我有一个带有 3 个复选框数组的表单 - 鹰嘴豆泥 []、蛋黄酱 []、果酱 []。在下面的jQuery函数中，当检查所需数量的复选框时，将禁用其余的复选框（当前可行）。

问题：当它们被选中时，我也试图将选中的复选框值转换为文本字段值，hummus1、hummus2、mayo1、jam1 - （这些文本字段将更改为隐藏字段以便在实时发布时发布）。2 个hummus 函数不起作用，mayo 和 jam 函数只返回数组的第一个复选框值，无论是否选中。

非常感谢这里的任何帮助。

jQuery(function one(){
var max = 2;
var checkboxes = $('input[type="checkbox"][name="hummus[]"]');

checkboxes.change(function(){
var current = checkboxes.filter(':checked').length;
checkboxes.filter(':not(:checked)').prop('disabled', current >= max);

// Trying to insert the 2 checked hummus values from the hummus array into text fields
$('input[type="text"][name="hummus1"]').val($('input[type="checkbox"][name="hummus[0]"]').val());
$('input[type="text"][name="hummus2"]').val($('input[type="checkbox"][name="hummus[1]"]').val());
});
});

jQuery(function two(){
var max = 1;
var checkboxes = $('input[type="checkbox"][name="mayo[]"]');

checkboxes.change(function(){
var current = checkboxes.filter(':checked').length;
checkboxes.filter(':not(:checked)').prop('disabled', current >= max);

// Trying to insert the single checked mayo value into the mayo1 text field
$('input[type="text"][name="mayo1"]').val($('input[type="checkbox"][name="mayo[]"]').val());
});
});

jQuery(function three(){
var max = 1;
var checkboxes = $('input[type="checkbox"][name="jam[]"]');

checkboxes.change(function(){
var current = checkboxes.filter(':checked').length;
checkboxes.filter(':not(:checked)').prop('disabled', current >= max);

// Trying to insert the single checked jam value into the jam1 text field
$('input[type="text"][name="jam1"]').val($('input[type="checkbox"][name="jam[]"]').val());
});
});

jQuery(function uncheck() {
// Uncheck all checkboxes on page load    
$(':checkbox:checked').removeAttr('checked');
})

查看我所做的更改，看看您是否了解发生了什么。这段代码在我的演示中对我来说很好。您不需要将每个更改功能包装在其自己的功能中，您只需在文档准备功能中设置每个操作。
