<div class="wrap">
<div class="test"></div>
<div class="test"></div>
<div class="test"></div>
</div>
I want to add id to each .test
becomes
<div class="test" id="test-1"></div>
<div class="test" id="test-2"></div>
<div class="test" id="test-3"></div>
how can this be achieved?
you can use js jquery
$(".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)
}
