来自PHP的JSON数组在主JS文件中未定义编码

Question

I have today a very strange problem with JS array. First, I am encoding JSON array in php and echo an array:

echo '<script type="text/javascript">var odpowiedzi = []; var odpowiedzi = '.json_encode($_SESSION['odpowiedzi']).'; alert(odpowiedzi);</script>';

What is interesting, I see here that alert with good data of my array but in 2nd JS file I am trying to see it again:

alert(odpowiedzi[0]);

And only thing I get is critical JS error of undefined:

VM5244:7 Uncaught TypeError: Cannot read property '0' of undefined

What is the problem? For test I made same thing with normal int variable and it is working! Please for help.

Looks to me like your second JS file is getting loaded first. You can simply add console.log() commands and log the time when they get called to see if there's an issue with the order of your scripts getting loaded as such;

console.log('nth block execute time: ' + new Date().getTime());
