Declare variable outside of the function…
var oneVariable; function setVariable(){ oneVariable = "Variable set from within a function!"; } function getVariable(){ alert(oneVariable); // Outputs "Variable set from within a function!" }Or… attach it to the window object
function setValue() { window.myValue = "test"; } function getValue() { alert(window.myValue); // "test" (assuming setValue has run) }
don’t even need to specify “var” when you are declaring a global.
It’s a good practice use the “var” keyword.
It’s bad practice to declare globals…
ok, but some Time it’s absolutely necessary.
I have problem in css global variable assigning, is it correct? but it not working how to fix this?
