<div id='sampe_1' class='sample'></div>
<div id='sampe_2' class='sample'></div>
<div id='sampe_3' class='sample'></div>

<div id='sampe_100' class='sample'></div>

For expand and collapse To find all div's i am using below two methods

$("div[id^='supplier_']"); I got all 100 div no i loop 1000 times and click event

or

Direct click event with class name

$('.sample').on('click');
