I have a page with filters on top and a toggle between tile view or map view.
Every time a filter is changed I perform a search with AJAX and change the view using Mustache. On mobile the default view is the tile view with an icon on the bottom right to toggle the map. When my view is on the tile view, I change a filter (so the search triggers and filtered tiles show up), i then toggle to the map view and it is max zoomed out, and only the bottom left corner is not greyed out. It looks like this:
When I load the page, and i immediately toggle to my map view, that is also the initial view I see. But if I then change my filters and perform the search again, the map will load correctly and works perfectly. But after switching to tiles, changing filters and going back to Map view, it breaks again.
This is the HTML holder for the map:
<div id="map_canvas"></div>
jQuery:
$(document).ready(function(){
'use strict';
curr_lang = $('#curr_lang').val();
initializeElements();
//Read the query parameters & set everything up according to it
setupConfig(radiusSlider);
//Setup the listeners for the freetext input search field
setupFreetextField();
setupInterestsField();
setupLocationField();
setupDaterangeField();
setupMorefiltersField();
});
function initializeElements() {
$(window).scroll(function() {
var volunteer = $('#map_canvas');
var offset = volunteer.offset();
top = offset.top;
state = $('.footer').offset().top;
var bottom = $('#map_canvas').offset().top;
if ($(window).scrollTop() + volunteer.height() + 134 > state) {
volunteer.removeClass('fixed');
volunteer.addClass('bottom');
} else if ($(this).scrollTop() + 58 > bottom) {
volunteer.addClass('fixed');
volunteer.removeClass('bottom');
} else {
volunteer.removeClass('fixed');
volunteer.removeClass('bottom');
}
//Enable search toggle menu icon
if ($(window).width() <= 768) {
var nav = $('.navbar-wrapper');
var navOffset = nav.offset();
var filters = $('.content-filters');
var filtersOffset = filters.offset().top;
var searchToggle = $('.search-filter-toggle');

}
}

marker.bindPopup(info);

}
//console.log(boundsarray);
map.fitBounds(boundsarray);
map.addLayer(mcg);
}
EDIT: I added the complete code after trying to add map.invalidateSize(); on the map toggle function. But it results in the same.
The setupMap() function is called at the end of my AJAX success method for searching. (The vacancies parameter is the result from my AJAX method and contains the information for the tiles and as well the lat/lon of the vacancy)
