javascript - Update site automatically by calling a function -

-

i building news website using asp.net. want updated automatically pulling new news articles. done calling function downloads updated json string.

how call function every half hour in c#? or should write function in javascript , call every half hour?

you can use timer in c#

protected void page_load(object sender, eventargs e)     {         // create timer         system.timers.timer mytimer = new system.timers.timer();          //call method         mytimer.elapsed += new elapsedeventhandler(mymethod);          //time interval 5 sec         mytimer.interval = 5000;         mytimer.enabled = true;     }  public void mymethod(object source, elapsedeventargs e)     {                     //your code     }

also, can use settimeout function in javascript

settimeout(function() {    //calls click event after time     that.element.click(); }, 5000);

or

use task this

task.factory.startnew(() =>     {         system.threading.thread.sleep(5000);         callmethod();     });
