Consider the following HTML snippet:
<p id="message" ng-show="something"></p>
As the page loads, the #message element may be populated with text from an AJAX request.
I want to show or hide #message based on whether it has content or not.
Something similar to:
<p id="message" ng-show="self.text != ''"></p> <!--This code is not functional as-is-->
One effective solution is to link the content of #message to a specific scope variable.
<p id="message" ng-show="Content != ''">{{Content}}</p>
By updating the value of $scope.Content, you can easily modify both the text within #message and its display status.
It's important to note that binding the content of the #message element to a scope variable is the recommended approach, as Feussy pointed out.
If for any reason you are unable or choose not to bind the content to a variable in your Controller, you have the option to directly bind the content on the element itself. This will give you a syntax that aligns more closely with what you're seeking.
<p id="message" ng-bind="self.text" ng-show="self.text !== ''"></p>
