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

I try to create a Confluence plugin with below js file(Text 1), but the Confluence console said below error(Text 2), could anyone please help me to resolve this problem?
I wonder if the jQuery code should begin with follow:
AJS.toInit(function() {
AJS.$(document).ready(function() {
【Text 1】
(function ($) {
$.fn.jaliswall = function (options) {
this.each(function () {
var defaults = {
item: '.wall-item',
columnClass: '.wall-column',
resize: false
}
var prm = $.extend(defaults, options);
var container = $(this);
var items = container.find(prm.item);
var elemsDatas = [];
var columns = [];
var nbCols = getNbCols();
init();
function init() {
nbCols = getNbCols();
recordAndRemove();
print();
if (prm.resize) {
$(window).resize(function () {
if (nbCols != getNbCols()) {
nbCols = getNbCols();
setColPos();
print();
}
});
}
}
function getNbCols() {
var instanceForCompute = false;
if (container.find(prm.columnClass).length == 0) {
instanceForCompute = true;
container.append("<div class='" + parseSelector(prm.columnClass) + "'></div>");
}
var colWidth = container.find(prm.columnClass).outerWidth(true);
var wallWidth = container.innerWidth();
if (instanceForCompute) container.find(prm.columnClass).remove();
return Math.round(wallWidth / colWidth);
}
// save items content and params and removes originals items
function recordAndRemove() {
items.each(function (index) {
var item = $(this);
elemsDatas.push({
content: item.html(),
class: item.attr('class'),
href: item.attr('href'),
id: item.attr('id'),
colid: index % nbCols
});
item.remove();
});
}
//determines in which column an item should be
function setColPos() {
for (var i in elemsDatas) {
elemsDatas[i].colid = i % nbCols;
}
}
// to get a class name without the selector
function parseSelector(selector) {
return selector.slice(1, selector.length);
}
//write and append html
function print() {
var tree = '';
//creates columns
for (var i = 0; i < nbCols; i++) {
tree += "<div class='" + parseSelector(prm.columnClass) + "'></div>";
}
container.html(tree);
// creates items
for (var i in elemsDatas) {
var html = '';
var content = (elemsDatas[i].content != undefined) ? elemsDatas[i].content : '';

}
}
//creates a well-formed attribute

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.

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.

else if (module.location === 'bp2') href = ubnav.linkModuleBaseBP2;
else if (module.location === 'meteor') href = ubnav.linkModuleBaseMeteor;
href += (module.suffixPath) ? module.suffixPath : module.name;
}
var current = (ubnav.currentModule === module.name) ? ' class="active"' : '';
$parent.append('<li' + current + '>' + module.title + '</li>');
}

You have typed insertModule($parent, module) but your function is called insertModules()
Same with: insertModule($currentModuleParent, module);

I isolated and solved the problem.
It was a bootstrap.min.js file that was included too much.

},
At the end of my second function I am displaying the result $(a).html(info);
where as info contains different element based on the calculations.Default info is set to CLOSED which is defined in another file as var closed = "CLOSED".
I am expecting the table should display string CLOSED when all the different conditions are invalid. Both .text() and .html() method works fine on FF but not on Chrome as explained in the beginning.

How would I apply this onbeforeload function to this javascript?

I've been trying to add this onbeforeload script to the following script, but I haven't been able to get it to work.
Could someone show me how to add it correctly?
This is the onbeforeload code -
(function($) {
$(window).load(function () {
// retrieved this line of code from http://dimsemenov.com/plugins/magnific-popup/documentation.html#api
$.magnificPopup.open({
items: {
src: 'someimage.jpg'
},
type: 'image'
// You may add options here, they're exactly the same as for $.fn.magnificPopup call
// Note that some settings that rely on click event (like disableOn or midClick) will not work here
}, 0);
});
})(jQuery);
Here's the script I'm trying to add it to -

How to add/remove a class in JavaScript?

Since element.classList is not supported in IE 9 and Safari-5, what's an alternative cross-browser solution?
No-frameworks please.
Solution must work in at least IE 9, Safari 5, FireFox 4, Opera 11.5, and Chrome.
Related posts (but does not contain solution):

Add remove class?

Here is solution for addClass, removeClass, hasClass in pure javascript solution.
Actually it's from http://jaketrent.com/post/addremove-classes-raw-javascript/
function hasClass(ele,cls) {
return !!ele.className.match(new RegExp('(\\s|^)'+cls+'(\\s|$)'));
}
function addClass(ele,cls) {
if (!hasClass(ele,cls)) ele.className += " "+cls;
}
function removeClass(ele,cls) {
if (hasClass(ele,cls)) {
var reg = new RegExp('(\\s|^)'+cls+'(\\s|$)');
ele.className=ele.className.replace(reg,' ');
}
}

Look at these oneliners:
Remove class:
element.classList.remove('hidden');
Add class (will not add it twice if already present):
element.classList.add('hidden');
Toggle class (adds the class if it's not already present and removes it if it is)
element.classList.toggle('hidden');
That's all! I made a test - 10000 iterations. 0.8s.

