As I delve into learning angular JS, I am facing a challenge. I want to disable the button using the "ng-disabled" attribute while my input fields for "login" and "password" are empty. However, the default text in the login input is "LOGIN" and in the password input is "PASSWORD", which means that the inputs always appear as if they are filled...
Seeking assistance,
Thank you
Instead of filling it with content, why not utilize a placeholder?
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.pass = ""; // keeping it empty instead of "PASSWORD"
$scope.foo = () => {
console.log($scope.pass);
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<input placeholder="PASSWORD" ng-model="pass">
<button ng-click="foo()" ng-disabled="!pass">Sign in</button>
</div>Here's another instance tailored to your needs. This example allows you to enter text while keeping the button disabled. It employs ng-focus to clear the input field when selected and includes $dirty validation for enabling the button only if modifications have been made.
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.pass = "PASSWORD";
$scope.foo = () => {
console.log($scope.pass);
};
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.4/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<form name="form">
<input ng-focus="pass=''" name="pass" ng-model="pass">
<button ng-click="foo()" ng-disabled="!form.pass.$dirty || !pass">Sign in</button>
</form>
</div>Here's the script I am working with: $('.how-we-do-it .items div').on('click', function () { var $matchingDIV = $('.how-we-do-it .sections .section .content div.' + $(this).attr('class')); $matchingDIV. ...
