Question

I am trying to make jquery autocomplete to be work on https (secured pages) pages but its not showing any dropdown.
I searched on this issue and found that its security issue.

can any one tell me how to turn on this autocomplete dropdown on https pages.

here is my code to jquery autocomplete :

function zipAutoCompletet(prefix) {
  jQuery("#" + prefix + "_zip").autocomplete({
    source: function (request, response) {
      jQuery.ajax({
        url: "http://ws.geonames.org/postalCodeSearchJSON",
        dataType: "jsonp",
        data: {
          style: "full",
          maxRows: 12,
          postalcode_startsWith: request.term
        },
        success: function (data) {
          response(jQuery.map(data.postalCodes, function (item) {
            return {
              label: item.placeName + (item.adminCode1 ? ", " + item.adminCode1 : "") + ", " + item.postalCode + ", " + item.countryCode,
              value: item.postalCode
            }
          }));
          jQuery('.ui-autocomplete').css('width', '188px');
        }
      });
    },
    minLength: 2,
    select: function (event, ui) {
      var myString = new String(ui.item.label);
      var address = myString.split(',')
          jQuery('#' + prefix + '_city').val(address[0]);
      jQuery('#' + prefix + '_city').addClass('activated');
      jQuery('#' + prefix + '_city').trigger('change');
      jQuery('#' + prefix + '_city').parents('.row').removeClass('error-row')
        jQuery('#' + prefix + '_city').parents('.row').addClass('ok-row')
          var countryCode = address[3] ? address[3] : address[2]
              countryCode = jQuery.trim(countryCode);
      var countryName = jQuery('#' + prefix + '_country option[value="' + jQuery.trim(countryCode) + '"]').text()
          jQuery('#countryContainer .jqTransformSelectWrapper span').html(countryName)
            jQuery('#countryContainer .jqTransformSelectWrapper').addClass('selected-jqtranform');
      jQuery('#' + prefix + '_country').parents('.row').addClass('ok-row')
        jQuery('#' + prefix + '_country').parents('.row').removeClass('error-row')
          jQuery('#' + prefix + '_country').val(jQuery.trim(countryCode))
            var stateCode = address[2] ? address[1] : '';
      stateCode = jQuery.trim(stateCode)
        if (countryCode == 'US') {
          var base = base_url;
          base = base.replace("https", "http");
          jQuery.ajax({
            url: base + "/getStateName",
            dataType: "jsonp",
            data: {
              stateCode: stateCode
            },
            success: function (data) {
              stateName = data
                jQuery('#jc_state').val(stateName);
              jQuery('#jc_state').addClass('activated');
              jQuery('#jc_state').parents('.row').removeClass('error-row')
                jQuery('#jc_state').parents('.row').addClass('ok-row')
                  jQuery('#jc_state').trigger('change');
              formValidate();
            }
          });
        } else {
          stateName = stateCode
            jQuery('#jc_state').val(stateName);
          jQuery('#jc_state').addClass('activated');
          jQuery('#jc_state').parents('.row').removeClass('error-row')
            jQuery('#jc_state').parents('.row').addClass('ok-row')
              jQuery('#jc_state').trigger('change');
          formValidate();
        }
      jQuery('#' + prefix + '_zip').parents('.row').addClass('ok-row')
        jQuery('#' + prefix + '_zip').parents('.row').removeClass('error-row');
    },
    open: function () {
      jQuery(this).removeClass("ui-corner-all").addClass("ui-corner-top");
    },
    close: function () {
      jQuery(this).removeClass("ui-corner-top").addClass("ui-corner-all");
    },
    change: function (event, ui) {
      if (ui.item === null) {
        jQuery("#" + prefix + "_zip").parents('.row').removeClass('ok-row');
        jQuery("#" + prefix + "_zip").parents('.row').addClass('error-row');
        $("#" + prefix + "_zip").val('');
      }
    }
  });
}

I am using above code for zipcode field.This code works fine on non-https pages it works fine but when I tried it with https pages it doesnt shows.

any solutions are welcome.

As I looked into the service provider they are supporting jsonp and the following sample worked

$("input").autocomplete({
    source: function (request, response) {
        $.getJSON("http://ws.geonames.org/postalCodeSearchJSON?callback=?", 
          { 'postalcode_startsWith': request.term, maxRows: 12, style: "full" }, 
          function(data) {
              if(data.postalCodes){
                  var x = $.map(data.postalCodes, function(v, i){
                      console.log(v)
                      return {
                          label: v.placeName + ' - ' + v.postalCode, 
                          v: v.postalCode
                      }
                  });
                  response(x);
              }
          }
        );        
    }
});
