js比较日期时间的大小

var myDate = new Date();

var timed = myDate.toLocaleDateString();

var oDate1 = new Date(item.express_time.substring(0, 10));

var oDate2 = new Date(timed);

if (oDate1.getTime() > oDate2.getTime()) {

alert('没有');

} else {

//alert('超过有效期');

}

 

 

比较相等，格式化日期格式

var myDate = new Date();

var timed = myDate.toLocaleDateString();

var tt = "2016-10-18";

var tttt = "2016/10/18";

var oDate1 = new Date(tt.replace(/-/g, "/"));

var oDate2 = new Date(tttt.replace(/-/g, "/"));

alert(oDate1.getTime());

alert(oDate2.getTime());

if(oDate1.getTime()==oDate2.getTime()){

alert("相等");

} else if (oDate1.getTime() > oDate2.getTime()) {

alert("第一个大");

} else {

alert("第二个大");

}
