submit 一个form以后怎么得到返回值

Answer 1

提交一个form会跳转到新的页面，也就没什么返回值的说法了，如果要在本页面获取返回值并应用的话，用ajax请求

Answer 2

submit Method

Submits the form.

Syntax

FORM.submit()
Return Value

No return value.

Remarks

The submit method does not invoke the onsubmit event handler. Call the onsubmit event handler directly. When using Microsoft® Internet Explorer 5.5 and later, you can call the fireEvent method with a value of onsubmit in the sEvent parameter.
