javascript - window.onload get something wrong -


i got information others' api,but not take out,so write in input.

 for(var x=0;x< loc.length;x++){        point[x]=new window.bmap.point(loc[x].lat, loc[x].lng);        getloc(point[x],x);           }       function getloc(pt,i){         gc.getlocation(pt, function(rs){          var addcomp = rs.addresscomponents;          var dd= addcomp.city + "" + addcomp.district + "" + addcomp.street;          var addname="address"+i;          var text="<input type='hidden' value="+dd+" name="+addname+" />";          $(".page-container").append(text);          });       }

then problems happened.

here window.load

     window.onload=function(){ var container_1_set={         chart: {             type: 'column'         },         title: {             text: 'sudden turn'         },         xaxis: {             categories: []         },         yaxis: {             min: 0,             title: {                 text: 'sudden turn times'             },             stacklabels: {                 enabled: true,                 style: {                     fontweight: 'bold',                     color: (highcharts.theme && highcharts.theme.textcolor) || 'gray'                 }             }         },         legend: {           enabled:false         },         tooltip: {             formatter: function() {                 return '<b>'+ this.x +'</b><br>'+                     this.series.name +': '+ this.y +'<br>'+                     'count: '+ this.point.stacktotal;             }         },         plotoptions: {             column: {                 cursor:'pointer',                 stacking: 'normal',                 datalabels: {                     enabled: true,                     color: (highcharts.theme && highcharts.theme.datalabelscolor) || 'white'                 },                 point:{                     events:{                         click:function(){                                 location.href="road_list.php?road="+this.category;                          }                     }                 }             }         },         series: [{             name: 'sudden turn',             data: [  <?php foreach ($result["data"] $item) {?>                 {                 y:<?php echo $item["time"];?>,                 color:"<?php echo $item["color"];?>",                 },                 <?php } ?>]         }]     };      var cat=[];     for(var i=0;i<10;i++){         var aa=$("input[name='address"+i+"']").val();         cat.push(aa);     }     console.log(cat);     container_1_set.xaxis.categories=cat;     $('#container_1').highcharts(container_1_set); };

if press f5 button,it can value , work.
when clicking on column of chart,the variable cat undefined.

window load not required. instead have document ready. no need use both.
