How to make jQuery form submission not refresh the page but add the content - AJAX like? -


in $('#my_form').submit(function() have code should add more information on selected song my_form form. able change content of info_table on each form submission (if different song marked). how can ? if leave return false; page won't reload anymore.

<!doctype html> <html> <body> <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" ></script>  <form id="my_form"> <table border='2' id="my_table"></table> <input type="submit" value="show song info" id="submit_button"> </form> <table border='2' id="info_table"></table>  <script> var my_xml; $(document).ready(function()   {      $.get("songs_2.xml", function(d){         my_xml = d;         //$('body').append("<table border='2'>");         var html = "";         var = 0;          $(d).find('song').each(function(){             var $song = $(this);             var title = $song.find('title').text();             var artist = $song.find('artist').text();             var cover = $song.find('cover').text();             var id = $song.find("id").text();              html += "<tr><td>"+id+"</td><td width='120'><b>" + artist + " </b></td><td width='150'> " + title + "</td><td>";             html += "<img src='" + cover + "' height='50' width='50'/></td><td> <input type='radio' name='which' value='"+id+"'></td></tr>" ;             $('#my_table').append($(html));             html = ""             i++;         });     }); });  $('#my_form').submit(function() {     var = $("#my_form input[type='radio']:checked").val();     $.get("songs_2.xml", function(d){         my_xml = d;         //$('body').append("<table border='2'>");         var html = "";         var = 0;          $(d).find('song').each(function(){             var $song = $(this);             var title = $song.find('title').text();             var artist = $song.find('artist').text();             var cover = $song.find('cover').text();             var id = $song.find("id").text();            $('#info_table').html("<tr><td>" + alotofinfo + "</td></tr>");         });     });     return false; }); </script> </body> </html>

you need prevent default behavior of form submit , modified code consider performance of calling jquery.html in each loop will add 1 row 

$('#my_form').submit(function(e) {     e.preventdefault();      var = $("#my_form input[type='radio']:checked").val();     $.get("songs_2.xml", function(d){         my_xml = d;         var html = "";          $(d).find('song').each(function(){             var $song = $(this);             var title = $song.find('title').text();             var artist = $song.find('artist').text();             var cover = $song.find('cover').text();             var id = $song.find("id").text();                html = html+"<tr><td>" + alotofinfo + "</td></tr>";           });         $('#info_table').append(html);      }); });

i hope can :)
