You can send data to the callback script, specified in the URL, by including values in the jQuery.ajax datasetting. Depending on what type of request you're making, this data will either be included in the $_GETor $_POSTglobal variables. For example, to POST data to your callback script, you could do:
通过在 jQuery.ajaxdata设置中包含值，您可以将数据发送到 URL 中指定的回调脚本。根据您发出的请求类型，此数据将包含在$_GET或$_POST全局变量中。例如，要将数据 POST 到您的回调脚本，您可以执行以下操作：
$.ajax({
url: 'content/get.php',
type: 'post', // performing a POST request
data : {
data1 : 'value' // will be accessible in $_POST['data1']
},
dataType: 'json',
success: function(data)
{
// etc...
}
});