I just wrote these up:
function addClass(el, classNameToAdd){
el.className += ' ' + classNameToAdd;
}
function removeClass(el, classNameToRemove){
var elClass = ' ' + el.className + ' ';
while(elClass.indexOf(' ' + classNameToRemove + ' ') !== -1){
elClass = elClass.replace(' ' + classNameToRemove + ' ', '');
}
el.className = elClass;
}
I think they'll work in all browsers.

The simplest is element.classList which has remove(name), add(name), toggle(name), and contains(name) methods and is now supported by all major browsers.
For older browsers you change element.className. Here are two helper:
function addClass(element, className){
element.className += ' ' + className;
}
function removeClass(element, className) {
element.className = element.className.replace(
new RegExp('( |^)' + className + '( |$)', 'g'), ' ').trim();
}

One way to play around with classes without frameworks/libraries would be using the property Element.className, which "gets and sets the value of the class attribute of the specified element." (from the MDN documentation).
As #matías-fidemraizer already mentioned in his answer, once you get the string of classes for your element you can use any methods associated with strings to modify it.
Here's an example:
Assuming you have a div with the ID "myDiv" and that you want to add to it the class "main__section" when the user clicks on it,
window.onload = init;
function init() {
document.getElementById("myDiv").onclick = addMyClass;
}
function addMyClass() {
var classString = this.className; // returns the string of all the classes for myDiv
var newClass = classString.concat(" main__section"); // Adds the class "main__section" to the string (notice the leading space)
this.className = newClass; // sets className to the new string
}

Read this Mozilla Developer Network article:
https://developer.mozilla.org/en/DOM/element.className
Since element.className property is of type string, you can use regular String object functions found in any JavaScript implementation:
If you want to add a class, first use String.indexOf in order to check if class is present in className. If it's not present, just concatenate a blank character and the new class name to this property. If it's present, do nothing.
If you want to remove a class, just use String.replace, replacing "[className]" with an empty string. Finally use String.trim to remove blank characters at the start and end of element.className.

Fixed the solution from #Paulpro
Do not use "class", as it is a reserved word
removeClass function
was broken, as it bugged out after repeated use.
`
function addClass(el, newClassName){
el.className += ' ' + newClassName;
}
function removeClass(el, removeClassName){
var elClass = el.className;
while(elClass.indexOf(removeClassName) != -1) {
elClass = elClass.replace(removeClassName, '');
elClass = elClass.trim();
}
el.className = elClass;
}

The solution is to
Shim .classList:
Either use the DOM-shim or use Eli Grey's shim below

Improved version of emil's code (with trim())
function hasClass(ele,cls) {
return !!ele.className.match(new RegExp('(\\s|^)'+cls+'(\\s|$)'));
}
function addClass(ele,cls) {
if (!hasClass(ele,cls)) ele.className = ele.className.trim() + " " + cls;
}
function removeClass(ele,cls) {
if (hasClass(ele,cls)) {
var reg = new RegExp('(\\s|^)'+cls+'(\\s|$)');
ele.className = ele.className.replace(reg,' ');
ele.className = ele.className.trim();
}
}

function addClass(element, classString) {
element.className = element
.className
.split(' ')
.filter(function (name) { return name !== classString; })
.concat(classString)
.join(' ');
}
function removeClass(element, classString) {
element.className = element
.className
.split(' ')
.filter(function (name) { return name !== classString; })
.join(' ');
}

Just in case if anyone would like to have prototype functions built for elements, this is what I use when I need to manipulate classes of different objects:
Element.prototype.addClass = function (classToAdd) {
var classes = this.className.split(' ')
if (classes.indexOf(classToAdd) === -1) classes.push(classToAdd)
this.className = classes.join(' ')
}
Element.prototype.removeClass = function (classToRemove) {
var classes = this.className.split(' ')
var idx =classes.indexOf(classToRemove)
if (idx !== -1) classes.splice(idx,1)
this.className = classes.join(' ')
}
Use them like:
document.body.addClass('whatever') or document.body.removeClass('whatever')
Instead of body you can also use any other element (div, span, you name it)

add css classes: cssClassesStr += cssClassName;
remove css classes: cssClassStr = cssClassStr.replace(cssClassName,"");
add attribute 'Classes': object.setAttribute("class", ""); //pure addition of this attribute
remove attribute: object.removeAttribute("class");

A easy to understand way:
// Add class
DOMElement.className += " one";
// Example:
// var el = document.body;
// el.className += " two"
// Remove class
function removeDOMClass(element, className) {
var oldClasses = element.className,
oldClassesArray = oldClasses.split(" "),
newClassesArray = [],
newClasses;
// Sort
var currentClassChecked,
i;
for ( i = 0; i < oldClassesArray.length; i++ ) {
// Specified class will not be added in the new array
currentClassChecked = oldClassesArray[i];
if( currentClassChecked !== className ) {
newClassesArray.push(currentClassChecked);
}
}
// Order
newClasses = newClassesArray.join(" ");
// Apply
element.className = newClasses;
return element;
}
// Example:
// var el = document.body;
// removeDOMClass(el, "two")
