I'm trying to create a popup after a user successfully sells a stock. I want it to look like Chrome's confirm form resubmission popup Popup

I'm pretty sure I need javascript, html, and css, but I'm not sure how to do it.



  • If you know how to program another type of popup that's fine, please tell me how.

If you want to use the popup window for any browser you probably want to use javascript. The popup window you have above is called a confirmation box. Here is how to use it:

function foo() {
    confirm("Message to be displayed");

The above function should be inside a <script> tag.

Then on your <input> tag with type="submit" also define the onclick attribute like that:

<input type="submit" value="submit" onclick="return foo();" />

  • Where would I put this js (what folder- public or templates) and also how would I make my php code run it?

  • You can put it in the <head> part of your HTML code. And you can have HTML code in your PHP file. Ha thanks for the other comment. I'm sorry if I appeared hostile with your Q&As. Just like you I'm trying to make this site better, and those where the questions in my review queue.
