Get ASP.NET WebForms ComboBox element when JQuery autocompleteselect is fired - javascript

How can I get the underlying select element when JQuery autocompleteselect is fired? I need that element to fire its onchange(). The underlying select element is an ASP.NET DropDown control. Here's the code:
this._on(this.input, {
autocompleteselect: function (event, ui) {
var ele = this; //<---not working
ui.item.option.selected = true;
this._trigger("select", event, {
item: ui.item.option
});
},
autocompletechange: "_removeIfInvalid"
});

Finally I figured it out:
autocompleteselect: function (event, ui) {
ui.item.option.selected = true;
this._trigger("select", event, {
item: ui.item.option
});
var underlyingEle = document.getElementById(
ui.item.option.parentElement.id // <-- fetching the underlying select element
);
underlyingEle.onchange();
}
Hope this helps someone in future. :)

Jquery Ui AutoComplete is not working with keyup/down when used with label value

When using keyup keydown to select option from autocomplete list textbox is showing value. But incase of selection from mouse it is working properly.
JsFiddle - http://jsfiddle.net/0c21r1pe/1
$("#promoteActionTextBox").autocomplete({
source: actionNames,
minLength: 0,
select: function (event, ui) {
event.preventDefault();
$(this).val(ui.item.label);
$('#promoteActionError').hide();
$(this).attr('actionId', ui.item.value);
},
change: function (event, ui) {
if (!ui.item) {
$(this).val('');
}
else {
$('#promoteActionError').hide();
$(this).val(ui.item.label);
$(this).attr('actionId', ui.item.value);
}
}
}).focus(function (event, ui) {
event.preventDefault();
$('#promoteActionTextBox').autocomplete("search");
this.value = ui.item.label;
});
change the object property name from value to something else and it works
WORKING DEMO
UPDATE
How about THIS FIDDLE
I added a code which removes the event which is responsible for that effect.
create:function(){
$('.ui-autocomplete').unbind('menufocus');
}
select: function(event, ui) {
event.preventDefault(); // Add on keyboard keyup, keydown is working well
$("#id_value").val(ui.item.value);
$("#id_label").val(ui.item.label);
},
focus: function( event, ui ) {
event.preventDefault(); // Add on keyboard keyup, keydown is working well
$("#id_value").val(ui.item.value);
$("#id_label").val(ui.item.label);
}

update the unselectable value (jquery)

i'm using selectable jquery, i want to cater the value for selectable once the use select or unselect the item. My problem is, the last value of unselectable won't update.
Full code here http://jsfiddle.net/duQH6/ When I select Mon and Tue, then I unselect the Tue, the value is updated, but then when I click Mon, the value is not updated. Please advice.
Here my jquery code
$(function() {
$("#selectday1").bind('mousedown', function (e) {
e.metaKey = true;
}).selectable();
});
$('document').ready(function(){
$( "#selectday1" ).selectable({
selected: function(event, ui) {
var result=[];
jQuery(".ui-selected", this).each(function()
{
result.push(this.id);
$("#days").val(result.join(','))
});
}
});
$( "#selectday1" ).selectable({
unselected: function(event, ui) {
var result=[];
jQuery(".ui-selected", this).each(function()
{
result.push(this.id);
$("#days").val(result.join(','))
});
}
});
});
Thanks..
The problem is, you are updating the days value within the each loop, so when you unselect the last element the loop callback is never executed, that is why it is happening.
The days value is supposed to be updated once the each() loop is completed.
$(document).ready(function () {
$("#selectday1").selectable({
selected: function (event, ui) {
var result = [];
jQuery(".ui-selected", this).each(function () {
result.push(this.id);
});
$("#days").val(result.join(','))
},
unselected: function (event, ui) {
var result = [];
jQuery(".ui-selected", this).each(function () {
result.push(this.id);
});
$("#days").val(result.join(','))
}
});
});
Demo: Fiddle
But it can be simplified to
jQuery(function ($) {
function serialize(event, ui) {
var result = $(this).find(".ui-selected").map(function () {
return this.id;
}).get();
$("#days").val(result.join(','))
}
$("#selectday1").selectable({
selected: serialize,
unselected: serialize
});
});
Demo: Fiddle

Jquery Autocomplete key press down display label name rather than value?

