Can't read global variables in a javascript function :(

I am having a strange problem with global variables disappearing on me. Here is some stripped down semi-pseudo-code:

var globy = 99;

jQuery.get("file", function(){
  check();
})

function check(){
 main();
}

function main(){
 forloop
  whileloop
   forloop
    while(test()){}
}

function test(){
  //globy causes a reference error here
}

That should explain the code structure. All the way up to the test() function "globy" is fine bu开发者_StackOverflow社区t suddenly inside test() all global variables disappear. What the heck?

If you are wrapping everything in a $(document).ready() but have your test() function outside of the document ready you will have a scoping issue.

$(document).ready(function () {
    var globy = 99;

    jQuery.get("file", function () {
        check();
    })

    function check() {
        main();
    }

    function main() {
        forloop
        whileloop
        forloop
        while (test()) {}
    }
});

function test() {
    //globy causes a reference error here
}

Besides that it will be hard to say without the real js.

Your test() function is probably defined outside the scope where globy resides. Without more detail, it's hard to say.
