this is my first post, so my deepest excuses if something went wrong :)
I have a little html-control to write and biggest problem is ie6-8 support. There are no alternatives to skip ie6-8 support at all :( So after searching a while, I did found Raphael and it allows me to create custom shapes defined in SVG file. I need to attach 'mouseover' event and select element on hover. Event working great but I did find BIG problems in VML hover behavior.
Code was simplified to RAW html with VML shape.
<html xmlns:v="urn:schemas-microsoft-com:vml">
<head>
<style>v\: * { behavior:url(#default#VML); antialias: false; }</style>
</head>
<body>
<div id="message">hovered: nope</div>
<v:oval id="oval" style="width:100px; height:75px" fillcolor="#bbb"></v:oval>
<script>
var messageElm = document.getElementById('message');
var ovalElm = document.getElementById('oval');
ovalElm.attachEvent('onmouseover', function () { messageElm.innerText = 'hovered: yep'; });
ovalElm.attachEvent('onmouseout', function () { messageElm.innerText = 'hovered: nope'; });
</script>
</body>
</html>
If you try to move mouse over oval element you can noticed that rendered shape is not same as hover shape. I mean, hover triggers 2-3px from rendered shape (not from each side).
So question is: how to disable that virtual area (if it is possible at all)?
i had the same issue and i tried usemap;
first i create a map on a transparent png8 which covered the vml
this.dom.insertAdjacentHTML("AfterBegin",'<map name="'+_id+'"></map><img id="'+_id+'" src="'+transparent.png+
'" style="position:absolute;width:'+dom.clientWidth+';height:'+dom.clientHeight+'" />');
var map = this.dom.getElementsByTagName('map')[0];
this.dom.appendChild(map);
this.map = map;
then get the shape attach to an area; map it;
i made poly demo only;
function _getMap(shape){
this._map = this._map || {};
if(this._map[shape.id]){
}else if(shape.nodeName == 'shape'){
var arrDots = shape.childNodes[0].v.match(/(\d+),(\d+)/g)
this._map[shape.id] = _polyMap(arrDots);
}
return this.map[shape.id]
}
function _polyMap(arrDots){
var map = this.map;
var area = document.createElement('area');
area.setAttribute('shape',"poly");
area.setAttribute('coords',arrDots.join(','));
area.setAttribute('href','##');
area.setAttribute('alt','##');
map.appendChild(area);
}
then you can bind event on it;
function _onIE(shape, evtname, fn){
this._getMap(shape).attachEvent('on'+evtname, fn);
}

Is it possible to add a model(say ,a mobile phone) using three.js in html5 canvas and then make it customizable like adding text,image etc.( on mobile ) using any canvas library,so as to make an interactive 3d model.
Thanks.
You could use a library called Dat.GUI, which allows you to create a quick user interface that can accept plain text input fields, drop downs, select boxes, as well as numerical sliders. Here's an example of it being used with a text input field, which you could use to input a texture/image URL.
It's a really powerful library that can be further styled with CSS, if needed. This is all the code you need to get up and running (as you can see below, the object's properties get modified directly by Dat.GUI via invoking gui.add(object, 'property')):
<script type="text/javascript" src="dat.gui.js"></script>
<script type="text/javascript">
var FizzyText = function() {
this.message = 'dat.gui';
this.speed = 0.8;
this.displayOutline = false;
this.explode = function() { ... };
// Define render logic ...
};
window.onload = function() {
var text = new FizzyText();
var gui = new dat.GUI();
gui.add(text, 'message');
gui.add(text, 'speed', -5, 5);
gui.add(text, 'displayOutline');
gui.add(text, 'explode');
};
</script>
Yes. Three.js uses a canvas to render the 3D things and you can use any HTML tools to make the rest of that web page how you want.
