Wrote this for a JavaScript project I'm working on but when I run it It says Uncaught ReferenceError: checkAnswer is not defined, I'd really appreciate if anyone knew the problem. Thank you!
P.S. Don't know if the checkAnswer function has bugs or note becausa I couldn't test it out, I will when I can run it :)

First you need to bind this at the end of this function:
Startup.eventHandler2(document.getElementById(i), "onclick", function() {
this.checkAnswer(buttons[i], i)
}.bind(this));
Basically this tells the anonymous function "hey I want this to refer to this outer class, not the function itself".
(edited)

You need to either bind checkAnswer in the constructor like-so:
class Pairs extends Screen {
constructor() {
super();
var pair1 = null;
var nPair1;
var solution;
var rightCounter = 0;
var licao, nS;
this.checkAnswer = this.checkAnswer.bind(this);
}
Or use and arrow function which gives you the exact reference to the this checkAnswer like-so:
checkAnswer = (pair, nPair) => {
//your code goes here ...
}
This way you will be able to call this.checkAnswer inside the scope of your pairScreen function or wherever you want to call the function like #Davelunny point out

Linkedin Autoconnect With User role

I am trying to fix this script to automatically connect people you may know on Linkedin based on User roles (CEO e.t.c), Can someone help me fix this, Below is my code; I have tried the script on almost all browsers, Somebody help fix this.
var userRole = [
"CEO",
"CIO"
];
var inviter = {} || inviter;
inviter.userList = [];
inviter.className = 'button-secondary-small';
inviter.refresh = function () {
window.scrollTo(0, document.body.scrollHeight);
window.scrollTo(document.body.scrollHeight, 0);
window.scrollTo(0, document.body.scrollHeight);
};
inviter.initiate = function()
{
inviter.refresh();
var connectBtns = $(".button-secondary-small:visible");
//
if (connectBtns == null) {var connectBtns = inviter.initiate();}
return connectBtns;
};
inviter.invite = function () {
var connectBtns = inviter.initiate();
var buttonLength = connectBtns.length;
for (var i = 0; i < buttonLength; i++) {
if (connectBtns != null && connectBtns[i] != null) {inviter.handleRepeat(connectBtns[i]);}
//if there is a connect button and there is at least one that has not been pushed, repeat
if (i == buttonLength - 1) {
console.log("done: " + i);
inviter.refresh();
}
}
};
inviter.handleRepeat = function(button)
{
var nameValue = button.children[1].textContent
var name = nameValue.replace(/^\s\s*/, '').replace(/\s\s*$/, '');
function hasRole(role){
for(var i = 0; i < role.length; i++) {
// cannot read children of undefined
var position = button.parentNode.parentNode.children[1].children[1].children[0].children[3].textContent;
var formatedPosition = position.replace(/^\s\s*/, '').replace(/\s\s*$/, '');
var hasRole = formatedPosition.indexOf(role[i]) == -1 ? false : true;
console.log('Has role: ' + role[i] + ' -> ' + hasRole);
if (hasRole) {
return hasRole;
}
}
return false;
}
if(inviter.arrayContains(name))
{
console.log("canceled");
var cancel = button.parentNode.parentNode.children[0];
cancel.click();
}
else if (hasRole(userRole) == false) {
console.log("cancel");
var cancel = button.parentNode.parentNode.children[0];
cancel.click();
}
else if (button.textContent.indexOf("Connect")<0){
console.log("skipped");
inviter.userList.push(name); // it's likely that this person didn't join linkedin in the meantime, so we'll ignore them
var cancel = button.parentNode.parentNode.children[0];
cancel.click();
}
else {
console.log("added");
inviter.userList.push(name);
button.click();
}
};
inviter.arrayContains = function(item)
{
return (inviter.userList.indexOf(item) > -1);
};
inviter.usersJson = {};
inviter.loadResult = function()
{
var retrievedObject = localStorage.getItem('inviterList');
var temp = JSON.stringify(retrievedObject);
inviter.userList = JSON.parse(temp);
};
inviter.saveResult = function()
{
inviter.usersJson = JSON.stringify(inviter.userList);
localStorage.setItem('inviterList', inviter.usersJson);
};
setInterval(function () { inviter.invite(); }, 5000);
`
When I try executing this, I get the following error:
VM288:49 Uncaught TypeError: Cannot read property 'children' of undefined
at hasRole (<anonymous>:49:71)
at Object.inviter.handleRepeat (<anonymous>:66:11)
at Object.inviter.invite (<anonymous>:30:69)
at <anonymous>:108:35
Any ideas as to how to fix it?

How can I do to combine Confluence plugin with jQuery code?

