JavaScript Implementation page timed refresh (timer, meta) _javascript tips

Next go to the topic-the way to refresh the page regularly:

1. See timing, it is easy to think of JS timer:

The first method
//Because we already have a timer, so just add a word to refresh the page in the timer test to
function test () {
h1.style.color = "Red";
H1.innertext = "I have changed";
History.go (0);//Can be replaced by any one of the previous blog methods.
}
SetInterval (test, 1000);

2. Use Meta to set:

<!--the second method-->
<!--automatic refresh, content indicates the refresh interval, in seconds s, the following code indicates that the page is refreshed once every three seconds-->
<meta http-equiv= " Refresh "content=" 3 >
<!--the third method-->
<!--This method to achieve page refresh a bit opportunistic, this label function is a timed jump, the content of the first parameter to indicate the interval time, The unit is seconds, the second parameter represents the destination URL, but if the second parameter is set to #, the page refresh is implemented. -->
<meta http-equiv= "Refresh" content= "3;url=#" >
