javascript - jQuery Code won't connect to search form -

-

this question pertains this question/post. have search form requires: a: pull user input search form our backend can provide user relevant search results. b: need able insert default input either, or both, search fields enhance user search experience. should replace placeholder values.

i have tried following code in main.js file (linked testpage.html):

$(document).ready(function(){   $("#btn-search").click(function(e){     e.preventdefault();     var x = $("#keyword").val("nurse");     var y = $("#location").val();     $("#keyword").attr("value", x);     $("#location").attr("value", y);   }); });

i have tried following:

$(document).ready(function(){   $("#btn-search").click(function(e){     e.preventdefault();     $("#keyword").val(nurse);     $("#location").val();   }); });

do know why wouldn't work? tried put in body of page:

<script>   $("#btn-search").click(function(e){     e.preventdefault();     $("#keyword").val(nurse);     $("#location").val();   }); </script>

here's html form:

<form class="form-inline no-margin center-block" action="http://www.somewebsite.com/unknown" method="post" role="form">                   <div class="row">                     <center>                     <fieldset>                        <!-- search input-->                       <div class="form-group center-block">                         <div class="col-sm-4">                           <label class="sr-only" for="keyword">from:</label>                           <input id="keyword" name="keyword" type="search" placeholder="keyword" value="" class="form-control input-lg">                          </div>                       </div>                        <!-- search input-->                       <div class="form-group center-block">                         <div class="col-sm-4">                           <label class="sr-only" for="location">from:</label>                           <input id="location" name="location" type="search" placeholder="city, state, or zip code" class="form-control input-lg">                          </div>                       </div>                        <input type="hidden" name="unknown" value="unknown">                        <!-- button -->                       <div class="form-group center-block">                         <div class="col-sm-2">                           <button type="submit" id="btn-search" name="btn-search" class="btn btn-primary btn-lg btn-tusaj">search</button>                         </div>                       </div>                     </fieldset>                   </div>                 </form> 

$(document).ready(function(){   $("#btn-search").click(function(e){     e.preventdefault();     $("#keyword").val("nurse");     $("#location").val("");   }); });

val() requires string. using string should solve problem.
