I'm currently working on a unique AngularJS Ionic Meteor application, and I am in search of a method to dynamically change the background color of the bottom box within an ionic card based on specific float values. The criteria for color changes are as follows:
data<=80
81 < data <= 160
161 < data <= 233
234 < data<= 317
318 < data <= 400.
Are there any CSS or AngularJS techniques available to achieve this functionality?
To apply conditional styling in AngularJS, you can utilize the ngClass directive. Define your CSS classes with desired background-color properties and use them based on certain conditions set in your controller. Here's an example:
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
$scope.submit = function() {
if ($scope.data <= 80) $scope.rangeColor = "red";
// Add more conditional statements here
else $scope.rangeColor = "blue";
}
}.card {
border-style: solid;
}
.red {
background-color: red;
}
.blue {
background-color: blue;
}<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp">
<div ng-controller="MyCtrl">
<h4>Data:</h4>
<form ng-submit="submit()">
<input type="text" name="data" ng-model="data" required>
<input type="submit" id="submit" value="Submit" />
</form>
<br />
<div ng-class="rangeColor" class="card">
<div class="item item-text-wrap">
This is a basic Card which contains an item that has wrapping text.
</div>
</div>
</div>
</body>Alternatively, you can directly implement the conditional statements in your HTML elements like so:
var myApp = angular.module('myApp', []);
function MyCtrl($scope) {
}.card {
border-style: solid;
}
.red {
background-color: red;
}
.blue {
background-color: blue;
}<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<body ng-app="myApp">
<div ng-controller="MyCtrl">
<h4>Data:</h4>
<input type="text" name="data" ng-model="data" required>
<br />
<br />
<div ng-class="{'red': data <= 80, 'blue': data > 80}" class="card">
<div class="item item-text-wrap">
This is a basic Card which contains an item that has wrapping text.
</div>
</div>
</div>
</body>If you're looking to style elements dynamically in AngularJS, you have a couple of options:
ng-style
For more information on how to use ng-style, check out the official documentation here.
Alternatively, you can also use
ng-class
