vanilla JS for循环问题

Question

Throughout for-loop in rosteringArray(), the array is should be like this.

array[0] = startDate (in form of milliseconds)

array[1] = startDate (in form of milliseconds) + 86400000

...

array[array.length-1] = endDate (in form of milliseconds)

But it doesn't.

how can I develop this code?

 var rosteringArray = function(yy1, mm1, dd1, yy2, mm2, dd2){ var date = new Date(yy1,mm1,dd1); var sDate = new Date(date); var timeStart = date.getTime() + 86400000*9; // var date = new Date(yy2,mm2,dd2); var sDate = new Date(date); var timeEnd = date.getTime() + 86400000*9; var end = timeStart; var start = timeEnd; var countDateBetween = (end - start)/86400000 +1; var array = new Array; for (var g = 0; g < countDateBetween; g++){ for (var h =setStart; h < setEnd; h=h+86400000){ array[g] = h; return array; } } } console.log(rosteringArray(2020,0,1,2020,0,03));

Answer 1

You've mixed propery values:

var end = timeStart; var start = timeEnd;

and you don't need second loop, which will always set last day value for all properties in array.

Take a look at the working snippet:

 var rosteringArray = function(yy1, mm1, dd1, yy2, mm2, dd2){ var date = new Date(yy1,mm1,dd1); var sDate = new Date(date); var timeStart = date.getTime() + 86400000*9; // var date = new Date(yy2,mm2,dd2); var sDate = new Date(date); var timeEnd = date.getTime() + 86400000*9; var end = timeEnd; var start = timeStart; console.log(start); console.log(end); var countDateBetween = (end - start)/86400000 +1; console.log(countDateBetween); var array = new Array; var h =start; for (var g = 0; g < countDateBetween; g++){ array[g] = h; h=h+86400000; } return array; } console.log(rosteringArray(2020,0,1,2020,0,03));
