Question

我需要使用Ajax和jQuery从HTML5编码页面发送表单。我不知道如何正确地将表单中的参数发送到Ajax和jQuery。如何正确发送？我的应用程序必须获取用户的推文（来自tweet.com），user_id和tweets amound是参数，必须将其输入到表单中。

Answer 1

将您的ajax呼叫数据设置为

data : $("#tweetshow").serialize();

Serialize（）将表单字段作为URL编码表示法中的字符串返回。

Answer 2

你可以做Barry所说的，也可以使用

data: JSON.stringify(params)

在你的Ajax调用中

。
