jQuery：保存已选择的选择元素选项

Question

Hey guys I am trying to save the option that a user has selected on my form however I am unsure how I can do this.

I will briefly explain my setup...

I have this form on my home page:

<form class="form-home form-search">
<select class="form-control select-box">
                 <option value="make-any">Make (Any)</option>
                 <?php while($make = $makeFilter->fetch(PDO::FETCH_ASSOC))
                 {
                 echo '
                 <option value="'.$make["Make"].'">'.$make["Make"].'</option>
                 ';
                 } ?>
             </select>
 <button href="used-cars.php">Search</button>
</form>

As you can see it is using PHP/MySQL to show the options available.

Okay so I then have this form on another page however the CSS styling is slightly different and it includes a few different select elements.

So when a user has selected an element on the home page all the button does is href to the used-cars.php which lists all of the results.

How can I make it so that jQuery saves the option the user selected on the home page and loads the used-cars.php with those options selected?

Any examples would be great.

EDITED Example of my second form:

<div class="container con-col-listing">
    <div class="row">
      <div class="col-md-4 col-sm-4">
       <form class="car-finder-container dflt-container">
         <h2 class="h2-finder">Car finder</h2>
         <ul class="toggle-view">
           <li class="li-toggle">
            <h4 class="h4-finder-toggle">Make<span class="glyphicon glyphicon-plus glyph-plus-toggle"></span></h4>
            <div class="panel">
             <select name="make" class="form-control select-box">
                 <option value="make-any">Make (Any)</option>
                 <?php while($make = $makeFilter->fetch(PDO::FETCH_ASSOC)){
                 $selected = $make['make'] == $_GET['make']?'selected="selected"':'';
                 echo '
                 <option value="'.$make["Make"].'">'.$make["Make"].'</option>
                 ';
                 } ?>
             </select>
             <select class="form-control last-select select-box">
                 <option value="model-any">Model (Any)</option>
                 <?php while($model = $modelFilter->fetch(PDO::FETCH_ASSOC))
                 {
                 echo '
                 <option value="'.$model["Model"].'">'.$model["Model"].'</option>
                 ';
                 } ?>
             </select>

            </div>
          </li>
        </ul>
         <button href="#" class="btn btn-block car-search-button btn-lg btn-success"><span class="glyphicon car-search-g glyphicon-search"></span> Search cars 
         </button>
         <h4 class="h4-finder"><a href="#">Try our Smart Search </a><span class="glyphicon info-car-search-g glyphicon-info-sign"></span></h4>
       </form>
      </div>

Answer 1

Easiest way is with a get request:

 <form class="form-home form-search" method="GET" action="used-cars.php">
  <select name="make" class="form-control select-box">
  .....
  <button type="submit">Search</button>
 </form>

and on used-cars.php:

 var_dump($_GET['make']);

EDIT

lets suppose on the form on the first page you have:

  <option value="ford">ford</option>
  <option value="pontiac">pontiac</option>
  <option value="fiat">fiat</option>

when you hit the submit button $_GET['make'] on used-cars.php will be whatever was selected lets say fiat.

so now on used-cars.php you can do this:

 <?php while($make = $makeFilter->fetch(PDO::FETCH_ASSOC)){
    $selected = $make['Make'] == $_GET['make']?'selected="selected"':'';
    echo '
     <option '.$selected.' value="'.$make["Make"].'">'.$make["Make"].'</option>
        ';
  } ?>
