JS implementation can automatically refresh the time-date code instance:
can automatically refresh the time date effect in a lot of pages are in use, because can make the page more dynamic, but also more user-friendly, users can view the time of the page in real-time, the following is a code example to explain how to achieve this effect.
The code is as follows:
<!DOCTYPE HTML> <HTML> <Head> <MetaCharSet= "Utf-8"> <Metaname= "Author"content= "http://www.softwhy.com/" /> <title>Ant Tribe</title> <Scripttype= "Text/javascript"src= "Mytest/jquery/jquery-1.8.3.js"></Script><Scripttype= "Text/javascript"> functionGetTime () {varodate=NewDate (); varDate=odate.tolocaledatestring (); varhours=odate.gethours (); varminutes=odate.getminutes (); varseconds=odate.getseconds (); $("#showDate"). HTML (Date+" "+(Hours>9?Hours:"0"+hours)+":" +(Minutes>9?minutes:"0"+minutes)+":" +(Seconds>9?seconds:"0"+seconds));} $(function() {setinterval ("getTime ();", +);}) </Script> </Head> <Body> <DivID= "Showdate"></Div></Body> </HTML>
The above code realizes the automatic refresh effect of the implementation time date, and the following describes its implementation process.
A. Code Comment:
1.function getTime () {}, this function can get the current time date.
2.var odate=new Date (), which creates the current time-of-day object.
3.var date=odate.tolocaledatestring (), you can get the local month day.
4.var hours=odate.gethours (), gets the hour.
5.var minutes=odate.getminutes (), get minutes.
6.var seconds=odate.getseconds (), gets the seconds.
7.$ ("#showDate"). HTML (date+ "" + (Hours>9?hours: "0" +hours) + ":" + (minutes>9?minutes: "0" +minutes) + ":" + (seconds >9?seconds: "0" +seconds), writes the current time date to the specified element, which is, of course, the Div, which is used to implement the ternary operator in order to achieve the front plus 0 when the hour, minute, and second are single digits.
8.$ (function () {setinterval ("getTime ();", 1000);}) executes the specified functions once per second.
Two. Related reading:
1. For a Time object, refer to the ECMAScript Date Object section.
2. Ternary operators can refer to the chapter on the use of ternary operators.
The 3.setInterval () function can be found in the setinterval () Function usage section.
