I am using this snippet of code for my jQueryUI Autocomplete function on my site,
$( "#find" ).autocomplete({
minLength: 1,
source: function(request, response) {
var results = $.ui.autocomplete.filter(locations, request.term);
response(results.slice(0, 10));
},
focus: function( event, ui ) {
$( "#find" ).val( ui.item.value );
return false;
},
appendTo: "#results",
open: function(){
var position = $("#results").position(),
left = position.left, top = position.top;
$("#results > ul").css({left: (left + 15) + "px",
top: (top + 30) + "px", width: (206) + "px" });
},
select: function( event, ui ) {
$( "#find" ).val( ui.item.value );
$(":header.title").html(ui.item.value);
var new_url = ui.item.href; // instead of adding 'statistics', by using location.hash, it wont be necessary unlike using pushState()
location.hash = new_url;
return false;
}
})
.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "<br />" + item.desc + "</a>" )
.appendTo( ul );
};
Actually this works perfectly fine on Firefox and Chrome, it behaves just like what it exactly behaves on the sample given here, I just merely copied and modified it according to what I wanted. But on IE9, the item.desc which shows up on other browsers is not visible on IE9. I think the code to start with fixing is the last part, the part which appends the suggestions of the autocomplete. Can someone help me out here? Cheers!
You need to upgrade bgiframe.min.js to a later version (3.0 works fine)
https://github.com/brandonaaron/bgiframe
Create a new css class to override the existing jquery ui autocomplete "position":"absolute"
.ui-autocompelte{
"position": "absolute"
....
....
}
New CSS Class
.ui-autocomplete-ie9-fix { position: relative !important; }
and apply this css class after
$("#find").autocompelte({
........
.......
});
if (!$.browser.msie || ($.browser.msie && $.browser.version != 9)) {
$("ul.ui-autocomplete").addClass("ui-autocomplete-ie9-fix");
}
Add below tag after head tag
<meta http-equiv="X-UA-Compatible" content="IE=8" />

I want to propose an autocomplete list (jquery ui 1.8) with some words in bold font.
The JSON source looks like :
{"especes":[{"fk_sp":number,"nom_espece":name,"nom_valide":0 or 1}].
My script is like that :
$(function(){
$('#id').autocomplete({
source: function(request, response) {
$.getJSON("fichier.php", {
term: request.term
}, function(data) {
var array = data.error ? [] : $.map(data.especes, function(m) {
return {
label: m.nom_espece,
value: m.fk_sp,
valid: m.nom_valide
};
});
response(array);
});
},
select: function (event, ui) {
$("#espece").val(ui.item.label);
$("#fk_sp").val(ui.item.value);
}
}).data( "ui-autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( item.valid == '1' ? "<b>" + item.label + "</b>" : item.label)
.appendTo( ul );
};
});
If I use :
.data( "ui-autocomplete" ) => I have the good selectable list without the bold lines,
.data( "ui-Autocomplete" ) ou .data( "uiAutocomplete" ) => nothing works,
and if I juste write ._renderItem without .data( "ui-autocomplete" ) => I have a pretty list with the good names in bold, but I can't select any name of the list !
I don't find where is my error (I suppose it is somwhere with the "select :" part).
This is my code which render json in format {"11":"xyz","14":"abc"}
def index
if params[:term] != nil
#products = Hash[current_user.search(params[:term]).map{|product| [product.id,product.name]}]
render json: #products.to_json
end
end
This is the javascript where I am updating div #results with autocomplete result. What I want is to make xyz and abc link with the ids associated with it but I am not able to figure out why I am losing ids all I am getting in results as xyz and abc`.
$(document).ready(function(){
$("#search").autocomplete({
//source: $('#search').data('autocomplete-source'),
source: "entities#index",
open: function(e, ui) {
var list = '';
var results = $('ul.ui-autocomplete.ui-widget-content a');
var ent_id = results.html()
results.each(function() {
list += '<a href= '+$(this).html()+'/'+ent_id+ '>' +$(this).html()+'</a>'+ '<br />';
});
$('#results').html(list);
}
})
} )
Right now above javascript code is not working as required because i am not able to get ids.
Thanks
I found a soulution for it.
$(document).ready(function(){
$( "#search" ).autocomplete(
{
source:"entities#index",
select: function( event, ui ) {
$( "#search" ).val( ui.item[1] );
$( "#results").empty();
$( "#results" ).append( '<a href= '+"entities"+'/'+ui.item[0]+ '>' +ui.item[1]+'</a>' );
return false;
}
}).data( "ui-autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item[1] + "</a>" )
.appendTo( ul );
};
} )
As you can see here: http://jsfiddle.net/rA4CB/6/
When I make the drop in the overlapped area it is received in both droppables, greedy doesn't work when the items are siblings. Is there any way to block the reception on droppables lower in the zIndex?
