I am using parsley.js, I have native dropdown I have a certain list with a specific value to it, I want to trigger parsley error when value="noValue" (select) is selected.
<select required="true">
<option value="NoValue">Select</option>
<option value="a">A</option>
<option value="b">B</option>
<option value="c">C</option>
<option value="d">D</option>
</select>
so when the user selects "select(value="novalue")" parsley should trigger an error if required="true" and show an error message and append parsley-error class on the select/parsley-success if any other value is selected.
Thanks in advance
Have a look at custom validators - they'll help to achieve that behaviour.
Or...if your option values are really single letters, you can use a regex-pattern such as \w for any single word-character. It will fail for "NoValue".

I see a blank drop down, which I suspect is due to an additional option that gets injected. If I am able to remove this additional option generated, I think, my problem will be solved.
Auto-injected Option:
<option value="? number:1 ?" selected="selected"></option>
My View:
<select id="myValue"
ng-model="myObject.value"
ng-change="foo()">
<option value="0"
localize="MyValue0"
ng-selected="myObject.value === 0"></option>
<option value="1"
localize="MyValue1"
ng-selected="myObject.value === 1"></option>
</select>
How can I conver myObject.value to number? I have tried ng-Model = "parseInt(myObject.value)" and ng-model = "myObject.value | number". Both throw a nonassignable element error. I am using Angularjs 1.6 and moving away from directives, so creating angular.directive function may not be an option
I believe it's Angular best practice to use the ngOptions directive, documented here.
Also, regarding the first option being <option value="? number:1 ?" selected="selected"></option>, I suspect that's because the initial value of myObject.value doesn't match any of the possible options values.
Try this:
<select id="myValue" ng-model="myObject.value" ng-change="foo()"
ng-options="item for item in options">
<option value="" disabled selected style="display:none;">Placeholder</option>
</select>
JSFiddle here showing that myObject.value is a number.
Updated JSFiddle to showcase the dropdown without a placeholder.
I have form and i am showing the input field depending on the select list (if they select tow the input field tow will be showing ) and its work fine
my problem is the text fields are rquired , so if they select one option then the other field related to other options will be hidden , the form is not submitting to database anymore because that hidden fields are required
what is the solution to solve it?
<select ng-model="myDropDown">
<option value="one">One</option>
<option value="two">Two</option>
<option value="three">Three</option>
</select>
<input ng-show="myDropDown=='two'" type="text" required>
thank you
Use ng-if rather than ng-show.
The former removes the field from the DOM, whereas the latter just applies a CSS rule hiding it.
I'm trying to modify a form which is using a select box that is populate NOT using ng-options.
The form itself is bound to an angular controller. Is there still a way for me to know the selected value of the select box even though the select values were not build using ng-options?
I have the following
<select ng-model="country" ng-change="checkValue()"
but the checkValue function isn't even firing, apparently.
Any thoughts?
You don't need to use ng-options to get the selected value. As long as your select element uses ng-model the value will be stored there.
For example:
<select ng-model="mySelectValue">
<option value="1">Option 1</option>
<option value="2">Option 2</option>
<option value="3">Option 3</option>
<option value="4">Option 4</option>
</select>
Now in your controller you would be able to access the value of the select using $scope.mySelectValue.
You should always '.' your scope variables.
$scope.address = {};
Then bind to
ng-model="address.country"
I am new to Angular, I have the following code:
<select id="selectUser" class="form-control" ng-change="selectAction()" ng-model="users"
ng-options="value.SignOnId as value.UserName for value in users">
<option value="">Select a User</option>
</select>
As soon as I select a value from the drop down, it executes the selectAction() method and then all values from the drop down disappear, can anybody tell me what's the reason?
change this: ng-model="users" to ng-model="user"
When you select the user, you are setting the users variable to be the selected user, which means your ng-options no-longer has options in it.
I have a <select> element with an ng-model=sendTime element to select a time from the list. This list contains only a limited number of standard times, but as a last item it always contains an option for the sendTime in the model:
<select ng-model="sendTime" style="">
<option value="now">now</option>
<option value="08:00">08:00</option>
<option value="17:00">17:00</option>
<option value="{{sendTime}}">{{sendTime}}</option>
</select>
The last item is just to ensure that a custom time (which is not editable in this view) will appear in the selection box. The problem is that Angular doesn't do this correctly. It adds the final element to the list, but it doesn't select it. It only ever selects one of the default times.
How can I fix this?
Change the last option to <option ng-value="sendTime">{{sendTime}}</option>. The behavior will be abit weird though. When you select an other option the value of the last option will change to the selected option. If you don't want this behavior you could do something like this:
<select ng-model="sendTime" style="" ng-init="default=sendTime">
<option value="now">now</option>
<option value="08:00">08:00</option>
<option value="17:00">17:00</option>
<option ng-value="default">{{default}}</option>
</select>
