I am developing an app having UI which is used for mapping fields (Source => Destination).
These fields would appear in UL -> LI -> DIV
The lists are going to be created dynamically by PHP.
Source fields are draggable with revert:true, where as Destination fields (droppable) would accept source field. I know the accept : "#divsource"
I am able to make many div's draggable, but my problem is how to define many LI->Div as droppable.
At then end the drop event would call ajax and that I can handle as well.
I am new to jQuery and whatever I have learned till now is with this task is all I know. But, my quick learning ability is not a problem.
Please help with some example.
thanks

Below code is something I have been playing with. I know it's bit far off from what eventually it should look like:
<script type="text/javascript">
$(document).ready(function(){
$('.srcfield').draggable({
revert: true,
helper: "clone"
});
$('#destinationfeilds').droppable({
accept : ".srcfield",
over: function(){
$(this).removeClass('out').addClass('over');
},
out: function(){
$(this).removeClass('over').addClass('out');
},
drop: function(ev, ui){
//var answer = confirm('Delete this item?');
var theTitle = $(ui.draggable).attr("title");
$(this).html("<u>"+theTitle+"</u><br/> is mapped!");
//$(this).removeClass('over').addClass('out');
//alert(theTitle);
}
});
});
</script>
</head>
<body>
<div id="destinationfeilds" class="out">
<span>Destination</span>
</div>
<div id="destinationfeilds" class="out">
<span>Destination</span>
</div>
<div id="sourcefields">
<div class="srcfield" title="First Name"><span>First Name</span></div>
<div class="srcfield" title="Last Name"><span>Last Name</span></div>
<div class="srcfield" title="Age"><span>Age</span></div>
</div>
</body>

`<%= f.radio_button :customer, "Female",:value=>'Customer'%>`
<div id="first"></div>
<div id="second"></div>
I am new in rails.I have two radiobuttons and two div.When i click NewCustomer i want to hide first div and when i click on the Customer show the hidden div.I want to do this in only Ruby code.Is there any radiobutton click event like in .net
You can achieve it by Javascript / JQuery / Ajax in rails:
Example:
HTML
<input type="radio" name='thing' value='valuable' data-id="female" />
<input type="radio" name='thing' value='valuable' data-id="male" />
<hr />
<div id="female" class="none">Div for Male</div>
<div id="male" class="none">Div for Female</div>
CSS:
.none {display:none;}
JQuery
$(':radio').change(function (event) {
var id = $(this).data('id');
$('#' + id).addClass('none').siblings().removeClass('none');
});
Working Fiddle
Pipeline
To further Gagan's answer, you'll want to include your Javascript in the asset_pipeline:
#app/assets/javascripts/application.js
$(document).on("change", ".radio", function(){
// gagan's code here
});

