HTML - How to do a Confirmation popup to a Submit button and then send the request?
提问by Mona
I am learning web development using Djangoand have some problems in where to put the code taking chage of whether to submit the request in the HTML code.
我正在学习使用 Web 开发，Django并且在将代码放在哪里以决定是否在HTML code.
Eg. There is webpage containing a form(a blog) to be filled by the user, and upon click on the Save button,there is a pop up asking whether you want to confirmor not. If click on confirm, then the request is sent.
例如。有一个网页包含一个form（博客）供用户填写，点击保存按钮后，会弹出一个询问您是否要填写的信息confirm。如果单击confirm，则发送请求。
I searched and find this javascriptcode.
我搜索并找到了这个javascript代码。
<script type="text/javascript">
function clicked() {
alert('clicked');
}
<input type="submit" onclick="clicked();" value="Button" />
But I guess this is not the correct function as it seems to me that whenever you click on the Button, the request will be submitted. So How can I delay the submit request until user has confirm the submit?
但我想这不是正确的功能，因为在我看来，每当您单击按钮时，都会提交请求。那么如何延迟提交请求，直到用户确认提交？

The most compact version:
最紧凑的版本：
<input type="submit" onclick="return confirm('Are you sure?')" />
The key thing to note is the return
需要注意的关键是 return

Use window.confirm()instead of window.alert().
使用window.confirm()代替window.alert()。

<script type='text/javascript'>
function foo() {
var user_choice = window.confirm('Would you like to continue?');
if(user_choice==true) {
window.location='your url'; // you can also use element.submit() if your input type='submit'
} else {
return false;
}
}
</script>
<input type="button" onClick="foo()" value="save">

Another option that you can use is:
您可以使用的另一个选项是：
onclick="if(confirm('Do you have sure ?')){}else{return false;};"
onclick="if(confirm('你确定吗？')){}else{return false;};"
using this function on submit button you will get what you expect.
在提交按钮上使用此功能，您将得到您所期望的。
