我的逻辑（显然）已关闭，但这就是我所拥有的......
当购买请求获得批准后，它会进入我们的“购买者”列表，这些人开车进城去获取物品（我住在阿拉斯加乡村，所以这是一个大问题）。无论购买请求如何，所有项目都会被转储到每个供应商的foreach循环中。换句话说，可能有10个购买请求，但所有Home Depot项目都在Home Depot表中。
我希望有一个盒子可以检查每个供应商“将所有商品标记为已购买”，因此当有人离开商店时，他们只能标记他们获得了所有Home Depot商品。
这是我的问题。 它并不总是有效。 2.当它工作时，你只能获得1次射击。单击它后，您必须刷新页面才能再次触发该功能。有人能指出我正确的方向吗？

我不被评论。我通过循环中的复选框列表实现了类似的.Jquery。像这样：
$(checkboxlist).each(function (){
$(this).prop('checked',true)
});

您可以采取以下措施：
$(function() {
// first select all
$('#first .select-all').click(function() {
if ($('#first .select-all:checked').length == 0) {
$('#first input[type="checkbox"].option').prop('checked', false);
}
else
{
$('#first input[type="checkbox"].option').prop('checked', true);
}
});
// second select all
$('#second .select-all').click(function() {
if ($('#second .select-all:checked').length == 0) {
$('#second input[type="checkbox"].option').prop('checked', false);
}
else
{
$('#second input[type="checkbox"].option').prop('checked', true);
}
});
// for your purposes you can remove this timeout
// I've only added it so you know that it works
setTimeout(function() {
var options = $('#second .option');
var totalCheckboxes = options.length;
var checked = 0;
options.each(function(index) {
if ($(this).is(':checked'))
{
checked++;
}
});
if (totalCheckboxes == checked)
{
$('#second .select-all').prop('checked', true);
}
}, 2000);
});<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<!-- Here I'll show you how to select and deselect all checkboxes-->
<div id="first">
<input type="checkbox" value="all" class="select-all"> Select all <br>

<input type="checkbox" value="2" class="option"> Option 2 <br>

没有冒犯，但你的代码太可怕了，你应该考虑使用像Laravel这样的MVC框架。
