Opera can use greasemonkey scripts. Here's directions how to use javascript in Opera - http://my.opera.com/Contrid/blog/2007/02/11/how-to-greasemonkey-in-opera
I suggest you use this, though:
| Code: |
(function() {
// Get stored hidden users from cookie
var users = [];
var cookieName = "phpUserHide";
for (var i = 0; i < document.cookie.split('; ').length; i++) {
var oneCookie = document.cookie.split('; ')[i].split('=');
if (oneCookie[0] == cookieName) {
users = oneCookie[1].split(', ');
break;
}
}
// Cursor functions
var curPointer = function(event) {
event.target.style.cursor = 'pointer';
event.preventDefault();
};
var curDefault = function(event) {
event.target.style.cursor = 'default';
event.preventDefault();
};
// Add or remove a user from the cookie
var addRemoveUser = function(event) {
// Parse current cookie
for(j = 0; j < document.cookie.split('; ').length; j++ ) {
var oneCookie = document.cookie.split('; ')[j].split('=');
if (oneCookie[0] == cookieName) {
users = oneCookie[1].split(', ');
break;
}
}
var user = escape(event.target.nextSibling.innerHTML)
notFound = true;
for (var j = 0; j < users.length; j++) {
if (users[j] == user) {
users.splice(j, 1);
notFound = false;
}
}
if (notFound)
users.push(user);
if (users.length > 0) {
var date = new Date();
var days = 365;
date.setTime(date.getTime() + (days*24*60*60*1000));
var expires = '; expires=' + date.toGMTString();
var value = users.join(', ');
document.cookie = cookieName + '=' + value + expires + '; path=/';
} else {
document.cookie = cookieName + '=;expires=Thu, 01-Jan-1970 00:00:01 GMT; path=/';
}
window.alert(unescape(user) + ' has been ' + (notFound ? 'added to' : 'removed from')
+ ' your hide list\n'
+ 'You must refresh the page to view the changes.');
event.preventDefault();
};
// Toggle display of user's post
var togglePost = function(event) {
var displayState = event.target.getAttribute('displaystate');
if (displayState == 'none')
displayState = '';
else
displayState = 'none';
event.target.setAttribute('displaystate', displayState);
containingRow = event.target.parentNode.parentNode;
var innerTags = containingRow.getElementsByTagName('*');
for (var i = 0; i < innerTags.length; i++) {
var tagClass = innerTags[i].getAttribute('class');
if (tagClass == 'postbody' || tagClass == 'postsig'
|| tagClass == 'postdetails' || innerTags[i].tagName == 'TABLE')
innerTags[i].style.display = displayState;
}
event.preventDefault();
};
// Toggle display of user's quote
var toggleQuote = function(event) {
var displayState = event.target.getAttribute('displaystate');
if (displayState == 'none')
displayState = 'table-row';
else
displayState = 'none';
event.target.setAttribute('displaystate', displayState);
// Jump to parent row
var containingRow = event.target.parentNode.parentNode.parentNode.parentNode.nextSibling;
// Find containing row
while (containingRow.nodeType != 1)
containingRow = containingRow.nextSibling;
containingRow.style.display = displayState;
event.preventDefault();
};
// Find all the usernames in the page
var results = document.evaluate("//span[@class='name']/b|//span[@class='name']/strong", document, null,
XPathResult.ANY_TYPE, null);
var resultNodes = [];
var aResult;
while (aResult = results.iterateNext())

}
}

resultNodes[i].parentNode.insertBefore(toggler, resultNodes[i]);
// If this user isn't in our hide list, skip to the next user
if (notFound)
continue;
// Find the first element node (td) in the containing row
var elem = containingRow.firstChild;
while (elem.nodeType != 1)
elem = elem.nextSibling;
// Create a span to control toggling

while (containingRow.nodeType != 1)
containingRow = containingRow.nextSibling;
// Find username
var usermatch = resultNodes[i].innerHTML.match(/(.*) wrote:$/);
if (usermatch)
var user = escape(usermatch[1]);
else
continue;
// Flag whether the user is in our hide list
var notFound = true;
for (var j = 0; j < users.length; j++) {
if (users[j] == user) {
notFound = false;

Copy the text, open notepad, save it to a file named whatever.user.js in the folder you directed Opera to for JavaScript.
I tried using Dimitry's script, but it was throwing up errors. |
