How to escape "&" character in dryml? - ruby-on-rails

I've got this in my application.dryml file:

</head>
<body onload="initialize()">
<div id="map_canvas" style="width:100%; height:100%"><div param="map" /></div>

I'm getting an error "Illegal character '&' in raw string" (the param separator in the maps.googleapis.com link.
How do I escape the & character in dryml?

Strange default size in leaflet map

I have taken a working Leaflet map, but when I added a JQuery Mobile header and back button the formatting went crazy.
Initially loading the page all the contents is loaded in the upper-left-hand corner, but when the page is resized the smallest bit on a desktop, or rotated on a mobile, everything is fine.
This is what it looks like when opened:
and what it looks like after rotating (and what it should be):
Here is the code for the page

jQuery Mobile has its own way to create pages from div's, so you may better stick to JQM events.
Here is a great post of Omar which explain how to solve this (typical) issue when loading Google Maps. You should wait for pagecontainershow or use a placeholder to pre-load the maps in advance.
In my example below, you will find a variation of this approach for Leaflet which uses the same canvasHeight() function (see also the answers here: set content height 100% jquery mobile).
I noticed you are about to implement a footer button for the geo-location feature, so for your convenience i show you also a possible way to do that (credits: Getting current user location automatically every “x” seconds to put on Leaflet map?).
Please note: i had to reposition the default map attribution so it won't overlap with the footer button.
var map, actualPosition, actualAccuracy, autoUpdate;
function canvasHeight(canvas) {
var mapPage = $("#page-map"),
screen = $.mobile.getScreenHeight(),
header = $(".ui-header", mapPage).hasClass("ui-header-fixed") ? $(".ui-header", mapPage).outerHeight() - 1 : $(".ui-header", mapPage).outerHeight(),
footer = $(".ui-footer", mapPage).hasClass("ui-footer-fixed") ? $(".ui-footer", mapPage).outerHeight() - 1 : $(".ui-footer", mapPage).outerHeight(),
newHeight = screen - header - footer;
$(canvas).height(newHeight);
}
$(window).on("throttledresize orientationchange", function() {
canvasHeight("#map");
})
function onLocationFound(e) {
var radius = e.accuracy / 2;
actualPosition = L.marker(e.latlng).addTo(map);
actualAccuracy = L.circle(e.latlng, radius).addTo(map);
}
function onLocationError(e) {
alert(e.message);
}
function showLocation() {
if (actualPosition) {
map.removeLayer(actualPosition);
map.removeLayer(actualAccuracy);
}
map.locate({setView: true,maxZoom: 16});
}
function loadMap(canvas) {
map = L.map(canvas).setView([43.7178, -79.3762], 11);
L.tileLayer("https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png").addTo(map);
map.on('locationfound', onLocationFound);
map.on('locationerror', onLocationError);
// Your custom initialization
//getGeoJson();
//getTPSJson();
}
function toggleAutoUpdate() {
if (autoUpdate) {
$("#autoUpdate").removeClass("ui-btn-active");
clearInterval(autoUpdate);
autoUpdate = null;
if (actualPosition) {
map.removeLayer(actualPosition);
map.removeLayer(actualAccuracy);
}
} else {
$("#autoUpdate").addClass("ui-btn-active");
showLocation();
autoUpdate = setInterval(function() {
showLocation();
// Your custom Update
//getGeoJson();
}, 10 * 1000);
}
}
$(document).on("pagecontainershow", function(e, ui) {
if (ui.toPage.prop("id") == "page-map") {

jQuery Mobile manages the pages of your multi-pages document and resizes them appropriately when DOM is loaded.
The issue is that you have already instantiated your map with Leaflet before that event happens, so the map container (i.e. <div id="map"></div>) is not displayed yet by jQuery Mobile, and therefore its size is not computed yet by the browser.
This is a variant of map container size not being valid yet at map instantiation. See Data-toggle tab does not download Leaflet map
Since you already have a listener on window.onload, which executes after jQuery Mobile does its stuff, you could very simply call map.invalidateSize() at that moment:
window.onload = function() {
// Request Leaflet to re-evaluate the map container size
// AFTER jQuery Mobile displays the page.
map.invalidateSize();
getGeoJson();
getTPSJson();
};

