chatbox java doesnt work

So i tried adding some java code i found here but it doenst do anything.
Im a doing something wrong ?
there are 2 codes :

$(window).load(function() {
var chatbox_script = function() {
var overrided = Chatbox.prototype.refresh;
Chatbox.prototype.refresh = function(data) {
overrided.call(this, data);
$('.chatbox-username').each(function(){
this.previousSibling&&$.trim(this.previousSibling.nodeValue)=="@"&&$(this.previousSibling).replaceWith('<img src="https://i.imgur.com/zICIAne.png" /> ')
})
};
};
var s=document.createElement('script');s.text="("+chatbox_script.toString()+")();";$('object[data^="/chatbox/index.forum"],iframe[src^="/chatbox/index.forum"]').each(function(){try{$(this.contentDocument||this.contentWindow.document).find("#chatbox").closest("html").find("head").first().each(function(){this.appendChild(s.cloneNode(true))})}catch(a){}})
});




And :

$(window).load(function() {
var chatbox_script = function() {
$('#chatbox > p > .msg > span').filter('[style="color"],[style="color"]').closest('p').remove();
var overrided = Chatbox.prototype.refresh;
Chatbox.prototype.refresh = function(data) {
if (data.messages && data.messages.length) {
data.messages = $.grep(data.messages, function(v) {
return v.userId != -10 || $.inArray(v.msgColor, ["red", "green"]) == -1;
});
}
overrided.call(this, data);
};
};

var
s=document.createElement('script');s.text="("+chatbox_script.toString()+")();";$('object[data^="/chatbox/index.forum"],iframe[src^="/chatbox/index.forum"]').each(function(){try{$(this.contentDocument||this.contentWindow.document).find("#chatbox").closest("html").find("head").first().each(function(){this.appendChild(s.cloneNode(true))})}catch(a){}})
});


They are the crown replace for @
and the login / logout removal
