submit（）函数有回调吗？ [英] Does submit() function has a callback?

问题描述

  setMyCookie（'name'， 'value_1'）; 
 $（'。myform'）。submit（）; 
 setMyCookie（'name'，'value_2'）;问题：Webkit浏览器似乎在表单被提交之前用value_2更新MyCookie，或者，在确切的时刻，它被提交，所以错误的cookie值与它一起发送。 
我想在表单提交后立即将cookie值更改为'value_2'，以便cookie可以用于另一个请求。
 
 
 
以下代码可以正常工作，但我不认为使用timeout（）是最好的解决方案。也许有另一种方法来解决这个问题？
  setMyCookie（'name'，'value_1'）; 
 $（'。myform'）。submit（）; 
 setTimeout（function（）{setMyCookie（'name'，value_2）;}，100）; 
  
谢谢。
解决方案
否。提交表单会加载一个全新的页面，通常会结束脚本的当前执行上下文。
 
 
 
例外情况是如果您将表单提交到框架，在这种情况下一个onload事件将触发。
 
I have this code, and a file upload form which is submited to a frame:
setMyCookie('name','value_1');
$('.myform').submit();
setMyCookie('name','value_2');
Problem: Webkit browsers seem to update 'MyCookie' with 'value_2' before the form gets submited, or in the exact moment it is being submited, so wrong cookie value is sent with it.
I want to change cookie value to 'value_2' immediately after the form is submited so the cookie is ready for another request.

The following code works fine, but I don't think using timeout() is the best solution. Maybe there is another way to solve this problem?
setMyCookie('name','value_1');
$('.myform').submit();
setTimeout(function(){setMyCookie('name',value_2);},100);
Thanks.
解决方案
No. Submitting a form loads an entirely new page, which usually ends the current execution context for the script.

The exception is if you submit the form to a frame, in which case an onload event will fire.
