sortable - restrict dragging only to parent <li> element? - jquery-ui

I am using the sortable demo in jquery-ui. I am trying to add an item to the sortable list at runtime, like:
<ul id='panelSortable'>
</ul>
$("#panelSortable").sortable({
distance: '15'
});
function generatePanel() {
var html = "<li>";
html += "<p>hello!</p>";
html += "</li>";
return html;
}
function addPanel() {
var element = $(generatePanel());
element.appendTo("#panelSortable");
element.sortable();
element.disableSelection();
}
the new element gets added to the sortable list ok. I can strangely drag the "p" element though, separately from the parent "li" element (which is also draggable). I want to restrict dragging to just the "li" element.
If I just declare a few "li" items in the page, they all work the normal way, where you can only drag the "li" items, not their "p" child:
<ul id='panelSortable'>
<li><p>I work normally!</p></li>
</ul>
so I must be messing up the calls here to make the "p" elements also draggable?
Thanks

Argh ok you don't need to call sortable() on element, that should just be done on the parent "ul" item it looks like. If you remove that and just add the element as shown above, sorting is enabled on it just fine.
Thanks

split listview secondary button click event on dynamically added rows

I'm adding rows to a split listview with jQm, and I can only get the first row (not dynamically added) to trigger a click event. I assume there's a refresh function somewhere that I need to call, but I can't figure out what - I'm already refreshing the listview, which I expected to solve it...
Here's the fiddle:
http://jsfiddle.net/z36fy/1/
and here's the code:
<ul data-role="listview" data-split-icon="minus" id="list">
<li>
Item Description
remove
</li>
</ul>
Add item
JS:
var itemcount=1;
$('#addbtn').click(function() {
var addstr = '<li>Item Description '+itemcount+'remove</li></ul>';
$('#list').append(addstr);
$('#list').listview();
$('#list').listview('refresh');
itemcount++;
});
$('#list a.ui-li-link-alt').on("click",function() {
alert('delbtn clicked');
});
What am I missing?
Because you are dynamically adding DOM elements, you can't bind ahead of time. Instead use event delegation (https://learn.jquery.com/events/event-delegation/):
$('#list').on("click", ".delbtn", function() {
alert('delbtn clicked');
});
This says bind the click event to any items with class delbtn within the list even if they don't exist yet.

Autocomplete in JQUERY MOBILE text input

I searched a lot on net but couldnt find any solution. I am making a webapp in which I want 2 textbox to get data input from user. I want autocomplete feature in this textbox. The list of tags for autocomplete is available locally. I tried listview but what I want is that after user select some option from autocomplete hints, the textbox should have the selected value, and through some object, i should get the value of textbox to be used by javascript/php. This is a very basic thing, but I'm not able to do. Please help me out
I tried this jsfiddle.net/ULXbb/48/ . But the problem in this is that both listview gets same value after I select something in 1 listview.
In order not to add the same value to both search input, you need to target them using .closest(), .next(), .prev() and .find(). jQuery-Mobile, enhances list-view with data filter in a different way.
Demo
<form>
<input>
</form>
<ul data-role="listview">
<li>
<a>text</a>
</li>
</ul>
The form where the input is located, is on the same level of the ul. To target the input box, you need to use .prev('form').find('input'). Check the demo and the new code below.
$("input[data-type='search']").keyup(function () {
if ($(this).val() === '') {
$(this).closest('form').next("[data-role=listview]").children().addClass('ui-screen-hidden');
}
});
$('a.ui-input-clear').click(function () {
$(this).closest('input').val('');
$(this).closest('input').trigger('keyup');
});
$("li").click(function () {
var text = $(this).find('.ui-link-inherit').text();
$(this).closest('[data-role=listview]').prev('form').find('input').val(text);
$(this).closest('[data-role=listview]').children().addClass('ui-screen-hidden');
});
Thanks #user714852 I have extended your answer just add this line in the script tag:
$("#mylist li" ).addClass('ui-screen-hidden');
It will do wonders.

