javascript - Adding multiple GET Parameters to URL using window.location.assign from checkboxes - Stack Overflow

I'm trying to use JavaScript to add parameters to the current URL in order to filter WordPress posts. Example: /?rooms=1,2&bath=1&yard=yes

I have successfully done this with one of the parameters, but I'm failing in understanding how to add on multiple parameters. What is the proper way of getting this one?

Also, is using window.location.assign(), the proper way for adding the parameters to the URL? Is using AJAX better/safer?

Below is my code

HTML

<div id="filter-rooms">
       <ul>
           <li>
               <input type="checkbox" value="1" id="rooms" />1 Room</li>
           <li>
               <input type="checkbox" value="2" id="rooms" />2 Rooms</li>
           <li>
               <input type="checkbox" value="3" id="rooms" />3 Rooms</li>
           <li>
               <input type="checkbox" value="4" id="rooms" />4 Rooms</li>
      </ul>
</div>

<div id="filter-bath">
    <ul>
        <li>
            <input type="checkbox" value="1" id="bath" />1 Bathrooms</li>
        <li>
            <input type="checkbox" value="2" id="bath" />2 Bathrooms</li>
        <li>
            <input type="checkbox" value="3" id="bath" />3 Bathrooms</li>
    </ul>
</div>

<div id="filter-yard">
    <ul>
        <li>
            <input type="radio" name="yard" value="yes" id="yard" />Yes</li>
        <li>
            <input type="radio" name="yard" value="no" id="yard" />No</li>
    </ul>
</div>

JavaScript

$('#filter-rooms').on('change', 'input[type="checkbox"]', function () {

    var $ul = $(this).closest('ul'),
        vals = [];

    $ul.find('input:checked').each(function () {

        vals.push($(this).val());

    });

    vals = vals.join(",");

    window.location.assign('?rooms=' + vals);

});

Now, in the JavaScript displayed above, I managed to get the rooms parameter successfully working, but when I duplicate this for the other parameters, it replaces the URL with the rooms parameter instead of adding it on to the end of the URL like so - &bath=1&yard=yes

jsFiddle: / (Note: window.location.assign() is missing because jsFiddle doesn't allow it.)

Any advice on this would be greatly appreciated.

First, do not use the same id on multiple elements. See Why is it a bad thing to have multiple HTML elements with the same id attribute?

Your problem is with this line

 window.location.assign('?rooms=' + vals);

You need to dynamically update the query string.

Using this method

function updateQueryStringParameter(uri, key, value) {
  var re = new RegExp("([?&])" + key + "=.*?(&|$)", "i");
  var separator = uri.indexOf('?') !== -1 ? "&" : "?";
  if (uri.match(re)) {
    return uri.replace(re, '$1' + key + "=" + value + '$2');
  }
  else {
    return uri + separator + key + "=" + value;
  }
}

from add or update query string parameter

and custom attributes like

<ul data-type="rooms">

you can do

window.location.href = updateQueryStringParameter(window.location.href, $ul.attr('data-type'), vals);

instead of

window.location.assign('?rooms=' + vals);

Try this : define variables to store rooms, bath and yard selected values and create url accordingly in each change handler of inputs.

roomVal = '';
bathVal = '';
yardVal = '';

$('#filter-rooms').on('change', 'input[type="checkbox"]', function () {
     roomVal = $(this).closest('ul').find('input[type="checkbox"]:checked').map(function(i,v){
        return $(this).val();
    }).get();

    window.location.assign('?rooms=' + roomVal + '&bath='+bathVal+"&yard="+yardVal);
});

$('#filter-bath').on('change', 'input[type="checkbox"]', function () {
     bathVal = $(this).closest('ul').find('input[type="checkbox"]:checked').map(function(i,v){
        return $(this).val();
    }).get();

    window.location.assign('?rooms=' + roomVal + '&bath='+bathVal+"&yard="+yardVal);
});

$('#filter-yard').on('change', 'input[type="radio"]', function () {
     yardVal = $(this).closest('ul').find('input[type="radio"]:checked').map(function(i,v){
        return $(this).val();
    }).get();

    window.location.assign('?rooms=' + roomVal + '&bath='+bathVal+"&yard="+yardVal);
});

JSFiddle Demo

You can simply do it with window.location.href If you have any value stored in a variable, you can use the + symbol to concatenate the value.

var somedata = somedata;

window.location.href = "http://www.yourwebsite.?data1=somedata&data2="+somedata;