I want to reduce them to a maximum 200px width and keep the same layout with the 10px spacing the photos have. Also I don't want to style the posts to be that wide and use overflow:hidden that will only cut off the photosets.
jQuery Solution
For this solution you will need the latest version of jQuery and the jQuery plugin imagesLoaded included in the head of the theme before the following:
<script type="text/javascript">
$(document).ready(function() {
$('iframe.photoset').each(function() {
var i = this;
$(i).attr("onload", "ps_resize(this)");
var s = $(i).attr("src");
s = s.replace(/\/500\//, "/200/");
$(i).attr("src", s);
});
});
function ps_resize(i) {
$(i).contents().find("body").imagesLoaded(function() {
$(i).attr("width", 200);
$(i).attr("height", $(this).height());
});
return false;
}
</script>
What Solution Does
When the DOM is ready, find all the photoset iFrames
For each iFrame...
set the "onload" attribute to your frame resizing function
get the frame's source url, change the size (e.g. 500) to 200
set the frame's source url (this will cause it to reload with a smaller photoset)
In the resizing function...
wait for the images to load
set the frame width to 200
set the frame height to the new height of the photoset
Additional Code for Infinite Scroll
If you are using the Infinite Scroll jQuery Plugin, you will need to additionally include this in your success callback function:
...
$(newElements).find('iframe.photoset').each(function() {
var i = this;
$(i).attr("onload", "ps_resize(this)");
var s = $(i).attr("src");
s = s.replace(/\/500\//, "/200/");
$(i).attr("src", s);
});
...
Obviously, if you're using Infinite Scroll, I would suggest defining a function that is called on each iFrame on both the initial load and the scroll so you don't have repeated code to maintain.
I'm trying to figure out how to manually trigger events for Leaflet polygons (loaded via GeoJSON).
In a nutshell, I have a Leaflet map with numerous polygons. I also have a regular hyperlink outside of the map that when clicked, should trigger a mouseover event (or any event really) on a particular polygon.
How do I assign ID's to all of my polygons so that I can bind hyperlink(s) to a specific polygon's event? Or is that even the most logical way of doing this?
Ultimately, I'm trying to create a map with numerous polygons along with an HTML table of text labels that are associated to each polygon. When clicking on the HTML table text, I'd like to trigger events on the map polygons (and vice versa). I just don't know how to reference each polygon.
Here is my very simplified HTML:
<body>
<div id="map" style="height: 550px; width:940px"></div>
Click to trigger a specific polygon mouseover event
</body>
Here is my very simplified JS:
$(document).ready(function () {
// build the map and polygon layer
function buildMap(data) {
var map = new L.Map('map');
var cloudmadeUrl = 'http://{s}.tile.cloudmade.com/***yourkeyhere***/66267/256/{z}/{x}/{y}.png',
cloudmadeAttribution = '',
cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18, attribution: cloudmadeAttribution});
var mapLoc = new L.LatLng(43.675198,-79.383287);
map.setView(mapLoc, 12).addLayer(cloudmade);
var geojsonLayer = new L.GeoJSON(null, {});
geojsonLayer.on("featureparse", function (e){
// apply the polygon style
e.layer.setStyle(polyStyle);
(function(layer, properties) {
layer.on("mouseover", function (e) {
// change the style to the hover version
layer.setStyle(polyHover);
});
});
layer.on("mouseout", function (e) {
// reverting the style back
layer.setStyle(polyStyle);
});
layer.on("click", function (e) {
// do something here like display a popup
console.log(e);
});
})(e.layer, e.properties);
});
map.addLayer(geojsonLayer);
geojsonLayer.addGeoJSON(myPolygons);
}
// bind the hyperlink to trigger event on specific polygon (by polygon ID?)
$('#testlink').click(function(){
// trigger a specific polygon mouseover event here
});
});
OK, I've figured it out.
You need to create a click event for each polygon that opens the popup, and assign a unique ID to each polygon so you can reference it later and manually trigger its popup.
The following accomplishes this:
var polyindex = 0;
popup = new L.Popup();
geojsonLayer = new L.GeoJSON(null, {});
geojsonLayer.on("featureparse", function (e){
(function(layer, properties) {
//click event that triggers the popup and centres it on the polygon
layer.on("click", function (e) {
var bounds = layer.getBounds();
var popupContent = "popup content here";
popup.setLatLng(bounds.getCenter());
popup.setContent(popupContent);
map.openPopup(popup);
});
})(e.layer, e.properties);
//assign polygon id so we can reference it later
e.layer._leaflet_id = 'polyindex'+polyindex+'';
//increment polyindex used for unique polygon id's
polyindex++;
});
//add the polygon layer
map.addLayer(geojsonLayer);
geojsonLayer.addGeoJSON(neighbourhood_polygons);
Then to manually trigger a specific layers click event, simply call it like this:
map._layers['polyindex0'].fire('click');
Everything between the square brackets is the unique ID of the layer you want to trigger. In this case, I'm firing the click event of layer ID polyindex0.
