you can use js jquery

Javascript

$(".wrap .test").each(function(i) {
    $(this).attr('id', 'test-' + (i + 1))
})

change it directly by JS. 

var eles = document.querySelectorAll('.wrap .test');

eles.forEach(function(v, i) {
    v.setAttribute('id', 'test-' + (i + 1))
})
var test=$(".test")
for(var i=0;i<test.length;iPP){
    test[i].id='test-' + (i + 1)
}
