[Solved] How to create search tab and open the .txt file? [closed]

for this you have to save the path of the text file in the value of the option in select and may be you can do this dynamically
as below

  <select id="myselect">
    <option value="url_to_text_file_on_server">link</option>
</select>

then to open the text file you can use the window.location of javascript for opening the html file as below

$("#myselect").change(function(){
  window.location = $( "#myselect option:selected" ).val();
});

UPDATE

To add a select widget to your page, start with a standard select element populated with a set of option elements. Set the for attribute of the label to match the ID of the select so they are semantically associated. Wrap them in a div with the data-role=”fieldcontain” attribute to help visually group it in a longer form.

for jquery mobile
html part

<div data-role="fieldcontain">
    <label for="myselect" class="select">Choose shipping method:</label>
        <select name="myselect" id="myselect">
          <option value="url_to_text_file_on_server">link</option>
        </select>
</div>

script should go in document ready function in the botton

$(document).ready(function(){
 $("#myselect").on("change",function(){
  window.location = $( "#myselect option:selected" ).val();
  });
});
