Answer 1

This work for me. Override the event search:

jQuery('#Distribuidor_provincia_nombre').autocomplete({
    'minLength':0,
    'search':function(event,ui){
        var newUrl="/conf/general/provincias?pais="+$("#Distribuidor_pais_id").val();
        $(this).autocomplete("option","source",newUrl)
    },
    'source':[]
});

Answer 2

$('#txtCropname').autocomplete('Handler/CropSearch.ashx', {
    extraParams: {
        test: 'new'
    }
});

I believe you are correct in thinking your call to $("#product").autocomplete is firing on page load. Perhaps you can assign an onchange() handler to the select menu:

$("#zipcode").change(resetAutocomplete);

and have it invalidate the #product autocomplete() call and create a new one.

function resetAutocomplete() {
    $("#product").autocomplete("destroy");
    $("#product").autocomplete({
         source:"product_auto_complete.php?postcode=" + $('#zipcode').val(),
         minLength: 2,
         select: function(event, ui){... }
    });
}

You may want your resetAutocomplete() call to be a little smarter -- like checking if the zip code actually differs from the last value -- to save a few server calls.

Hope this one will help someone:

$("#txt_venuename").autocomplete({
    source: function(request, response) {
    $.getJSON('<?php echo base_url(); ?>admin/venue/venues_autocomplete', 
        { 
            user_id: <?php echo $user_param_id; ?>, 
            term: request.term 
        }, 
      response);
    },
    minLength: 3,
    select: function (a, b) {            
        var selected_venue_id = b.item.v_id;
        var selected_venue_name = b.item.label;            
        $("#h_venueid").val(selected_venue_id);
        console.log(selected_venue_id);            
    }
});

The default 'term' will be replaced by the new parameters list, so you will require to add again.

You need to use a different approach for the source call, like this:

$("#product").autocomplete({
  source: function(request, response) {
    $.getJSON("product_auto_complete.php", { postcode: $('#zipcode').val() }, 
              response);
  },
  minLength: 2,
  select: function(event, ui){
    //action
  }
});

This format lets you pass whatever the value is when it's run, as opposed to when it's bound.

jQuery("#whatJob").autocomplete(ajaxURL,{
    width: 260,
    matchContains: true,
    selectFirst: false,
    minChars: 2,
    extraParams: {  //to pass extra parameter in ajax file.
        "auto_dealer": "yes",
    },
});
