Conceal the header and footer during the loading of particular pages

For my Angular 1.x application, I needed a way to hide the header and footer on specific pages. To achieve this, I added a 'navigateOut' data property to my state definitions. Using ng-if in my template, I was able to show/hide elements such as the header and footer based on the value of this property. However, I encountered an issue where these elements would briefly appear when the page was loading because the state had not yet been set.


.state('signup', {
    url: '/signup',
    template: require('partials/sso.html'),
    controller: 'SignupController as signup',
    data: {
      navigateOut: false
    }
})


<app-footer ng-if="$state.current.data.navigateOut !== false"></app-footer>
javascriptangularjs

Answer №1

Consider placing the ng-if condition within a div tag instead of directly within the app-footer tag like this:

<div ng-if="$state.current.data.navigateOut !== false">    
<app-footer ></app-footer>
</div>

Another option is to utilize ng-class with the 'hidden' class to hide the element, rather than using ng-if or ng-show/ng-hide.

Answer №2

To enhance efficiency, consider implementing a distinct template and controller for both the headers and footers. Utilize multiple ui-views categorized under header, footer, and content to streamline state loading processes.

If difficulties persist, it may stem from the ng-animate library, which is typically enabled by default. Attempt to disable this feature to resolve any ongoing issues.

<div ui-view="header"></div>
<div ui-view="content"><!-- Content --></div>
<div ui-view="footer"></div>

$stateProvider
    .state('myapp', {
        views: {
          'header': {
            template:'header.html',
            controller:'HeaderController'
          },
          'content': {
            template:'content.html'
          },
          'footer': {
            template:'footer.html',
            controller:'FooterController'
          }
       }    
})
