Setting to not include onSubmit / JavaScript?

  • August 3, 2010

Hello,

I'm using the cfform tag (and cfinput) in my pages.  When looking at the generated code for one of the pages ('view source' in the browser), I noticed an onSubmit was added to the form tag with a call to some javascript.  The javascript is in the head section but is commented out.  Since this javascript isn't being used, I'm wondering if there's a setting to not add the onSubmit / javascript in my pages.

I'm using CF 9

Thanks

    Is that what the OP meant?

    Those are HTML comments.  They have nothing to do with JavaScript.  All that's for is hiding JS from browsers that don't understand JavaScript.  The JS engine ignores them.

    Can you post this commented-out JavaScript?

    Or some CF code that - when we run it - demonstrates this happening?

    I can.

    This code:

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <title>Untitled Document</title>
    </head>
    <cfsetting showdebugoutput="no">
    <body>
    <cfform action="abc.cfm" method="post">
    <cfinput name="x">
    </cfform>
    </body>
    </html>

    produces this html source code.  Note the html comments inside the script tags.  As I said earlier, the js still functions.

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml">

    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
    <title>Untitled Document</title>
    <script type="text/javascript">
    <!--
        _CF_checkCFForm_1 = function(_CF_this)
        {
            //reset on submit
            _CF_error_exists = false;
            _CF_error_messages = new Array();
            _CF_error_fields = new Object();
            _CF_FirstErrorField = null;


            //display error messages and return success
            if( _CF_error_exists )
            {
                if( _CF_error_messages.length > 0 )
                {
                    // show alert() message
                    _CF_onErrorAlert(_CF_error_messages);
                    // set focus to first form error, if the field supports js focus().
                    if( _CF_this[_CF_FirstErrorField].type == "text" )
                    { _CF_this[_CF_FirstErrorField].focus(); }

                }
                return false;
            }else {
                return true;
            }
        }
    //-->
    </script>
    </head>

    <body>
    <form name="CFForm_1" id="CFForm_1" action="abc.cfm" method="post" onsubmit="return _CF_checkCFForm_1(this)">
    <input name="x" id="x"  type="text" />
    </form>

    </body>
    </html>

    The javascript is being used. Otherwise things like the required attribute wouldn't work.
