jQuery Forum

Hi,
please I have this code

1. <optgroup label="Service Group">
2.       <option class="dropdown-item" onclick="testFunction()">service 1</option>
3. </optgroup>

and when I click on this option from desktop, testFunction runs perfectly, but when I click on it from my mobile browser nothing happens.

1. function testFunction() {
       jQuery('#test.recommend_link').show();
       jQuery('.recommend_link').not('#test').hide();
   }

How could I solve this problem??