Turbolinks
Something to note is the importance of the javascript "delegation" - when you use Rails applications with Turbolinks.
Because of the way in which Turbolinks will just update the <body> tag of your page, many JS event bindings will actually become invalid, preventing your application from loading correctly.
To fix this, you need to be able to either delegate your DOM events from a "container" element (typically document), or by encapsulating your code in Turbolinks events like so:
#app/assets/javascripts/application.js
var change = function() {
$(".radio").on("change", function(){
//Stuff here
});
};
$(document).on("page:load ready", change);
I have something like this:
$('#mover' ).draggable({});
$('div').droppable({
drop: function(event, ui) {
console.log(event.target.id)
}
then
<div id="container">
<div id="target_1"></div>
<div id="target_2"></div>
<div id="target_3"></div>
</div>
When I drop mover on a div "container" is returned. how do I return instead the lowest child that the item was dropped on?
I know the solution to the actual problem: I was trying to drop an element on same div that it came from.
I'm using backbone jquery mobile and coffee script to develop a simple twitter application. My problem is the jquery mobile styles are failing to render. My View is
class HomeView extends Backbone.View
constructor: ->
super
initialize: ->
#Twitter= new TwitterCollection
template: _.template($('#home').html())
render: ->
#loadResults()
loadResults: ->
#Twitter.fetch({
success: (data) =>
$(#.el).html(#template({data: data.models, _:_}))
error: ->
alert('Error!')
})
This works fine in terms of pulling information from Twitter, however when
$(#.el).html(#template({data: data.models, _:_}))
is within the fetch function, jquerys styles do not render. Can anyone show me how to refresh the styles? Help would be much appreciated!
For reference, the html template is:
<script type="text/template" id="home">
<div data-role="header" data-position="fixed">
<h1>TWITTER DATA</h1>
</div>
<div data-role="content">
<ul data-role="listview" data-inset="true">
<% _.each(data, function (row) { %>
<li><%= row.get('text') %></li>
<% }); %>
</ul>
</ul>
</div>
Ok, I fixed it by adding ".listview('refresh').trigger('create');" to the end of
$(#.el).html(#template({data: data.models, _:_}))
When the fix is applied afterwards (after the view page has been rendered and displayed by $.mobile.changePage()) the user gets an unpleasant side-effect: the view flickers due to the change of style applied by jquery mobile.
My solution to the problem was to trigger custom event from the view once the dynamic rendering is complete and bind the $.mobile.changePage() to that event. This causes the output to be "buffered" until complete and then styled altogether.
Here's an example:
In the initialize function of my view I have code waiting for an event to be fired by the model/collection when fetched and a function to render the dynamic part of the html:
window.MyView = Backbone.View.extend({
// some other code here
initialize: function() {
this.listenTo(this.collection, "fetchCompleted:CollectionName", this.renderRows);
},
renderRows: function (eventName) {
$(this.el).find('div[class="content-primary"]').html(this.template_ul({data: this.collection}));
this.trigger( 'view:ready' );
},
//...
... then in the router I have the following code for the changePage():
myViewObject.on( 'view:ready', function() {
$.mobile.changePage($(next.el), {changeHash:false, transition: transition});
});
I know this has been discussed before, but with no results for me.
The problem is that deviceready() is only fired once, the first time on "list" page. I can´t get it to work on article pages. And when I go back from a "article" page to "articlelist" the event is still out of work. I need the menubutton operative in every data-role="page".
The js:
<script type='text/javascript'>
function onLoad() {
document.addEventListener("deviceready", onDeviceReady, false);
}
function onDeviceReady() {
document.addEventListener("menubutton", onMenuKeyDown, false);
}
function onMenuKeyDown() {
alert('Menu pressed');
}
</script>
The HTML:
<body onload="onLoad()">
<div id="list" data-role="page">
<ul id="articleList" data-role="listview">
<li id="list1"><a id="link1" href="#article1"></li>
<li id="list2"><a id="link1" href="#article2"></li>
</ul>
</div>
<div id="article1" data-role="page">Content</div>
<div id="article2" data-role="page">Content</div>
I'm with: cordova-1.5.0 /jquery.mobile-1.1.0-rc.2 /jquery-1.7.1 /Android
Any help please?
I just quickly tested this in the app I'm working on right now and it works. Phonegap-1.6.1 and jquery.mobile-1.1.0 final
Perhaps you should try upgrading your phonegap and jquery.mobile
I am trying to do the following:
The object I give to the Viewpage has a list, I do a foreach in the HTML and I create a number of components. Now, I want the IDs of those components to somehow be linked to the object from the List.
(The reason I am trying to do this is because I want to show a button, when they press that button the shown content will change and they should see something else, I will use javascript to achieve this)
Therefor I am trying to make the id of those components dynamic, by for example stating
id="button <%= item.id%>" however this does not seem to work. I have searched alot on google but I haven't found a solution yet which is why I turn to you guys.
I'll link my code as well, I deleted some of the parts that were unnecessary (but added the javascript):
<script type="text/javascript">
function AlterPanel(thePanel) {
var panel = document.getElementById("region"+thePanel);
panel.style.display = 'block';
var button = document.getElementById("button"+thePanel);
button.style.display = 'none';}
</script>
<%foreach (TeamDTO team in Model.List.Teams)
{ %>
<a id="button<%= team.Number %>" onclick="AlterPanel(<% team.Number%>)">
Add member</a>
<div Visible="false" id='region<%= team.Number %>' runat="server">
Please select one:
<%: Html.DropDownListFor(V => V.memberID, new SelectList(Model.members, "ID","Name")) %>
</div>
<% } %>
I eagerly await a reply and thank you in advance.
I guess your Queastion is:
-you have some "button DropDownList" pair, button is visiable, DropDownList is invisible, now if user click the button then DropDownList will showup.
OK, now your View maybe :
<%foreach (TeamDTO team in Model.List.Teams)
{ %>
<a onclick="AlterPanel(<% team.Number%>)">
Add member</a>
<div id="region<%= team.Number %>" style="display:none">
Please select one:
<%: Html.DropDownListFor(V => V.memberID, new SelectList(Model.members, "ID","Name")) %>
</div>
<% } %>
I use JQuery in javascript part like this:
<script type="text/javascript">
function AlterPanel(thePanel) {
$("#region" + thePanel.toString()).css("display", "block");
}
</script>
Don't forget include the following file in View():
<script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery-1.4.1.min.js") %>"></script>
if the answer is not what you want, let mt know and I can help you~ :)
