获取不带小数的整数[重复]

Question

我正在运行此脚本来获取两个日期之间的差异，但结果带有小数。我怎样才能只得到整数？谢谢！

<script type="text/javascript">
var date1 = new Date("01/28/2019"); 
var date2 = new Date(); 
var Difference_In_Time = date2.getTime() - date1.getTime(); 
var Difference_In_Days = Difference_In_Time / (1000 * 3600 * 24); 
document.write(+ Difference_In_Days); 
</script>

我用这段代码得到的结果是 752.5539394675926

Answer 1

使用 parseInt 函数：

parseInt(Difference_In_Days);
