如何在没有url的情况下将jquery变量传递给php变量？

I need to get jquery variable to php variable using Ajax. I would be very grateful if anyone can help me.

我需要使用Ajax获取jquery变量到php变量。如果有人能帮助我,我将非常感激。

$(document).ready(function() {
    $('#roomOptions select').change(function() {
        var total = 0;
        $('#roomOptions select').each(function() {
            total+=parseInt($(this).val());

        });
        $('#roomOptions #roomOptions_total').html(total);
    });
});
</script>

If you want to pass some data from the client side to the server side, use AJAX, you can choose to send the data as GET or POST

如果要将一些数据从客户端传递到服务器端,请使用AJAX,您可以选择以GET或POST方式发送数据

$.ajax({
    url: full_url,
    type: 'POST',
    data: {"x":1,"y":2}
    success: function(result)
    {
        // do somthing
    }
});

You clearly can't. PHP is executed first and then jQuery is executed.

你显然不能。首先执行PHP,然后执行jQuery。
