jquery mobile: keeping horizontal control group in one row - jquery-mobile

I have two dynamic horizontal control groups of radio buttons:
<div class="categories-panel" id="sections-panel">
<fieldset id="section-choice-fieldset" data-role="controlgroup" data-type="horizontal">
<!-- ko foreach: Sections -->
<input type="radio"
data-mini="true"
...
/>
<label data-bind="text:Name, attr:{'for':Id}"></label>
<!-- /ko -->
</fieldset>
</div>
The content of controlgroups is updated by knockoutjs. The markup is updated this way:
self.refreshCategoriesList = function() {
$("#section-choice-fieldset").find("input[type='radio']").checkboxradio();
$("#category-choice-fieldset").controlgroup();
};
The problem is: the controlgroups don't fit in one row until I turn of and turn on the display: inline-block property of .ui-controlgroup-controls div in debugger:
before display: inline-block refresh:

after display: inline-block refresh (desired view):

How to make jQM always paint my controlgroups in one row?

First of all, the way you select your control group is wrong in this line :
$("#category-choice-fieldset").controlgroup();
Mustnt it be
$("#section-choice-fieldset").controlgroup();
(Maybe a typo)
You could do this in any of the two ways :
Method 1
Works fine in my fiddle. I'd say you move the <script> tag from head to body because page events of jQM dont play well with KnockOut.js and KnockOut.js needs a DOM ready to work properly, AND DOM ready doesnt work well with jQM. So I guess its a vicious loop indeed.
Demo : http://jsfiddle.net/hungerpain/k7UR5/
Method 2
And you could try one more thing in your refreshCategoriesList method:
//$("#section-choice-fieldset").find("input[type='radio']").checkboxradio();
//$("#category-choice-fieldset").controlgroup();
$("[data-role=page]").trigger("create");
Refreshing the entire controls on the page - thats what trigger("create") does
Demo : http://jsfiddle.net/hungerpain/k7UR5/1/

If you are updating the control group (appending, modifying etc) , access the control group like this:
$("#my-controlgroup").controlgroup("container")["append"]($el);
You need to access the control group container. See my jsfiddle for modifying the control group:

Jquery Mobile: Embed external HTML file without iframe

How can I load a external html page in a div?
<div data-role="page" id="pageone">
<div data-role="panel" id="myPanel">
<!--Load nav.html here-->
</div>
...
I have tried with following code but it doesn't function.
$( "#myPanel" ).load( "nav.html" );
See: http://plnkr.co/edit/N6xTrvLHWdOMG9Lq?open=lib%2Findex.html
The panel is expecting some markup as content, not a whole HTML page.
This will load Your navigation listview inside the panel:
$(document).on('panelcreate', '#myPanel', function () {
$(this).children(".ui-panel-inner").load("nav.html ul", function() {
$(this).enhanceWithin().trigger("updatelayout");
});
});
The full-width listview is requiring some additional CSS:
/* The left reveal panel shadow is 5px inset and blurred by 5px */
.ui-panel-display-reveal.ui-panel-position-left .ui-listview {
margin-right: -10px;
}
EDIT:
To test Your navigation menu and see if it looks as intended, You may design it directly inside the panel. To allow the framework to create the panelInner, simply put somewhat inside the panel div, i.e. a placeholder div or, as said, even better the static version of Your navigation menu. Thus, it will be then correctly replaced by Your external version.
In one word, instead of <!--Load nav.html here--> write <div>...</div>.

jQuery Mobile - Side by side numeric input with a slider

I am using jQuery Mobile. I am attempting to allow the user to change a slider value in two ways. A number, or a percentage. For example, let's say that the total of a metric is $224. So 50% is $112. Well, I want the user to be able to specify $100 manually, OR specify 50% manually.
With this said, I placed a numeric text box and a slider next to each other. The numeric text box appears larger and different from the slider's text box. One thing to note - I have removed the up/down buttons via CSS.
Try as I might, I cannot get these to display the same way. Does anyone know what classes are needed for this? Changes done on pageinit()?
To put elements side by side, use ui-grid layout. For two items, add class ui-grid-a to a div. Then wrap first with div with class ui-block-a and the other one class ui-block-b.
Demo
<form>
<div class="ui-grid-a">
<div class="ui-block-a">
<label for="numbers"></label>
<input type="number" name="numbers" id="number" />
</div>
<div class="ui-block-b">
<label for="slider-6" class="ui-hidden-accessible">Slider:</label>
<input type="range" name="slider-6" id="slider-6" min="0" max="100" value="50" />
</div>
</div>
Optional - Override width of child divs.
.ui-block-a { width: 30% !important; padding-right: 10px !important }
.ui-block-b { width: 70% !important }
For input, you need to adjust input's parent div's height by either jQuery or CSS.
Note: Slider has type=number attribute as well, therefore, you need to override the input box only which has class ui-input-text.
CSS
div.ui-input-text { height: 28px !important }
jQuery
$('[type=number]').closest('div.ui-input-text').css('height', '28px');

