Show input file name in DOM using AngularJS - angularjs

I am trying to show the input file name in a readonly text box.
As can be seen this is different from the custom input file of HTML.
So, I tried this.
<input type="text" readonly ng-model="name">.
<input style="display: none" id="upload" type="file" accept=".csv" onchange="angular.element(this).scope().fileNameChange(this)">
<button type="button" ng-click="clickUpload()">Browse</button>
$scope.fileNameChange = function(e) {
$scope.name=e.files[0].name
}
$scope.clickUpload = function(){
angular.element('#upload').trigger('click');
};
With this logic, say I first select 'inputFile1.csv', nothing is shown in the textbox.
Then I select another file 'inputFile2.csv', now 'inputFile1.csv' is shown in textbox.
Where am I going wrong? Also, is this the best way to implement this functionality?

Try this:
<input type="text" readonly ng-model="name">.
<input style="display: none" id="upload" type="file" accept=".csv" onchange="angular.element(this).scope().fileNameChange(this)">
<button type="button" ng-click="clickUpload()">Browse</button>
$scope.fileNameChange = function(e) {
// let the DOM process before letting angular do its thing
$timeout(function() {
$scope.name=e.files[0].name
});
}
$scope.clickUpload = function(){
angular.element('#upload').trigger('click');
};

Reset form after ng-Submit and suppress ng-messages

I have a form which when I submit, I reinitialise it as the form has been submitted. I then show a message and stay on the same page.
However, the form's fields come up with the error messages as the form has been "touched".
Demonstrated below:
I have read some articles about how to go around this but none are working for me.
My HTML:
<form name="newPost" ng-submit="makeNewPost()">
<div class="form-group">
<input name="title" maxlength="46" minlength="2" type="text" class="form-control" ng-model="post.title" required="required">
<div ng-messages="newPost.title.$error" ng-if="newPost.title.$touched">
<div class="errorMessage" ng-message="required">Title is mandatory *</div>
</div>
</div>
<input type="submit" value="Submit" class="btn btn-success" id="submit">
My controller code to reset the data:
var resetData = function(){
$scope.post = {};
};
resetData();
Of course there are more fields but to solve the problem, just this simple code will demonstrate it.
Any input will help. Thanks chaps!
Your resetData function should be:
$scope.resetData = function(){
$scope.post = {};
$scope.newPost.$setUntouched();
$scope.newPost.$setPristine();
}
where newPost is form name & $setUntouched, $setPristine will make form pristine just like initially loaded. Call this function in the end of submit function.

angular ionic - form submit with button that is not located within the form tags

I’m using a library called floating-tabs.js which is being used to create floating navigational buttons: here’s an example of what the layout looks like
<floating-tabs>
//this is my button
<floating-tabs-item icon="ion-android-arrow-dropright-circle" click="goNext(data)"></floating-tabs-item>
</floating-tabs>
<ion-content>
<form name=“formName” ng-submit="goNext(data)">
***form stuff
</form>
</ion-content>
How can I submit/validate the form without having my button inside the form tags
Thanks guys
here i am using simple change password form.
<form name="changepasswordform" novalidate>
<input type="password" placeholder="New Password" class="reset-inputs" name="newpassword" ng-keyup="compare()" ng-model="changePassword.newpassword" maxlength="10" required/>
<span style="color:red" ng-show="submitted && changepasswordform.newpassword.$error.required">Required</span>
</form>
<button type="button" class="reset-submit" ng-click="changepassword(changepasswordform.$valid,changePassword)">Change Password</button>
it consist button out side the form
and please use the script in your controller
$scope.submitted = false;
$scope.changepassword = function(formValidStatus, formdata) {
if (!formValidStatus) {
$scope.submitted = true;
} else {
$scope.submitted = false;
}
}
in the script i am checking form is valid or not if form is not valid i am showing error messages by using submitted variable from script.
This works for me

