I created this simple game where a user is trying to guess a number. I want to use AngularJS frameworks but I am lacking on the basic concepts. For example the first part of my code is a a function that will be used to append the guess to a list of guesses. My issue here is I am not sure how to append to a scope in AngularJS. Here is that part of my original code
var numOfAttempts = 6;
var numOfGuesses = 0;
var numberToGuess = "Three";
function listWordsUsed(numberAttempted)
{
var userTrials = $('#userGuesses');
var divisor = $("<p id ='line'><div class='answers'>" + numberAttempted + "</div></p>");
divisor.hide().appendTo(userTrials).fadeIn(6000);
return;
} //End of function listWordsUsed(numberAttempted)
I know that I will have to make my variables scopes in order to be used by my aplication, like this
$scope.numOfAttempts = 6;
$scope.numOfGuesses = 0;
$scope.numberToGuess = "Three";
However I am not sure how to append to a scope variable in AngularjS. Any suggestions? Hints? By the way here is my HTML as I started setting it up.

Here's a Plunkr
Basically you just build an array of the guesses you list it with ng-repeat. The rest is just count with .length(), and then do basic math right in the interpolated HTML.
<div ng-controller="numberController">
<h3>Enter the number:</h3>
<input type="text" ng-model="guess" />
<p>Guess is: {{guess}}</p>
<button ng-click="addGuess()">Guess</button>
<h3>Your guesses so far are: <span>{{guessed}}</span></h3>
<ul>
<li ng-repeat="g in guesses">
<p>{{g}}</p>
</li>
</ul>
<p>You have guessed: <b>{{guessed}}</b> times out six({{allowed}}) chances.</p>
<p>You have <b>{{allowed - guessed}}</b> guesses left.</p>

I am new to AngularJS. I'm trying to toggle a modal into view using ng-if and ng-click.
Essentially, in my controller, I have a scoped variable called "aboutOn". When it is true, the modal is displayed. When it's false, it's not. Simple.
The ng-if part works. But the ng-click part is causing trouble. Sometimes, it just doesn't work.
To open the modal I have this:
<div id="about-link-container" ng-click="aboutOn=true">
<p><i class="far fa-info-circle"></i> About</p>
</div>
This does not work how I want it to work. If I click on the actual text, nothing happens. It only triggers when I click around the border, not directly on the link. If I put the ng-click on the p tag, it doesn't work at all.
Then inside the modal, I have this to close it:
<div class="about-close">
<i class="fas fa-times about-close-icon" ng-click="aboutOn=false"></i>
</div>
This doesn't work at all. What's going on here? Here is my controller, if that's possibly related:
angular.module('myApp', [])
.controller('myController', ['$scope', function myController($scope) {
$scope.female_name = "female name";
$scope.position = "position";
$scope.tedious_task = "tedious task";
$scope.dirty_task = "dirty task";
$scope.female_name = "female name";
$scope.celebrity = "celebrity";
$scope.useless_skill = "useless skill";
$scope.aboutOn = false;
}]);
Here is the entire view:

There are two problems that give you this issue.
ng-if creates its own scope.
So if you want to reach controller's scope, you need to have ng-click="$parent.aboutOn=false"
FA icons replace DOM (?). You cannot have ng-click on an icon.
Wrap your icon with <div> (as you already do) and put ng-click on it
The code that you need to change, from this:
<div class="about-close">
<i class="fas fa-times about-close-icon" ng-click="aboutOn=false"></i>
</div>
to this:
<div class="about-close" ng-click="$parent.aboutOn=false">
<i class="fas fa-times about-close-icon"></i>
</div>
The default hide directive with angular-formly is ng-if which can be configured via e.g. the formlyConfigProvider.
Currently all my fields should always be shown and I don't want to have unneccesary ng-if="!field.hide" checks rendered that can inpact the performance.
How can I tell formly not to use this check per field/form or globally?
ng-if add and remove elements from the DOM, when you want to show and hide large number of elements it can be slow, insted you can use ng-show.
ng-show will only change the visibility of the element.

