You can do it by either renaming you js file to php and using this link in script tag src (as pointed in other answers)

While this may seems a good and easy way there is many reason not to do this.

• Caching (your generated script will not be cached, this may be changed but require additional work)
• Memory consumption (every request to this generated js file will require php)

You can simply changed to something like this to get it done (in a better way, IMO):

Than content of your js became something like this:

$(document).ready(function(){
  // I assume that not using search_city in your sample code
  // and some syntax errors, is just by mistake...
  $('#update').click(function(){
  var tableVal={search_city:Settings.search_city};
  $.post(Settings.base_url+'/project_detail/pub',
    {'tableVal':tableVal},
    function(message){
      console.log(message);
    })
  })
})