Jquery draggable: scrolling in droppable using helper 'clone' and appendTo

I'm suing jquery ui draggable on a list of items that can be dropped on a .droppable list of other items. Here's a jsFiddle to show what I'm trying to do:
<div id="container">
<div id="left-pane" class="pane">
<div class="item">Item A</div>
<div class="item">Item B</div>
<div class="item">Item C</div>
<div class="item">Item D</div>
</div>
<div id="right-pane" class="pane">
<div class="item">Item E</div>
<div class="item">Item F</div>
<div class="item">Item G</div>
<div class="item">Item H</div>
</div>
​
$('.item').draggable({
helper: 'clone',
appendTo: '#contentpane',
cursor: 'move'
});
$('.item').droppable();
The panes have a fixed height, and overflow-y: auto so that we can scroll inside to see hidden elements.
When dragging an element from a list to the other, the lists do not scroll since I use appendTo and the dragged item is not in the list. Is there a way to make the list 'scrollable' when I drag an item over? otherwise it is not possible to drop the item at the bottom of the list, let's say drop 'Item A' on 'Item H' on the fiddle example
Be able to use the scroll features from different container is really not easy to do.
I opended a topic on this subject. You will find an edit of the question with a functionnal workaround.
Check this related question : JqueryUI, drag elements into cells of a scrolling dropable div containing large table
About your last remark, you could place your item at the boom of the list using the sortable property. http://jqueryui.com/sortable/
Well the only way I found to do it is to detect the position of the dragged element and scroll the droppable container, with a smooth effect so that it will scroll like doing it from the mouse wheel.

Dynamic buttons in jQuery Mobile footer?

Dynamically injecting buttons into JQM footers seems to be an exercise in frustration. Anyone have a clue how to apply proper formatting for this? Here are several anomalies I found trying to do this:
Multi-column button grids are not properly formatted in the footer
data-corners="false" attribute (to get flush buttons) does not apply to the first and last buttons in the footer
With data-role="controlgroup" data-type="horizontal" for the footer buttons, if there are too many buttons to fit in one row the styling looks weird (since some buttons will have rounded corners, others will not)
If data-role="controlgroup" data-type="horizontal" are omitted for the footer buttons, buttons may be rendered partially off the screen...
In general - argh!!!! Anyone have any success dynamically injecting buttons into a footer? If so, would much appreciate to hear how this was achieved.
Thanks!
Would something like this work:
http://jsfiddle.net/eznh8/7/
JS
$('#addButtonName').click(function() {
var theFooter = $('#addMoreButtons');
var buttonName= $('#newButtonName');
if(buttonName.val() != '') {
theFooter.append(''+buttonName.val()+'');
buttonName.val('');
$('#theHomePage').trigger('create');
}
});
HTML
<div data-role="page" id="theHomePage">
<label for="basic">Button Name:</label>
<input type="text" name="newButtonName" id="newButtonName" value="" />
Add New button
<div data-role="footer" class="ui-bar" id="addMoreButtons">
</div>
</div>
Multi-column button grids are not properly formatted in the footer - this is my response to that.
One thing to check if you are using controlgroup with a href links - make sure your each of the links in the control group has the following CSS;
vertical-align:top;
You will also have to get more control over how the elements look if you are styling them as buttons. I posted a similar discussion over here:
https://forum.jquery.com/topic/jquery-mobile-horizontal-control-groups-creating-a-custom-split-list
https://forum.jquery.com/topic/css-code-to-help-control-entire-button-in-a-jquery-mobile-theme
Hope that helps.

Scriptaculous: How to make blind or slide smooth and not jump? Or is it not possible?

