js to find the implementation code for time difference

var date1=new Date(); //Start time

var date2=new Date(); //End time

var date3=date2.getTime()-date1.getTime() //The number of milliseconds of the time difference

//Calculate the number of days of difference

var days=Math.floor(date3/(24*3600*1000))

//Calculate the number of hours

var leave1=date3%(24*3600*1000) //The number of milliseconds remaining after counting the number of days

var hours=Math.floor(leave1/(3600*1000))

//Calculate the number of minutes of phase difference

var leave2=leave1%(3600*1000) //The number of milliseconds remaining after calculating the number of hours

var minutes=Math.floor(leave2/(60*1000))

//Calculate the phase difference seconds

var leave3=leave2%(60*1000) //The number of milliseconds remaining after counting the number of minutes

var seconds=Math.round(leave3/1000)

alert(" difference"+days+"days"+hours+"hours+" minutes+" minutes"+seconds+" seconds")

Math.floor(Math.abs(k1 - k2) / 1000 / 60 / 60 / 24 + 0.5);//Time difference rounds

document.write("Two decimal points:"+a.toFixed(2)+"<br>Four decimal points"+a.toFixed(4));

The above js time difference implementation code is all the content I have shared with you. I hope it can give you a reference and I hope you can support Wulin.com more.
