问题描述
我听说JSON序列化所有的数据,这阻止了我在客户端在跨浏览器支持等问题。
I've heard that JSON serializes all the data, which stops me having problems client side in terms of cross-browser support etc..
我已经使用AJAX与jQuery和它似乎很容易,但我不确定的差异,
I've been using AJAX with jQuery and it seems easy, but I'm unsure of the differences,
我读了我也可以使用这个来获取数据:
I've read I can also use this to get the data:
$.ajax({
url: url,
dataType: 'json',
data: data,
success: callback
});
任何人都可以解释使用JSON创建jQuery AJAX请求和创建jQuery AJAX请求而不使用json类型?
Can anyone explain the difference between making a jQuery AJAX request using JSON and making a jQuery AJAX request without the json type?
所有浏览器的答案都可以吗?
Will the answer be ok for all browsers?
推荐答案
AJAX代表 A 同步 J 抗性 nd X ML,这是一种用于使用JavaScript启动异步HTTP请求到服务器的机制。不要让这个名字愚弄你;您没有限制只从这种技术检索JavaScript或XML。您可以很高兴地返回其他数据格式(HTML,纯文本和JSON,以列出几个)。
AJAX stands for Asynchronous Javascript and XML, which is a mechanism used to launch asynchronous HTTP requests to a server using JavaScript. Don't let the name fool you; there's no restriction on you only retrieving JavaScript or XML from this technique. You can quite happily return other data formats as well (HTML, plain text and JSON, to list a few).
JSON只是其中一种格式。这是一种数据交换格式,因为AJAX是在启动页面加载完成后与服务器通信的技术。
JSON is just one of these formats. It's a data interchange format, where-as AJAX is a technique to communicate with a server after the initate page load has completed.
要回答您是否需要指定 dataType
的问题; jQuery最好猜测响应格式(无论是HTML还是JSON等),所以通常可以省略它。
To answer your question on whether you need to specify the dataType
; jQuery will best guess the response format (be it HTML or JSON etc), so you're usually fine to omit it.
