Mouse over on hyperlink that shows what was selected on previous page

mldardy · August 15, 2016

Can someone assist me on how to do a mouse over on a hyperlink that shows what the user selected on the page they just left or saved. For example, the user clicks a link that says 'Add' and it opens a popup window where they select a list of items that have checkboxes, they check the items they want and then they click save to close the popup and they return to the original page. The user then hovers over another link that says 'Edit' and it shows them what they selected on the popup page. Can this be done and if so how?

Javascript can use the web storage API, but I would recommend doing it on the server-side, with a language like PHP. PHP has the $_SESSION system.

I was able to get something but I get a "LabelHover() is undefined" error. Here is my code. What do I need to do to get rid of this error.

You can't put a <script> tag in a <title> tag, and the Javascript should not be run on the server, it has to run on the client. Remove runat="server" from the HTML.
