推荐答案

有几种方法可以解决这个问题。您可以创建一个非提交类型的按钮，然后使onclick事件禁用该按钮。



您还可以捕获表单提交事件，并禁用提交按钮。





如果你以后遇到它，我发现再次启用按钮的最好方法是完全删除disabled属性，不要将它设置为false等。

There are several ways to go about this. You can make a button that is not of type submit, and then make the onclick event disable the button.

You can also catch the forms submit event, and disable the submit button.


In case you run into it later, the best way I have found to enable a button again is remove the disabled attribute altogether, not set it to false etc..
