Angularjs ng hide directive

The ng-hide directive in AngularJS is used to conditionally hide an HTML element based on an expression. When the expression evaluates to true, the element is hidden by setting its display CSS property to none. When the expression evaluates to false, the element is shown by setting its display CSS property to its default value.

Here is an example of using ng-hide:

<div ng-hide="showElement">
  This element is hidden.
</div>

In this example, the ng-hide directive is bound to an expression called showElement, which could be a boolean value or an expression that evaluates to a boolean value. When showElement is true, the div element is hidden.

You can also use the ng-show directive to conditionally show an element when the expression evaluates to true. The ng-show directive works in the opposite way of ng-hide, by setting the display CSS property to none when the expression is false.

Here is an example of using ng-show:

<div ng-show="showElement">
  This element is shown.
</div>

In this example, the ng-show directive is bound to the same expression as in the previous example. When showElement is true, the div element is shown.

You can also use the ng-if directive to conditionally create or remove an element from the DOM based on an expression. The ng-if directive completely removes the element from the DOM when the expression evaluates to false, unlike ng-hide and ng-show which only hide or show the element.

Here is an example of using ng-if:

<div ng-if="showElement">
  This element is created and added to the DOM.
</div>

In this example, the ng-if directive is bound to the same expression as in the previous examples. When showElement is true, the div element is created and added to the DOM. When showElement is false, the div element is completely removed from the DOM.
