如何在购物车中获取和提交所选项目？
以下是我的演示，
有两个问题：
1，目前，我只能手动获取一个项目，如何获取所有选定的项目？
2，如果没有选择任何内容，我想要按钮＆＃34;提交＆＃34;要禁用。

每个复选框都有相同的名称，所以发生的是：
domainList = on
domainList = on
domainList = on
domainList = on
只有最后一个被发送。您需要在名称中添加[]以使其成为数组。
domainList[] = on
domainList[] = on
domainList[] = on
domainList[] = on
这将为Laravel控制器提供一个阵列，而不仅仅是一个阵列。
示例：
<input type="checkbox" name="domainList[]" id="goods_102" class="checkboxSelection">
但是，您正在使用这些是复选框。它们的默认值为＆＃34; on＆＃34;并且仅在选中时显示在表单数据中。您绝对应该向它添加value来表示项目的数据库行。
例如：
<input type="checkbox" name="domainList[]" id="goods_102" class="checkboxSelection" value="stackoverflow.com" >
那会返回一个字符串数组
domainList[] = stackoverflow.com
domainList[] = stackexchange.com
domainList[] = serverfault.com

使用下面的第二个问题更新您的脚本：
$(document).ready(function(){
if($(".table tr input[type='checkbox']:checked").length > 0)
{
$('#submit').attr("disabled",false);
}
else
{
$('#submit').attr("disabled","disabled");
}
//Select all
$("#selectAll").change(function () {
if ($(this).is(":checked")) {
$(".checkboxSelection").each(function () {
$(this).prop('checked', true);
});
$('#submit').attr("disabled",false);
}
else {
$(".checkboxSelection").each(function () {
$(this).prop('checked', false);
});
$('#submit').attr("disabled","disabled");
}
});
$(".checkboxSelection").change(function () {
var allSelected = true;
$(".checkboxSelection").each(function () {
if (!$(this).is(":checked")) {
$("#selectAll").prop('checked', false);
allSelected = false;
}
});
if (allSelected)
{
$("#selectAll").prop('checked', true);
}
if($(".table tr input[type='checkbox']:checked").length < 1)
{
$('#submit').attr("disabled","disabled");
}
else
{
$('#submit').attr("disabled",false);
}
});
