ng-message="maxlength">Must not exceed 60 characters</div>
<div ng-message="minlength">Must not be smaller than 5 characters</div>
</div>
<button class="btn btn-primary" ng-click="saveCourseNameFunc(courseNameEdit)">Save</button>
</form>
and your controller must contain something like this:
$scope.activeDisable = false;
$scope.change = function(){
$scope.activeDisable = true;
}
I have been trying for a while to find out information on how to use angular validation to display messages but with the specific min or max attribute.
If I have an input[type="number"] field with attributes like min=1 or max=10 and the user enters 11 I want a validation message that says: "The number should be less than 10". But the number 10 should be taken from the max attribute dynamically.
I'd like to have the messages in a separate template.
I have the following:
<!-- default ng-messages -->
<script type="text/ng-template" id="common-messages">
<span ng-message="required" class="help-block">This field is required</span>
<span ng-message="maxlength" class="help-block">Must be no longer than {{maxlength}} characters</span>
<span ng-message="min" class="help-block">This number must be greater than {{min}}.</span>
<span ng-message="max" class="help-block">This number must be less than {{max}}.</span>
<span ng-message="number" class="help-block">A number is required</span>
<span ng-message="date" class="help-block">A date is required</span>
</script>
and then in a form
<div class="container" ng-controller="app.packaging.PackagingAddController as package">
<form name="packageForm" ng-submit="package.save()" role="form" novalidate class="form-horizontal">
<input type="text" name="packageCount" ng-model="package.model.packageCount" class="form-control" max="10 " />
<div ng-messages="packageForm.packageCount.$error" role="alert" ng-show="packageForm.$submitted || packageForm.packageCount.$touched" ng-messages-multiple>
<div ng-messages-include="common-messages"></div>
</div>
</form>
</div>
The problem is that the error shown is This number must be less than . so the {{max}} is not being injected. Is there any way to achieve this so that I can reuse the common-messages template?
PS: This thread How to get min and max values of input angularjs is not useful for my question since it does not reuse a template nor it reads from the html input max attribute.
How to validate using ng-messages like ng-maxlength when the <textarea> has a ui-tinymce attribute?
Or is there a better way?
<div class="form-group">
<div class="col-sm-12">
<label>Description</label>
<p class="small">Please provide as much detailed information as possible.</p>
<textarea name="description" class="form-control required" ui-tinymce="tinymceOptions" ng-model="aC.testData.description"
ng-maxlength="100" required></textarea>
<div class="help-block" ng-messages="mainForm.description.$error" ng-show="mainForm.description.$touched">
<p ng-message="required">A description is required.</p>
<p ng-message="maxlength">Description must not exceed 100 characters.</p>
</div>
</div>
</div>
The issue you are seeing is that the standard directives just count characters so a simple (empty) HTML sample:
<p></p>
Would indeed show as 7 characters when in reality there is no "visible" content. I built a custom directive for another editor and what I ended up doing is using jQuery's .text() function against the HTML. This removes all of the HTML tags and provides an approximation for the number of actual text characters in the editor. This is a portion of the code in the diective:
var jStrippedString = jQuery(modelValue).text().trim();
return (maxlength < 0) || ngModelCtrl.$isEmpty(jStrippedString) || (jStrippedString.length <= maxlength);
I believe that you would want to create a custom Attribute directive that allows you to grab the model data for the editor and perform this validation yourself.
Adding forced_root_block: "" to the tinymce options should also work. By default it will not add <p></p> from the start.
I have a form with input fields generated with an ng-repeat. The field names are set dynamically from the model. I cannot get validation to work.
Here is the input field that is repeated within ng-repeat:
<input class="form-control input" type="number" id="item.id" name="item.name" ng-change="ctrl.updateSub(item)" ng-model="item.qty" max="item.maxqty" min="0">
I am trying to validate against the max value, which is also set dynamically.
What I cannot find anywhere is how to set the name within the ng-show classes.
<div class="col-sm-2 error" ng-show="form.{{item.name}}.$invalid">
<small class="error" ng-show="form.{{item.name}}.$error.max">
You exceeded the maximum allowed
</small>
</div>
How am I supposed to handle the {{item.name}} bit?
Thanks in advance for any help or pointers.
