When I put OpenLayers map in a dialog, the zoom wheel seems not working. Also, when trying to resize the dialog, it is not that smooth. How to solve the two problems?
Here is the fiddle http://jsfiddle.net/Ja7v2/2/
var div = $('<div />')
.attr('id', 'map')
.css({width:800,height:600})
.appendTo($('body'));
//start a simple map, code from on http://openlayers.org/dev/examples/osm.html
map = new OpenLayers.Map( 'map');
layer = new OpenLayers.Layer.OSM( "Simple OSM Map");
map.addLayer(layer);
map.setCenter(
new OpenLayers.LonLat(-71.147, 42.472).transform(
new OpenLayers.Projection("EPSG:4326"),
map.getProjectionObject()
), 12
);
map.addControl(new OpenLayers.Control.Navigation({
zoomWheelEnabled: true,
}));
// initialize the jQueryUI Dialog
div.dialog({
width:800,
height:600,
title: 'My Map',
resizeStop: function(){
map.updateSize(); //to prevent drag-zoom error
},
dragStop: function(){
map.updateSize(); //to prevent drag-zoom error
}
});
seems the jQuery dialog disables scrolling by default.
Adding this line solves the (your) problem:
$('#map').css('overflow', 'hidden');
It's not the final solution, I believe, but shows you the way... :)

Given this example here: http://jqueryui.com/selectable/#display-grid I would like to make a selection without the "selection box" that appears when you click 'n drag. Namely, when I click on number 5 and drag to number 6 and then to 10 I get this:
where in fact what i would like to is drag from 5 to 6 to 10 and have only them selected without 9.
I searched the docs and couldn't find that option, and my google skills didn't bring me any luck, and I thought this must have been already done it's just so happens I can't grasp it on my own or find an existing solution, so any help here is appreciated (not saying you should do the research for me, am just hoping someone dealt with this before so he can point me to the right direction).
It also could be I'm missing the point in trying to accomplish this with jquery UI but this was the first such example I found that fits (kind of) what I want to accomplish.
First, you might want to hide .ui-selectable-helper or change the CSS:
.ui-selectable-helper{display:none;}
Next, do something like this:
$(function() {
var _mousedown = false;
$('#selectable').selectable({
start: function(event,ui){
_mousedown=true;
},
stop: function(event,ui){
_mousedown=false;
$('.ui-selected').removeClass('ui-selected');
$('.selecting').addClass('ui-selected');
},
selecting: function(event,ui){
if($('.ui-selecting').length == 1)
$(ui.selecting).addClass('selecting');
$('.ui-selecting').removeClass('ui-selecting');
$('.selecting').addClass('ui-selecting');
},
unselecting: function(event,ui){
if($(ui.unselecting).hasClass('selecting'))
$(ui.unselecting).removeClass('selecting');
}
});
$('#selectable').on('mouseenter', '.ui-selectee', function(){
if(_mousedown)
$(this).addClass('selecting');
});
});

Let me know if you have any questions!
***UPDATE:***
.selectable() is not able to do what you are looking for. However, here is something I created. Hope it helps!
JAVASCRIPT:
$(function() {
var _mousedown = false,
_last=null;
$('#selectable li').mousedown(function(){
_mousedown = true;
$('.ui-selected').removeClass('ui-selected');
$('#selectable li').attr('unselectable', 'on').css('user-select', 'none');
$(this).addClass('ui-selecting');
}).mouseup(function(){
_mousedown=false;
$('.ui-selecting').addClass('ui-selected').removeClass('ui-selecting');
$('#selectable li').removeAttr('unselectable style');
}).mouseenter(function(){
if(_mousedown){
if($(this).hasClass('ui-selecting'))
$(_last).removeClass('ui-selecting');
$(this).addClass('ui-selecting')
}
}).mouseleave(function(){
if(_mousedown){
_last = $(this)[0];
$(this).addClass('ui-selecting');
}
});
});

