我不知道什么是处理Ajax使用jQuery调用的最好方法？现在我在做类似如下：

I'm wondering what is the best method to handle AJAX calls with jQuery? Right now I'm doing something like following:

$("#test").live('click', function(){
    // Process form
    $.ajax({
        type: "post",
        url: "test.php",
        success: function(html){
            if(html.success == 0) {
                alert('Error');
            } else {
                var obj = $.parseJSON(html.rows);
                $("#success").html(obj[0].name);
            }
        },
        dataType:'json'
    }); 
    return false;
});

在test.php的文件，我检查，如果请求是一个AJAX请求。如果它是一个Ajax请求我运行一个数据库查询，得到一些数据（这部分是不是在这个问题很重要，我认为）：

In test.php file, I'm checking if request is an AJAX request. If it's an AJAX request I'm running a database query to get some data (this part isn't important in this question, I think):

// query goes here
if(mysql_num_rows($query) > 0 ) {
    $result['success'] = 1;
    $result['data'] = json_encode($data);
} else {
    $result['success'] = 0;
}

现在我想知道如果我的方法是最好的？仅供参考我使用KohanaPHP目前的框架，所以我想不会打破MVC的规则。如果我做错了，你有什么提示和建议如何处理控制器AJAX调用？

Now I'm wondering if my method is the best possible? FYI I'm using KohanaPHP framework currently, so I want to not break MVC "rules". If I'm doing it wrong, do you have any tips and suggestions how to handle AJAX calls in controllers?

推荐答案

你有什么好看在这里，虽然我不认为你需要一个 $。parseJSON（）那里，它应该已经是一个对象在该点，这应该工作：

What you have looks good here, though I don't think you need a $.parseJSON() there, it should already be an object at that point, this should work:

$("#success").html(html.rows[0].name);

作为一个侧面说明，从可读性/可维护性的角度来看，我会重命名 HTML 参数是数据，像这样的：

As a side note, from a readability/maintainability perspective, I'd rename your html argument to be data, like this:

success: function(data) {

这纯粹是preference，但使用 HTML 时，它是一个HTML类型的响应，而数据或别的东西时，它的JSON /已经你期待的对象让事情有点更容易阅读为外人道。

This is purely preference, but using html when it's an HTML type response, and data or something else when it's JSON/already an object you're expecting keeps things a bit easier to read for outsiders.
