JavaScript log-in validation by-passed by IE8 -

-

I have a log-in web page that uses JavaScript for name and password verification. This Mozilla works fine in Firefox, but logging without entering IE8 names and passwords allows it to post a script-restriction warning that, when you click on it, you chose to enable javascript can go. It's okay, you can just bypass that step by clicking on the login button on the web page and you are in. This is a big problem. So this Javascript is not running, it defeats the entire purpose of the page.

The (HTML) form tag calls Javascript: 

 form name = "form1" action = This input tag has a log-in button: "testAccess.htm" onsubmit = "return butCheck_onclick ()"

: 

 input type = "submit" square = "center" value = "Log in"

I need some type of work - around so that I can either javascript before loading the next page Can turn the T I can do or say a few ways to prevent HTML allowing to load the next page before you run JavaScript. But then why would I need javascript if I can apply such restrictions in HTML? I hope I understand that thank you for any help you can give. --- Andy v.

Here I have the JavaScript function:

You should never authenticate on the client side. Always check your username / password on the server side.

For example, all I have to do is look at the source of the page and copy / paste the username and password. Copy

or even paste the destination URL only.

In addition, disabling JavaScript will definitely be sufficient.

The only validation that you can do on client side (at registration time) is determined if the values ​​entered are correct length, etc. (and duplicated on server side)

Edit: See some good advice from SO users on website certification.

I am programming a simple C # application, and I need a Scallow event on the list view. So I inherited the original ListView class created in ListviewEx witch. I found out how to locate the scroll message from WinAPI and I modified the WndProc method. Now I have this WndProc: protected override zero WndProc (Ref message message) {base.WndProc (Ref I); If (m.msg == WM_VSCROLL) {onScroll (This, New EventArgs ()); }} But the problem is, I do not know how to know about scrolling information. This data should be in wParam, but there is a LOWORD macro ++ like in C in C # and I switch to find the criteria like SB_ below, SB_ENDSCROLL, SB_PAGEUP etc. there any way Need to change the LOWORD macro from C #? Or any other way to find the necessary parameters about scrolling? You can define the WParam constants as the following: Private const int WM_HSCROLL = 0x114; Private Constant WM_VSCROLL = 0x115; Private contact int SBHOZZ = 0; Private Consultant SB_VERT = 1; Private Con...

Linux Terminal Problem with Non-Canonical Terminal I/O app -

-
I have a small app written in C to run on Linux. Part of the app accepts user-input from keyboard , And it uses non-canonical terminal mode so that it can respond to each keystroke. The section of the code that accepts input is a simple task that is called repeatedly in the loop: char get_input () {char C = 0; Int res = reading (input_tamille, & amp; c, 1); If (RSS == 0) 0 returns; If (res == -1) {/ * snip error handling * /} return c; } It reads a letter from the terminal if there is no input within a given time limit, (c_cc [VTIME] value in the vocabulary structure), read () 0 And get_input () is called again It all works very well, I have recently discovered that if you run this app in a terminal window, and then the app Close the terminal window without ending, the app will not exit Received, but CPU intensive launches into an infinite loop, where the read () returns 0 without waiting continued. So how can I get out of the apple if it runs from the terminal win...
