jQuery reset star-rating.js

I am using this plugin https://danielupshaw.com/jquery-star-rating/
I want to reset my form. But how can I reset these stars??
$("#btn-reset").on('click', function() {
//some other inputs reset
$('#starrating').star_rating.remove();
$('#starrating').star_rating.reload();
}
Please help on how to reset these stars to zero or null.
Here is the full code.
$("#btn-reset").on('click', function() {
$('#starrating').star_rating.reload();
});
jQuery(function($) {
$('#starrating').star_rating({
click: function(clicked_rating, event) {
event.preventDefault();
$('input[name=\'rating\']').val(clicked_rating);
this.rating(clicked_rating);
}
});
});

I don't know if this is the best approach, since I'm not familiar with this library...
But I achieved a reset like this:
$(document).ready(function(){
$('.rating').star_rating();
$("#resetStars").on("click",function(){
$(".rating").remove();
$('.star-rating').replaceWith("<span class='rating'>0/10 stars</span>");
$(".rating").text("0/10").star_rating();
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<link href="//maxcdn.bootstrapcdn.com/font-awesome/4.3.0/css/font-awesome.min.css" rel="stylesheet"/>
<script src="https://danielupshaw.com/jquery-star-rating/jquery.star-rating.js"></script>
<h1>This is a good script!</h1>
<span class="rating">9.5/10 stars</span><br>
<br>
<br>
<button id="resetStars">Reset stars</button>

I'm not familiar with the plugin, but looking at the link you provided, can't you just update the text inside of the element to reflect an empty or zero rating? Something like:
$("#btn-reset").on('click', function() {
$('#starrating').text('0/5').star_rating();
}

It looks like all you need to do is set the content to 0. Then re initialize the method.
$("#starrating").html("0");
$("#starrating").star_rating();

You could try something like this; an attempt to set default blank stars on initial page load, or Click.
$(document).ready(function() {
$('i').addClass('fa-star-o');
});
Then refresh page to rest:
$( ".reset" ).click(function() {
location.reload();
});
If you don't want to refresh page, you could try:
$( ".reset" ).click(function() {
$('i').addClass('fa-star-o');
});
You may have to re-initiate your click feature on the star with similar jQuery to re add the appropriate Class when needed.
If this doesn't help or work; could you create a https://jsfiddle.net/ to fully replicate your issue; and then we could solve it. If it were me; I'd find a better plugin to use or just write it from scratch at that point.

A bit another approach by re-rendering your rating stars from scratch using custom renderRating function.
HTML:
<div class="rating-stars"></div>
<button class="reset-rating">Reset rating</button>
JS:
var defaultRating = "0/5";
renderRating("3/5");
function renderRating(rating) {
var ratingEl = $('<span />').addClass('rating');
var ratingStr = rating || defaultRating;
ratingEl.text(ratingStr);
$('.rating-stars').html(ratingEl);
ratingEl.star_rating();
}
$('.reset-rating').on('click', function() {
renderRating();
})
Preview on JSFiddle

This should reset it to 0:
$('#starrating').star_rating('rating', 0);
Here's the format to call the public methods:
$('#starrating').star_rating('method_name');
Should your click event be inside the document ready? If it is outside document ready, that can sometimes cause issue. I hope this helps :)

Click visible button in protractor?

I have a page which looks something like this. It's a wizard with steps. Depending on the "step" scope variable, a different part of the wizard is shown:
<div ng-show="step == 'first'">
<button>Next</button>
</div>
<div ng-show="step == 'second'">
<button>Next</button>
</div>
<div ng-show="step == 'third'">
<button>Next</button>
</div>
To click the next button I run into problems though. Because there are three of them. The following code returns all of them:
var next = element(by.buttonText('Next'));
And doing:
next.click();
will click the first one. How can I find the visible button only, and click that one?

