1. ng-hide and ng-show

  • ng-hide directive

It shows the element when the expression is false, otherwise, it hides it.

Syntax –

  • ng-show directive

It is just opposite of ng-hide directive, it shows the element when the expression is true, otherwise, it hides it.

Syntax –


For example, let’s use both directives in one example, and create 4 span elements. Add ng-show directive in first two and ng-hide in next two spans and run the program.

When you run it in the output you will see span elements with ng-show directive will show only which contains true expression and in ng-hide, it’s just opposite happening.

Here, is the completed code with an Output-

Completed Code

<!doctype html>
<html ng-app=''>
 <title>ng-show and hide directives in AngularJS</title>
 <script src="" type='text/javascript'></script>
 <body > 
 <h3>ng-show directive</h3>
 <span ng-show="true">ng-show with true expression</span><br/>
 <span ng-show="false">ng-show with false expression</span><br/> 
 <h3>ng-hide directive</h3>
 <span ng-hide="true">ng-hide with true expression</span><br/>
 <span ng-hide="false">ng-hide with false expression</span> <br/>



2. Creating Tab Structure

Let’s create a simple tab structure, within the example, we will  using only ng-show directive. Using this we will show or hide the <div> element based on click.

In the example, we have a main container which contains the unordered list which we are using for tab header and for holding tab content we created 3 divs.

Define a tab variable and initialize it with 1 using ng-init with <div class="tabs-container"> and we are changing the tab value when unordered list item gets clicked (ex- ng-click="tab = 1" ).

Using ng-show directive in <div >  which contains an expression.
