Question

so i have a .js file that 2 different jsp pages call.

.js file contains:

var savedObj;

function A(obj){ savedObj = obj);

function B(){ alert(savedObj);

X.jsp file calls function A such that a DOM element onchange = functionA(this);

Y.jsp file calls function B such that body onload = function B

For some reason, my debugging in function A shows that the assignment of savedObj = obj worked correctly, but in function B, savedObj printed out null.

Thanks guys

Using a cookie to store the value is certainly the best way to make the value persist across various pages. If you don’t want to go into cookies, you could use javascript to write the new page in place of the current page and keep the value, but it’s messy and you’re better off taking the time to learn cookies.
