I want to add a loading png in LiveSearch

I am using a plugin for live search .. everything is working fine .. i just want to add a loading png that appear on start of ajax request and disappear on results ..
please help me to customize the code just to add class where form id="search-kb-form" .. and remove the class when results are completed.
<form id="search-kb-form" class="search-kb-form" method="get" action="<?php echo home_url('/'); ?>" autocomplete="off">
<div class="wrapper-kb-fields">
<input type="text" id="s" name="s" placeholder="Search what you’re looking for" title="* Please enter a search term!">
<input type="submit" class="submit-button-kb" value="">
</div>
<div id="search-error-container"></div>
</form>
This is the plugin code
jQuery.fn.liveSearch = function (conf) {

add a background to the loading class
.loading {
background:url('http://path_to_your_picture');
}

How to replicate a typing effect using jQuery/JavaScript?

How to have the exact typing effect used on this page? https://www.braintreepayments.com/
<span class="writer" data-writer-command="['PayPal?', 'Apple Pay?', 'Venmo?', 'Bitcoin?']">Ve</span>

Here is the JSFiddle with the extracted library from the website : http://jsfiddle.net/8g6dsp0p/1/
You can initialize the script with this following code :
<span class="writer" data-writer-command="['PayPal?', 'Apple Pay?', 'Venmo?', 'Bitcoin?']"></span>
<script>
$(document).ready(function() {
new Writer
});
</script>

var word = "Venmo";
var cur = 1;
var intrvl = setInterval(function () {
$('.writer').html(word.slice(0,cur));
if(cur >= word.length) {
clearInterval(intrvl);
}
else{
cur++;
}
}, 500);
JSBin
The above jsBin has the code you require. it is not neatly formatted but code is correct.
Again to reproduce the code
<span clas="writer"></span>
var words = ["Venmo", "alright", "done", "ok"];
var curWord = 0;
function writeWord(word, deleteWord) {
var cur;
if(deleteWord){
cur = deleteWord.length;
var delIntrvl = setInterval(function () {
if(!cur) {
clearInterval(delIntrvl);
if(curWord < (words.length - 1)) {
writeWord(words[++curWord],"");
}
else {//if you dont need continous looping remove this else statement
curWord = 0;
writeWord(words[curWord],"");
}
}
else{
var reqWrd = deleteWord.slice(0,cur);
console.log(reqWrd);
$('.writer').html(reqWrd);
cur--;
}
}, 200);
}
else {
cur=1;
var intrvl = setInterval(function () {
if(cur >= word.length) {
clearInterval(intrvl);
writeWord("",word);
}
else{
var reqWrd = word.slice(0,cur);
console.log(reqWrd);
$('.writer').html(reqWrd);
cur++;
}
}, 200);
}
}
writeWord(words[curWord], "");
Updating the code and also providing jsBin for continous looping

JQuery: How to refactor JQuery interaction with interface?

The question is very simple but also a bit theoretical.
Let's imagine you have a long JQuery script which modifies and animate the graphics of the web site. It's objective is to handle the UI. The UI has to be responsive so the real need for this JQuery is to mix some state of visualization (sportlist visible / not visible) with some need due to Responsive UI.
Thinking from an MVC / AngularJS point of view. How should a programmer handle that?
How to refactor JS / JQuery code to implement separation of concerns described by MVC / AngularJS?
I provide an example of JQuery code to speak over something concrete.

My steps in such cases are:
First of all write (at least) one controller
Replace all eventhandler with ng-directives (ng-click most of all)
Pull the view state out of the controller with ng-style and ng-class. In most of all cases ng-show and ng-hide will be sufficed
If there is code that will be used more than once, consider writing a directive.
And code that has nothing todo with the view state - put the code in a service
write unit tests (i guess there is no one until now:) )

Unobtrusive date compare validator

So I've been following this tutorial here and it shows you how to validate dates compared with each other. I'm getting an error in the first block of code which I've commented and it says "Unable to get property 'element' of undefined or null reference" which originates from this line of code customValidation.formValidator = $(event.data.source).closest('form').data('validator') does anyone know of a work around for this so I don't get an error. I'm using the latest unobtrusive validation
window.customValidation = window.customValidation ||
{
relatedControlValidationCalled: function (event) {
if (!customValidation.activeValidator) {
customValidation.formValidator = $(event.data.source).closest('form').data('validator');
}
// code error below
customValidation.formValidator.element($(event.data.target));
},
relatedControlCollection: [],
formValidator: undefined,
addDependatControlValidaitonHandler: function (element, dependentPropertyName) {
var id = $(element).attr('id');
if ($.inArray(id, customValidation.relatedControlCollection) < 0) {
customValidation.relatedControlCollection.push(id);
$(element).on(
'blur',
{ source: $(element), target: $('#' + dependentPropertyName) },
customValidation.relatedControlValidationCalled);
}
}
};
adapter:
$.validator.unobtrusive.adapters.add('comparedates', ['otherpropertyname', 'allowequality'],
function (options) {
options.rules['comparedates'] = options.params;
if (options.message) {
options.messages['comparedates'] = options.message;
}
}
);
validator method:
$.validator.addMethod('comparedates', function (value, element, params) {
var otherFieldValue = $('input[name="' + params.otherpropertyname + '"]').val();
if (otherFieldValue && value) {
var currentValue = Date.parse(value);
var otherValue = Date.parse(otherFieldValue);
if ($(element).attr('name').toLowerCase().indexOf('begin') >= 0) {
if (params.allowequality) {
if (currentValue > otherValue) {
return false;
}
} else {
if (currentValue >= otherValue) {
return false;
}
}
} else {
if (params.allowequality) {
if (currentValue < otherValue) {
return false;
}
} else {
if (currentValue <= otherValue) {
return false;
}
}
}
}
customValidation.addDependatControlValidaitonHandler(element, params.otherpropertyname);
return true;
}, '');

Maybe you are loading this code too early, before the form is in the DOM. Make sure your code is protected by $(document).ready(your code here);

Packer jams everything onto one line if I'm not mistaken so that any missing semicolons that would have been originally parsed OK turn into hard errors.
There are a few missing semicolons in your js for example
return function(angle)
{
this._vimage.style.rotation=angle;
var radians=angle*Math.PI/180;
this._vimage.style.top= (this._img._heightMax - this._img.height)/2- (this._vimage.offsetHeight-this._img.height)/2 +"px";
this._vimage.style.left= (this._img._widthMax - this._img.width)/2- (this._vimage.offsetWidth-this._img.width)/2 +"px";
}
is missing a semicolon. there are more.

Here's a nice site which will tell you what is wrong with your javascript: http://jslint.com/
So paste your code there, click on the JSLint button and observe the errors and warnings you get. Once you fix them you may be confident that when packed your javascript will work.
