How To Access A Variable Set Within An Ajax Call

I'm trying to set a variable within a function that calls some PHP code via Ajax. The problem is that the variable is not accessible from outside the function, so to say. var start

Solution 1:

You can pass your retured data as a parameter to your function.

function getSavedStartPage() {
    $.post(webroot + 'home/get_saved_startpage/',
    function(data){
        startPageSelected = $.parseJSON(data);
        alert(startPageSelected); //alert 1
        something(startPageSelected);
    });
}

function something(data) {
    alert(data); //alert 2
}
