blocking - Make Javascript document.write with script tag Block -

does know how can make document.write script tag block execution?

<script type="text/javascript">     var test = "bad";     document.write('<script type="text/javascript" src="js.php"><\/script>');     console.log(test); </script> 

where js.php is

<?php sleep(1); echo "var test='good';"; ?> 

console.log should output "good", outputs "bad". of course, after second, var change "good", need blocking. thanks!!

i kind of see whats happening. looks document.write in current script block gets written right after current script block.

do ajax call load more data. unlikely customizable. can jquery , json.