Error message does not hide after angular form validation

This is my form my HTML
<form id = "myform" name="myform" ng-submit="saveForm()" novalidate >
<div class="input-group">
<span class="input-group-addon"> <img src="/icon.png" alt=""/> </span>
<input type="text" class="form-control" id="username" name="username" ng-model="username" placeholder="Username" autofocus required>
</div>
<span ng-show="formInvalid">Please enter username</span>
<button type="submit" class="btn btn-default" id="saveBtn"> Save </button>
</form>
And inside the controller I have
$scope.formInvalid = false;
$scope.saveForm = function(){
if($scope.myform.username.$invalid){
$scope.formInvalid = true;
}
if($scope.myform.$valid){
//....save it....
At first the form has no error message, if I hit "Save" the "Please enter username" appears, so far, all good.
But if I click on the form field to type a username, the error message does not go away. Even if I finish typing and click somewhere else, the error message still does not go away.
I also try
if(!$scope.myform.username.$valid){
$scope.formInvalid = true;
}
and I also try together
if(!$scope.myform.username.$valid){
$scope.formInvalid = true;
}
if($scope.myform.username.$valid){
$scope.formInvalid = false;
}
and the problem is still there. How can I debug? How do I fix this?
Thanks
You don't have to introduce and maintain a new variable ($scope.formInvalid) for managing the state of your form. Angular maintains the valid / invalid state of the form for you.
As your form is named myform, just show the message about the username based on the value of myform.username.$invalid, and save the form only if myform.$valid is true:
HTML
<span ng-show="myform.username.$invalid">Please enter username</span>
JS
$scope.saveForm = function () {
if ($scope.myform.$valid) {
// save the form
}
};
See fiddle
you can try a watch event,
$scope.$watch('myform.$valid', function(n, o) {
if(n) {
$scope.formInvalid = false;
} else {
$scope.formInvalid = true;
}
});
But i might even be a better idea, if you start using validators.
you do not trigger a change to form invalid property anywhere, I suggest you solve this issue with angulars built in validators and ng-messages module, which will listen to changes on you're form inputs and notify when the inputs are valid or invalid and notify the warning text.
Another approach you can take is use the ng-change directive on the inputs you want to listen to changes in and trigger and update on the form invalid property according to the inputs validity.
example : (taken from the official angular website )
<form name="myForm">
<label>
Enter your name:
<input type="text"
name="myName"
ng-model="name"
ng-minlength="5"
ng-maxlength="20"
required />
</label>
<pre>myForm.myName.$error = {{ myForm.myName.$error | json }}</pre>
<div ng-messages="myForm.myName.$error" style="color:maroon" role="alert">
<div ng-message="required">You did not enter a field</div>
<div ng-message="minlength">Your field is too short</div>
<div ng-message="maxlength">Your field is too long</div>
</div>
</form>
i think this is the most elegant way to do it.

Call the first <span> in a scrollbar when press enter using angularjs

I have a text box which is using for search.When enter the characters it searches the values and shows one by one in a scrollbar. When i click on any found value it redirects to the related page but when press enter it should call first value in that scrollbar.Below is my code.
<div><input type="text" value="" placeholder="search" ng-model="searchText" name="testName" ng-keyup="search()"></div>
<div class="scroll" ng-show="searchText.length" ng-hide="!searchText.length">
<div ng-repeat="relatedData in data">
<span ng-click="showDetails(relatedData)" ng-model="searchText">{{ relatedData }} </span><br />
</div>
</div>
and below is my script code:
$scope.showDetails = function(relatedData) {
$http.get("searchInfo.json").success(function(response) {
var searchT = relatedData;
$http.get(searchT+'Details.json').success(function(response) {
$scope.details = response;
$scope.searchText = "";
});
});
}
Could you please help to call first value in multiple values scrollbar,Thanks.
One way would be to wrap your search field in a form element:
<form ng-submit="showDetails(data[0])">
<input type="text"
value=""
placeholder="search"
ng-model="searchText"
name="testName"
ng-keyup="search()">
</form>
ng-submit will catch the form submit event triggered by pressing Enter.

