如果我单击1然后选择2,则取消选中该复选框,并显示一个警告,如果我再次单击2则没有警报!我确定我将前一次检查的值存储在2,我需要撤消这个!
<script>
$(function() {
var lastChecked = [];
$(':checkbox').change(function() {
if (this.checked) {
if (lastChecked.length && this.value != lastChecked[0].value) {
$(this).prop("checked", false)
alert("the last box you checked has a different value");
}
lastChecked.unshift(this);
}
else {
lastChecked.splice(lastChecked.indexOf(this), 1);
}
});
});
</script>

由于您取消选中此框,因此不应将该复选框存储在lastChecked
数组中。只需将lastChecked.unshift(this)
包裹在else
块中。
