javascript - Binding event to dynamically created element -


in 1 of jsp pages project, create append elements table dynamically, way:

$('.auth').each(function(index, elem) {     $(elem).click(function(){         //do stuff here!         var index = $(elem).data('key'); //this read data-key attribute          var div = "#edit_autorizacao_"+index;         $(div).toggle();          $('#auth-'+index+' tbody.auth').remove();         var newrow = $('<tr>');          $.ajax({             type: "get",             url: "<c:out value="${pagecontext.request.contextpath}/usuario/lista_autorizacao"/>",             cache: false         }).done(function(data){             var obj_auth = jquery.parsejson( data );              for(var item in obj_auth.auth) {                 var checkbox = $('<tr>');                 checkbox.append('<td><input type="checkbox" class="auth_check" data-user="'+index+'" data-key="'+obj_auth.auth[item].id+'" name="'+obj_auth.auth[item].nome+'"></td> <td>'+obj_auth.auth[item].nome+'</td>');                 checkbox.appendto(newrow);             }              $('#auth-'+index).append('<tbody class="auth">');             $('#auth-'+index+' tbody.auth').append(newrow);         });          $.ajax({             type: "get",             url: "<c:out value="${pagecontext.request.contextpath}/usuario/lista_autorizacao_usuario"/>",             cache: false,             data: {id: index}         }).done(function(data){             var obj_auth = jquery.parsejson( data );              for(var item in obj_auth.auth) {                 var checkbox = $('input[name='+obj_auth.auth[item].nome+']');                 $(checkbox).attr("checked","true");             }         });     }); });

now, each 1 of elements:

checkbox.append('<td><input type="checkbox" class="auth_check" data-user="'+index+'" data-key="'+obj_auth.auth[item].id+'" name="'+obj_auth.auth[item].nome+'"></td> <td>'+obj_auth.auth[item].nome+'</td>');

i want bind 'click' event. right now, doing in way:

$('.auth').on('click', '.auth_check', function(event){         var id_auth = $(this).data('key');         var id_user = $(this).data('user');         $.ajax({             type: "get",             url: "<c:out value="${pagecontext.request.contextpath}/usuario/toggle_autorizacao"/>",             cache: false,             data: {id_usuario: id_user, id_autorizacao: id_auth}         }).done(function(data){             if(data == "yes") {                 $("#result_auth").empty().append("ok").hide(3000);             }             else if(data == "not") {                 $("#result_auth").empty().append("erro").hide(3000);             }             else {                 $("#result_auth").empty().append("sem acesso").hide(3000);             }         }); });

but nothing happens when click in element. can point me doing wrong here?

ok, after open topic, find solution problem. happens making binding 2 dynamically created elements; first 1 must static. so, add 'class' atribute 'auth_container' tbody element, , make bind way:

$('.auth_container').on('click', '.auth_check', function(event){

and it's working fine.
