brixon (Kris Brixon) — Sat, 08 Dec 2007 02:23:25 GMT

ColdFusion - Compare two directories and report:
1. What files exist in folder A, but not B.
2. What files exist in folder B, but not A.
3. What files exist in both, but appear different.

Email a JavaScript Error using ColdFusion

werewolves (KRK) — Fri, 15 Dec 2006 04:13:53 GMT

This script emails an administrator when an error occurs, and could easily be adapted to log the error instead



/*

wwJsError (requires prototype.js)

		send:	sends javascript error output email via coldfusion

		--------------------

			path:		relative path from the calling page to the coldfusion

					email handler for this application (usually processJSerror.cfm)

			funcname:	name of the JavaScript function that threw an error

			name:		JavaScript error name (usually e.name in a catch block)

			message:	JavaScript error message (usually e.message in a catch block)

*/

var wwJsError = {

	send: function(path,funcname,name,message) {

		try {



			var url = path;



			var pars = 'message=' + escape(message) + '&name=' +

					escape(name) + '&funcname=' + escape(funcname);

			

			var httpMail = new Ajax.Request (

				url, 

				{

					method: 'post', 

					parameters: pars, 

					onComplete: Prototype.emptyFunction

				}

			);

	

		} catch (e) {

			//if sending the email fails, just die quietly w/ no browser error

			Prototype.emptyFunction();

		}

	}

}; //end wwJsError

Sample server-side script in ColdFusion



		subject="#application.apptitle# Error" type="HTML">

	JavaScript Error: #form.funcname# threw the following error:


	


	Error name: #form.name#


	Error: #form.message#

Generate the error



function makeError() {

	try {

		alert(anError);

	} catch(e) {

		wwJsError.send('cf/processJSerror.cfm','makeError()',e.name,e.message);

	}

}

Result by email

JavaScript Error: makeError threw the following error:

Error name: TypeError
Error: 'anError' is undefined

Clean magic quoting in ColdFusion 5 and later

keith (Keith Gaughan) — Fri, 17 Mar 2006 23:53:51 GMT

I'm updating my weblog software and needed some code to properly convert typewriter quotes to proper typographer's quotes.





function magicQuote(txt) {

    // Left quotes

    txt = REReplace(txt, "(^|[ " & Chr(9) & Chr(10) & Chr(13) & "'])""", "\1&##8220;", "ALL");

    txt = REReplace(txt, "(^|[ " & Chr(9) & Chr(10) & Chr(13) & "]|&##8220;)'",  "\1&##8216;", "ALL");



    // Right quotes

    txt = Replace(txt, """",        "&##8221;",  "ALL");

    txt = Replace(txt, "'&##8220;", "'&##8221;", "ALL");

    txt = Replace(txt, "'",         "&##8217;",  "ALL");



    return txt;

}

ColdFusion 5 has problems with \s, and the character class is a workaround for this.

Sorry, you need to provide at least one tag

Customtag to remove blank lines

browzer (Constandinos) — Tue, 07 Mar 2006 18:26:22 GMT

// description of your code here
Coldfusion output has a lot of useless blank lines and makes the HTML code hard to read. I use this customtag to remove the blank lines.
