  • what do you mean by current directory
  • The user must first "upload" the file to the page before you can select it. You can't access a file without the user consent. Or is the file on your server? Then you need Ajax, not FileReader.
  • looking at the API docs, this is an asynchronous operation. Your result will only be valid when loading is done. developer.mozilla.org/en-US/docs/DOM/…
  • My result from the above code is undefined. Not a file that is uploaded by user. Is a text file together with my html file and javascript file in a common file directory.
  • Thanks. This helped me on a couple of my pages, but now I need to figure out how to make the script source a variable, which I pass to the new page through local storage.
  • Javascript can't do it alone, so use a PHP call to save the variable, then another PHP call to load it with the other page. Example, with a php file called save.php -- <?php $myvar = $_REQUEST['myvar'];file_put_contents('myfile', $myvar); ?> -- and read back with a file called read.php -- <?php $myvar=file_get_contents('myfile');echo $myvar; ?> -- In javascript pass the variable to the save.php function using jquery, $.get("save.php?myvar="+myvar, function(data){content=data;}); -- and read back using $.get("read.php", function(data){myvar=data;alert(myvar);/*your function here*/;});
  • Please describe your problem in brief with code eg.
