我在 joomla 中为 ajax 使用这种格式

I'm using this format for ajax in joomla

$.ajax({
        type: 'GET',
        url: 'index.php', 
        data: {option: 'com_componenetname', task: 'taskname.youroperation', format: 'json', tmpl: 'raw'},
    dataType: 'json',
        async: true, // can be false also
        error: function(xhr, status, error) {
                console.log("AJAX ERROR in taskToggleSuceess: ")
                var err = eval("(" + xhr.responseText + ")");
                console.log(err.Message);
                },
        success: function(response){

                // on success do something
                // use response.valuname for server's data
                        }
                ,
        complete: function() {
            // stop waiting if necessary 
                 }                     
          });

在您的组件/控制器中，您应该有一个文件 yourcontroller.json.php 它将处理您的调用并返回编码的 json 数组将您需要在客户端中的所有数据

In your component/controllers you should have a file yourcontroller.json.php which will process your call and return encoded json array will all the data you need in the client
