I have the following request that lists the students in a table:
jQuery('#presencaExibir').click(function(e){
e.preventDefault();
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
}
});
jQuery.ajax({
url: "/presenca/alunos",
method: 'post',
data: {
sala: jQuery('#sala').val(),
horario: jQuery('#dia-horario').val()
},
success: function(result){
$('#diaChamada').text($('#dia-semana option:selected').text());
$('#listaAlunos').text('');
$.each(result.alunos, function(k, aluno){
$('#listaAlunos').append(
"<tr>" +
"<div class='row'>" +
"<td class='id-aluno'>" + aluno.ID_Aluno + "</td>" +
"<td class='col-6'>" + aluno.Nome + "</td>" +
"<td><i class='material-icons presenca presente'> account_circle </i></td>" +
"</div>" +
"</tr>"
);
});
}});
});
What I need to do is take all values in the "id-student" class td via jQuery and send in another ajax request:
jQuery('#finalizarBtn').click(function(e){
e.preventDefault();
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="_token"]').attr('content')
}
});
jQuery.ajax({
url: "/presenca/finalizar-dia",
method: 'post',
data: {
alunos: $('.id-aluno').text()
},
success: function(result){
console.log(result.alunos);
}});
});
However, when I try to do this, the result I have of $('.id-aluno').text() is
Undefined
How can I get these values inserted in the table dynamically?
If you have several elements with the class
id-alunoyour search$('.id-aluno')will return a list of elements, which does not have the methodtext.– Woss
@Anderson, all jQuery queries return a list, even if you look for a single element. The method
.text()returns theinnerTextof the first element of this list. @Antony, could add your HTML and the return of Ajax to your question, so that it becomes testable?– Andre
@user140828 Not so. The
$('.id-aluno').text()will return the text of all elements with the class.id-aluno, not just the first.– Sam
Antony, I think you’re making a mistake. The
$('.id-aluno').text()will never resumeundefined, even if there is no element with that class.– Sam
@Sam thanks for watching me. In fact I was confusing things myself and Undefined was coming from a wrong treatment I was doing within PHP. I managed to settle here.