First I was confused by isDisplayed returning a promise. This function is what I came up with:
function clickButton(text) {
var buttons = element.all(by.buttonText(text));
buttons.each(function(button) {
button.isDisplayed().then(function(isVisible) {
if (isVisible) {
button.click();
}
})
});
}
Which can be used like this:
clickButton('next');

Here is a bit more cleaner version in terms of understanding that uses filter() to filter a single visible button and click it:
function clickButton(text) {
var buttons = element.all(by.buttonText(text));
var visibleButton = buttons.filter(function(button) {
return button.isDisplayed().then(function(isVisible) {
return isVisible;
});
}).first();
visibleButton.click();
}
As a bonus, you'll also get an error if there are no visible buttons found, as opposed to your current approach which would not fail in this case.

You should be able to chain the elements to specify which next button you want to click.
var firstNext = element(by.css('div[ng-show="step == \'first\'"]')).element(by.buttonText('Next'));
var secondNext = element(by.css('div[ng-show="step == \'second\'"]')).element(by.buttonText('Next'));
var thirdNext = element(by.css('div[ng-show="step == \'third\'"]')).element(by.buttonText('Next'));
// We are on the first step
firstNext.click();
// We are on the second step
secondNext.click();
// We are on the third step
thirdNext.click();

Javascript: Photo Gallery with Forward/Back Button

I'm super new to Javascript and trying to make a front and back button to move through a set of images.Below is what I'm doing but it just wont' work. I added an alert to the beginning of both functions and they worked so I know the functions are being called.
Please help!
HTML:
Javascript:
var which=0;
var photos=new Array();
photos[0]='images/gallery/airport.jpg';
photos[1]='images/gallery/vancouvercenter.jpg';
photos[2]='images/gallery/translatorjudges.jpg';
photos[3]='images/gallery/emmaplaying.jpg';
photos[4]='images/gallery/kate.jpg';
photos[5]='images/gallery/plushies.jpg';
photos[6]='images/gallery/juniors.jpg';
photos[7]='images/gallery/pikachucamera.jpg';
photos[8]='images/gallery/dressup.jpg';
photos[9]='images/gallery/sandiego.jpg';
photos[10]='images/gallery/signedbox.jpg';
photos[11]='images/gallery/top42013.jpg';
photos[12]='images/gallery/5.JPG';
photos[13]='images/gallery/airportplay.jpg';
photos[14]='images/gallery/piplup.jpg';
photos[15]='images/gallery/2.JPG';
photos[16]='images/gallery/booze.jpg';
photos[17]='images/gallery/dice.jpg';
photos[18]='images/gallery/akinator.jpg';
photos[19]='images/gallery/sleeping.jpg';
function backward(){
if (which>0){
which=which-1;
}
document.GetElementbyId("gallery").src=photos[which];
}
function forward(){
if (which<photos.length-1)
{
which=which+1;
}
document.GetElementbyId("gallery").src=photos[which];
}

Might be as simple as changing GetElementById to getElementById

Javascript function changeImage: Issues using variables for getElementById or getElementsByName

I'm having some trouble getting my code to do what I want. I have multiple sections that I have set to toggle show/hide, and it functions correctly. However, I'm now trying to switch the images to where instead of always being static with "More," I'd like it to switch to "Less" when it's expanded.
It does work... but only for the first one. If I press the buttons on any of the others, it only changes just the first one. You can see the page here:
http://jfaq.us
I've tried several different solutions with variables, but I can't seem to get it to work.
Help? Thanks in advance!
function changeImage() {
if (document.getElementById("moreorless").src == "http://jfaq.us/more.png")
{
document.getElementById("moreorless").src = "http://jfaq.us/less.png";
}
else
{
document.getElementById("moreorless").src = "http://jfaq.us/more.png";
}
}
function toggleMe(a){
var e=document.getElementById(a);
if(!e)return true;
if(e.style.display=="none")
{
e.style.display="block"
}
else{
e.style.display="none"
}
return true;
}