Angular 1.3.12
Firstly form is a reserved keyword, you cannot use that as your form name.
Coming to your problem, unfortunately as of right now it is not possible to generate dynamic names for form inputs.
You can achieve what you want with the help of ng-form
Have a look at this example :
<form name="yourForm" >
<div ng-repeat="field in fields" ng-form="myInnerForm">
<input type="text" name="dynamic_input" ng-model="field.name"/>
<div ng-show="myInnerForm.dynamic_input.$dirty && myInnerForm.dynamic_input.$invalid">
The field is required.
</div>
</div>
</form>
I am trying to submit the form on only successful validation.
validation is working for required but not working for ng-minlength
form input is invalid but form is still being submitted.
<form name="myForm" ng-submit="count = count + 1" ng-init="count=0" ng-app>
<div class="control-group" ng-class="{error: myForm.mobile.$invalid}">
<label class="control-label" for="mobile">Mobile</label>
<div class="controls">
<input type="text" name="mobile" placeholder="07XXXXXXXXX" ng-model="mobile" ng-minlength="11" required />
<span ng-show="myForm.mobile.$error.required" class="help-inline">Required</span>
<span ng-show="myForm.mobile.$error.minlength" class="help-inline">Mobile number should be minimum 11 character starting from 07</span>
</div>
</div>
<div class="control-group">
<div class="controls">
<input class="btn" type="submit" value ="submit" />
</div>
count: {{count}}<br />
<tt>myForm.$invalid = {{myForm.$invalid}}</tt><br/>
</div>
</form>

what am I doing wrong.
I don't want to use submit button disable method.
This is what you are doing wrong: you are mixing two concepts, Angular validators and
HTML5 validators.
The required HTML5 validators, for instance, states that:
When present, it specifies that an input field must be filled out before submitting the form.
So, if you try to submit a form that has an input with this attribute, it will show a message explaining this to the user, and it will prevent the form from being sent. This is the behavior you want. Why isn't working for ng-minlength? Because ng-minlength is an Angular validator (you can tell because it begins with ng-), and it doesn't add any special behavior to the form. It simply set the input where it is located to invalid (and hence, the form), and let you decide what to do with it.
You have an option: you can use the pattern HTML5 validator, to specify the field requires at least 11 characters. It would like this:
<input type="text" pattern=".{11,}">
So when you submit a form containing this input, it will no be sent if the user has enter less than 11 characters.
But since we are it, and you are already using the pattern validator, you could use the regular expression in its full potential, and define something like:
<input type="text" pattern="07[0-9]{9}" />
Which will only admit values of 11 characters, that start by "07" and that contains only digits. I have modified your fiddle to show you how it would work: http://jsfiddle.net/helara/w35SQ/
I mistakenly used ngMaxlength="12" ngMinlength="6" instead of ng-minlength="6" ng-maxlength="12", it's working fine now.
Both ng-minlength & mg-maxlength works in AngularJS.
I've tested this in AngularJS version 1.3.
Make sure to use novalidate with <form> to disable browser's native validation.
This should work:
To enter mobile number
ng-show="myForm.mobile.$touched && myForm.mobile.$error.required"
For minimum length
ng-show="myForm.mobile.$touched && myForm.mobile.$error.minlength"
For maximum length
ng-show="myForm.mobile.$touched && myForm.mobile.$error.maxlength"
This work for me guys
<div class="mdl-textfield mdl-js-textfield mdl-textfield--floating-label">
<input ng-minlength="11" class="mdl-textfield__input" type="text" name="cpf" id="cpf" ng-model="avaliacao.cpf" ng-required="true" ng-pattern="/^\d+$/">
<label class="mdl-textfield__label" for="cpf">CPF *</label>
</div>
<p style="color: #d50000;" ng-show="myForm.cpf.$error.required && myForm.cpf.$dirty">Field Required</p>
<p style="color: #d50000;" ng-show="myForm.cpf.$error.pattern">Only numbers</p>
<p style="color: #d50000;" ng-show="myForm.cpf.$error.minlength">Min 11 Chars</p>
I'm facing the same issue, and I think you can only disable the button or ignore the entered value by yourself. You can also check the $valid property in your controller and ignore the value... It is not so nice, but I found no other way.
