javascript - 如何使用jquery / ajax将变量发送到php文件，然后将php回显到索引（无警报）(How to send variables to php file with jquery/ajax and then echo the php to index (no alert))

Question

I'm a newbie around here and I've run into a dead end.

(我是这里的新手，已经走到了死胡同。)

So I've created a function to draw a calendar in php.

(因此，我创建了一个在php中绘制日历的函数。)

And I've been using css to set the colors of days and that stuff.

(而且我一直在使用CSS来设置日期和其他内容的颜色。)

The function runs well and uses 2 input variables like this:

(该函数运行良好，并使用了两个输入变量，如下所示：)

PHP file (calendar.php):

(PHP文件（calendar.php）：)

<?php
function draw_calendar($month,$year)
{
// the code
}
echo draw_calendar($current_month,$current_year);
?>

What I've been trying to do is use jquery/ajax (from my index file) to post/get variables to calendar.php for $current_month and $current_year to use.

(我一直想做的是使用jquery / ajax（从我的索引文件中）将$ current_month和$ current_year的变量发布/获取到calendar.php中。)

And then echo the function to my index somehow.

(然后以某种方式将函数回显到我的索引。)

For the life of my I can't manage to do that.

(在我的一生中，我无法做到这一点。)

I could only find how to return simple strings and alert them to my index.

(我只能找到如何返回简单字符串并将它们提醒到我的索引。)

I am not sure what code you have written up, but her is the general idea of how you can use ajax to send over your needed variables.

(我不确定您编写了什么代码，但是她是您如何使用ajax发送所需变量的基本思路。)

On your index file:

(在索引文件上：)

var month = "11"; //your month
var year = "2019"; //your year

$.ajax({
  type: "POST",
  url: "calendar.php",
  data: {month: month, year: year},
  dataType: "json",
  success: function(response){
    //if it is success
  },
  error: function(){
    //if it results in error
  }
});

On your calendar file:

(在您的日历文件上：)

$month = $_POST['month'];
$year = $_POST['year'];
