javascript - How to get CodeMirror value without defining variable? -

i'm using multiple codemirror areas on page , im defining them in js:

function editor(id){   codemirror.fromtextarea(document.getelementbyid(id), {     linenumbers: false,     styleactiveline: true,     matchbrackets: true   }); } 

and later call function on textareas -

$j = 0; while($row = mysql_fetch_array($formulas)) {   echo "   <textarea id='code".$j."'>;some code</textarea>   --not important code--   <script>editor('code".$j."');</script>";   $j++; } 

and later, according solution site i'm refreshing part of codemirrors because of placing them in hidden div this

settimeout(function() {   $('.my-hidden-div .codemirror').each(function(i, el){       el.codemirror.refresh();   }); 

now need values of codemirrors blocks clicking in button in same row , send them via ajax problem appears.

how can value of them using $(this).closest('tr') guys? important me not define codemirror variable because i'm supporting dynamic deleting , adding new codemirrors textareas. anyway if did it, getting error js cannot recognize variable, defined in other js function , it's not global. me guys , have nice day. greetings.

the same thing you're using call refresh, accessing codemirror property on dom node, can used call getvalue well.
