jquery - Disable original javascript keypress event and replace dynamically -

-

Currently I have a teddyrea with an onkeypress event specified in the HTML tag, I capture this funnel and form a function I am trying to save in that it will be used to override it, because I want to add another condition to run it. Here's the code that I'm trying to implement. 

  $ (document) .ready (function (e) {var default keypress = $ ('textarea') keyboard; $ ('text') .keypress (function (e) {if (FieldsChanged) {fieldsChanged = false;} else {defaultCeypress (e);}});});

The problem I have is IE 7 & amp; 8. Both the original keyboard fire (even though the "default keypers (e);" are commented on) and the new keypress is activating. In addition to removing the onkeypress attribute from the Textarea tag (original first, then new) (I can not do this because the code is generated), is there a way to disable that basic keyboard with firing?

Thank you! Newtube

jQuery keypace Handler You pass it and do not overwrite anything No It is too much by design, in this way you can add many event handlers to the element and worry about catching any existing handlers. do not require.

You can not actually use unbind to prevent existing handlers want to stop the existing handler. You can only remove the handler anyway, however: 

  var $ el = $ ('textarea'), defaultKeypress = $ el.attr ('onkeypress'); $ El.removeAttr ('onkeypress'); $ El.keypress (function (e) {if (fieldsChanged) {fieldsChanged = false;} else {return default keypress.apply (this, argument);}});

Note that I use defaultKeypress by calling return as well as making a call with the correct scope. Code> using the result of return. This is to maintain all standard event handler environments, which the browser has called it.

    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. Then I should make a socket on the port number given to me, and fitness will connect to that port I am using a TCPCP server for the job: < Pre> TcpServer1.LocalPort: = ParamStr (ParamCount); TcpServer1 Active: = true; On OnEXEPT () -Event, I send the protocol version to use as specified in the protocol. Process TForm1.TcpServer1Accept (From: TOBject; ClientSocket: TCustomIpClient); Var s: ansistring; Start clientSocket. Syndrome ('slim - v 0.0', # 10); SetLength (S, 6); ClientSketts Receavebook (S, 6); End; When I call ReceiveBuf (), the process ends, and fitness throws an exception: java.net.SocketException: connection Reset I have seen what sent and received. It shows that my code sends the protocol version, fitness sends back a message, and when I try to get this message

    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
