Function A computes a sum on a click event. Then the function ends. A new click event from another button runs function B. Can functtion B access the sum?
If so, how can this be done? Thanks.

You need to declare the variable at a higher scrope,preferably outside of all function and use the variable inside the function like given below
<script> //variable to hold the value var str =0; function addition(){ //assign value to variable str=10; } function SecondAddtion(){ //use the variable here var total = parseInt(str) +10; //show the output alert(total) } </script>
Complete Code:
<!DOCTYPE html> <html> <head> <meta charset="utf-8"> <script> //variable to hold the value var str =0; function addition(){ //assign value to variable str=10; } function SecondAddtion(){ //use the variable here var total = parseInt(str) +10; //show the output alert(total) } </script> </head> <body> <input type="button" value="Addition" onclick="addition();"/> <input type="button" value="SecondAddtion" onclick="SecondAddtion();"/> </body> </html>
