Sortable receive event dynamic - jquery-ui

I'm using jQuery UI Sortable to make a menu builder and i have a little problem when i try to execute the :receive Event with dynamic contents. (Receive Event are not executed when try to add something on dynamic content).
$(document).ready(function(){
$( ".parentmenu, .submenu" ).sortable({
connectWith: ".connected",
receive: function( event, ui ) {
var $item = $(ui.item);
$item.addClass('dropdown');
$item.find('a:first').addClass('dropdown-toggle');
$item.find('a:first').attr('data-toggle', 'dropdown');
$item.find('a:first').attr('aria-expanded', 'false');
var x = '<ol class="dropdown-menu dropdown-menu-left connected submenu ui-sortable"><div class="menu-builder-tools"><i class="icon-info3"></i> Drag and Drop an element here</div></ol>';
$(x).appendTo($item).sortable({connectWith: 'connected'});
alert('received');
}
});
});
Can anybody give me a hand please ?
MY JSfiddle
Thank You!

I found the answer:
Replace: $(x).appendTo($item).sortable({connectWith: 'connected'});
With: $(x).appendTo($item).sortable({connectWith: 'connected', receive: function( event, ui ) {alert('test');}});

Fail to refresh jquery mobile listview after item added by ngClick

I am trying to add item into listview of jquery mobile dynamically. I add item using a ngClick event and show list using ngRepeat. I have called listview refresh but the latest item cannot style properly. Which event should I use to refresh properly? Thanks.
$scope.addItem = function () {
$scope.userList.push($scope.userInputText);
$scope.userInputText = null;
$("#listview1").listview("refresh");
}
http://jsfiddle.net/hFj2T/
The following directive works for me. Just add list-view to your ul tag and also the data-watch="userList" to tell angular which object to watch for changes.
<ul list-view data-watch="userList" data-role="listview" data-filter="true" >
<li ng-repeat="user in userList">{{user.name}}</li>
</ul>
app.directive('listView', function () {
var link=function(scope, element, attrs) {
$(element).listview();
scope.$watchCollection(attrs.watch, function() {
$(element).listview("refresh");
});
};
return {
restrict: 'EA',
scope:false,
link: link
};
});
Give a timeout for styling the list view:
$scope.addItem = function () {
$scope.userList.push($scope.userInputText);
$scope.userInputText = null;
setTimeout(function(){
$("#listview1").listview("refresh");
},100);
}
This is happening because both JQuery UI and Angular are attempting to update the DOM using the document ready event. A race condition is occurring in which Angular is adding the new data after JQuery has already created the listview. Sheetal's solution works because it forces JQuery to modify the DOM and create the listview after Angular has populated the data.
Another solution is a tool aptly called the jquery mobile angular adapter

Keep jQuery tooltip open on click?

I want to use jQuery UI's tooltip feature, however I need it so when you click an element (in my case an image) the tool tip stays open. Can this be done? I couldn't see any options for this.
http://api.jqueryui.com/tooltip/
UPDATE here is my code. I thought the 4th line should work but sadly not:
HTML
<img class="jqToolTip" src="/query.gif" title="Text for tool tip here">
Javascript
$('.jqToolTip').tooltip({
disabled: false
}).click(function(){
$(this).tooltip( "open" );
// alert('click');
}).hover(function(){
// alert('mouse in');
}, function(){
// alert('mouse out');
});
I was trying to solve the same exact problem, and I couldn't find the answer anywhere. I finally came up with a solution that works after 4+ hours of searching and experimenting.
What I did was this:
Stopped propagation right away if the state was clicked
Added a click handler to track the state
//This is a naive solution that only handles one tooltip at a time
//You should really move clicked as a data attribute of the element in question
var clicked;
var tooltips = $('a[title]').on('mouseleave focusout mouseover focusin', function(event) {
if (clicked) {
event.stopImmediatePropagation();
}
}).tooltip().click(function() {
var $this = $(this);
var isOpen = $this.data('tooltip');
var method = isOpen ? 'close' : 'open';
$this.tooltip(method);
//verbosity for clarity sake, yes you could just use !isOpen or clicked = (method === 'open')
if (method === 'open') {
clicked = true;
} else {
clicked = false;
}
$this.data('tooltip', !isOpen);
});

jquery mobile: how to create dynamic content only once, at page startup?

