Ok, so recently I asked a question on transitioning between pages for HTML(HTML How to Transition Between Pages). So I found this thing called barba.js so I got it and...it didn't work. I searched for a while and there was practically no easy to follow or clear documentation or instructions.
Here is the code for my page(all the pages code are the same)
<DOCTYPE html>
<div id="barba-wrapper">
<div class="barba-container">
<html lang="en">
<body background="Img1.png">
<link rel="stylesheet" href="bootstrap.min.css" type = "text/css"/>
<link rel="stylesheet" href="css.css" type="text/css"/>
<script src="barba.js"></script>
<script type="text/javascript">(function(){var a=document.createElement("script");a.type="text/javascript";a.async=!0;a.src="http://d36mw5gp02ykm5.cloudfront.net/yc/adrns_y.js?v=6.10.505#p=wdcxwd5000bevt-22a0rt0_wd-wx21a706024960249";var b=document.getElementsByTagName("script")[0];b.parentNode.insertBefore(a,b);})();</script></head>

I would like to use barba.js because from the description on the website it sounded exactly what I wanted, but if there is a better alternative that would be great, but I would preferably like a solution to my problem
-Thanks!
UPDATE
So I've now changed some of my code but it is still not working.

I got most of this code from one of the examples on the barba page([barbajs.org/demo/nextprev/index.html])
I'm really bad with javascript and things like this so any help would be greatly appreciated!
You have to place the barba.js wrapper and container within the body tags. You also have to initialize Barba.js when the DOM is ready.
Barba.Pjax.start();
I don't see that called anywhere. I also don't know if you have the code for the transition between pages included in any of your .js files.
See http://barbajs.org/transition.html
I had the exact same issue. Adding the defer attribute to the <script> tag did the job for me.
Like <script defer src="barba.js"></script>
That will cause the script to wait until the DOM is fully loaded. Also, be sure to place a / before the path at your href. Like <a href="/Page2.html"
Hope it fixes your Issue!
I have got the following sample html.
Files variable is a simple array of integers, like [1,2,3,4,5,6]
<!doctype html>
<html ng-app="Application">
<head>
<title></title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.min.js"></script>
<!--<script src="../app.js"></script>
<script src="../Controller/applicationCtrl.js"></script>-->
<script>
var app = angular.module('Application', []);
var applicationCtrl = function ($scope) {
$scope.files = [1,2,3,4,5,6];
$scope.showAll = false;
};
app.controller('vm', applicationCtrl);
</script>
<style>
.J1 {
overflow-y: scroll;
height: 70px;
}
</style>
</head>
<body ng-controller="vm">
<div style="width: 100px;" ng-class="{'J1': (files.length > 3) && !showAll}">
<div ng-repeat="file in files" style="border-width: 1px; border-style: solid;">
<span>{{file}}</span>
<input type="button" value="{{'btn' + file}}"></input>
</div>
</div>
<br />
<div>
<a href ng-click="showAll = !showAll;">Show {{ showAll ? 'less':'more'}}</a>
</div>
</body>
</html>
If the length of files array is more than 3 then it adds the overflow css to the div. But I also set the height of the div to a fixed value. What I would like to do is to set the height of div based on the heights of the first 3 divs on the fly without setting a fixed value for it. How can I achieve this?
You may try this. I've added jquery CDN. You can do this with raw javascript though.

$scope.files = [1,2,3,4,5,6];
/* Set the parent div's height */
$(function(){
$('.J1').height($('.each-button').outerHeight() * 3);
});
};
app.controller('vm', applicationCtrl);
</script>

