< button type =" submit">与onclick提交两次？ [英] <button type="submit"> with onclick submitting twice?

问题描述

我目前正面临一些重复订单问题。没有详细说明，我对以下内容有疑问。是否有可能触发提交两次？

< button type =submitonclick =review.save（） >< / button>

review.save（）提交表单 - 所以实际上这里不需要type = submit。但是我想确定这个CAN是否会导致浏览器提交两次。在服务器日志中，2次提交相距约10秒。

解决方案

您需要防止默认浏览器行为，例如：

 < button type =submitonclick =review.save（）; return false;>< / button> ; 
  

I am currently facing some order duplication issues. Without going into too much detail, I had a question about the following. Is there any possibility that this can trigger a submit twice?

<button type="submit" onclick="review.save()"></button>

review.save() will handle the submission of the form - so in fact the type=submit isn't needed here. But I want to establish whether this CAN cause the browser to submit twice. On the server logs the 2 submits were about 10 seconds apart.

解决方案

You need to prevent default browser behaviour, for example:

<button type="submit" onclick="review.save(); return false;"></button>
