Undefined global variable

Within my function, I have defined a global variable called window.playerLibrary. Interestingly, when I check the value of window.playerLibrary within the function itself (`var check #1`), it returns a value. However, if I try to check it just outside of the ajax call or after calling the function, the variable is undefined:

function generateAllCards() {
    $.ajax({
        type: "POST",
        url: "processGame",
        data: {
            mode: "generateCards"
        },
        dataType: "JSON",
        success: function(data) {
            window.playerLibrary = data.playerLibrary;

        // var check #1
            console.log(window.playerLibrary);
        }
    });

// var check #2
    console.log(window.playerLibrary);
}

generateAllCards();
// var check #3
    console.log(window.playerLibrary);

Reflecting on this issue, I suspect that the variable definition within the ajax call is not being captured during checks #2 and #3 due to sequencing. Is there a solution to address this problem?

Answer №1

Perform required actions on the playerlibrary within the success callback, or trigger a function from there after confirming the value assignment