***UPDATE #2:***
If you want to use this on a mobile device, I recommend changing up the format entirely to avoid any possible pitfalls. Here is how I would go about it:
JAVASCRIPT:
$(function() {
var _clicked = false;
$('#btn_select').click(function(){
_clicked = false;
$(this).hide();
$('#selectable li').removeAttr('unselectable style');
$('.ui-selecting').addClass('ui-selected').removeClass('ui-selecting');
});
$('#selectable li').click(function(){
if(!_clicked){
_clicked = true;
$('.ui-selected').removeClass('ui-selected');
$('#selectable li').attr('unselectable', 'on').css('user-select', 'none');
$('#btn_select').show();
}
if($(this).hasClass('ui-selecting')){
$(this).removeClass('ui-selecting');
}else{
$(this).addClass('ui-selecting');
}
});
});
*NOTE: you might want a $('body').click() to act as the end_selection button.
DEMO:
http://jsfiddle.net/dirtyd77/7UVNS/13/
This doesn't answer the original question, but it does show how to access the helper div of the selectable widget.
var helper = $( "#selectable" ).selectable('widget').data().uiSelectable.helper;
helper.css( { border:'none' } );
I'm working with jquery-ui. I can create elements with titles and show the titles. However on a click, I would like to take the title and populate another div (this is because touch enabled devices do not have tooltips). I can get a click event, but I can't get the title while in the click event.
$("div").click(function( event ) {
// just to prove that we are entering this event
$("#preShow").html ( Date() );
// show the title
var toolTip = this.attributes.title.value;
$("#show").html ( toolTip );
// just to prove that there was no crash
$("#postShow").html ( Date() );
});
I have also tried using
var toolTip = $(this).attr ("title");
Here is the jsfiddle showing the problem
http://jsfiddle.net/jK5xQ/
The same code works if I create an HTML file and run it in Firefox with a breakpoint at the first line of the click event. Has anyone experienced this?
This is because jQueryUI's Tooltip removes the title and uses it. Try going about it like this...
$(document).ready(function () {
$( document ).tooltip( {
track: true,
content: function() {
return $( this ).attr( "title" );
}
});
$('div').click(function(){
$('#show').html($('#' + $(this).attr('aria-describedby')).children().html());
});
});

