jQuery Get parameter value from URL and check radiobutton PHP

Hi i have a from with few radio buttons to filter my data...I want to check url to make a radio button checked...How i can achieve that ??

Form:

<form method="post">
<div>
    <input id="radio2" type="radio" name="scat" value="ABC" data-href="example.com?link=[value]">

    <label for="radio2">ABC</label>
</div>

</form>

Jquery:

So, are you asking to check the appropriate radio button on page load, when there is a link value in the query string of the URL?

If so, you can do that in two steps: 1. parse the URL. 2. update the correct radio button.

I'm assuming in your example, that you meant to replace [value] with an example like ABC to match the rest of your example. In other words <input id="radio2" type="radio" name="scat" value="ABC" data-href="example.com?link=ABC">.

If so, then your javascript should look like this:

$(document).ready(function() {
    $('input[type=radio]').click(function() {
        window.location=$(this).attr('data-href');
    });
    // parse the url:
    var link = window.location.search.match(/link=(\w+)/)[1];
    if (typeof link !== 'undefined') {
        // update the correct radio button:
        $('input[value="' + link + '"]').prop("checked", true);
    }
});