[ERROR] Compilation produced 7 syntax errors.

The issue is that 'class' is a reserved word, and the YUI JavaScript compressor is complaining about it (and rightly so). You can fix this in your code here:
var item = $(this);
elemsDatas.push({
content: item.html(),
class: item.attr('class'),
href: item.attr('href'),
id: item.attr('id'),
colid: index % nbCols
});
by changing class: item.attr('class') to clazz: item.addr('class') or something similar--although then you'd have to adjust all of the other references that access this property too.
I believe you could also use 'class': item.addr('class') if you really wanted, but that makes it less convenient to access the property in the future.

Specific line having issues:
return console.error("Expose: this script should run at document-start")
UPDATE:
New issue. Uncaught SyntaxError: Illegal return statement engine.js:282
Lines 281-282 for debugging purposes:
if (!rules)
return console.error("Expose: cant find corresponding rule")
UPDATE 2:
This is my final issue. And this whole thing will be resolved.
It looks like its another return error. But i do not understand how to properly return this part.
Heres the error but its basically the same.
Uncaught SyntaxError: Illegal return statement engine.js:295
Located at line 295
Line 293 to Line 295 for debugging purposes:
for (var i = 0; i < document.head.childNodes.length; i++)
if (tryReplace(document.head.childNodes[i])){
return
}

here's a fix for the block of code that's causing the error
if (window.top == window.self) {
if (document.readyState !== 'loading') {
// don't return
console.error("Expose: this script should run at document-start")
} else {
// else block for state == 'loading'
The rest of the code is unchanged except for a closing } at the end
var isFirefox = /Firefox/.test(navigator.userAgent)
// Stage 1: Find corresponding rule
var rules
for (var i = 0; i < allRules.length; i++)
if (allRules[i].hostname.indexOf(window.location.hostname) !== -1) {
rules = allRules[i]
break
}
if (!rules)
return console.error("Expose: cant find corresponding rule")
// Stage 2: Search for `main_out.js`
if (isFirefox) {
function bse_listener(e) {
tryReplace(e.target, e)
}
window.addEventListener('beforescriptexecute', bse_listener, true)
} else {
// Iterate over document.head child elements and look for `main_out.js`
for (var i = 0; i < document.head.childNodes.length; i++)
if (tryReplace(document.head.childNodes[i]))
return
// If there are no desired element in document.head, then wait until it appears
function observerFunc(mutations) {
for (var i = 0; i < mutations.length; i++) {
var addedNodes = mutations[i].addedNodes
for (var j = 0; j < addedNodes.length; j++)
if (tryReplace(addedNodes[j]))
return observer.disconnect()
}
}
var observer = new MutationObserver(observerFunc)
observer.observe(document.head, {
childList: true
})
}
} // added this closing }
}

JS attribut-value onclick replace

I use codemirror and jquery to "simulate" an xml-editor in the browser. Some xml-Tags include an "on"-attribute with two possible values (true or false). Would it be possible to toggle these values at an onclick event? Is a codemirror/jquery plugin available?
EDIT :
self-coded solution.
function attrtoggle(){
var pos = editor.getCursor();
var line = editor.getLine(pos.line);
var index = line.indexOf("on=");
if(index > 0){
//define range
if ( pos.ch -3 < index || pos.ch - 9 > index)
return false;
var len = 10;
var replace_pos = index + 4;
if(line.charAt(replace_pos) == "t"){
//insert false
line = line.replace('true', 'false');
} else{
//insert true
line = line.replace('false', 'true');
}
edited = pos.line;
editor.setLine(pos.line, line);
}
}
Just add an event-handler for the onclick event
$(".CodeMirror").attr("onclick","javascript:attrtoggle()");

By far not perfect (bad design and so on) , but it works as expected:
Just trigger the function at an onclick event.
function attributeToggle(){
var transitions = {
"on": {
"false":"true",
"true":"false"
}
}
var pos = editor.getCursor(); // object {line, ch}
var token = editor.getTokenAt(pos);
var line = editor.getLine(pos.line);
try{
var prev_pos = token.start - 1;
var prev_token = editor.getTokenAt({'line':pos.line, 'ch':prev_pos});
if(prev_token.className == "attribute")
var attr = prev_token.string;
else
return false;
if(typeof transitions[attr] === "undefined") //nothing to replace
return false;
var current_val = token.string.toLowerCase().replace(/(['"])/g, "");
if(typeof transitions[attr][current_val] === "undefined")
return false;
var line_new = line.substring(0, token.start) + \
"\"" + transitions[attr][current_val] + "\"" + line.substring(token.end);
editor.setLine(pos.line, line_new);
} catch (e){
console.log(e);
}
}
