Can i know for what reason u are disabling the keyboard. for a particular field u can do that by the following method

[HTML]function doThis()
{
return false;
}[/HTML]

[HTML]<input type="text" onkeypress="return doThis();">[/HTML]

for this particular text box u cant enter anything. the key board behaves as blocked one. Is this ur requirement. you just post with some additional information about ur requirement

I once used this in the body to disable right-click (obviously this will need updating to the new format):

Expand|Select|Wrap|Line Numbers
  1. <script language=JavaScript>
  2. <!--
  3.  
  4. var message="Function Disabled!";
  5.  
  6. function clickIE() {if (document.all) {alert(message);return false;}}
  7. function clickNS(e) {if 
  8. (document.layers||(document.getElementById&&!document.all)) {
  9. if (e.which==2||e.which==3) {alert(message);return false;}}}
  10. if (document.layers) 
  11. {document.captureEvents(Event.MOUSEDOWN);document.onmousedown=clickNS;}
  12. else{document.onmouseup=clickNS;document.oncontextmenu=clickIE;}
  13.  
  14. document.oncontextmenu=new Function("return false")
  15. // --> 
  16. </script>
  17.  
and this to disable select with left click, in the head:
Expand|Select|Wrap|Line Numbers
  1. <script language="JavaScript1.2">
  2.  
  3. function disableselect(e){
  4. return false
  5. }
  6.  
  7. function reEnable(){
  8. return true
  9. }
  10.  
  11. //if IE4+
  12. document.onselectstart=new Function ("return false")
  13.  
  14. //if NS6
  15. if (window.sidebar){
  16. document.onmousedown=disableselect
  17. document.onclick=reEnable
  18. }
  19. </script>\
  20.  
I hope this helps.

Get the key/char codes of the keys pressed - this link should help. If they match, cancel them with a return false.

The code is pretty outdated. You could get rid of most of that code and it should work fine in most browsers.

Note that all this mouse/key disabling is easy to circumvent. Don't depend on it.

Whatever you do, the user will always be able to view the source of a page and, therefore, copy the content.

What exactly are you trying to achieve by blocking these keys and mouse events? If you're trying to protect the content, then forget it. It's not worth the effort and will easily be bypassed by someone willing enough.

If you're not going to abide by the rules, then the rules will be pointed out to you. It's not enough to read the rules, you also have to follow them.

Firstly, you're not my customer. I don't own this site and you're getting free help. Now I don't know if you took the wrong meaning from my post, but that was unintended. I was asking a genuine question and letting you know that your effort on this 'problem' might be wasted and put to better use elsewhere.

Let's say you got a fabulous script that does all the blocking. I can disable JavaScript and get all the content anyway. If not, I could view the source to see the content. All this mouse/key disabling/blocking will do is annoy your users.

Do you see where I'm coming from?

Even if you make all these efforts to stop someone getting at the source, they could just disable JavaScript. In fact, I suggest you try it. Go into your browser options and disable JavaScript and try loading the page again.

If you're still insistent, see post #5 to see how you could disable certain keys.
