ขอแนวคิดการนำ keyword ไป search คล้ายๆของ google โดยใช้ javascript และ jQuery ครับ

$('input[name="btn"]').click(function(){
    var searchterm = $('input[name="search"]').val();
    var exp = new RegExp(searchterm,"i");
    if (searchterm.length < 3) {
        alert("Enter at least three characters");
    }else{
        $.ajax({
            type: "GET",
            url: "posiding.xml",
            dataType: "xml",
            success: function(xml) {
                results = new Array;
                $('#result').html("");
                $('#count').html("");
                count = 0;
                $(xml).find('book').each(function(){
                    id = $(this).attr('id');
                    title = $(this).find('title').text();
                    author = $(this).find('author').text();
                    keyword = $(this).find('keyword').text();
                    if ( title.match(exp) != null || author.match(exp) != null || keyword.match(exp) != null) {
                        count++;
                        $('<div class="book" id="link_'+id+'"></div>').html("<p><b>"+title+"</b><br>"+author+"</p>").appendTo('#result');
                    }
                });
                $('#count').html(searchterm+": เจอทั้งหมด "+ count +" บทความ");
            }
        });
    }
});
