I need to create a simple button made only of an image, and which will open a JQuery Dialog when the user clicks on it.
I am doing some reading and notice many solutions: <button>, <image> with a <a>, using CSS to modify a button background, etc...
This is confusing, what is the proper way to implement my image button?
Thanks.
P.S.: The button/image should be focussable. An operational JSFiddle example is welcome.
The proper way largely depends on what the button will do if JavaScript is not available.
If you are going to submit a form then:
<button> <img src="..." alt="..."> </button>
If you are going to go to a URL then:
<img src="..." alt="...">
If you are going to do absolutely nothing (generally not a good idea, you should follow the principles of Progressive Enhancement and Unobtrusive JavaScript, but acceptable if you only generate the button with JavaScript in the first place and the loss to the user is convenience rather then essential functionality):
<button type="button"> <img src="..." alt="..."> </button>
You then bind the JavaScript to either the form's submit event, or the button/anchor's click event and prevent the default behaviour so the form won't be submitted / the link won't be followed if the JavaScript executes successfully.
Create a button and put background-image for it.

I found the solution after many struggles: http://jsfiddle.net/YRY8M/3/.
<html>
<head></head>
<body>
<input type="image" tabindex="0" onclick="doSomething()" src="http://upload.wikimedia.org/wikipedia/commons/thumb/0/0c/White_and_yellow_flower.JPG/320px-White_and_yellow_flower.JPG"
/>
<br />
<button tabindex="1">I am focussable too !!!</button>
</body>
</html>
And some javascript:
function doSomething() {
alert('Hello!');
}
It depends on what you want to do in every case. There is no guideline that says "you should do it like this", but there are situations that some cases are more suitable than others.
For example according to this review, IE versions of 8 and below have some buggy behaviour regarding <button> tag when trying to use it as a submit button.
Ηowever the <button> has some new attributes added in HTML5 which you can see here , ammong them is autofocus and other useful that will be supported by most modern major browsers.
In your case that you want to maintain the "focus" (i assume with tabbing support), if you use a single <image> as a button (with or without <a>), you will have to add some JS code to make the image focusable when the appropriate tab is pressed. So you will have to write a bit more code to do the same thing.
There is one more solution which might be suitable for you, since you do not need to submit the form to server side. Using the <input type="image" type and defining the src attribute inside it, will be focusable and not require neither any JS code to run nor any difficult CSS. You can find more about it's syntax here
So, it ends up to you to decide which one of all them to use.
I would use the one that i find more flexible, easier for me to code, easily reusable and is supported by most of my target browsers.
Use jQuery as you own it...
<html>
<head>
<script src="http://code.jquery.com/jquery-1.8.3.js"></script>
<style type="text/css">
#theBtn{
margin: 20% auto 0;
background: url('http://upload.wikimedia.org/wikipedia/commons/thumb/0/0c/White_and_yellow_flower.JPG/320px-White_and_yellow_flower.JPG');
width: 100px;
height: 50px;
}
</style>
</head>
<body>
<div id="theBtn"></div>
<script type="text/javascript">
$(document).ready(function(){
$("#theBtn").click(function(){
if(confirm('Are you sure?')){
$("#theBtn").fadeOut('slow');
}
});
});
</script>
</body>
</html>
Inside a <button> tag , put your image, and attach an click event to <button> to open the dialog on click.
JSFiddle
First thing, There is either an image or a button. But not both.
I would say, create an image and place your code in the onclick() function of that image.
var img= $("#my-image-id");
image.click(function() {
// your code here
}
As I know You can't change the look of the Safari buttons thats why I suggest to use a for the solution. Here is my simple code: http://jsfiddle.net/djgBK/1/
The basis is:
Take an a element put the link content to the left,
Then replace it with image that is actualy it's background. Becouse it's a element user can select it usin only TAB button.
What's more using an a elemet will let You to put title which will be displayed after hovering/entering over the button.

Here is the "submit" button in the form with no onclick attribute.
<div id="243c0bb6-584e-4d48-a8fa-4308cd632028" class="nike-unite-submit-button joinSubmit nike-unite-component blurred">
<input id="d7e56d05-36e1-42f7-922b-d2979375007a" type="button" value="CREATE ACCOUNT">

