When you do

onclick="onclick_edit(<?php echo 'aaa';?>);"

The result will be HTML

onclick="onclick_edit(aaa);"

You can confirm this by viewing the source code of your page. When trying to run, Javascript will try to pass the variable aaa to the function, giving variable error not defined (you can check in the console that).

In order to be able to do what you want, you need to display the value with quotes, so that Javascript understands how string:

onclick="onclick_edit(<?php echo "'aaa'";?>);"

So the result will be

onclick="onclick_edit('aaa');"
