How to add a preloader while content load?
Question
So on start a loader should be there and as soon as weather is shown the preloader should be gone.It's using simpleweather.js plugin.
I've tried using .hide() .addClass() .Doesn't seems to work.
//JS
$(document).ready(function() {
navigator.geolocation.getCurrentPosition(function(position) {
loadWeather(position.coords.latitude+','+position.coords.longitude);
});
function loadWeather(location, woeid) {
$.simpleWeather({
location: location,
woeid: woeid,
unit: 'c',
success: function(weather) {
html = '<h1><i class="wi wi-fw wi-yahoo-'+weather.code+'"></i></h1>';
html += '<h2>'+weather.temp+'°'+weather.units.temp+'</h2>';
html += '<ul><li>'+weather.city+', '+weather.region+'</li>';
html += '<li class="currently">'+weather.currently+'</li></ul>';
$("#weather").hide().html(html).fadeIn("slow");
},
error: function(error) {
$("#weather").html('<p>'+error+'</p>');
}
});
}
});
//HTML
<body>
<div id="weather"></div>
</body>

Only as idea:
create a loading animation in your html, it should be visible by default, so user see it directly on page visit. Then hide it on "success" in your js.
<div id="loading">Loading....</div>
and js code
jQuery("#loading").hide()

To be able to show a loader, do the following. Add a div with img tag which points to the loader file.
<div id="loader" style="display:none"><img src="<path_to_loader_file>"></div>
Update your function:
function loadWeather(location, woeid) {
var load = $('#loader');
load.show();
$.simpleWeather({
location: location,
woeid: woeid,
unit: 'c',
success: function(weather) {
load.hide();
},
error: function(error) {
load.hide();
}
});
}

You can use ajaxSetup
$.ajaxSetup({
global: true,
beforeSend: function(xhr, settings) {
$('#some-overlay-with-spinner').show();
},
complete: function(xhr, status) {
$('#some-overlay-with-spinner').hide();
},
error: function(xhr, status, error) {
$('#some-overlay-with-spinner').hide();
},
timeout: 5000
});
$(document).ajaxError(function(event, jqxhr, settings, thrownError) {
$('#some-overlay-with-spinner').hide();
});
UPDATE: Try topbar as progress indicator. You can show and hide it instead of an overlay with a spinner.

add this code
<div id="loading">Loading....</div> // use a gif image loader within this div
$("#loading").show(); //before ajax request
your ajax code --here
$("#loading").hide(); // after ajax response