I am more confused about the <form> tags from the Nike website source:
<form id="nike-unite-joinForm" class="nike-unite-form" method="post"
action="javascript:;" onsubmit="return false;">
...
</form>
How do I find out what is happening when I actually click the button on the page?
Using mouse-click breakpoints in chrome dev tools gives me a plethora of JavaScript functions takes too long for me to parse through.
If there are attributes or listeners added to the ID (such as a link to a script), I could not find them after using "Command-F" on the different attributes of the form.
The only other clue which I am not sure how to purse is that method="post".
I understand that all websites are different, but my question is a general one:
How do I figure out what the script that is being run when I click on the form?
Thanks in advance.
Try this:
document.getElementById('nike-unite-joinForm').submit();
This is from w3schools.com:
https://www.w3schools.com/jsref/met_form_submit.asp
EDIT:
Ok, I tried it myself on the registration website and it didn't work. Experimenting a bit with it I noticed an apparently random id is assigned to the DOM-Elements.
But I've found a solution:
document.getElementsByClassName("nike-unite-submit-button joinSubmit nike-unite-component")[0].children[0].click();
This works because the div in which the submit button is has a unique set of classes. So I get the first (and only) Element with this classes, and apply .click() to the first child element
Perhaps you could try to change submit with click:
document.getElementById('nike-unite-joinForm').click()
I've been rummaging through the web to how to click buttons for a project I'm working on with Javascript+JQuery(Still not very good). Luckily I was able to find my answer and figured out how to click basic HTML buttons that looked like this(Cut off some of the code just to get the point across).
<div class="ui-block-a">
<input type="submit" value="Buy Now" data-theme="d">
</div>
But now I've come across a button like this.
<div id="BuyWithRobux">
<div data-expected-currency="1" data-asset-type="T-Shirt" class="btn-primary btn-medium PurchaseButton " data-se="item-buyforrobux" data-item-name="Donations" data-item-id="170938328" data-expected-price="2" data-product-id="20832770" data-expected-seller-id="180359" data-bc-requirement="0" data-seller-name="Clone3102">
Buy with R$
<span class="btn-text">Buy with R$</span>
</div>
</div>
Just based off of what I know I don't think I can use what I used to click the last button which was...
$("input[type='submit']").click();
So my question is how can I click this "button"? I've tried using my old code on it to no avail. I rather not use Selenium, or anything if at all possible. Could anyone help me out with this? If you need anymore information just say what and I'll do my best to provide it, fairly new to this so don't know what to include sadly.
Thank you in advance.
By "clicking this button" If you meant to trigger a click on div#BuyWithRobux , You can do so like
$("#BuyWithRobux").click();
or
$("#BuyWithRobux").trigger("click");
The syntax for triggering a click remains the same, all you've to do is to use the right selector to target the element on which you need to trigger the event.

This is sort of a condensed version of the code, the real version is too long to post but this is enough to represent the concept. I am using this to switch guitar diagrams based on several choices represented by anchors with the corresponding id in the href="". After spending several days getting it to work just right on a static html page, the script won't work in a Wordpress page which is where I intend to use it. I have tried it with the script in the head or inline (which shouldn't matter) - but either way it will not function. I know that Wordpress and certain plugins use Jquery so there may be a version mismatch causing conflicts. I am not (yet) an expert in javascript but I know there are several ways to skin a cat as the saying goes, I just need to find one that plays nice with Wordpress. Any help would be greatly appreciated...
<script src="http://code.jquery.com/jquery-1.8.3.js" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function() {
var divswitch = $('div.diagram_container a');
divswitch.bind('click',function(event){
var $anchor = $(this);
var ids = divswitch.each(function(){
$($(this).attr('href')).hide();
});
$($anchor.attr('href')).show();
event.preventDefault();
});
});
</script>

.diagram {
margin: 0;

Wordpress uses by default jQuery.noConflict(). This is to assure that there is no conflict by other libraries using the $ variable. That's why your console says it's not a function.
However, obviously, the jQuery variable still works, and you should use that, and passing to your function the $ variable yourself to enable the shorthand version of jQuery.
So your code should look like this:
jQuery(document).ready(function($){
// Your functions go here
});
My guess is that your Wordpress install or a plugin is already loading up jQuery in the head. Check to see if it exists there, and if it does, don't call it again.
If that doesn't do it and you have this site online, send me the link and I'll take a look.
Calling jQuery twice will often lead to problems. There is also a proper way to load jQuery and override the Wordpress version if you specifically need 1.8.3 (wp_register_script and wp_enqueue_script), but I don't think you need to go down that route yet.
Ok I have a small question.
I have the following
<div><span class="spanright" onclick"">Update</span><label class="myinfo"><b>Business information:</b></label></div>
What I want to do is when the user clicks on the span it changes the html after the label an adds an input box and submit button.
I think I need to do a this.document but not sure
Hi hope this might give you a small understanding of what to do when it comes to registering events. StackOverflow is about you learning how to do something, so we dont write the scripts for you, we are just trying to point you in the right direction of it.