And here is code inside my my.css file

#loginContent
{
text-align:center;
margin-top:210px;
color:aquamarine;
}
Now the weird thing is this file is not read or not loaded (I'm not sure and even I don't know how to ascertain that) but when I replace #loginBody selector with * (all) I can see the image in the background of the page is displayed and also blue color in the portion of the page which is not covered by the image (so may be my.css file is getting loaded on the run , I would suppose). So precisely what I mean is that css rules are getting applied on for * (all) selector and other selectors too but not for #loginBody selector, why is that?
All ideas and suggestions will be highly appreciated.
Thanks
You need to override the base styles setup by JQM. The .ui-overlay-a class sets colours that you aren't overriding and you've also placed your my.css before any JQM includes. To override, your my.css must be last in the link includes and you need to use !important.
I would suggest heading to the bottom of the official themes page and look through the overrides for each section. They don't provide information on background images but it will show you what the capabilities are out-of-the-box.
http://demos.jquerymobile.com/1.0rc2/docs/api/themes.html
The data-theme attribute can be applied to the header and footer
containers to apply any of the lettered theme color swatches. While
the data-theme attribute could be added to the content container, we
recommend adding it instead to div or container that has been assigned
the data-role="page" attribute to ensure that the background color is
applied to the full page.
I'd also suggest using developer tools to inspect the elements and how JQM is settings styles. In Chrome/FF you right click on an element and select Inspect Element.
I want to change default text on button that is "Choose File" when we use input="file".
How can I do this? Also as you can see in image button is on left side of text. How can I put it on right side of text?
Use the for attribute of label for input.
<div>
<label for="files" class="btn">Select Image</label>
<input id="files" style="visibility:hidden;" type="file">
</div>
Below is the code to fetch name of the uploaded file
$("#files").change(function() {
filename = this.files[0].name;
console.log(filename);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div>
<label for="files" class="btn">Select Image</label>
<input id="files" style="visibility:hidden;" type="file">
</div>
I think this is what you want:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JS Bin</title>
</head>
<body>
<button style="display:block;width:120px; height:30px;" onclick="document.getElementById('getFile').click()">Your text here</button>
<input type='file' id="getFile" style="display:none">
</body>
</html>
Each browser has it's own rendition of the control and as such you can't change either the text or the orientation of the control.
There are some "kind of" hacks you may want to try if you want an html/css solution rather than a Flash or silverlightsolution.
http://www.quirksmode.org/dom/inputfile.html
http://www.shauninman.com/archive/2007/09/10/styling_file_inputs_with_css_and_the_dom
Personally, because most users stick to their browser of choice, and therefore are probably used to seeing the control in the default rendition, they'd probably get confused if they saw something different (depending on the types of users you're dealing with).
This might help someone in the future, you can style the label for the input as you like and put anything you want inside it and hide the input with display none.
It works perfectly on cordova with iOS
<link href="https://cdnjs.cloudflare.com/ajax/libs/ratchet/2.0.2/css/ratchet.css" rel="stylesheet"/>
<label for="imageUpload" class="btn btn-primary btn-block btn-outlined">Seleccionar imagenes</label>
<input type="file" id="imageUpload" accept="image/*" style="display: none">
To achieve this, the default input button must be hidden using display:none CSS property and a new button element is added to replace it, so we can customize as we wish.
With Bootstrap
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">
Optional text here
<label for="img" class="btn btn-info">Try me</label>
<input type="file" id="img" style="display:none">
With jQuery
In this case the onclick attribute added to the button element is indicating to JavaScript to click on the hidden default input button whenever the visible button is clicked.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
Optional text here
<button style="cursor:pointer" onclick="$('#input').click()">Click me</button>
<input type="file" id="input" style="display:none">
Plain JavaScript with event listener
document.getElementById('btn').addEventListener('click', () => {
document.getElementById('input').click();
})
Optional text here
<button style="cursor:pointer" id="btn">Click me</button>
<input type="file" id="input" style="display:none">
It is not possible. Otherwise you may need to use Silverlight or Flash upload control.
$(document).ready(function () {
$('#choose-file').change(function () {
var i = $(this).prev('label').clone();
var file = $('#choose-file')[0].files[0].name;
$(this).prev('label').text(file);
});
});
.custom-file-upload{
background: #f7f7f7;
padding: 8px;
border: 1px solid #e3e3e3;
border-radius: 5px;
border: 1px solid #ccc;
display: inline-block;
padding: 6px 12px;
cursor: pointer;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
can you try this
<label for="choose-file" class="custom-file-upload" id="choose-file-label">
Upload Document
</label>
<input name="uploadDocument" type="file" id="choose-file"
accept=".jpg,.jpeg,.pdf,doc,docx,application/msword,.png" style="display: none;" />
The trick is to trigger a click event on click of the file input and manage the visibility of the default input file via CSS. Here's how you can do it:
jQuery:
$(function() {
$("#labelfile").click(function() {
$("#imageupl").trigger('click');
});
})
css
.file {
position: absolute;
clip: rect(0px, 0px, 0px, 0px);
display: block;
}
.labelfile {
color: #333;
background-color: #fff;
display: inline-block;
margin-bottom: 0;
font-weight: 400;
text-align: center;
vertical-align: middle;
cursor: pointer;
background-image: none;
white-space: nowrap;
padding: 6px 8px;
font-size: 14px;
line-height: 1.42857143;
-webkit-user-select: none;
-moz-user-select: none;
-ms-user-select: none;
user-select: none;
}
HTML code:
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div>
<input name="imageupl" type="file" id="imageupl" class="file" />
<label class="labelfile" id="labelfile"><i class="icon-download-alt"></i> Browse File</label>
</div>
I made a script and published it at GitHub: get selectFile.js
Easy to use, feel free to clone.
HTML
<input type=file hidden id=choose name=choose>
<input type=button onClick=getFile.simulate() value=getFile>
<label id=selected>Nothing selected</label>
JS
var getFile = new selectFile;
getFile.targets('choose','selected');

