问题 Now I made a procedure that activates on the click of a button. Now say I have a listbox called: selection = Tkinter.Listbox(b_action) selection.insert(1,"stuff") selection.insert(2,"morestuff") a = 0 How can I make that procedure run, each time I select a different part of the listbox? For example I first click "stuff" and then click "morestuff". Clicking "stuff" sets a to 1 and clicking "morestuff" sets a to 0 again. 回答1: You can create a dictionary mapping the actual listbox values with

问题 Okay, so I just noticed this issue. There has to be a way around it. Example... On page A.php and on page B.php, there is a link to page ALPHABET.php. ALPHABET.php receives specified variable values depending on which page is the referrer. All pages involved have session_start(); at the beginning. Page A.php has: <?php $_SESSION['name'] = "John"; ?> Page B.php has: <?php $_SESSION['name'] = "Jane"; ?> Page ALPHABET.php has: <?php $personName = $_SESSION['name']; echo "Hello, I am ".

问题 I'm stuck after several hours of banging my head up against the screen. I'm hoping someone with more knowledge can help me out. My ultimate goal is to take the parsed URL parameters and display them in the body of my Wordpress page. An example URL maybe 'www.urlexample.com/?var1=red&var2=shoes'. If I inspect my page, I can see in the session storage the key/value pair displaying. For example I would see key="var1" with a value="red". So to mean that means the javascript is working. Now how

问题 I'm aware of how to read set_fact across different plays. I have also read about issues regarding set_fact in another play. However, I did not come across any example where the set_fact used under a Play having dynamically constructed host using add_host and it now needs to be read by another play having hosts: localhost I was expecting host_vars to help me but the below playbook test shows that host_vars also does not help and I get a variable undefined error.

问题 I'd like to be able to use www.example.com/profiles/1234567890 instead of www.example.com/profiles?id=1234567890 but was unable to figure out how to do so. I found an apache equivalent here: Turn text after slashes into variables with HTACCESS but I don't know how to get it to work in Nginx. I only need the one variable which is id . Additionally, is it possible to do a rewrite such that www.example.com/id/1234567890 points to www.example.com/profiles/1234567890 but the url doesn't change?
