HTML动态添加文件输入不起作用
Js *_*Lim 6 html javascript jquery clone file
例如，我有一个名为 students
我允许用户动态添加学生
每个学生都有字段Name , Points , & Image
该名称与点工作。添加图像字段时出现问题
请参阅上面的附件，当我尝试从第 2 个学生中选择文件时，图像值会转到第 1 个学生。
<label for="student-image-1">指向第一个学生
<label for="student-image-2">指向第二个学生
并且文件输入的id是正确的。
注意：我使用jQuery.clone来复制div
知道为什么我选择第二个输入会填充到第一个？
源代码
$('#student-add-more').click(function(e) {
e.preventDefault();
var count = $('div[id^=student-row-]').length;
var last = $('div[id^=student-row-]').last();
var $clone = last.clone(true);
var next_id = count + 1;
$clone.attr('id', 'student-row-' + next_id);
$clone.find('.image-label')
.attr('for', 'student-image-' + next_id)
;
var fileinput = $clone.find('.filestyle')
.attr('id', 'student-image-' + next_id)
.attr('name', 'students_image['+count+']')
;
fileinput.wrap('<form>').closest('form').get(0).reset();
fileinput.unwrap();
$clone.find('.bootstrap-filestyle > label.btn')
.attr('for', 'student-image-' + next_id)
;
$clone.find('.bootstrap-filestyle > input').val('');
var delete_button = $clone.find('.btn-danger')
.attr('data-url', 'student-row-' + next_id)
.attr('href','#deleteModal')
.attr('class', 'btn btn-danger btn-sm btn-delete')
;
delete_button.closest('.form-group').removeAttr('style');
$clone.show().insertAfter(last);
});

终于解决了这个问题，我刚刚意识到文件输入使用的是Bootstrap Filestyle。
// file
var file_container = $clone.find('.filestyle').parent();
file_container.empty();
var fileinput = $('<input>').addClass('filestyle').attr({
id: 'student-image-'+next_id,
name: 'students_image['+count+']',
type: 'file',
});
file_container.append(fileinput);
fileinput.filestyle({
icon: 'false',
classButton: 'btn btn-default',
classInput: 'form-control inline input-s',
});
var file_label_container = file_container.prev();
var new_label = $('<label>').addClass('image-label').attr('for', 'student-image-'+next_id).text(file_label_container.find('label').text());
file_label_container.find('label').remove();
file_label_container.prepend(new_label);
我删除了原始输入，并重新创建了一个普通输入，然后使用 filestyle 来设置文件输入的样式并附加到容器中。以及左侧的标签。
