I've to trigger an alert when button #1 is clicked and then after the button 2# is clicked
if button 1# is clicked and immediately user is clicked on another button button x# then alert should not be trigger.
I've to track those 2 clicks that are one after the other so that i'll embed the js script in the google tag manager
This example will trigger an alert when Button 3 is clicked after Button 1.
var Last;
function getLast(t){
if(Last=='btn1'&&t.id=='btn3')alert('btn1 then btn3')
Last=t.id;
};<button id='btn1' onclick='getLast(this);'>Button 1</button>
<button id='btn2' onclick='getLast(this);'>Button 2</button>
<button id='btn3' onclick='getLast(this);'>Button 3</button>EDIT: with a timeout (like sugsested on comments), sequence must be done before 2 sec.
var Last,time;
function getLast(t){
if(Last=='btn1'&&t.id=='btn3')alert('btn1 then btn3');
Last=t.id;
clearTimeout(time);
time=setTimeout(function(){Last='';}, 2000);
};<button id='btn1' onclick='getLast(this);'>Button 1</button>
<button id='btn2' onclick='getLast(this);'>Button 2</button>
<button id='btn3' onclick='getLast(this);'>Button 3</button>