BTW, mouseOver won't fire for the droppable element as the mouse is actually over the draggable element.
relevant JS:
$(function() {
$( "#draggable" ).draggable();
$( "#droppable" ).droppable({
tolerance:'pointer',
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )
.find( "p" )
.html( "Dropped!" );
}
});
$( "#droppable2" ).droppable({
tolerance:'pointer',
greedy:true,
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )
.find( "p" )
.html( "Dropped!" );
}
});
});
Okay, so I spend an hour trying to figure it out, then as soon as I ask I then find my answer
http://jsfiddle.net/rA4CB/7/
Modified the JS to the following:
$(function() {
$( "#draggable" ).draggable();
$( "#droppable" ).droppable({
tolerance:'pointer',
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )
.find( "p" )
.html( "Dropped!" );
}
});
$( "#droppable2" ).droppable({
tolerance:'pointer',
greedy:true,
drop: function( event, ui ) {
$( this )
.addClass( "ui-state-highlight" )
.find( "p" )
.html( "Dropped!" );
},
over: function(event, ui){
$( "#droppable" ).droppable( "disable" )
},
out: function(event, ui){
$( "#droppable" ).droppable( "enable" )
}
});
});
$( "#droppable" ).droppable({
greedy: true,
drop: function( event, ui ) {
if(ui.helper.is(".dropped")) {
return false;
}
ui.helper.addClass(".dropped");
}
});
Just set a css class on ui.helper of draggable. If the draggable has been accepted once, it will be refused by all other droppables (Could be done with the droppable "accept" parameter,too , like accept : ":not(.dropped)" and the class added to ui.draggable).
If you have a number of droppable in a container area then what????
You must re think for that problem. Greedy works for only parent to child relationship not in siblings. So you must edit droppable js or put your own logic for it.
So if you have a numbers of droppable then you must write some extra code to handle dropping on perfect droppable as it is in this example A number of siblings droppables
For making perfect siblings droppable modify your droppbale as below
var topElement = undefined;
var topElementArray = Array();
$( "#draggable" ).draggable();
$( ".droppableBox" ).droppable({
activeClass: "active-droppable",
tolerance:'pointer',
over: function( event, ui ) {
// This is for only show a message that z-index must be required for proppable
// you can remove it after testing or after development
if ($(this).css("z-index") == 'auto') {
alert("Please provide z-index for every droppable.");
return;
}
//
topElement = undefined;
topElementArray = Array();
// Change it as you want to write in your code
// For Container id or for your specific class for droppable or for both
$('#demo > .droppableBox').each(function(){
_left = $(this).offset().left, _right = $(this).offset().left + $(this).width();
_top = $(this).offset().top, _bottom = $(this).offset().top + $(this).height();
if (event.pageX >= _left && event.pageX <= _right && event.pageY >= _top && event.pageY <= _bottom) {
topElementArray.push($(this).attr('id'));
}
});
},
drop: function( event, ui ) {
if (!topElement) {
topElement = determineTopElement(topElementArray);
}
if ($(this).attr('id') == $(topElement).attr('id')) {
$( this ).addClass( "ui-state-highlight" ).find( "p" ).html( "Dropped!" );
// Your code after successful dropped element on specific siblings
// Start writing code for dropped element & perfect droppable
}
}
});
determineTopElement = function(_array) {
var topElement;
var zIndexHighest = 0;
for (i = 0; i < _array.length; i++){
var element = $("#"+ _array[i]);
var z_index = $(element).css("z-index");
if( z_index > zIndexHighest){
zIndexHighest = z_index;
topElement = element;
}
}
return topElement;
}
In certain circonstances :
myjQuery.droppable({
over:function(evt,ui){
ui.draggable.attr('drg_time', this.drg_time = evt.timeStamp)
},
accept:function(draggeds){
if(draggeds.attr('drg_time'))
{
return draggeds.attr('drg_time') == this.drg_time
}
return draggeds.hasClass('acceptable_classes_here')
},
out:function(evt,ui){
// useless but cleaner
ui.draggable.removeAttr('drg_time')
}
drop:...,
})
I had the same problem and made a small plugin :)
check it out:
https://stackoverflow.com/a/16720944/1308461
I find that using #invertedSpear's method will cause UI state change which is not desirable in some cases. Here is the code.
var lastOpertion = new Date().getTime();
drop: function (event, ui) {
if (new Date().getTime() - lastOpertion < 100) return;
lastOpertion = new Date().getTime();
....
