how can write loop 16 digit number 0 n

i want output like:

0000000000000000 0000000000000001 0000000000000002 0000000000000003 0000000000000004 0000000000000005

tried isn't working:

for(i = 0000000000000000; < 0000000000000010; i++){     $("#testdiv").append(i); }

check out jsfiddle

<!doctype html> <html> <head lang="en">     <meta charset="utf-8">     <title></title> </head> <body>      <script>         function writenumber(n){             var nlen = n.tostring().length;             var zerolen = 16-nlen;             var arr = [];             var str = "0";             for(var z=0;z<zerolen;z++){                 arr.push(str);             }             arr.push(n.tostring());             return arr.join('');         }      window.onload = function () {           var arr = [];         for(i=0;i<11;i++){             var str = writenumber(i);             arr.push(str);         }          document.getelementbyid("testdiv").innerhtml = arr.join('<br>');      };      </script>      <div id="testdiv"></div>  </body> </html>

more efficient array. maybe doesn't matter when loop 10 items, you're going write dom 10 times if access dom inside loop instead of outside loop 1 time. small things adds up, may matter.

9. stop touching dom, damnit!

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 .
