I have such code:
<body>
<script>
window.nix = window.nix || {} ;
nix.falkorCache = 1;
</script>
...
I want to get nix variable with jQuery.
How can I access it?

As you wrote it, it should work. Anything assigned to window can be accessed as if it were a top-level value, i.e.,:
console.log(nix.falkorCache); // should work
If it's telling your that nix is undefined, the most likely culprit is that you are trying to access it before it is there.
In your HTML, that segment of code should be above any code that tries to access it, i.e.:
<body>
<script>
console.log(nix.falkorCache); // bad
</script>
<script>
window.nix = window.nix || {};
nix.falkorCache = 1;
</script>
<script>
console.log(nix.falkorCache); // good
</script>
That's the most likely culprit for your problem is just having it in the wrong order. If you're pulling in a <script> tag, you should put it at the bottom of your body element.
If that doesn't work, a few less likely culprits are:
- Ensure you aren't accidentally setting
nixtonullorundefinedin between the two. - Ensure you aren't trying to run the other code in an
<iframe>or something. - Ensure that you don't just have a simple typo somewhere.

Thanks. But the order is fine. The only problem that
window.nix = window.nix || {}; nix.falkorCache = 1; creates after the page load. Could it be the reason why the variable is not accecable?

@KirMazur I'm not sure what you mean by after the page load. If your page refreshes, all data is lost and it all has to be created. Otherwise, it's all about the order. If it is created after it is tried to access, that's no good. Can you update your answer with a more complete example of your call?
