Я пытаюсь добавить строки в шаблон django, используя JavaScript, но он не работает так, как должен:
HTML
<html>
<head>
<title>gffdfdf</title>
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">

<script src="/static/jquery.formset.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<form id="myForm" action="" method="post" class="">
{% csrf_token %}
<h2> Team</h2>
{% for field in form %}
{{ field.errors }}
{{ field.label_tag }} : {{ field }}
{% endfor %}
{{ form.player.management_form }}
<h3> Product Instance(s)</h3>
<table id="table-product" class="table">
<thead>
<tr>
<th>player name</th>
<th>highest score</th>
<th>age</th>
</tr>
</thead>
{% for player in form.player %}
<tbody class="player-instances">
<tr>
<td>{{ player.pname }}</td>
<td>{{ player.hscore }}</td>
<td>{{ player.age }}</td>
<td> <input id="input_add" type="button" name="add" value=" Add More " class="tr_clone_add btn data_input"> </td>
</tr>
</tbody>
{% endfor %}
</table>
<button type="submit" class="btn btn-primary">save</button>
</form>
</div>
<script>
var i = 1;
$("#input_add").click(function() {
$("tbody tr:first").clone().find(".data_input").each(function() {
if ($(this).attr('class')== 'tr_clone_add btn data_input'){
$(this).attr({
'id': function(_, id) { return "remove_button" },
'name': function(_, name) { return "name_remove" +i },
'value': 'Remove'
}).on("click", function(){
var a = $(this).parent();
var b= a.parent();
i=i-1
$('#id_form-TOTAL_FORMS').val(i);
b.remove();
$('.player-instances tr').each(function(index, value){
$(this).find('.data_input').each(function(){
$(this).attr({
'id': function (_, id) {
var idData= id;
var splitV= String(idData).split('-');
var fData= splitV[0];
var tData= splitV[2];
return fData+ "-" +index + "-" + tData
},
'name': function (_, name) {
var nameData= name;
var splitV= String(nameData).split('-');
var fData= splitV[0];
var tData= splitV[2];
return fData+ "-" +index + "-" + tData
}
});
})
})
})
}
else{
$(this).attr({
'id': function (_, id) {
var idData= id;
var splitV= String(idData).split('-');
var fData= splitV[0];
var tData= splitV[2];
return fData+ "-" +i + "-" + tData
},
'name': function (_, name) {
var nameData= name;
var splitV= String(nameData).split('-');
var fData= splitV[0];
var tData= splitV[2];
return fData+ "-" +i + "-" + tData
}
});
}
}).end().appendTo("tbody");
$('#id_form-TOTAL_FORMS').val(1+i);
i++;
});
</script>
</body>
</html>
приведенный выше код создает форму с тремя полями, то есть player name, highest score и age с кнопкой add more
, но согласно this должно получиться следующее:
<!-- First row of the table -->
<tr>
<td><input type="text" name="form-0-name" id="id_form-0-name" /></td>
<td>
<input type="number" name="form-0-quantity" id="id_form-0-quantity" />
</td>
<td><input type="number" name="form-0-price" id="id_form-0-price" /></td>
<td>
<input
id="input_add"
type="button"
name="add"
value=" Add More "
class="tr_clone_add btn data_input"
/>
</td>
</tr>
<!-- Second row of the table -->
<tr>
<td><input type="text" name="form-1-name" id="id_form-1-name" /></td>
<td>
<input type="number" name="form-1-quantity" id="id_form-1-quantity" />
</td>
<td><input type="number" name="form-1-price" id="id_form-1-price" /></td>
<td>
<input
id="remove_button"
type="button"
name="remove_button1"
value=" Remove "
class="tr_clone_add btn data_input"
/>
</td>
</tr>
<!-- more inline formset are going to rendered here -->
Но когда я создаю еще одну строку в форме, она создает еще одну строку с такими же name и id.
См .:
<tbody class="player-instances">
<tr>
<td><input type="text" name="form-0-pname" id="id_form-0-pname"></td>
<td><input type="number" name="form-0-hscore" id="id_form-0-hscore"></td>
<td><input type="number" name="form-0-age" id="id_form-0-age"></td>
<td> <input id="input_add-0-undefined" type="button" name="add-0-undefined" value=" Add More " class="tr_clone_add btn data_input"> </td>
</tr>
<tr>
<td><input type="text" name="form-0-pname" id="id_form-0-pname"></td>
<td><input type="number" name="form-0-hscore" id="id_form-0-hscore"></td>
<td><input type="number" name="form-0-age" id="id_form-0-age"></td>
<td> <input id="remove_button-1-undefined" type="button" name="name_remove1-1-undefined" value="Remove" class="tr_clone_add btn data_input"> </td>
</tr></tbody>
Почему это не добавляет строка с обновленными name и id?
Обновление:
