当尝试添加url params时,Jquery添加哈希符号

I have problem when i try to add new params in existing url with location.hash. After adding new two params hash sign is automaticly added to url #

I have link: http://work.example.rs/index.php/profile/photos on click i open new modal window where i load full size image and add new param to url like photo_id and photo_guid

preview: function() {
    $('body').on('click', '#open-picture-modal', function (e) {
        e.preventDefault();
        var $this = $(this);
        var guid = $this.data('guid');
        var photo_id = $this.data('id');

        var url = baseurl + '/picture/preview/?pgid='+guid+'&pid='+photo_id;

        location.hash = "&pgid="+guid+"&pid="+photo_id; // <-- Here is line 

    });
},

After open modal url is changed like this: http://work.example.rs/index.php/profile/photos#&pgid=E10B6F66-9686-9E29-55BA-3C197004F608&pid=6

In this url u can see # in url is added i dont know whay?

Html:

<?php $image_path = upload_userdata_url() .'/'. $photo->owner_id .'/'.'photos/'.$photo->photo_guid .'/'. $photo->photo_name;?>
<a href="<?= $image_path;?>" class="thumbnail" data-guid="<?= $photo->photo_guid; ?>" data-id="<?= $photo->photo_id; ?>" id="open-picture-modal" data-gallery>
<div class="uiMediaThumbImg" style="background-image: url(<?=$image_path;?>);"></div>
</a>

You are using hash which append the # symbol to url. You can user History API provided by HTML5

replace your line

location.hash = "&pgid="+guid+"&pid="+photo_id;

to

window.history.pushState('', '', "&pgid="+guid+"&pid="+photo_id);
