Jquery

jQuery(document).ready(function() {

	jQuery.post(
	MyAjax.ajaxurl,
	{

		action : 'myajax-submit',
		information: 'weekdays'

	},
	function( data ) {
		disabled_days = data;
	}
	);
	jQuery.post(
	MyAjax.ajaxurl,
	{

		action : 'myajax-submit',
		information: 'baddates'

	},
	function( data ) {
		disabled_days2 = data;
	}
	);

	jQuery( "#date" ).datepicker("option", {
	beforeShowDay: disable,
	minDate: "0"
	});

	function disable(date){
        var day = date.getDay();
		var dmy = date.getDate() + "-" + (date.getMonth()+1) + "-" + date.getFullYear();

		 if(in_array(day, disabled_days) == true){
        	return [false, ''];
		}else if(in_array(dmy, disabled_days2) == true){
        	return [false, ''];
		}else{
          return [true, ''];
		}

      };

	function in_array (needle, haystack, argStrict) {
  		var key = '',
    		strict = !! argStrict;

  		if (strict) {
    			for (key in haystack) {
      				if (haystack[key] === needle) {
       					return true;
      				}
   			}
  		} else {
    			for (key in haystack) {
     	 			if (haystack[key] == needle) {
        				return true;
      				}
    			}
  		}

	return false;
	}
  });

Uses this to get this value to disabled_days2: ["11-2-2013","12-2-2013","13-2-2013","14-2-2013","15-2-2013","16-2-2013","17-2-2013","18-2-2013","19-2-2013","20-2-2013","21-2-2013","22-2-2013","23-2-2013","24-2-2013","25-2-2013","26-2-2013","27-2-2013","28-2-2013","1-3-2013","2-3-2013","3-3-2013","4-3-2013","5-3-2013","6-3-2013","7-3-2013","8-3-2013","9-3-2013","10-3-2013","11-3-2013","12-3-2013","13-3-2013","14-3-2013","15-3-2013","16-3-2013","17-3-2013","18-3-2013","19-3-2013","20-3-2013","21-3-2013","18-3-2013","19-3-2013","20-3-2013","21-3-2013"]. BUT the dates dosent get disabled? The disableing of the weekdays works tho. On my page i do this to call script:

wp_enqueue_script( 'my-ajax-request', plugin_dir_url( __FILE__ ) . 'js/script.js', array( 'jquery-ui-datepicker' ) );
wp_localize_script( 'my-ajax-request', 'MyAjax', array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );

When i just used php to echo the varibles it worked fine.
