Question: I need to update given selector continually after the given time intervel. this is my code using javascript.

```
function current_time(){
   var content = document.getElementById('time_div');
   content.innerHTML = '<p> Time is : '+Date()+'</p>';
}

var v = setInterval( 'current_time()', 1000);

```

this is ok. but my question is using jquery can we do that ? I tried this way. it works only one time. how I trigger that event continually after the given time interval(without click event).

```
$(document).ready(function(){
    $('#time_div').click(function(){
        $(this).html('<p>'+Date()+'</p>');
    });
});

```

Answer: 
This should do the trick...

```
$(document).ready(function() {
    var v = setInterval(function() {
        $("#time_div").html("<p>" + Date() + "</p>");
    }, 1000);
});

```

To make your original code a little friendlier to read...

```
var v = setInterval(function() {
   document.getElementById("time_div").innerHTML = "<p>" + Date() + "</p>";
}, 1000);

```
All you need to do is this :-

```
$(document).ready(function(){
    $('#time_div').click(function(){
        $(this).html('<p>'+Date()+'</p>');
    });
});

var v = setInterval( function(){$('#time_div').trigger('click')} , 1000);

```

*setInterval* is a standard JavaScript function, not part of jQuery. You call it with a function to execute and a period in milliseconds. e.g:-

```
setInterval(function() {
//Do something every 1 seconds
}, 1000);

```
