javascript - unable to get the data value of ajax on another page -


i'm trying update user votes database. below ajax codes returns correct rating datas. but, i'm unable alert data on page. in car_user_rating.php page have tried echo $post_rating = $_post['performance_rating'];. doesn't performance_rating data value.

i have checked console. returns rating values (4). i'm confused why doesn't data value?

ajax request

$(function () {     $('#form').on('submit', function (e) {       performance_rating = $('input:radio[name=rating]:checked').val();       e.preventdefault();       $.ajax({         type: 'post',         url: "<?=car_user_ratings?>",         data: { performance_rating: performance_rating },         success : function(data){             alert(performance_rating)          },       });     }); });

you should alert data pass in success: function()

like

     success : function(response){         alert(response);      },

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
