Here is an approach using str.slice(0, -n). Where n is the number of characters you want to truncate.

这是一种使用str.slice(0,-n)的方法。其中n是要截断的字符数。

var str = 1437203995000;
str = str.toString();
console.log("Original data: ",str);
str = str.slice(0, -3);
str = parseInt(str);
console.log("After truncate: ",str);
