onSubmit, run a javascript, return true or false

[cssExp]

hello,

i want to check for errors on submitting a form, on encountering an error it runs a function and returns a false preventing form submit. I have implemented that.

function eCheck()
{
 var filePath = document.getElementsByName("fileSelect");
 
 if (filePath == '')
 {
  errorPath();
  return false;
 }
 
  return true;
}
 

<form action="process.php" method="post" onSubmit="return eCheck();">
 

When i do the above, it isn't going through the check or rather not running the function errorPath(); and returning the value as false.

but when i do the following, errorPath(); works and form submit is called off.

<form action="process.php" method="post" onSubmit="errorPath(); return false;">
 

but i want it to run the error check. Any ideas on way it's not working.

Thanks in Advance.

Can you show the code for errorPath().

it only makes a div viable from hidden, nothing more is in it :)

var filePath = document.getElementsByName("fileSelect");
 
if (filePath == '') {
    // do something
}
 

hi ...

filePath is a node-list the way you call it - so it will never be a single value ...

use getElementById or loop through the list, or refer element with index=0 or something like that ... and compare the VALUE ;)

kind regards

Oh, I missed that. I see what the OP tried to do. You should use getElementsByName for radio buttons and checkboxes to loop over them.
