    Ned help generating simple Javascript application to refine searches

    Hello friends and programmers ..

    I am trying to have a button that instantly refines my searches

    Something like

    Onclick("SELECT * FROM TBL WHERE Description LIKE $value")

    Is this something a newbie could pull of or does it require more than just working knowledge of PHP, MYSQL, and Javascript

    I have looked through Google, but have not found a good resource to base my script on.

    Thanks

    this is not just a single button. you need a php file having the function which makes the sql query and outputs the result. this result is recieved by javascript and placed into the page.

    Re:

    Does that method work with Pagination as well?

    My script looks something like

    <script>
    var form = document.getElementById('keywordForm');
    form.addEventListener('submit',function(e) {
    var search = form.keyword.value;
    var xhr = new XMLHttpRequest();
    xhr.open("GET","keywordsearch.php?search="+search,true);
    xhr.send();
    xhr.onreadystatechange = function() {
    if(xhr.readyState == 4 && xhr.status == 200) {
    var response = xhr.response;
    }
    };
    e.preventDefault();
    });

    This is a search - but it's not working

    Is there a mistake in my code?

    });
    $("#res").click();
    });
    </script>

    '
    ;
    }

    function 
    dosearch(){
    $output='';
    if(isset(
    $_GET['keyword'])&&!empty($_GET['keyword'])){
    //here go your mysql query functions
    $output='<h3>Query results for " <span class="r">'.$_GET['keyword'].'</span> "</h3>';
    }
    else{

    echo 
    $output;
    }

    $mode=(!empty($_GET['mode']))?$_GET['mode']:$_POST['mode'];
    switch(
    $mode){
    case 
    'ds':dosearch();break;
    default:
    markup();
