在重定向页面上获取所选项目-如何？

Question

Our site's UI displays read-only text fields which have mouse-click handlers -- when the user clicks one of the read-only fields, we change its CSS to make the text and background color of that item appear "selected."

If the user clicks a 'show item' button on this same page, the next page needs to 'know' which item was selected on the page that it was redirected from.

PAGE A: user clicks a read-only field to select it; the selection is highlighted via CSS .........and user can click a 'Show Item' button on this page to see the details of the selected item -- we redirect to Page B to show the selected item's details. The 'Show item' will NOT be a form 'submit' button, just a standard button.

PAGE B: Gets redirected to. Needs to know what item on Page A was the selected item (using the item's ID or value etc.)

How? If you are inclined to say 'Ajax' don't bother, I do not have that in my allowed suite of options, nor jquery, those are my marching orders.

The onclick handler is client-side code on Page A. The redirection is via window.location="page2.php"

I do not see any way that Page A can make Page B aware of the selected item's name or ID or etc. -- it's not a form post, it's all client side code.

Although I might be missing something, pls let me know if I am. I'm stuck right now.

Reaching for straws, I thought of calling submit() but I don't think I can pass anything that way that would allow Page B to know which item on Page A was selected, besides the fact that submit() requires A-Form.submit() and the 'Show Item' button is not on a form on Page A.

Answer 1

capture the click event and return the target's id. pass the target's id as a url param on the redirect.

Answer 2

when redirecting just append required information with # prefix like this : window.location="page2.php#1,2,3,4" and then on the page2 parse those values using JS.

you can access values you have passed by window.location.hash in JS

Answer 3

In your onclick event handler, execute an ajax request to your server that performs something like

<?
session_start();
$_SESSION['selectedVariable'] = intval($_GET['foo']);
?>

Next page load, your site will know, as it is stored in the session.

Of course, this won't work really well with multiple tabs.
