Bootstrap Select - Set selected value by text

Question

How can I change the drop down if I only know the text and not the value?

Here is my select -

 <select id="app_id" class="selectpicker">
       <option value="">--Select--</option>
       <option value="1">Application 1</option>
       <option value="2">Application 2</option>
 </select>

You can use jquery filter() and prop() like below

jQuery("#app_id option").filter(function(){
    return $.trim($(this).text()) ==  'Application 2'
}).prop('selected', true);