I was seeing a strange phenomena when using Scriptaculous BlindDown and SlideDown effects, where they would smoothly slide, and then at the very end, they would jump an additional amount, maybe 10% of the slide distance.
I already saw the note on the BlindDown page that you have to be sure not to use padding, which I'd already done.
I was still thinking that this must be my mistake somehow, when I noticed that I see the exact same thing happening on their demo page for Toggle when clicking on either the Blind or Slide demos:
http://wiki.github.com/madrobby/scriptaculous/effect-toggle
Firefox 3.6.7, Chrome 6, and Internet Explorer 8 all display this effect on my computer.
So I was thinking about just writing it off and either living with it or cutting the effect out, when I noticed that the page for BlindDown does not display this effect:
http://wiki.github.com/madrobby/scriptaculous/effect-blinddown
So there must be a way to make this work. On my page, the jump is occurring whether I directly use BlindDown/Slide or whether I use Toggle.
Has anyone out there used these and managed to do so without this problem? Any ideas on what the secret is?
It's usually due to margin or padding.
The element you're blind-downing mustn't have any margin or padding, or should have margin:0.1% so that contained margins don't collapse through the bounds of the element either. If you do this it'll be smooth as silk.
also - ensure you've set overflow:hidden
Enjoy.
(the other place it'll fall down is if you don't define height. If you do this little incantation before you animate it'll get and set you height without bothering anything else.
elem.setStyle({position:'absolute',visiblity:'invisible'});
elem.setStyle({'height':elem.getDimensions().height+'px'});
elem.setStyle({position:'relative',visibility:'visible'}); //or position:'static'
In my experience, the jumping is just a performance issue, which is effected by the system specs, browser, and complexity of the html content you are toggling. Some browsers like safari and chrome have a pretty good javascript engine making them more efficient.
I see this is happening for you even when using chrome though? Is the html content particularly complex, or your computer overloaded with applications running?
There is definitely a little very well known secret... Have you tried wrapping your content in an extra div container? You should consider this best practice and almost a requirement specifically when using Scriptaculous effects.
For example... Say you want to slideDown or Toggle a login form - and you have::
<div id="login-panel">
<input type="text" name="username" />
<button type="submit" name="send">Login</button>
</div>
All you have to do is add an extra inner div tag::
<div id="login-panel">
<div><!-- extra div here -->
<input type="text" name="username" />
<button type="submit" name="send">Login</button>
</div><!-- close it here -->
</div>
Now when you do something like Effect.toggle("login-panel", 'slide'); the transition should be much smoother and less jumpy. It may seem a little sloppy but it almost always helps. Hope this helps you!!
Keep in mind that when Scriptaculous begins an animation, the container that is being modified will be absolutely positioned and then a record of the height will be taken, similar to what danielsherson mentions. If however the container does not exist within a relatively positioned parent container, then the dimensions of the animating container may change quite drastically. The easiest way to test this is to modify your container using firebug to set the position to absolute. What happens? Did the height change? For the best results, there should be no change in the dimensions of your animating container when switching to absolute positioning. What happens to the rest of your document, such as content moving underneath, will not matter.
The padding/margin issue is a tricky one too since there really isn't a way to prevent the margins from overlapping and creating issues. Best way I found to address this is to set your animating container to float and then use the clearfix hack on a parent container to make sure nothing overlaps.
<body style="margin: 0 auto; width: 300px; position: relative; background: black;">
<div class="parent nonanimating clearfix">
<div class="animating" style="float: left; width: 100%; background: white;">
<div class="apply-your-margins-and-padding-here">
...content...
</div>
</div>
</div>
<div class="parent nonanimating clearfix">
<div class="animating" style="float: left; width: 100%; background: white;">
<div class="apply-your-margins-and-padding-here">
...content...
</div>
</div>
</div>
</body>
Note that the classes are not functional and just for reference to my comments with the exception of clearfix, which is the float clear hack. The backgrounds and widths are only specified to give a better example of what is happening. Add whatever animation you'd like to $$('.animating')
I use this one (there are many), all though it is old and I don't even design for many of the browsers this hack supports..
.clearfix:after {
content: ".";
display: block;
clear: both;
visibility: hidden;
height: 0;
}
.clearfix {
display: inline-block;
}
/* Hides from IE-mac \*/
* html .clearfix {height: 1%;}
.clearfix {display: block;}
/* End hide from IE-mac */
I don't think it's a performance issue at all. I'm having the same issue. The ONLY way I've been able to make it not jump is to define a height for the div I'm sliding. I realize that this is NOT a good solution but it's the only one I've been able to find. I've also tried adding the additional div and it had no effect on how the Effect.toggle slide worked.
If anyone else has any more info on this, I'm all ears.
To prevent a Scriptaculous effect from jumping or jerking, remove the 'style' attribute from the element which you are applying the Effect to.
This:
<div id="mydiv" style="padding:10px;margin:10px;">
<button onClick="new Effect.BlindUp('mydiv');" />
</div>
Becomes:
<div id="mydiv">
<button onClick="new Effect.BlindUp('mydiv');" />
</div>
The styling can be placed in a enclosed div like this:
<div id="mydiv">
<div style="padding:10px;margin:10px;">
<button onClick="new Effect.BlindUp('mydiv');" />
</div>
</div>
The problem is caused by Scriptaculous reapplying the element's (mydiv) inline style declarations after the effect has been performed.
I have found success with using position: relative; on the block element using the slide/blind animation. Make sure padding/margins are placed on the child elements and not the slide block element.
