I’ve created a few components that handle form submission functionality. In each of these components, I want the form submit/cancel buttons to be fixed at the bottom of the view, much like the functionality available via ion-footer. The submit button needs reference to the variables + methods in the component for [disabled] + (tap) functionality, for example [disabled]="!formGroup.valid" (tap)="submitForm()"
If the component is a child of ion-content then there is no way to add ion-footer as it will be contained within ion-content, instead of below ion-content. At first glance, having ion-footer inside ion-content appears to view properly, but the rendering can be buggy especially in scroll situations. I went as far as setting a force-bottom css class with fixed position/bottom but it looks like the ionic javascript overrides fixed positioning when inside ion-content, so a pure CSS solution does not seem to be possible.
<ion-content>
<a-form-component>
</a-form-component>
</ion-content>
<ion-footer>
<!-- add a-form-component's button here -->
</ion-footer>
Any recommendations on how to achieve the desired functionality?
TIA
Let's say you have a page called page and a component called cp
inside page.html you have the component <cp></cp>
Inside cp.html you have
<div>anything goes here</div>
<div>anything goes here</div>
<div>anything goes here</div>
<div>anything goes here</div>
<div id="the-footer">
<button>login<button>
</div>
inside page.scss:
#the-footer{
background-color: #efefef;
text-align: center;
position: fixed;
width: 100%;
bottom: 0px;
z-index: 99999;
}
This will achieve the same result as ion-footer.
The div containing the button will always be visible regardless of the scrolling.
hope it helps

I want the user to be able to click and drag the scrollbar on the side of the screen while using my ionic app. Is this possible?
Ionic has a built in component called ion-scroll. It does what you have described and more. You can implement it inside your HTML like so.
<ion-scroll
scrollX="true"
scrollY="true">
</ion-scroll>
For me the solution was to add isBrowser variable to the controller which determined if this is mobile (no scroll bar) or desktop (draggable scrollbar).
<ion-content data-ng-class="{ isBrowserView : appCtrl.isBrowser }"
overflow-scroll="{{ appCtrl.isBrowser }}">
...
</ion-content>
And I added the following to me scss file:
.isBrowserView {
overflow-y: auto !important;
}
.isBrowserView .scroll-bar-indicator {
display: none;
}
*If you always want the scrollbar then do not worry about setting the value on a controller. Like so:
<ion-content class="isBrowserView"
overflow-scroll="true">
...
</ion-content>
I have a page that scrolls, and I want to add a fixed div to the bottom of it in ionic2. I use the ion-fixed, and it works great on android devices staying fixed in the bottom of the page, but on iOS upon scrolling the page, it sort of jumps all the time until get the position.
I am sure someone working in ionic has forced the same issue.
I have tried to detect platform and to use a css tweak of
position: sticky;
and it moves smootly, but I am facing another bouncing issue once you are in the end of the page ( the native over-scroll ios behavior, if you continue to scroll the page from the top or the bottom area).
If you want to place a div in the bottom of the page, fixed, the best way to do it in Ionic is to put that div outside of the ion-content:
<ion-header>
<!-- ... -->
</ion-header>
<ion-content>
<!-- ... -->
</ion-content>
<div class="fixed">
<!-- ... -->
</div>
And then use some css style rules to set its position according to your needs:
div.fixed {
position: fixed;
bottom: 0px;
left: 0;
width: 100%;
z-index: 999
}
Since it's outside of the content, it will be ignored by Ionic during the scroll event.
I have a sliding toggle div that is hidden on page load and when a button is clicked gets revealed. The div is 250px in height and is positioned top 0px. I have also tried bottom 100% which sort of does the same thing. I am using several layers of z-index and have had to position some divs using absolute in order to get the layout I wanted. But I was hoping there is a way to push all of these divs down by 250px when the sliding toggle is revealed. I was thinking that instead of using toggle div, maybe there is a way to scroll the page to -250px so that all the content appears the same but is pushed down?
This is the css for the div I am using in case there is something that can be done here:
#slidingTopBar
{
background:#199651;
display:inline-block;
position: fixed;
height:250px;
width:100%;
left:0px;
top:0px;
z-index:56;
}
The script for the toggle is being used as follows:
$(document).ready(function(){
$("#slidingTopBar").hide();
$(".show_hide").css('position','absolute').show();
$('.show_hide').click(function(){
$("#slidingTopBar").css('position','absolute').slideToggle();
}); });
And the toggle is being called using this html:
<div id="TopBar">SHOW</div>
Which is all working, except it is overlaying the content that is already there whereas I want it to push it all down.
Any help appreciated.
Using the clearfix method directly below the toggle div or it's wrapper should fix this:
HTML: <div class="clearfix"></div>
CSS: .clearfix { clear: both; }
Right now on my website I have the following JavaScript that shows and hides a
<div class="commentBox"></div>
when user clicks a
Show Comments
Full Code:
<script type="text/javascript">
function toggleSlideBox(x){if($('#'+x).is(":hidden")){$(".comentBox").slideUp(200);$('#'+x).slideDown(200)}else{$('#'+x).slideUp(200)}}
</script>
Show Comments
<div class="commentBox">Content</div>
The effect can be illustrated like this:
I wanted to modify this function to act differently, but I couldn't figure it out. Basically what I wanted was to show content that is at the bottom once it starts expanding and have a fade in effect.
This is what I was hoping to achieve:
Could anyone suggest how to achieve the slide / toggle effect that is shown in image 2? so when user clicks a link it expands like that and when link is clicked again it shrinks.
The effect you describe looks just like the JQuery UI slide effect to me (rather than the blind effect that you have at present). This doesn't provide the opacity animation but provides a very simple solution otherwise. Or maybe I am misunderstanding you?
(The method accepts a parameter to slide down, rather than right-to-left of course)
$("#test").show("slide", {direction: "up"}, 1000);
JSFiddle here
If you are just animating a background image, like that rabbit just set the background position like this:
background-position: 0 100%;
This will align the background to the bottom edge rather than the top.
For text content the same principle applies. You just have to position the content absolutely to the bottom edge. For example:
<div class="container">
<div class="content">
<p>Text</p>
</div>
</div>
Then use this CSS:
.container {
position: relative;
overflow: hidden;
}
.content {
position: absolute;
bottom: 0; left: 0;
}
The only issue with this is that you need to find the height of the content so that you know how much to expand the container.
To do this, you can use this jQuery:
var height = $('.content').outerHeight();
Then on the click event just animate to the correct height:
$('.container').animate({
'height': height
});
Hope that helps :)
I have a DIV tag which I can made either
display: none;
or
visibility: hidden;
Then I want to show it with GWT.
But when I am trying to do
RootPanel.get("myid").setVisible(true);
or
RootPanel.get("myid").setVisible(false);
and it has no effect.
I saw in Firebug, that thess functions add "display: none" or remove it in turn. Since there is one explicit "display: none" hardcoded, the DIV is constantly hidden.
So, how can I accomlish the task? Thanks.
In your JSP
<div id="myid" style="display:none ; width:100%">
In your GWT EntryPoint class
DOM.getElementById("myid").getStyle().setDisplay(Display.BLOCK);
