Limit Word Count of A Textfield in JQuery -

-

I am modifying some jquery code to limit the word count of a textfield but I can not understand that How to value Here's the code: 

  & lt; Script & gt; Var $ limitWords = 20; Var $ wordCount = $ ('# count'). Val (); $ (Document) .ready (function () {$ ("# edit-field-message-0-value"). Keyup (function () {$ ('# count'). Html ($ ('# edit-field ($ WordCount & gt; $ limitwords) {$ ('# edit) AddClass (' error ');} and {$ (' # edit-field-message-0-value '). AddClass (' not-error ' );}}}}}; & Lt; / script & gt;

Specifically, to return the current value, should be equal to "$ wordCount"?

I think it should be easy, but I do not think so

any thoughts?

Thank you, Scott

I did not understand enough $ wordCount variable Believe that you can try to do the following: 

  $ ("# edit-field-message-0-value"). Key (function () {var $ this = $ (This); var wordcount = $ this.val (). Split (/ \ b [\ s, \ .---;; * /) Length; if (wordpress> $ limit words) {$ this AddClass ('Error');} and {$ this.addClass ('No-Error');}});

I'm also guessing that you can store the current calculation Want: 

  $ ("# edit-field-message-0-value") .keyup (function () {var $ this = $ (this); Var wordcount = $ this.val (). Split (/ \ b [\ s, \ .-:;] * /) Length; If (wordcount & quot; $ limitWords) {$ ('# count') Html ($ limitWords); $ This.addClass ('Error');} and {$ ('# Count'). Html (wordcount); $ This.addClass ('no-error');}});

asp.net - Javascript/DOM Why is does my form not support submit()? -

This is my first time working with asp.net and javascript, so I do not know very good web resources, or Much about javascript debugging I have to find out that on line oFormObject.submit (); Microsoft JScript Runtime Error: Object does not support this property or method I am using the link to work as a button because I am terrible in aesthetics and I think That link will look more professional than a table of 50 buttons. I have read that this solution can cause problems with browsers due to pre-rendering of my links and many additional traffic and problems, but CSS gives me a button like a link, which has issues of alignment and difference seemed to. & lt ;!

I am trying to implement one for Delphi, but there are some problems with communication. Fitnesse will start my process, and give me a portmember as a command line argument.

javascript - Classic ASP "ExecuteGlobal" statement acting differently on two servers -

-
I have a strange problem that I really do not know. In addition to developing a new ASP.NET site, I have to support the old "classic ASP" site. It is written in VBScript with a batch of JavaScript functions. Many of the JavaScript functions include 'files' Everything is fine on our production system (which security is controlled by another group - this is a military installation) Debugging them once did not work I). However, I have a fix for a vague bug that needs to be fully tested and some functions do not run under the "local" copy of the website that runs on my PC. For the record, I am running IIS 5.1 on XP. The problem is that some Javascript functions are running "OK" on the production server, but when they use it as a server, they are not defined on my PC what is happening that last Programmer, for some reason, has decided to put some functions in a series of files, which according to the observations, imitate the "need_once