Here's what I want to do:
load basket using Ajax
show "wait" message
once loaded, refresh basket.
When I try to use pageinit function:
$(document).bind('pageinit', function(evt) {
console.log(evt);
}
Console log show it's called 29 times!
Everything is on one HTML page, and I'm using $.mobile.changePage() to change pages. So I tried this hack:
$(document).bind('pagebeforeshow', function(evt, pg) {
if (pg.prevPage.length==0) {
/* first page = code executed once */
var pg = $('#page-basket'),
footer = pg.children( ":jqmData(role=footer)" );
footer.hide().trigger('updatelayout');
AjaxGetBasket( function(data) { console.log('ajax basket ok'); });
}
});
But the layout is never updated.
How shall I do to modify page but only once at the beginning?
Try delegating the pageinit event handler so it only runs when #page-basket is initialized:
$(document).on("pageinit", "#page-basket", function() {
$(this).children(":jqmData(role=footer)").hide().trigger("updatelayout");
AjaxGetBasket(function(data) {
console.log("ajax basket ok");
});
});
I do not understand if your problem is solved, but i am in the same situation explained in the question and i have solved the problem binding a function to pagecreate event:
$(document).bind("pagecreate", function(e){
// call ajax and update the DOM of first 'page'
});
and that's all.

jQuery UI autocomplete select event not working with mouse click

I have a list of links, and I have this search box #reportname. When the user types in the search box, autocomplete will show the text of the links in a list.
<div class="inline">
<div class="span-10">
<label for="reportname">Report Name</label>
<input type="text" name="reportname" id="reportname" />
</div>
<div class="span-10 last">
<button type="button" id="reportfind">Select</button>
</div>
</div>
The user can then use the keyboard arrow to select one of the text, and when he press ENTER, browser will go to the address of the link. So far so good.
<script type="text/javascript">
$(document).ready(function () {
$("#reportname").autocomplete({
source: $.map($("a.large"), function (a) { return a.text }),
select: function () { $("#reportfind").click() }
})
$("#reportfind").click(function () {
var reportname = $("#reportname")[0].value
var thelinks = $('a.large:contains("' + reportname + '")').filter(
function (i) { return (this.text === reportname) })
window.location = thelinks[0].href
})
});
</script>
The issue is when the user types, autocomplete shows a list, and then the user use the mouse to click one of the result. With keyboard navigation, the content of the search box is changed, but if the user clicks one of the options, the search box is not modified and the select event is immediately triggered.
How can I make the script work with keyboard selection and mouse selection? How can I differentiate between select events that are triggered by keyboard with the ones triggered by mouse?
To your 2nd question: "How can I differentiate between select events that are triggered by keyboard with the ones triggered by mouse?"
The event object in the jQuery UI events would include a .originalEvent, the original event it wrapped. It could have been wrapped multiple times though, such as in the case of Autocomplete widget. So, you need to trace up the tree to get the original event object, then you can check for the event type:
$("#reportname").autocomplete({
select: function(event, ui) {
var origEvent = event;
while (origEvent.originalEvent !== undefined)
origEvent = origEvent.originalEvent;
if (origEvent.type == 'keydown')
$("#reportfind").click();
},
...
});
Thanks to #William Niu and firebug, I found that the select event parameter 'ui' contains the complete selected value: ui.item.value. So instead of depending on jquery UI to change the text of the textbox, which didn't happen if the user clicks with mouse, I just pick up the selected value from 'ui':
$("#reportname").autocomplete({
select: function (event, ui) {
var reportname = ui.item.value
var thelinks = $('a.large:contains("' + reportname + '")').filter(
function (i) { return (this.text === reportname) })
window.location = thelinks[0].href
};
})
I tested it in all version of IE (inlcuding 9) and always ended up with an empty input-control after I selected the item using the mouse. This caused some headaches. I even went down to the source code of jQuery UI to see what happens there but didn’t find any hints either.
We can do this by setting a timeout, which internally queues an event in the javascript-engine of IE. Because it is guaranteed, that this timeout-event will be queued after the focus event (this has already been triggered before by IE itself).
select: function (event, ui) {
var label = ui.item.label;
var value = ui.item.value;
$this = $(this);
setTimeout(function () {
$('#txtBoxRole').val(value);
}, 1);
},
Had the same issue / problem.
Jquery: 1.11.1
UI: 1.11.0
Question: Do you use bassistance jquery validte plugin simultanously?
If positive: update this to a newest version or just disable it for tests.
I updated from 1.5.5 to 1.13.0
Helped for me. Good luck!
I recently encountered the exact same problem (autocomplete items not clickable, keyboard events working).
Turned out that in my case the answer was not at all JS related. The autocomplete UI was not clickable simply because it was lacking an appropriate value for the z-index CSS property.
.ui-autocomplete {
z-index: 99999; /* adjust this value */
}
That did the trick.
This may be a bit farshot, but I had a similar situation where selecting an autocomplete value left the input field empty. The answer was to ignore the "change" events (as those were handled by default) and replace them with binds to "autocompletechange" events.
The "change" event gets triggered before the value from autocomplete is in the field => the field had "empty" value when handling the normal "change" event.
// ignore the "change" event for the field
var item = $("#"+id); // JQuery for getting the element
item.bind("autocompletechange", function(event, ui) { [call your handler function here] }
I was facing a similar problem. I wanted to submit the form when the user clicked on an option. But the form got submitted even before the value of the input could be set. Hence on the server side the controller got a null value.
I solved it using a modified version of William Niu's answer.
Check this post - https://stackoverflow.com/a/19781850/1565521
I had the same issue, mouse click was not selecting the item which was clicked.My code was supposed to make an ajax call to fetch the data as per the selection item from autocomplete source.
Previous code: mouse click not working.
select: function(event, ui) {
event.preventDefault();
for(i= 0; i< customer.length; i++)
if(document.getElementById('inputBox').value == customer[i].name)
{
$.ajax({
call
})
Changed code :mouse click working
select: function(event, ui) {
// event.preventDefault();
for(i= 0; i< customer.length; i++)
// if(document.getElementById('inputBox').value == customer[i].fields.name)
if(ui.item.value == customer[i].name)
{
$.ajax({
call
})
After inspecting the code in the developer tools console, I noticed there were two list items added. I removed the pairing <li></li> from my response code and oh yeah, the links worked
I also added this function as the click event:
$("#main-search").result(function ()
{
$("#main-search").val("redirecting...."), window.location.href = $("#main-search").attr("href").match(/page=([0-9]+)/)[1];
})
This works and you can test it here: Search for the term dress -->