The id attribute must be unique. That's why it's not working. Also, it's not a good idea to use inline event handlers like you are doing, you should register event handlers using addEventListener instead.
Without changing all your code, one thing you can do is pass a reference to the currently clicked element to the changeImage function.
function changeImage(el) {
var moreUrl = 'http://jfaq.us/more.png';
el.src = el.src === moreUrl? 'http://jfaq.us/less.png' : moreUrl;
}
Then change the inline handler for onclick="changeImage(this);"

You are using same Id for all inputs. This is causing the problem.
Give every element a unique Id.
If you want to perform grp operation use jquery class.

That's because you use the same id for the both images, and getElementById apparently takes the first one.
Here is the updated code:
html:
<input type="image" src="http://jfaq.us/more.png" id="moreorless" onclick="changeImage.call(this);return toggleMe('para3')" >
script:
// inside the event handler 'this' refers to the element clicked
function changeImage() {
if (this.src == "http://jfaq.us/more.png") {
this.src = "http://jfaq.us/less.png";
} else {
this.src = "http://jfaq.us/more.png";
}
}

check this
http://jsfiddle.net/Asb5A/3/
function changeImage(ele) {
if (ele.src == "http://jfaq.us/more.png")
{
ele.src = "http://jfaq.us/less.png";
}
else
{
ele.src = "http://jfaq.us/more.png";
}
}
<input type="image" src="http://jfaq.us/more.png" onclick="changeImage(this);return toggleMe('para3')" >

hide one div when another is showing in jQuery?

I am trying to hide a div when another one is visible.
I have div 1 and div 2.
If div 2 is showing then div 1 should hide and if div 2 is not showing then div 1 should be visible/unhide.
The function would need to be function/document ready upon page load.
I've tried this but I'm not having any luck, can someone please show me how I can do this.
<script>
window.onLoad(function () {
if ($('.div2').is(":visible")) {
$(".div1").fadeOut(fast);
} else if ($('.div2').is(":hidden")) {
$('.div1').fadeIn(fast);
}
});
</script>

Add a class of hidden to each div, then toggle between that class using jQuery. By the way, window.onload is not a function, it expects a string like window.onload = function() {}. Also, put fast in quotations. I don't know if that's required, but that's how jQuery says to do it.
<div class="div1"></div>
<div class="div2 hidden"></div>
.hidden { display: none }
$(document).ready(function() {
if($(".div1").hasClass("hidden")) {
$(".div2").fadeIn("fast");
}
else if($(".div2").hasClass("hidden")) {
$(".div1").fadeIn("fast");
}
});

You should pass a string to the .fadeIn() and .fadeOut() methods.
Instead of .fadeIn(fast) it'll be .fadeIn("fast"). Same for .fadeOut().
And in general since you're already using jQuery it's better to wrap your code like this:
$(function () {
// Code goes here
});

It looks like you're using jquery selectors (a javascript library). If you're going to use jquery make sure the library is loaded properly by including it in the document header (google makes this easy by hosting it for you <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>)
With jQuery loaded you can do it like this
$(document).ready(function(){
if ($('.div1').is(":visible")) {
$('div2').hide();
}
else if ($('.div2').is(":visible")) {
$('div1').hide();
}
});
WORKING EXAMPLE: http://jsfiddle.net/HVDHC/ - just change display:none from div 2 to div 1 and click 'run' to see it alternate.

You can use setTimeout or setInterval to track if these divs exists
$(function() {
var interval = window.setInterval(function() {
if($('#div2').hasClass('showing')) {
$('#div1').fadeOut('fast');
}
if($('#div2').hasClass('hidden')) {
$('#div1').fadeIn('fast');
}
}, 100);
// when some time u don't want to track it
// window.clearInterval(interval)
})
for better performance
var div1 = $('#div1')
, div2 = $('#div2')
var interval ....
// same as pre code