}
So, when trying to find simple solution I came up with this (and it works for me):
window.overNowOnThis = "";
window.olderOnes = [];
$obj.droppable({
accept: ".draggable_imgs",
drop: function(e, ui) {
if(window.overNowOnThis == this){
// Do whatever
}
},
over: function(event, ui){
window.olderOnes.push(window.overNowOnThis);
window.overNowOnThis = this;
},
out: function(){
var lastElem = window.olderOnes.pop();
window.overNowOnThis = lastElem;
}
});
Top element would be selected because on it "over" fires the last one. Also - if there is more than two siblings - then when moving out of element we set the last one as current. Using global "window" was for example. Better option would be using classes as it can safely keep data.
It's very similar to invertedSpear answer. I had to change it a little bit because enabling/disabling inside "over"/"out" didn't work for me .I had to do below instead
$("#droppable2").droppable({
greedy: true,
drop: function (event, ui) {
$("droppable").droppable("disable");
}
}
I had to explicitly enable"droppable" div when I needed it. For instance, enable it when starting the drag event. Eg
$("#drageMe").draggable({
start:function(event,ui){
$("droppable").droppable("enable");
}
})
try greedy option in ui dropable. see the fiddle link below for demo:
http://jsfiddle.net/creators_guru/3vT5C/embedded/result/
$( ".circles" ).droppable({
greedy: true,
drop: function( event, ui ) {
$_data = ('drgged class = ' + ui.draggable.attr('class'));
$_data1 = ('droped id = #' + $(this).attr('id'));
$('#data').html($_data + '<br/>'+$_data1);
return false;
}
});
I have got the autocomplete to work but with errors. How would i format the response code correctly?
Response Code:
{
label: "Label 1",
value: "27"
},
{
label: "Label 2",
value: "18"
},
{
label: "Dave",
value: "25"
},
{
label: "Jacqui Potatoes",
value: "17"
}
Javascript:
$("#account_search .ac_input").autocomplete({
minLength: 0,
source: base_url + "accounts/ac_results/account_name",
dataType: "json",
type: "POST",
}).data( "autocomplete" )._renderItem = function( ul, item ) {
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "<br>" + item.desc + "</a>" )
.appendTo( ul );
return $( "<li></li>" );
};
I think the .data() function is the problem although it is working somehow. I would like to access both the label and value
You've got an error in the _renderItem function (you should call .data on the newly created <li></li>):
.data( "autocomplete" )._renderItem = function( ul, item ) {
return $( "<li></li>" )
.data( "item.autocomplete", item )
.append( "<a>" + item.label + "<br>" + item.value + "</a>" )
.appendTo( ul );
};
I also replaced item.desc which did not exist on your JSON response with item.value.
As a sidenote, you may not need to override that function at all. You only need to use it if you want to change the way each item looks in the suggestion list.
Also, make sure to remove that extra comma in the options object. Additionally, the options dataType and type are not valid options anyway:
$("#account_search .ac_input").autocomplete({
minLength: 0,
source: base_url + "accounts/ac_results/account_name"
});
Example (local data source): http://jsfiddle.net/nG8Q4/
Anyone know why the following does not work?
$.each( data.d, function( index, item ) {
// creates the tabs with custom ids
$( "#tabs" ).tabs( "add", "page.aspx?id=" + item.id, item.name )
.find('>ul>li:last')
.attr('id', 'tab_' + item.id);
// creates the buttons
$( "#buttons" ).append( "<input type='button' id='buttona" + item.id + "' value='" + item.name + "'>" );
// link buttons with tabs
$( "#buttona" + item.id ).live('click', function() {
$( "#tabs" ).tabs( "select" , "#tab_" + item.id );
});
});
I am trying to assign id's to the tabs, then select the tabs using their id's.
The above does nothing when a button is clicked and it returns no errors at all.
It works fine when using the index as shown below, but I need to use an id for various reasons:
$.each( data.d, function( index, item ) {
// creates the tabs
$( "#tabs" ).tabs( "add", "page.aspx?id=" + item.id, item.name );
// creates the buttons
$( "#buttons" ).append( "<input type='button' id='button" + index + "' value='" + item.name + "-" + index + "'>" );
// link buttons with tabs
$( "#button" + index ).live('click', function() {
$( "#tabs" ).tabs( "select" , index );
});
});
You can use the index() method to get the index of the tab from the id of its header:
$("#button" + item.id).live("click", function() {
$("#tabs").tabs("select", $("#tab_" + item.id).index());
});
Since index() is called without arguments in the code above, it will return the index of the element relative to its siblings, i.e. the other tab headers.
you can switch the tabs with the id of the tab:
var $tabs = $("#tabs").tabs();
$("button").click(function() {
$tabs.tabs( "select", "#tabs-6" );
});
It seems to me that .index() returns an index from 1 so that if I have 3 tabs and want to select the third one, I should return :
$("#button" + item.id).live("click", function() {
$("#tabs").tabs("select", $("#tab_" + item.id).index()-1);
});
