Use iframe to pretend to submit forms Asynchronously

Source: Internet
Author: User

Asynchronous form submission, but cross-origin is required. POST is unreliable. Fortunately, YUI3 provides a powerful Y. Get. script module. Later, the great dumpling brother said, You can directly submit it using Form, Nana? Let's look at the Code:

<Iframe name = "mangguo"> </iframe> assume there is a form:

<Form method = "post" action = "http://www.mangguo.org/index.php" target = "mangguo">
<Input type = "text" name = "test"/>
<Button type = "submit"> submit a form </button>
</Form> after submission, the data is sent to the http://www.mangguo.org/index.php page, but because target = "mangguo" is specified, it is not opened in the current window (that is, the effect of not refreshing the page ), it is opened in iframe of name = "mangguo.

For details, see the demo:

<! DOCTYPE html> 

Tip: the code can be modified before running!