Hope this info helps somebody else out!
So, quick update.
Just call fireEvent (or its alias fire) on whatever layer you need.
You don't need to risk ._private[Vars], just get a reference to the target layer and fire away, e.g.
var vectorLayer = map.getLayer('myVectorLayer');
vectorLayer.fire('click');
function clickMarker(i){
var popupContent = "content here or html format",
popup = new L.Popup({offset:new L.Point(0,-28)});
popup.setLatLng(LatLng);
popup.setContent(popupContent);
map.panTo(LatLng);
map.openPopup(popup); }
i = got a corresponding coordinate which is LatLng
I'm trying to load a map as per the example in the Google documentation, but it's not loading. I tried using resize, but it's not loading correctly. This map is behind a tab rendered with the Prototype JavaScript Framework which magento uses. It loads correctly when not behind a tab.
<style type="text/css">
#map_container { height:500px; width:700px;margin:0;}
</style>
<div id="map_container">
<div id="map_canvas" style="width:500px;height:500px;"></div>
</div>
<script type="text/javascript"
src="http://maps.googleapis.com/maps/api/js?key=APIKEY&sensor=true">

<script type="text/javascript">
Event.observe( window, "load", function() {
var myOptions = {
center: new google.maps.LatLng(-34.397, 150.644),
zoom: 6,
mapTypeId: google.maps.MapTypeId.ROADMAP
};
var map = new google.maps.Map(document.getElementById("map_canvas"),
myOptions);
;
google.maps.event.trigger(map, "resize");
});
</script>
The map is shown with grey parts that cover most of the map and the UI elements are not fully initialized. I tried using google.maps.event.trigger(map, "resize");, but it does not seem to do anything. This div is inside a lot of divs.

trouble way
1. Created Map
2. Tab showed (not loads all tiles)
best way
1. Tab showed
2. Created Map
I had the same problem as you. But I managed to find the solution with this simple code.
First, go to the file where you put the tab template, search for the <li> tag that load your map tab and put this inside:
<li onclick="reloadmap()">
And in the map script right after the
google.maps.event.addDomListener(window, 'load', initialize);
put this:
function reloadmap(){
//when you resize the map, you lose your zoom and your center
//so you need to get them again here
z = map.getZoom();
c = map.getCenter();
google.maps.event.trigger(map, 'resize');
//and set them again here
map.setZoom(z);
map.setCenter(c);
}
I have an image on my page and want that it change the position on mouseover or on click, so I tried several things but I cant find the right start.
So I started to change the top-position but that's not working, I would like that on mouseover the image it jumps to position x/y (maybe random x/y) if I mouseover it again it will jump to another position.
$('#image').one('click', function () {
$(this).css( 'top' : '+=200' );
});
But that's not working so please someone could give me some input that I can figure out what to do?
Note that while setting values for top, jQuery will not automatically get the value of top set previously and add 200 to it(like a normal programming language). You could have seen this as an error in executing if you try to see in a console. You can get the value of top first and then add 200px to it and then set it again.
This should work:
$('#image').one('click', function () {
var top = parseInt($(this).css("top"));
$(this).css( 'top' , top+ 200);
});
I had to parse the string to an integer returned by css, you could also substitute that extra operation by some method that returns only the value and not the value with "px" added to it, dunno if there is one already.
Try something like this:
<html>
<head>
<script type="text/javascript">
function switchPos(obj)
{
var divobj = document.getElementById('div1')
var x = divobj.offsetHeight - obj.height - 5;
var y = divobj.offsetWidth - obj.width - 5;
var randomx = Math.floor(Math.random()*x+1);
var randomy = Math.floor(Math.random()*y+1);
obj.style.top = randomx + 'px';
obj.style.left = randomy + 'px';
}
</script>
</head>
<body>
<div id="div1" style="width: 800px; background: red;">
<img src="image.jpg" style="position:relative;" onmouseover="switchPos(this);" onmouseout="switchPos(this);"/>
</div>
</body>
</html>