Angular form name is passed as string when passed as parameter

I'm simply trying to reset a form using the angular functions $setPristine & $setUntouched (several forms are created with ng-repeat).
I assign the form name dynamically by using the syntax {{ someName }} (the name is build on the server side and is passed as json (string)).
The name of the form is correctly assigned in the markup and validations are working as expected. The problem arrises when I pass that name as a parameter in the ng-click="reset(someName)" function.
When debugging the name comes as a string and not as the form object which causes the error. I did a quick test by hard-coding the name and pass that same name and it works fine.
My assumption is, the name coming from json is a string and the type is forwarded to the function as is, instead of the object.
So the question is: is there a way to convert that name so it is interpretated correctly by the controller. Or maybe there is something else I'm missing...
Here is the markup ( notice the name of the form uses {{ resto.contactForm }} ):
<form novalidate name="{{ resto.contactForm }}" ng-submit="submit(restoContact, resto.contactForm.$valid)" class="sky-form">
<div class="form-group">
<label class="checkbox state-success">
<input type="checkbox" ng-model="restoContact.sameAsUser" name="sameAsUser" id="sameAsUser" value="true" ng-click="contactAutoFill()"><i></i>Contact name is same as current user.
<input type="hidden" name="sameAsUser" value="false" />
</label>
</div>
<div class="form-group">
<label class="control-label" for="contactName">Contact Name</label>
<input type="text" ng-model="restoContact.contactName" name="contactName" id="contactName" placeholder="John, Doe" class="form-control" required />
<div ng-show="{{ resto.contactForm }}.contactName.$error.required && !{{ resto.contactForm }}.contactName.$pristine" class="note note-error">Please enter a name or check the box 'Same as current user'.</div>
</div>
<div class="form-group">
<label class="control-label" for="contactPhoneNumber">Contact Phone Number</label>
<input type="text" ng-model="restoContact.contactPhoneNumber" name="contactPhoneNumber" id="contactPhoneNumber" placeholder="+1 555-1234-567" class="form-control" required ng-pattern="phoneNumberPattern" />
<div ng-show="({{ resto.contactForm }}.contactPhoneNumber.$error.required || {{ resto.contactForm }}.contactPhoneNumber.$error.pattern) && !{{ resto.contactForm }}.contactPhoneNumber.$pristine" class="note note-error">Please enter a valid phone number.</div>
</div>
<div class="margin-leftM19">
<button class="btn btn-primary">Save Changes </button>
<button class="btn btn-default" ng-click="reset(resto.contactForm)">Cancel </button>
</div>
</form>
Here is the reset function in the controller (form comes as "contactForm1" which is the correct name but is a string and not the object):
$scope.reset = function (form) {
if (form) {
form.$setPristine();
form.$setUntouched();
}
//$scope.user = angular.copy($scope.master);
};
I have not implemented th submit method but I'm sure I will be running into the same issue.
Any suggestions or advices are welcome.
Thanks in advance...
Here is the fidle.js. the variable data is an exact response from the server.
[http://jsfiddle.net/bouchepat/v0mtbxep/]
SOLUTION:
http://jsfiddle.net/bouchepat/v0mtbxep/3/
I removed $setUntouched as it throws an error.
You can't dynamically name a <form> or <ng-form>.
Although what you want, is make the form usable in the controller. You could do the following:
// in controller
$scope.form = {};
$scope.reset = function() {
$scope.form.contact.$setPristine();
$scope.form.contact.$setUntouched();
};
// in html
<form name="form.contact">
This is happening because resto.contactForm is a string defined on the scope. The angular directive for form is just creating a variable on the scope with the same name. To get the variable by a string, use $eval. This should work:
$scope.reset = function (formName) {
var form = $scope.$eval(formName);
if (form) {
form.$setPristine();
form.$setUntouched();
}
//$scope.user = angular.copy($scope.master);
};
