我有一个内置的javascript，它可以执行以下操作: 通过ajax-> php-> sql获取内容，并将其显示在index.php上 单击内容后，将显示新内容.

<script id="source" language="javascript" type="text/javascript">
function laden(){
$(function() 
{

$.ajax({                  
`usr_id`                    
  url: 'content/get.php',              


  dataType: 'json',                   
  success: function(data)         
  {
    var id = data[0];             
    var name = data[1];

    var count = data[3];


    $('#output').html('<div onclick="laden('+id+')" id="content"></div>');

  } 
});

})； } `

}); } `

推荐答案

您可以通过在jQuery.ajax data设置中包含值来将数据发送到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，要将数据发布到回调脚本中，您可以执行以下操作:

You can send data to the callback script, specified in the URL, by including values in the jQuery.ajax data setting. Depending on what type of request you're making, this data will either be included in the $_GET or $_POST global variables. For example, to POST data to your callback script, you could do:

$.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...
  } 
});
