How to optimise my partial view loading time? (C#, MVC, jQuery)

For this feature, I want the respective tour package details (partial view.cshtml) to load in the main view (view.cshtml) as I select the different options. The problem I am facing now is that, the partial view content loads way too slowly.
For example,
Tour A package detail: New Zealand Tour (16 Day)
Tour B pacakage detail: New Zealand Tour (14 Day)
if i click onto card A, it takes a long time for New Zealand Tour (16 Day) to appear
if i click onto card B, New Zealand Tour (16 Day) will still be there, only after a long time of waiting, then it will switch to New Zealand Tour (14 Day)
sorry i tried to attach the gif demo but it doesn't allow me to upload
here are my codes:

Jquery location picker autocomplete doesn't work in bootstrap modal

I am using jquery location picker inside a bootstrap modal. It opens the map but the autocomplete suggestions are not visible.
The html and the javascript code are given below.
$timeout(function() {
$('#onboardingModal').on('shown.bs.modal', function() {
$('#mappicker').locationpicker({
location: {
latitude: 12.9715987,
longitude: 77.59456269999998
},
radius: 200,
inputBinding: {
locationNameInput: $('#locationInput')
},
enableAutocomplete: true,
autocompleteOptions: {
componentRestrictions: {country: 'in'}
},
onchanged: function (currentLocation, radius, isMarkerDropped) {
var addressComponents = $(this).locationpicker('map').location.addressComponents;
$scope.lat = $(this).locationpicker('map').location.latitude
$scope.lng = $(this).locationpicker('map').location.longitude
// updateControls(addressComponents);
},
});
});
});

</div>
</div>
Tried changing the z-index also added ui-front class of jquery, didn't work on either case.
What am I doing wrong in this?

I got the answer in one of the issues in github. Needed to add z-index to pac-container.
.pac-container{z-index:2000 !important;}

Picture:
The problem is modal Success, does it make Google Maps fail. How can I fix?
Thank you guys.

I solved the problem in another way. Using Bootstrap Alert.
Link: Alerts - Bootstrap
Remove code:
<div id="ModalMsgBoxId" class="modal fade" tabindex="-1" role="dialog">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title">
<strong id="ModalTitleId" style="margin-left: 6px; font-size: 16px;"></strong>
</h4>
</div>
<div class="modal-body">
<p>
<div id="ModalContentId" style="margin-left: 6px; font-size: 16px;"></div>
</p>
</div>
<div class="modal-footer">
<button id="normalOkId" type="button" class="btn btn-success" data-dismiss="modal">OK</button>
</div>
</div>
</div>
</div>
New code:
<center><div id="result"></div></center>
javascript:
$("#result").html('<div class="alert alert-success"><button type="button" class="close">×</button>Successfully updated record!</div>');
Now it works! I took example link: here

I did a research for this problem, ang i got the common answer, it is google.maps.event.trigger(map, "resize"); the problem is where will i put it, please help me.
Thanks

google map has problem with "display:none" parent.
initialize your map after showing modal for first time.
add a class for button or link that show modal.
$('.modal-opener-btn').one('click', function(){
//putt your code here
});
NOTICE : use "one" and dont use "on"
NOTICE : also can use modal "shown" listener, if this solution doesn't work
$('#myModal7').on('shown', function(){
//putt your code here
});
Just change bottom script tag and contents to :
<script type="text/javascript">
function init(){
var address = 'Japan';
var map = new google.maps.Map(document.getElementById('map'), {
zoom: 16
});
var geocoder = new google.maps.Geocoder();
geocoder.geocode({
'address': address
},
function(results, status) {
if(status == google.maps.GeocoderStatus.OK) {
new google.maps.Marker({
position: results[0].geometry.location,
map: map
});
google.maps.event.trigger(map, 'resize');
map.setCenter(results[0].geometry.location);
}
});
}
$('#myModal7').on('shown.bs.modal', function(){
init();
});
</script>

regarding your research you can try to use that function
inside this
$(document).ready(function(){
$('#your_modal_id').on('shown.bs.modal',function(){
google.maps.event.trigger(map, "resize");
});
});

Had the same problem and this was the solution that made my day:
Make sure that you have jQuery on the initial page that called your modal page:

bootstrap modal box open jquery location picker

I work With jquery location picker plugin for google map. now, I open map into bootstrap 3.0 modal box. This worked, But I need to: when click in save changes button show longitude and latitude in result input box.
JS:
$('#us2').locationpicker({
location: {
latitude: 46.15242437752303,
longitude: 2.7470703125
},
radius: 300,
inputBinding: {
latitudeInput: $('#us2-lat'),
longitudeInput: $('#us2-lon'),
radiusInput: $('#us2-radius'),
locationNameInput: $('#us2-address')
}
});
$(document).ready(function () {
$("#btnModal").click(function () {
//How Can I Copy myDiv here so that I can also view it in Modal
$("#myModal").modal('show');
$("#myDiv").appendTo(".modal-body");
});
$('#myModal').on('hide.bs.modal', function (e) {
$("#myDiv").prependTo("body");
})
});
HTML :
<a data-toggle="modal" href="#myModal" class="btn btn-primary">Launch modal</a>
<div class="modal" id="myModal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">Location:
<input type="text" id="us2-address" style="width: 200px" />Radius:
<input type="text" id="us2-radius" />
<div id="us2" style="width: 500px; height: 400px;"></div>Lat.:
<input type="text" id="us2-lat" />Long.:
<input type="text" id="us2-lon" />
</div>
<div class="modal-footer"> Close
Save changes
</div>
</div>
</div>
</div>
result lat: <input type="text" id="lat" />
result long: <input type="text" id="lon" />
I have result long and result lat for input/join value form modal box when click in save changes button. How to create This ?
DEMO : http://jsfiddle.net/hagR2/

Give the "save changes" btn an id :
Save changes
add a click handler to the btn that transfers the values to the main page and closes the modal :
$("#save-changes").click(function() {
$("#lat").val($('#us2-lat').val());
$("#lon").val($('#us2-lon').val());
$('#myModal').modal('hide');
})
forked fiddle -> http://jsfiddle.net/Lzv7w/

Try this out:- http://jsfiddle.net/adiioo7/hagR2/2/
JS:-
$('#us2').locationpicker({
location: {
latitude: 46.15242437752303,
longitude: 2.7470703125
},
radius: 300,
inputBinding: {
latitudeInput: $('#us2-lat'),