jqueryUI Sortable: handling .disableSelection() on form inputs

example: i have an un-ordered list containing a bunch of form inputs.
after making the ul .sortable(), I call .disableSelection() on the sortable (ul) to prevent text-selection when dragging an li item.
..all fine but I need to re/enable text-selection on the form inputs.. or the form is basically un-editable ..
i found a partial solution # http://forum.jquery.com/topic/jquery-ui-sortable-disableselection-firefox-issue-with-inputs
enableSelection, disableSelection seem still to be un-documented: http://wiki.jqueryui.com/Core
any thoughts?
solved . bit of hack but works! .. any comments how i can do this better?
apply .sortable() and then enable text-selection on input fields :
$("#list").sortable({
stop: function () {
// enable text select on inputs
$("#list").find("input")
.bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
}
}).disableSelection();
// enable text select on inputs
$("#list").find("input")
.bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
A little improvement from post of Zack - jQuery Plugin
$.fn.extend({
preventDisableSelection: function(){
return this.each(function(i) {
$(this).bind('mousedown.ui-disableSelection selectstart.ui-disableSelection', function(e) {
e.stopImmediatePropagation();
});
});
}
});
And full solution is:
$("#list").sortable({
stop: function () {
// enable text select on inputs
$("#list").find("input").preventDisableSelection();
}
}).disableSelection();
// enable text select on inputs
$("#list").find("input").preventDisableSelection();
jQuery UI 1.9
$("#list").sortable();
$("#list selector").bind('click.sortable mousedown.sortable',function(e){
e.stopImmediatePropagation();
});
selector = input, table, li....
I had the same problem. Solution is quite simple:
$("#list").sortable().disableSelection();
$("#list").find("input").enableSelect();
The following will disable selection for the entire document, but input and select elements will still be functional...
function disableSelection(o) {
var $o = $(o);
if ($o.find('input,select').length) {
$o.children(':not(input,select)').each(function(x,e) {disableSelection(e);});
} else {
$o.disableSelection();
}
}
disableSelection(document);
But note that .disableSelection has been deprecated by jquery-ui and will someday go away.
EASY! just do:
$( "#sortable_container_id input").click(function() { $(this).focus(); });
and replace "sortable_container_id" with the id of the element that is the container of all "sortable" elements.
Quite old, but here is another way:
$('#my-sortable-component').sortable({
// ...
// Add all non draggable parts by class name or id, like search input texts and google maps for example
cancel: '#my-input-text, div.map',
//...
}).disableSelection();
