No right-click: Web site owners often would like to protect their images or other content, but can't do it effectivelly. The following script can provide protection only against people who are not very familiar with their browser, but at least it's some kind of content-protection and it's very simple. The script that disables the right-click on a page goes like this (put in <head> section) :
<script>
function norightclick(){
if(event.button==2){
alert('Your text here.')}}
document.onmousedown=norightclick
</script>
Right-click on this page to see an example.
Blocking JavaScript errors: On a page with external content (automated news, ad banners etc) you can often notice in the status bar a notification about a JavaScript error. The next script can help prevent the display of such an error notification:
<script>
function noErrors() { return true;}
window.onerror = noErrors;
</script>
Place the script as the first script in the <head> section of the HTML document.
Display and hide content: The next script demonstrates how to display or hide content on a page:
<script>
function nes(yt){
if(yt.style.display == "none"){
yt.style.display=""
}else{
yt.style.display="none"}}</script>
The content has to be here inside the span element with the id 'yt'.
<div onclick="nes(yt)">Click here to see</div><span id=yt style="display:none;color: red;border:1 maroon solid">The content goes here</span>
Show example The content goes here
Next: The window
