试试这个

var d = new Date();
d.setDate(d.getDate() - 1);

这将产生昨天零点的分钟精确

var d = new Date();
d.setDate(d.getDate() - 1);
d.setTime(d.getTime()-d.getHours()*3600*1000-d.getMinutes()*60*1000);

[2022年4月]:下面是一个扩展Date原型的代码片段(不污染全局命名空间)

[edit sept 2020]:一个包含之前答案的片段，并添加了一个箭头函数。

// a (not very efficient) oneliner let yesterday = new Date(new Date().setDate(new Date().getDate()-1)); console.log(`Yesterday (oneliner)\n${yesterday}`); // a function call yesterday = ( function(){this.setDate(this.getDate()-1); return this} ) .call(new Date); console.log(`Yesterday (function call)\n${yesterday}`); // an iife (immediately invoked function expression) yesterday = function(d){ d.setDate(d.getDate()-1); return d}(new Date); console.log(`Yesterday (iife)\n${yesterday}`); // oneliner using es6 arrow function yesterday = ( d => new Date(d.setDate(d.getDate()-1)) )(new Date); console.log(`Yesterday (es6 arrow iife)\n${yesterday}`); // use a method const getYesterday = (dateOnly = false) => { let d = new Date(); d.setDate(d.getDate() - 1); return dateOnly ? new Date(d).toDateString() : d; }; console.log(`Yesterday (method)\n${getYesterday()}`); console.log(`Yesterday (method dateOnly=true)\n${getYesterday(true)}`); // use Date.now console.log(`Yesterday, using Date.now\n${new Date(Date.now() - 864e5)}`); .as-console-wrapper { max-height: 100% !important; }

试试这个

var d = new Date();
d.setDate(d.getDate() - 1);

d.setHours(0,0,0,0);

会成功的

var date = new Date();

date ; //# => Fri Apr 01 2011 11:14:50 GMT+0200 (CEST)

date.setDate(date.getDate() - 1);

date ; //# => Thu Mar 31 2011 11:14:50 GMT+0200 (CEST)
