What is "traditional style of param serialization' in JQuery
提问by Ricky
Do you know what is "traditional style of param serialization" for jQuery.ajax() as mentioned in http://api.jquery.com/jQuery.ajax/?
您知道http://api.jquery.com/jQuery.ajax/ 中提到的 jQuery.ajax() 的“参数序列化的传统风格”是什么吗？
Can you give some introduction?

Have a look at the documentation of jQuery.param():
看看文档jQuery.param()：
As of jQuery 1.4, the
$.param()method serializes deep objects recursively to accommodate modern scripting languages and frameworks such as PHP and Ruby on Rails. You can disable this functionality globally by settingjQuery.ajaxSettings.traditional = true;.
从 jQuery 1.4 开始，该
$.param()方法递归地序列化深层对象以适应现代脚本语言和框架，例如 PHP 和 Ruby on Rails。您可以通过设置全局禁用此功能jQuery.ajaxSettings.traditional = true;。
Given
给定的
var p = {foo: [1,2,3], bar: 42};
setting traditionalto truegenerates
设置traditional到true生成
foo=1&foo=2&foo=3&bar=42
While e.g. Python can handle these parameters, i.e. it generates a list for foo, PHP will only consider the last fooparameter.
虽然例如 Python 可以处理这些参数，即它生成一个列表 for foo，但 PHP 将只考虑最后一个foo参数。
But now by default, the result of the serialization is (actually it is URI encoded)
但是现在默认情况下，序列化的结果是（实际上是URI编码的）
foo[]=1&foo[]=2&foo[]=3&bar=42
which can be better handled, as mentioned, by PHP and RoR.
如前所述，可以通过 PHP 和 RoR 更好地处理。
Or maybe even more interesting is this. Given:
或者更有趣的是这个。鉴于：
var p = {foo: {1: [3,4], 2:2,3:3}, bar: 42};
traditional produces:
传统产品：
foo=[object Object]&bar=42
which is clearly not useful in comparison with the "new" way:
与“新”方式相比，这显然没有用：
foo[1][]=3&foo[1][]=4&foo[2]=2&foo[3]=3&bar=42
