问题描述
我有一个向数据库提交信息的表单。我怎样才能这样做,当我点击提交按钮时,我会收到一个警告,询问我是否真的要提交它,当我点击是时它会继续,如果我点击否它就不会提交信息。
I have a form that submits information to a database. How can I make it so that when I click the submit button, I get an alert that asks me if I really want to submit it and when I click "Yes" it continues and if I click "no" it does not submit the information.
推荐答案
使用JavaScript confirm()
功能。
Use JavaScript confirm()
function.
<input type="submit" onclick="return confirm('Are you sure?')">
如果用户选择是,它将返回 true
并且按钮的默认操作(提交表单)将照常继续。但是如果用户选择否,它将返回 false
,并且该按钮的默认操作将被阻止。
If the user chooses Yes, it will return true
and the button's default action (submitting the form) will continue as usual. But if the user chooses No, it will return false
and the button's default action will be blocked.
