How to add var javascript value into id name?

Question

How to add var javascript value into id name ?

I have $i = 5; and var i = 2;

How to concatenate php var $i with javascript var i ?

I tried like this but not work.

$('#test<?PHP echo $i; ?>'+i).live('click', function() { 
do something
});

and

$('#test<?PHP echo $i; ?>'+i+'').live('click', function() { 
do something
});

How can i do that ?

`live()` was deprecated in favour of `on()` years ago, you should update your jQuery. — Quentin, Mar 31 '16 at 11:54
Depending when this JS code runs, [this question](http://stackoverflow.com/questions/14028959/why-does-jquery-or-a-dom-method-such-as-getelementbyid-not-find-the-element) _might_ be relevant. — James Thorpe, Mar 31 '16 at 11:54
Any time you are generating ids in a loop for JS, you should probably be using a class instead. — Quentin, Mar 31 '16 at 11:55

var phpi = '<?PHP echo $i; ?>';
$('#test' + phpi + i).live('click', function() { 
    //do something
});

or if you want PHP $i + JS i for exmaple (3 + 2 = 5)

var phpi = <?PHP echo $i; ?>; // no quotes here as we need number
$('#test' + (phpi + i)).live('click', function() { 
    //do something
});

PHP echo makes some space so that might hamper the selector use it like this
