How to add .delay to .click on .each iteration (jquery)

Question

So, I want to put delay on this JavaScript code.

$(function(){ 
     $('.clickThis').each(function(){ 
         $(this).click();
     }); 
});

I tried this

$(function(){ 
     $('.clickThis').each(function(){
         $(this).click().delay(5000); 
     }); 
});

above script doesnt work .

Is there any alternative?

I've tried Google it but I still couldn't figure it out, because I have little knowledge in JavaScript.

Answer 1

This will do it:

$(function(){ 
    $('.clickThis').each(function(i, that){ 
        setTimeout(function(){
            $(that).click();
        }, 5000*i );
    }); 
});

Answer 2

Here's a version using a recursive setTimeout loop.

$(function() {
    var click = $('.clickThis').toArray();

    (function next() {
        $(click.shift()).click();   // take (and click) the first entry
        if (click.length) {         // and if there's more, do it again (later)
            setTimeout(next, 5000);
        }
    })();
});

The advantage of this pattern over setTimeout(..., 5000 * i) or a setInterval call is that only a single timer event is ever queued at once.

In general, repeated calls to setTimeout are better than a single call to setInterval for a few reasons:

1. setInterval calls can queue up multiple events even if the browser isn't active, which then all fire as quickly as possibly when the browser becomes active again. Calling setTimeout recursively guarantees that the minimum time interval between events is honoured.
2. With setInterval you have to remember the timer handle so you can clear it

Answer 3

Try to use this:

$(function () {
    var items=$('.clickThis');
    var length=items.length;
    var i=0;
    var clickInterval=setInterval(function(){
        items.eq(i).click();
        i++;
        if(i==length)
            clearInterval(clickInterval);
    }, 5000);
});

您需要编写一个异步的setTimeout循环，以获取更多信息http://www.erichynds.com/javascript/a-recursive-settimeout-pattern/

Answer 5

var $clickthis=$(".clickthis");
var i= -1;
var delayed = setInterval(function(){
 if (++i < $clickthis.length) $clickthis.eq(i).trigger("click");
 else clearInterval(delayed);
}, 5000);

Answer 6

I am not sure but I think that setTimeout function should do the trick. See here https://developer.mozilla.org/en-US/docs/DOM/window.setTimeout

Answer 7

Try

$(function(){ 
     $('.clickThis').each(function(_,i){ 
        var me=$(this);
        setTimeout(function(){me.click()},5000*i);
     ); 
});