you set hide-directive="ng-show" in the formly-form
<formly-form hide-directive="ng-show"></formly-form>
"hide-directive
Allows you to control the directive used to hide fields. Common value for this might be ng-show. It will be passed !field.hide. You can also specify this on a global level using formlyConfig.extras.defaultHideDirective = 'ng-show'"
http://docs.angular-formly.com/docs/formly-form
So you can either set it as I instructed or you can choose to edit it in the config on startup for all fields
I've been trying to trigger a validation error on <md-contact-chips> for ng-minlength/maxlength/required but haven't been able to implement this effectively.
Is there a straight forward way to implement this myself? -- it seems for some reason that the contact chips directive in Angular Material does not support these validations.
See codepen here:
http://codepen.io/anon/pen/YqdRNw
<form name='myForm'>
<div ng-controller="ContactChipDemoCtrl as ctrl" layout="column" ng-cloak="" class="chipsdemoContactChips" ng-app="MyApp">
<md-content class="md-padding autocomplete" layout="column">
<md-contact-chips ng-model="ctrl.contacts" ng-minlength='1' ng-required='true' ng-maxlenght='3' name='contacts' md-contacts="ctrl.querySearch($query)" md-contact-name="name" md-contact-image="image" md-contact-email="email" md-require-match="true" md-highlight-flags="i" filter-selected="ctrl.filterSelected" placeholder="To" >
</md-contact-chips>
<p ng-show="myForm.contacts.$error.required" class="text-danger">You did not enter a contact</p>
<p ng-show="myForm.contacts.$error.minlength" class="text-danger">Your contact list is too short</p>
<p ng-show="myForm.contacts.$error.maxlength" class="text-danger">Your contact list is too long</p>
</md-content>
</div>
</form>
You cannot use this attribute directly. you have to use custom validation for it.
<md-contact-chips ng-model="ctrl.contacts" md-transform-chip="customvalidation($chip)"> </md-contact-chips>
<p ng-show="ctrl.contacts.length == 0 && ctrl.contacts.$touched"> Required </p>
<p ng-show="ctrl.contacts.length < 3 && ctrl.contacts.$touched"> Minimum 2 Contacts are required </p>
<p ng-show="ctrl.contacts.length > 5 && ctrl.contacts.$touched"> Maximum 5 Contacts can be added </p>
Inside controller you can define customvalidation function and add extra condition if you want.
function customvalidation(chip){
if(satisifedCondition(chip)){
return null //It will add chip
} else { return undefined } // It will not add chip
}
For the time being, you will need to write your own validation. Currently, md-chips only supports md-max-chips validation. Other forms of validation are currently pending. md-chips api
You can use the chips length property to get the number of chips in the array. With this you can use ng-show on your error messages to perform the necessary validation checks.
Ex: ng-show="myForm.contacts.length == 0"
Additionally, you can use md-on-add or md-on-remove to write your own validation.
Thats the how can I handle required validation with md-chips and md-contact-chips
I don't test code completely but I wrote that for give you an idea. I hope it helps you !
angular.module('MyApp', ['ngMaterial'])
.controller("ContactChipDemoCtrl", ['$scope', function ContactChipDemoCtrl($scope) {
$scope.formRequiredError = {};
$scope.sendButton = function(form) {
$scope.formRequiredError = {
"required": $scope.contacts.length <= 0;
};
};
}]);

<div ng-messages="formRequiredError">
<div ng-message="required" translate='form_user_empty'></div>
</div>
</div>
</form>
</body>
</html>
Simple workaround:
<md-contact-chips
ng-class="{'myError': object.fieldName !== undefined && object.fieldName.length == 0}"
ng-model="object.fieldName"
otherStuff></md-contact-chips>
In CSS
.myError input::placeholder {
color: rgb(221,44,0) !important;
}
So I'm trying to zebra stripe my ng-repeat so the rows can be easily distinguished.
I think I have everything wired up correctly, but the classes just aren't being applied.
I've created a plunker here.
My html looks like this:
<div ng-repeat="removal in removals" ng-class-even="even" ng-class-odd="odd" class="remove-relation-titles-list">
<div class="pull-left relation-titles-left-list">
<span class="acct-title acct-num">{{removal.AcctType}} {{removal.AcctNo}}</span>
<span class="acct-title"> - Standard Checking</span>
</div>
</div>
So, the regular class is being applied just fine, but the even and odd ones aren't at all. If you inspect the object and add the even class yourself, it shows up beautifully. I've tried moving this down to the div inside the ng-repeat with no results.
Am I missing something obvious?
Change your ng-class to:-
ng-class="{'even':$even,'odd':$odd}"
Plnkr
$even and $odd are the properties added by ng-repeat on its scope.
or change it to take string value of the class names otherwise it will try to replace the class based on the property even or odd which does not exist:-
ng-class-odd="'odd'" ng-class-even="'even'"

First of all, if your page is in an iframe, you need to switch to the frame first.
Given the html from comment as below:

Multiple ways of finding the Gmail link:
driver.FindElement(By.CssSelector(".hdtb_mitem > a[href='gmail.com']")).Click();
// alternatives:
// driver.FindElements(By.CssSelector(".hdtb_mitem > a"))[1].Click();
driver.FindElement(By.XPath("//div[#class='hdtb_mitem']/a[#href='gmail.com']")).Click();
// alternatives:
// driver.FindElement(By.XPath("//div[#class='hdtb_mitem']/a[text()='Gmail']")).Click();
// driver.FindElements(By.XPath("//div[#class='hdtb_mitem']/a"))[1].Click();
// driver.FindElement(By.XPath("(//div[#class='hdtb_mitem']/a)[2]")).Click();
ANother XPath approach would be to search 'by text' as the contained text appears to be the only truly unique identifier (this is generally not ideal, but it appears you don't have control of the HTML in this case).
driver.FindElement(By.XPath("//div[#class='test1']/a[contains(text(), 'Images2')]")).Click();
IWebElement elment = driver.FindElement(By.PartialLinkText("Click"));
element.Click();