Let me know if you have any questions!
is there a way to manually open close the jquery ui tooltip? I just want it to react to a click event toggling on/off. You can unbind all mouse events and it will rebind them when calling .tooltip('open'), even though that should not initialize or set events imo, since if you try to run .tooltip('open') without initializing, it complains loudly about not being initialized.
jltwoo, can I suggest to use two different boolean switches to enable auto-open and auto-close? With this change your code will look like this:
(function( $ ) {
$.widget( "custom.tooltipX", $.ui.tooltip, {
options: {
autoShow: true,
autoHide: true
},
_create: function() {
this._super();
if(!this.options.autoShow){
this._off(this.element, "mouseover focusin");
}
},
_open: function( event, target, content ) {
this._superApply(arguments);
if(!this.options.autoHide){
this._off(target, "mouseleave focusout");
}
}
});
}( jQuery ) );
In this way, initializing the tooltip as:
$(someDOM).tooltipX({ autoHide:false });
it shows by itself when the mouse is over the element but you have to manually close it.
If you want to manually control both open and close actions, you can simply use:
$(someDOM).tooltipX({ autoShow:false, autoHide:false });
If you want to just unbind the events and woudn't like to make your own custom tooltip.
$("#some-id").tooltip(tooltip_settings)
.on('mouseout focusout', function(event) {
event.stopImmediatePropagation();
});
$("#some-id").attr("title", "Message");
$("#some-id").tooltip("open");
mouseout blocks the tooltop disappearing by moving the mouse cursor
focusout blocks the tooltop disappearing by keyboard navigation
The tooltip have a disable option. Well i used it and here is the code:
$('a').tooltip({
disabled: true
}).click(function(){
if($(this).tooltip('option', 'disabled'))
$(this).tooltip('option', {disabled: false}).tooltip('open');
else
$(this).tooltip('option', {disabled: true}).tooltip('close');
}).hover(function(){
$(this).tooltip('option', {disabled: true}).tooltip('close');
}, function(){
$(this).tooltip('option', {disabled: true}).tooltip('close');
});
Related to my other comment, I looked into the original code and achieved manual open/close by extending the widget and adding a autoHide option with version JQuery-UI v1.10.3. Basically I just remove the mouse listeners that were added in _create and the internal _open call.
Edit: Separated autoHide and autoShow as two separate flags as suggested by #MscG
Demo Here:
http://jsfiddle.net/BfSz3/
(function( $ ) {
$.widget( "custom.tooltipX", $.ui.tooltip, {
options: {
autoHide:true,
autoShow: true
},
_create: function() {
this._super();
if(!this.options.autoShow){
this._off(this.element, "mouseover focusin");
}
},
_open: function( event, target, content ) {
this._superApply(arguments);
if(!this.options.autoHide){
this._off(target, "mouseleave focusout");
}
}
});
}( jQuery ) );
Now when you initialize you can set the tooltip to manually show or hide by setting autoHide : false:
$(someDOM).tooltipX({ autoHide:false });
And just directly perform standard open/close calls in your code as needed elsewhere
$(someDOM).tooltipX("open"); // displays tooltip
$(someDOM).tooltipX("close"); // closes tooltip
A simple hotfix, until I have the time to do official pull request, this will have to do.
Some compilation from other SO questions.
Example
Show tooltip on hint click, and hide tooltip on elsevere click
$(document).on('click', '.hint', function(){ //init new tooltip on click
$(this).tooltip({
position: { my: 'left+15 center', at: 'center right' },
show: false,
hide: false
}).tooltip('open'); // show new tooltip
}).on('click', function(event){ // click everywhere
if(!$(event.target).hasClass('hint'))
$(".hint").each(function(){
var $element = $(this);
if($element.data('ui-tooltip')) { // remove tooltip only from initialized elements
$element.tooltip('destroy');
}
})
});
$('.hint').on('mouseout focusout', function(event) { // prevent auto hide tooltip
event.stopImmediatePropagation();
});
I have seen only a couple variants on this question asked a couple other places, notably here and here.
Basically, I have a checkers gameboard where each square on the board is a droppable and each gamepiece is a draggable. Each square can only have one piece on it at a time, and I am trying to toggle the enable/disable method depending on whether there's a piece on the square or not.
Here's a link to what I've got so far: http://jsbin.com/ayalaz, and below is the most pertinent code.
function handleDrop(e, ui) {
var tileNumber = $(this).data('tile');
// Make the gamepiece snap into the tile
ui.draggable
.data({ // WHAT IF PIECE IS SET BACK DOWN IN SAME TILE... CHECK FOR IT!
'preRow': ui.draggable.data('curRow'),
'preCol': ui.draggable.data('curCol'),
'curRow': $(this).data('row'),
'curCol': $(this).data('col')
});
$(this).append($(ui.draggable));
ui.draggable
.position({
of: $(this),
my: 'left top',
at: 'left top'
});
$(this).droppable('disable');
//console.log("Gamepiece set down at: (" + $(this).data('row') + "," + $(this).data('col')+ ")");
}
function handleOut(e, ui) {
// HOW TO TOGGLE DROPPABLE??
$(this).droppable('enable');
}
Any advice?
Thanks in advance!
Jeremy
It looks like you are successfully disabling droppable on a tile after the first drop event. Your problem is that you are not initially setting droppable to disabled on the initial set of occupied tiles.
After you've created your game board and pieces, this should accomplish that, assuming my CSS selector accurately reflects your structure:
$('div.gamePiece').parent().droppable("option", "disabled", true);
Note that this is different from the syntax to change droppability in the initial options. From the jQuery UI droppable documentation:
//initialize
$( ".selector" ).droppable({ disabled: true });
//setter
$( ".selector" ).droppable( "option", "disabled", true );
Edit
It appears I was wrong about $(this).droppable('disable'); and $(this).droppable('enable'); jquery-ui does have alias functions for enable and disable.
enable: function() {
return this._setOption( "disabled", false );
},
disable: function() {
return this._setOption( "disabled", true );
},
I asked my question on gis.stackexchange.com because of its geo nature, but I figured I would have a larger response here. https://gis.stackexchange.com/q/18327/3773
I have been trying to utilize the jQuery UI Slider to control layer opacity in OpenLayers but I have an issue when trying to set the "value" option to anything other than the "max" value.
What I would like to see is the setOpacity method change my layer's opacity to 20% onload. However, the slider is shown in the correct position but the layer displays the "max" value of opacity (100%/opaque).
I need to force the webpage to setOpacity onload, but I am not familiar on how to do this.
Removed the any unnecessary code. Your help is much appreciated!

The callback of the slider is not called onLoad. To trigger the event manually, see Trigger a jQuery UI slider event for an example.
Though, it would be better to your layer with an opacity of 0.20. You can achieve that by adding the property opacity to your layers options.
{
isBaseLayer:false,
transparent:true,
format:"image/png",
alpha:true,
opacity:0.20
}
.