I would recommend you to import jQuery library, as done in the example, if possible. It makes the the world of javascript alot easier!
Documentation to look up:
http://api.jquery.com/insertAfter/
http://api.jquery.com/bind/
Look up some jQuery tutorials! there is alot of them out there.
I added a form which will hold the input
JavaScript:
function showInput()
{
document.getElementById('container').innerHTML += '<input type="text"/><input type="submit"/>';
}
HTML:
<div id="container">
<span class="spanright" onclick"showInput()">Update</span>
<label class="myinfo"><b>Business information:</b></label>
</div>
Summoner's answer is right, but I prefer using jquery (it's loaded on almost every page I work with):
HTML:
<div id="container">
<span class="spanright">Update</span>
<label class="container"><b>Business information:</b></label>
</div>
Javascript:
$(".spanright").click(function(){
$("#container").append('<br /><input type="text"/><input type="submit"/>');
$(".spanright").unbind('click');
});
This way, the click event will work once, as it is what you probably intended.
Try this in jquery flavor --
$(document).ready(function(){
$(".spanright").click(function(){
$(".myinfo").css("color","red");
});
});

Just wondering if there is a way to get a HTML <button> element to link to a location without wrapping it in an <a href... tag?
Button currently looks like:
<button>Visit Page Now</button>
What I would prefer not to have:
<button>Visit Page Now</button>
The button is not being used within a form so <input type="button"> is not an option. I am just curious to see if there is a way to link this particular element without needing to wrap it in an <a href tag.
Looking forward to hearing some options/opinions.
Inline Javascript:
<button onclick="window.location='http://www.example.com';">Visit Page Now</button>
Defining a function in Javascript:
<script>
function visitPage(){
window.location='http://www.example.com';
}
</script>
<button onclick="visitPage();">Visit Page Now</button>
or in Jquery
<button id="some_id">Visit Page Now</button>
$('#some_id').click(function() {
window.location='http://www.example.com';
});
Here's a solution which will work even when JavaScript is disabled:
<form action="login.html">
<button type="submit">Login</button>
</form>
The trick is to surround the button with its own <form> tag.
I personally prefer the <button> tag, but you can do it with <input> as well:
<form action="login.html">
<input type="submit" value="Login"/>
</form>
Just do this
<button OnClick=" location.href='link.html' ">Visit Page Now</button>
Although, it's been a while since I've touched JavaScript - maybe location.href is outdated? Anyways, that's how I would do it.
LINKS ARE TRICKY
Consider the tricks that <a href> knows by default but javascript linking won't do for you. On a decent website, anything that wants to behave as a link should implement these features one way or another. Namely:
Ctrl+Click: opens link in new tabYou can simulate this by using a window.open() with no position/size argument
Shift+Click: opens link in new windowYou can simulate this by window.open() with size and/or position specified
Alt+Click: download targetPeople rarely use this one, but if you insist to simulate it, you'll need to write a special script on server side that responds with the proper download headers.
EASY WAY OUT
Now if you don't want to simulate all that behaviour, I suggest to use <a href> and style it like a button, since the button itself is roughly a shape and a hover effect. I think if it's not semantically important to only have "the button and nothing else", <a href> is the way of the samurai. And if you worry about semantics and readability, you can also replace the button element when your document is ready(). It's clear and safe.
Well, for a link, there must be a link tag around. what you can also do is that make a css class for the button and assign that class to the link tag. like,
#btn {
background: url(https://image.flaticon.com/icons/png/128/149/149668.png) no-repeat 0 0;
display: block;
width: 128px;
height: 128px;
border: none;
outline: none;
}
You can make it a non-submitting button (<button type="button">) and hook something like window.location = 'http://where.you.want/to/go' into its onclick handler. This does not work without javascript enabled though.
Or you can make it a submit button, and do a redirect on the server, although this obviously requires some kind of server-side logic, but the upside is that is doesn't require javascript.
(actually, forget the second solution - if you can't use a form, the submit button is out)
<form action="portfolio.html">
<button type="link" class="btn btn-primary btn-lg">View Work</button>
</form>
I just figured this out, and it links perfectly to another page without having my default link settings over ride my button classes! :)
Here it is using jQuery. See it in action at http://jsfiddle.net/sQnSZ/
<button id="x">test</button>
$('#x').click(function(){
location.href='http://cnn.com'
})
Assuming that in your HTML file you've a button with id="Button", In the script.js(your script file), you can use this way:
document.getElementById("Button").addEventListener("click", gotoUrl);
function gotoUrl() {
window.location.assign("https://www.google.com/");
}
Now the button will lead you to Google!

You can also try this<button type=“Submit”><a href=“”>#</a></button>
