离子框架中的选项卡

Question

I am currently facing some issues related to ionic-tabs and Floating tabs concept.

Currently using ionic framework..I am building a mobile app in which I want tabs to get fixed below header once the page is scrolled till the position where the tab is. I have kept ion-tabs inside ion-content.

After getting the scroll position I have added a class "fixed". As it adds the class fixed,the background changes to white (no content visible) and the tabs get hidden instead of getting fixed at the position below header.

$scope.onScroll = function() {

    var scrollWidth = $(".bar".height() + $(".maincontent".height(); console.log($ionicScrollDelegate.getScrollPosition()); console.log(scrollWidth);
          if (parseInt($ionicScrollDelegate.getScrollPosition().top) > scrollWidth) {

            $('ion-tabs').addClass('fixed');
          } else {
            $('ion-tabs').removeClass('fixed');
          }
        };

.fixed {
  left: 0;
  top: 44px;
  position: fixed;
  z-index: 100;
  width: 100%;
}

<ion-view>
  <ion-header-bar class="bar bar-positive">
  </ion-header-bar>

  <ion-content on-scroll="onScroll()">
    <div class="main-content">

      <!-- some content here -->

    </div>
    <ion-tabs class="tabs-icon-top tabs-color-active-dark tabs-background-positive tabs-striped tabs-top">
      <!-- About Tab -->
      <ion-tab title="About">
        <ion-nav-view>
          <div>
            <!--some tab content -->
          </div>
        </ion-nav-view>
      </ion-tab>

      <!--update Tab -->
      <ion-tab title="Updates">
        <ion-nav-view animation="slide-left-right">
          <ion-view>
            <ion-content scroll="false">

              <!-- some other tab content -->

            </ion-content>
          </ion-view>
        </ion-nav-view>
      </ion-tab>
    </ion-tabs>
  </ion-content>
</ion-view>

I have been playing with the ionic.css file and I found a solution for fixed tabs, but like I say you will have to edit the ionic.css file.

You must edit this:

.tabs-top.tabs-striped
{
   padding-bottom: 0;
   position: fixed;
   z-index: 9999
}
.tabs-top > .tabs, .tabs.tabs-top 
{
  top: 44px;
  padding-top: 0;
  background-position: bottom;
  border-top-width: 0;
  border-bottom-width: 1px;
  position: fixed;
  z-index: 9999 
}

With this you will have the ion-tabs fixed, but if you want that bar-header will also be fixed, then edit this

.bar-header 
{
  top: 0;
  border-top-width: 0;
  border-bottom-width: 1px;
  position: fixed;
  z-index: 9999 
}