OSM building and jQuery mobile

I have a problem with input "range" and OSM Buildings for leaflet maps. I used basic example from official example which works fine but if I add jquery mobile to <head> section it breaks the range input. It's strange... I was using jquery mobile input to change the leaflet map opacity and it's working. Here is my basic example:
var map = new L.Map('map');
map.setView([52.52111, 13.40988], 16, false);
new L.TileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: 'osm.org',
maxZoom: 18,
maxNativeZoom: 20
}).addTo(map);
var osmb = new OSMBuildings(map).load();
//************************************************************
var now,
date, time,
timeRange, dateRange,
timeRangeLabel, dateRangeLabel;
function changeDate() {
var Y = now.getFullYear(),
M = now.getMonth(),
D = now.getDate(),
h = now.getHours(),
m = 0;
timeRangeLabel.innerText = pad(h) + ':' + pad(m);
dateRangeLabel.innerText = Y + '-' + pad(M+1) + '-' + pad(D);
osmb.date(new Date(Y, M, D, h, m));
}
function onTimeChange() {
now.setHours(this.value);
now.setMinutes(0);
changeDate();
}
function onDateChange() {
now.setMonth(0);
now.setDate(this.value);
changeDate();
}
function pad(v) {
return (v < 10 ? '0' : '') + v;
}
timeRange = document.getElementById('time');
dateRange = document.getElementById('date');
timeRangeLabel = document.querySelector('*[for=time]');
dateRangeLabel = document.querySelector('*[for=date]');
now = new Date;
changeDate();
// init with day of year
var Jan1 = new Date(now.getFullYear(), 0, 1);
dateRange.value = Math.ceil((now-Jan1)/86400000);
timeRange.value = now.getHours();
timeRange.addEventListener('change', onTimeChange);
dateRange.addEventListener('change', onDateChange );
timeRange.addEventListener('input', onTimeChange);
dateRange.addEventListener('input', onDateChange);

For jQuery Mobile rangesliders you may use:
$(document).on("pagecreate", "#page-1", function() {
$("#date").on("change", onDateChange);
$("#time").on("change", onTimeChange);

How can I add dynamic legend to this map so that when selecting blue markers, the legend should show only a blue marker with its name and when selecting red markers it will show the red marker icon in legend.

You must clear the controls(remove all legends) and then add the desired legend again.
right before
google.maps.event.addDomListener(document.getElementById('style')[...]
add this code:
//we need a copy of all legends(nodes),
//otherwise they wouldn't be accessible when they have been removed
var clonedArray = map.controls[google.maps.ControlPosition.RIGHT_BOTTOM]
.getArray().slice();
//observe changes of the styleId
google.maps.event.addListener(layer,'styleid_changed',function(){
//clear the controls
map.controls[google.maps.ControlPosition.RIGHT_BOTTOM].clear();
//add the desired control
map.controls[google.maps.ControlPosition.RIGHT_BOTTOM]
.push(clonedArray[this.get('styleId')-1])
});
//trigger the event to initially have only the legend
//based on the selected style
google.maps.event.trigger(layer,'styleid_changed');

Right now I have a copy of the file in my root app folder, one in my view folder(called maps), right next to the index.html.erb
How can I reference the resource correctly?

put it in the my_project/public/ folder. You also want to rename the file to states.geojson.json

Using jQuery slider to change Google chart viewWindow

I have prepared a simple test case with screenshot, demonstrating my problem and am probably missing a tiny bit, just few lines of code.
I have a diagram representing wins and losses in a web game over the weeks.
I.e. the vertical axis represents the game score and the horizontal axis represents numbers of weeks.
My ajax script returns the data for 52 weeks, but I'd like to add a slider and allow users change the viewed number of weeks to any number between 12 and 52.
Can anybody please advise me, how to modify the change function?
$("#money_slider").slider({
min: 12,
max: 52,
change: function(event, ui) {
// XXX what to do here with
// hAxis.viewWindow.min and .max?
}