Is there a way you can force jQueryUI autocomplete to display data label rather than data value:
For example
[{"label":"name","value":"1"},{"label":"name3","value":"6"},{"label":"name1","value":"8"},{"label":"name2","value":"10"}]
$( ".auto-search" ).autocomplete({
minLength: 2,
dataType: 'json',
source: tempJson,
focus: function(event, ui){
$('input[name="user-name"]').val(ui.item.label);
},
select: function (event,ui){
$('input[name="user-name"]').val(ui.item.label);
$('input[name="user-id"]').val(ui.item.value);
return false;
}
})
The above code, when you press the down button, displays the value rather than the label. Can it be changed to show the label?
Make sure to return false or prevent the default action of the event from your focus event handler:
focus: function(event, ui){
event.preventDefault();
$('input[name="user-name"]').val(ui.item.label);
},
The callback function is not working on me. so i used a bind event autocompletefocus and worked just fine.
$('input[name="user-name"]').on("autocompletefocus", function (event, ui) {
event.preventDefault();
$(this).val(ui.item.label);
});

Jquery UI Tabs Enable/Disable events not firing

I am trying to toggle a series of navigation buttons to react when I disable/enable tabs. However the tabs enable and disable methods don't seem to be firing them (or perhaps the binding is wrong).
This works:
$('body').on('tabsload', '.tabContainer', function (event, ui) {
$(ui.panel).find(".tab-loading").remove();
});
This does not work:
$('body').on('tabsenable', '.tabContainer', function (event, ui) {
debugger;
});
$('body').on('tabsdisable', '.tabContainer', function (event, ui) {
debugger;
});
I am enabling the tabs this way:
$tabContainer.tabs('option', 'disabled', []);
Does this not fire an event? Thanks.
I think the error is set the option disabled and not call a method.
Try this:
$(".tabContainer").tabs('enable');
$(".tabContainer").tabs('disable');
And:
$(".tabContainer").bind("tabsenable", function(event, ui){
// action...
});
$(".tabContainer").bind("tabsdisable", function(event, ui){
// action...
});

