How to get query string from URL using Javascript or jQuery to populate select values?
<p>I have 3 select or option drop lists that based on what the users selects needs to populate or select the select value of the drop list based on the query string. So I guess I need help getting the URL and query string and find out if it contains any of what the user selected to populate the select value. </p>

<p>Right now my select values are not persistent when a user selects them, then submits a search.   How would I keep them persistent with Javascript or jQuery?
My other issue is that the user can search All options, I have that working but there is a Checkbox that places a value and the value is read to search everything. How would I, on the first page load, have that check box checked and the query string of '?search=%20%20%200' to populate the URL query string.  Thanks in advance.</p>

<p>Here is my current JS:</p>

<pre><code>var resourceGradeId;
var resourceContentId;
var resourceProgramTypeId;
var resourceSearchAll;

$(document).ready(function() {

var searchAll = '&lt;strong&gt;' + "All" + '&lt;/strong&gt;';
$('#xsltsearch_summary .dmnsSearchResultNumber:contains("0")').replaceWith(searchAll); 

$("#resourceSelect").click(function (event) { 
resourceGradeId = $('#teachersResourceSearchGrade').val();
 resourceContentId = $('#teachersResourceSearchContent').val();
 resourceProgramTypeId = $('#teachersResourceSearchProgramType').val(); 
resourceSearchAll = $('#teachersResourceSearchAll').val();
window.location.href = '/teachers/classroom-resources?search=' + resourceGradeId + ' ' + resourceContentId + ' ' + resourceProgramTypeId + ' ' + resourceSearchAll;
    });

$("select option").attr('disabled', false);

    $(":checkbox").click(function(event) { 
    //reset values
    if($(":checkbox").is(":checked")){
          $("#teachersResourceSearchGrade").val('');
          $("#teachersResourceSearchContent").val('');
          $("#teachersresourceProgramTypeId").val('');
          $("#teachersResourceSearchAll").val('0');
          $("select").attr('disabled', true);
        }
    else
        { 
          $("#teachersResourceSearchAll").val('');
          $("select").attr('disabled', false);
          $("select option").attr('disabled', false);
          }
     });
});
</code></pre>
