Q:

initialize jQuery filter using Hash or GET-parameters

UPDATE
Due to low activity on my original question (below) I rephrase it simply like this: 
How can I initialize MIXITUP jQuery filter from other url using Hash or GET-parameters?

====
I am using MIXITUP jQuery filter for sorting several elements on one page. Is there a way to make a link from another page with one of the filers already active?The idea is to have one link for each category and also one main link for the hole page. The category link would land the visitor on the second page with the selected category filter already activated. If the visitor would choose the main link he would land on the page with all categories visible.
For example lets say I sell cables and want to have a link from index to store with HDMI activated, so that when the jump has been made the visitor lands on the store page and only sees HDMI cables, with the option of selecting other filters to see the rest of the products of course.Please ask if you need more information, sample code or anything else.. 
Thanks in advance 

A:

You can specify the filter which will take effect right when the page is loaded by using the load.filter setting like this:
$('#container').mixItUp({
  load: {
    filter: 'your filter'
  }
});

Nothing stops you from getting the value for this setting from document.location.hash property. You can check whether the hash is empty, and if it's not, use its value as a filter:
$('#container').mixItUp({
  load: {
    filter: document.location.hash == '' ? 'all' :
      ('.' + document.location.hash.substring(1))
  }
});

hash.substring(1) is needed because the string would include the # character itself, and I append . in the beginning because I think it's likely that you want to always filter by class and there's no need to include the dot in the URL.
