Hi, i want to access from a function in the <head> of the main page, to a global variable stored in an external .js already loaded before in the <head>.

Example:

PHP Code:


			
external.js:
 var question = new Array();
 question[1] = new Array();
 question[1]["q"] = 'Lorem Impsun?';
 question[1]["correctText"] = 'Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Proin suscipit dignissim wisi. Pellentesque mattis dolor ac mauris. Sed iaculis ante sit amet lectus. Quisque at elit nec est vulputate congue. Duis imperdiet quam id mauris. Nunc lacinia tortor. Vivamus est leo, laoreet ac, vehicula ac, adipiscing eu, odio.';
 ....
 etc.

and in the main file:

PHP Code:


			
 <script type="text/javascript" src="functions.js"></script>
 <script language="JavaScript">
 var exam_num = 1;
 function confirm(answer) {
         bannerDisplay.innerHTML = '<some_html_code_to_print_result>'+question[exam_num]["correctText"]+'</some_html_code_to_print_result>';
 }
 </script>

i cant access to 'question' var from the function..

Thanks in advance...

You probably can't access 'question' because it's globalized only within the first <script>-tag. remove the 'var'-statement and it should work better.