Grab all fieldset elements inside div

In my ASP MVC 3 view I have a number of fieldset elements that are hidden when the page loads. Based upon a user selection of a group of radio buttons, I need to make the corresponding fieldset visible.
I'd like to do this in jquery by making an array of the fieldset elements, then cycle through them, adjusting their visibility property if they match the selected radio button or not. Is this possible?
Since there is so much code in the fieldsets I attached the screen shot below to save space/make it more readable. The fieldsets I am trying to alter are inside of the RightDiv. If you need any more detail, please let me know. Thx
You can try this:
$(function(){
$('[name="TransactionType"]').change(function(){
var id = '#' + this.className; //Get the id from the clicked radio classname
$('#RightDiv').find('fieldset').hide();// hide all fieldsets;
$('#RightDiv').find(id).show(); // show the selected one.
});
});
Just note that in your html helper you are providing the the first overload as same name for all. All is well except i believe it will create duplicate ids for each of these. You may want to override it in the HTMLattributes.
#Html.RadioButton("TransactionType", false, new{#class="Enroll", id="Radio1"})
#Html.RadioButton("TransactionType", false, new{#class="New", id="Radio2"})
Sorry, posted a bit too soon on this. Tried the following below and it worked just fine.
$(document).ready(function () {
$('input[name=TransactionType]').change(function () {
var radioValue = $(this);
var elements = [];
$('#RightDiv').children().each(function () {
elements.push($(this));
});
});
});

Using sortable with Tag-it jqueryui

I've been using the tag-it plugin from https://github.com/aehlke/tag-it (demo - http://aehlke.github.com/tag-it/examples.html).
In this code there is an option to display the inputted tags in another input, textarea etc. First option -
$('#singleFieldTags').tagit({
availableTags: sampleTags,
singleField: true,
singleFieldNode: $('#mySingleField')
});
Here the id - #singleFieldTags is the inputting field which is a list like <ul and id - #mySingleField displays the 'list-ordered' tags with commas between each.
All the tags that are added and removed in the #singleFieldTags appear in the #mySingleField. Since there is no built-it sortable function with tag-it, adding a sortable() to change the order of tags in #singleFieldTags, does not change the order of tags in #mySingleField.
The second option is a plain with only #singleFieldTags as follows :-
$('#singleFieldTags').tagit({
availableTags: sampleTags,
});
Although in tag-it.js there is a , the value does not appear in the mysql table after submitting the php form as the above list of tags is placed between <li></li>.
How is it possible to make the tags sortable and ensure that the same arrangement of tags in the list field <ul to be displayed in the <textarea as in First Option? Or How can the second option of sorting tags within a single field <input work and enabling it to be submitted by a form?
EDIT: There is a similar plugin like Tag-it called tagit here: http://webspirited.com/tagit/ . This plugin has sortable with an input box meaning if the tags were interchanged, and when submitted on form it would appear in the order of the sort. However, the disadvantage being that it has custom themeroller themes these are not similar and cannot even be linked to the ones at jQuery UI (jqueryui.com).
But on the other hand, the tag-it plugin (not tagit), can be loaded with these themes but does not provide the sortable function.
Here's a solution that uses the tag-it plugin, because I understand that your missing functionality is explained in your quote "...adding a sortable() to change the order of tags in #singleFieldTags, does not change the order of tags in #mySingleField".
In order to have "#mySingleField" reflect the new sort order, I'm adding a handler to the stop event of sortable():
$('#singleFieldTags').sortable({
stop: function(event,ui) {
$('#mySingleField').val(
$(".tagit-label",$(this))
.clone()
.text(function(index,text){ return (index == 0) ? text : "," + text; })
.text()
);
}
});
and
$('#singleFieldTags2').siblings(".tagit").sortable({
stop: function(event,ui) {
$('#singleFieldTags2').val(
$(".tagit-label",$(this))
.clone()
.text(function(index,text){ return (index == 0) ? text : "," + text; })
.text()
);
console.log( $('#singleFieldTags2').val() ); // just for reference
}
});
Here is a jsfiddle that demonstrates the functionality
(added functionality for single input field)

Inserting element into DOM instead of appending using dart:html

The base Element object in dart:html has a property elements which is an implementation of List<E>. The add method appends elements to the DOM. I would like to prepend or insert an element into the DOM. None of the insert methods in ElementList are implemented. How can I do this?
So lets say you have this HTML snippet:
<body>
<div id='test'></div>
</body>
You can do this to insert an element before the div:
// Get the sibling that we want to insert before.
final el = query('#test');
// From the parent element, we call insertBefore, referencing the
// sibling that we want to insert the new element before.
document.body.insertBefore(new Element.tag('p'), el);
Now your HTML will be:
<body>
<p></p>
<div id='test'></div>
</body>
In addition to John's Answer. You can also use the syntax:
final el = query('#test');
// If you want an element
el.insertAdjacentElement('beforebegin', new Element.tag('p'));
// If you want to insert HTML tags
el.insertAdjacentHTML('beforebegin', '<p>Hello</p>');
// Insert just text
el.insertAdjacentText('beforebegin', 'Hello there');
You can use positional arguments: beforebegin, afterbegin, beforeend, afterend Which will place it before the beginning of the other element, just inside the beginning of the element, just inside the end of the element, or just outside the end of the element, respectively.
