Passing data-* to bootstrap Modal

问题

I have seen the many search results for passing data to a modal, all with possible working but different solutions. I have a MySql DB, with a very simple single table. I am using PHP echo to echo the data to a HTML table. The final <td> is a bootstrap button to trigger a modal. I am unable to get the included code to work to show the row data in the modal.

There are a lot of comments in here as I am learning.

Also can you let me know if you can add jQuery scripts inside the html and do they override the other jquery for that activates the modal?

回答1:

It is good to keep code more cleaner by using indent well.
<script ~~> is also a tag like div , p , h1 but it has display : none. So of course you can add <script> tag in html file. It's OK.
When Browser meet that <script src = "jquery.js">, the browser gets the jquery.js code from server ( in this case , your server ). So, You can't override other js code. It's just twice the work for the browser, and the jquery code is read twice.
I can't understand what are you doing, specifically the <script type="text/javascript" src="/js/jquery-3.1.1.js"> code. You already included jquery-3.1.1.js above! Why are you doing that?
Anyway, browser can not find #myModal in timing(or time?) that read the code $('#myModal').on('show.bs.modal', function (event) { ~~ . So the code should be under the model div.

Be Happy Coding ^^.