Preventing click event with jQuery drag and drop

I have elements on the page which are draggable with jQuery. Do these elements have click event which navigates to another page (ordinary links for example).
What is the best way to prevent click from firing on dropping such element while allowing clicking it is not dragged and drop state?
I have this problem with sortable elements but think it is good to have a solution for general drag and drop.
I've solved the problem for myself. After that I found that same solution exists for Scriptaculous, but maybe someone has a better way to achieve that.
A solution that worked well for me and that doesn't require a timeout: (yes I'm a bit pedantic ;-)
I add a marker class to the element when dragging starts, e.g. 'noclick'. When the element is dropped, the click event is triggered -- more precisely if dragging ends, actually it doesn't have to be dropped onto a valid target. In the click handler, I remove the marker class if present, otherwise the click is handled normally.
$('your selector').draggable({
start: function(event, ui) {
$(this).addClass('noclick');
}
});
$('your selector').click(function(event) {
if ($(this).hasClass('noclick')) {
$(this).removeClass('noclick');
}
else {
// actual click event code
}
});
Solution is to add click handler that will prevent click to propagate on start of drag. And then remove that handler after drop is performed. The last action should be delayed a bit for click prevention to work.
Solution for sortable:
...
.sortable({
...
start: function(event, ui) {
ui.item.bind("click.prevent",
function(event) { event.preventDefault(); });
},
stop: function(event, ui) {
setTimeout(function(){ui.item.unbind("click.prevent");}, 300);
}
...
})
Solution for draggable:
...
.draggable({
...
start: function(event, ui) {
ui.helper.bind("click.prevent",
function(event) { event.preventDefault(); });
},
stop: function(event, ui) {
setTimeout(function(){ui.helper.unbind("click.prevent");}, 300);
}
...
})
I had the same problem and tried multiple approaches and none worked for me.
Solution 1
$('.item').click(function(e)
{
if ( $(this).is('.ui-draggable-dragging') ) return false;
});
does nothing for me. The item is being clicked after the dragging is done.
Solution 2 (by Tom de Boer)
$('.item').draggable(
{
stop: function(event, ui)
{
$( event.originalEvent.target).one('click', function(e){ e.stopImmediatePropagation(); } );
}
});
This works just fine but fails in one case- when I was going fullscreen onclick:
var body = $('body')[0];
req = body.requestFullScreen || body.webkitRequestFullScreen || body.mozRequestFullScreen;
req.call(body);
Solution 3 (by Sasha Yanovets)
$('.item').draggable({
start: function(event, ui) {
ui.helper.bind("click.prevent",
function(event) { event.preventDefault(); });
},
stop: function(event, ui) {
setTimeout(function(){ui.helper.unbind("click.prevent");}, 300);
}
})
This does not work for me.
Solution 4- the only one that worked just fine
$('.item').draggable(
{
});
$('.item').click(function(e)
{
});
Yep, that's it- the correct order does the trick- first you need to bind draggable() then click() event. Even when I put fullscreen toggling code in click() event it still didn't go to fullscreen when dragging. Perfect for me!
I'd like to add to this that it seems preventing the click event only works if the click event is defined AFTER the draggable or sortable event. If the click is added first, it gets activated on drag.
I don't really like to use timers or preventing, so what I did is this:
var el, dragged
el = $( '#some_element' );
el.on( 'mousedown', onMouseDown );
el.on( 'mouseup', onMouseUp );
el.draggable( { start: onStartDrag } );
onMouseDown = function( ) {
dragged = false;
}
onMouseUp = function( ) {
if( !dragged ) {
console.log('no drag, normal click')
}
}
onStartDrag = function( ) {
dragged = true;
}
Rocksolid..
lex82's version but for .sortable()
start: function(event, ui){
ui.item.find('.ui-widget-header').addClass('noclick');
},
and you may only need:
start: function(event, ui){
ui.item.addClass('noclick');
},
and here's what I'm using for the toggle:
$("#datasign-widgets .ui-widget-header").click(function(){
if ($(this).hasClass('noclick')) {
$(this).removeClass('noclick');
}
else {
$(this).next().slideToggle();
$(this).find('.ui-icon').toggleClass("ui-icon-minusthick").toggleClass("ui-icon-plusthick");
}
});
A possible alternative for Sasha's answer without preventing default:
var tmp_handler;
.sortable({
start : function(event,ui){
tmp_handler = ui.item.data("events").click[0].handler;
ui.item.off();
},
stop : function(event,ui){
setTimeout(function(){ui.item.on("click", tmp_handler)}, 300);
},
In jQuery UI, elements being dragged are given the class "ui-draggable-dragging".
We can therefore use this class to determine whether to click or not, just delay the event.
You don't need to use the "start" or "stop" callback functions, simply do:
$('#foo').on('mouseup', function () {
if (! $(this).hasClass('ui-draggable-dragging')) {
// your click function
}
});
This is triggered from "mouseup", rather than "mousedown" or "click" - so there's a slight delay, might not be perfect - but it's easier than other solutions suggested here.
In my case it worked like this:
$('#draggable').draggable({
start: function(event, ui) {
$(event.toElement).one('click', function(e) { e.stopPropagation(); });
}
});
After reading through this and a few threads this was the solution I went with.
var dragging = false;
$("#sortable").mouseover(function() {
$(this).parent().sortable({
start: function(event, ui) {
dragging = true;
},
stop: function(event, ui) {
// Update Code here
}
})
});
$("#sortable").click(function(mouseEvent){
if (!dragging) {
alert($(this).attr("id"));
} else {
dragging = false;
}
});
the most easy and robust solution? just create transparent element over your draggable.
.click-passthrough {
position: absolute;
left: 0;
top: 0;
right: 0;
bottom: 0;
background: transparent;
}
element.draggable({
start: function () {
},
drag: function(event, ui) {
// important! if create the 'cover' in start, then you will not see click events at all
if (!element.find('.click-passthrough').length) {
element.append("<div class='click-passthrough'></div>");
}
},
stop: function() {
// remove the cover
element.find('.click-passthrough').remove();
}
});
Have you tried disabling the link using event.preventDefault(); in the start event and re-enabling it in the drag stopped event or drop event using unbind?
Just a little wrinkle to add to the answers given above. I had to make a div that contains a SalesForce element draggable, but the SalesForce element has an onclick action defined in the html through some VisualForce gobbledigook.
Obviously this violates the "define click action after the drag action" rule, so as a workaround I redefined the SalesForce element's action to be triggered "onDblClick", and used this code for the container div:
$(this).draggable({
zIndex: 999,
revert: true,
revertDuration: 0,
start: function(event, ui) {
$(this).addClass('noclick');
}
});
$(this).click(function(){
if( $(this).hasClass('noclick'))
{
$(this).removeClass('noclick');
}
else
{
$(this).children(":first").trigger('dblclick');
}
});
The parent's click event essentially hides the need to double-click the child element, leaving the user experience intact.
I tried like this:
var dragging = true;
$(this).click(function(){
if(!dragging){
do str...
}
});
$(this).draggable({
start: function(event, ui) {
dragging = true;
},
stop: function(event, ui) {
setTimeout(function(){dragging = false;}, 300);
}
});
for me helped passing the helper in options object as:
.sortable({
helper : 'clone',
start:function(),
stop:function(),
.....
});
Seems cloning dom element that is dragged prevented the bubbling of the event. I couldnĀ“t avoid it with any eventPropagation, bubbling, etc. This was the only working solution for me.
The onmousedown and onmouseup events worked in one of my smaller projects.
var mousePos = [0,0];
function startClick()
{
mousePos = [event.clientX,event.clientY];
}
function endClick()
{
if ( event.clientX != mousePos[0] && event.clientY != mousePos[1] )
{
alert( "DRAG CLICK" );
}
else
{
alert( "CLICK" );
}
}
<img src=".." onmousedown="startClick();" onmouseup="endClick();" />
Yes, I know. Not the cleanest way, but you get the idea.
