How to make use of ng-if , ng-else in angularJS

All we need is an easy explanation of the problem, so here it is.

I want to compare if id equals 5 do this, else do that.
How can I achieve this?

<div class="case" data-ng-if=" === '5' ">
    <input type="checkbox" id="{{}}" value="{{data.displayName}}"
            data-ng-checked="{{data.status}}=='1'" onclick="return false;">{{data.displayName}}
<div class="case" data-ng-else>
    <input type="checkbox" id="{{}}" value="{{data.displayName}}"

How to solve :

I know you bored from this bug, So we are here to help you! Take a deep breath and look at the explanation of your problem. We have many solutions to this problem, But we recommend you to use the first method because it is tested & true method that will 100% work for you.

Method 1

Use ng-switch with expression and ng-switch-when for matching expression value:

<div ng-switch="">
  <div ng-switch-when="5">...</div>
  <div ng-switch-default>...</div>

Example is here

Angular2 example

Method 2

There is no directive for ng-else

You can use ng-if to achieve if(){..} else{..} in angularJs.

For your current situation,

<div ng-if=" == 5">
<!-- If block -->
<div ng-if=" != 5">
<!-- Your Else Block -->

Method 3

You can also try ternary operator.
Something like this

{{ === 5 ? "it's true" : "it's false"}}

Change your html code little bit and try this hope so it will be work for you.

Method 4

The syntax for ng if else in angular is :

<div class="case" *ngIf=" === '5'; else elsepart; ">
    <input type="checkbox" id="{{}}" value="{{data.displayName}}" 
    data-ng-model="customizationCntrl.check[data.id1]" data-ng-checked="
    {{data.status}}=='1'" onclick="return false;">{{data.displayName}}<br>
<ng-template #elsepart>
    <div class="case">
        <input type="checkbox" id="{{}}" value={{data.displayName}}"  
        data-ng-model="customizationCntrl.check[]" data-ng-checked="

Method 5

I am adding some of the important concern about ng directives:-

  1. Directives will respond the same place where it’s execute.
  2. ng-else concept is not there, you can with only if, or other flavor like switch statement.

Check out the below example:-

<div ng-if=”data.type == ‘FirstValue’ “>

//different template with hoot data


<div ng-if=”data.type == ‘SecondValue’ “>

  //different template with story data


<div ng-if=”data.type == ‘ThirdValue’ “>

 //different template with article data


As per datatype it is going to render any one of the div.

Method 6

<span ng-if="verifyName.indicator == 1"><i class="fa fa-check"></i></span>
<span ng-if="verifyName.indicator == 0"><i class="fa fa-times"></i></span>

try this code.
here verifyName.indicator value is coming from controller.
this works for me.

Method 7

You can write as:

<div class="case" ng-if=" === '5' ">
    <p> this will execute </p>
<div class="case" ng-if=" !== '5' ">
    <p> this will execute </p>

Note: Use and implement method 1 because this method fully tested our system.