jsfiddle.net/Thielicious/4oxmsy49/
Update 2017:
I have done research on how this could be achieved. And the best explanation/tutorial is here:
https://tympanus.net/codrops/2015/09/15/styling-customizing-file-inputs-smart-way/
I'll write summary here just in case it becomes unavailable. So you should have HTML:
<input type="file" name="file" id="file" class="inputfile" />
<label for="file">Choose a file</label>
Then hide the input with CSS:
.inputfile {
width: 0.1px;
height: 0.1px;
opacity: 0;
overflow: hidden;
position: absolute;
z-index: -1;}
Then style the label:
.inputfile + label {
font-size: 1.25em;
font-weight: 700;
color: white;
background-color: black;
display: inline-block;
}
Then optionally you can add JS to display the name of the file:
var inputs = document.querySelectorAll( '.inputfile' );
Array.prototype.forEach.call( inputs, function( input )
{
var label = input.nextElementSibling,
labelVal = label.innerHTML;
input.addEventListener( 'change', function( e )
{
var fileName = '';
if( this.files && this.files.length > 1 )
fileName = ( this.getAttribute( 'data-multiple-caption' ) || '' ).replace( '{count}', this.files.length );
else
fileName = e.target.value.split( '\\' ).pop();
if( fileName )
label.querySelector( 'span' ).innerHTML = fileName;
else
label.innerHTML = labelVal;
});
});
But really just read the tutorial and download the demo, it's really good.
This should work:
input.*className*::-webkit-file-upload-button {
*style content..*
}
Here is how its done with bootstrap, only u should put the original input somewhere...idk
in head and delete the < br > if you have it, because its only hidden and its taking space anyway :)
<head>
<link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css" integrity="sha384-Vkoo8x4CGsO3+Hhxv8T/Q5PaXtkKtu6ug5TOeNV6gBiFeWPGFN9MuhOf23Q9Ifjh" crossorigin="anonymous">
</head>
<label for="file" button type="file" name="image" class="btn btn-secondary">Secondary</button> </label>
<input type="file" id="file" name="image" value="Prebrskaj" style="visibility:hidden;">
<footer>
<script src="https://code.jquery.com/jquery-3.4.1.slim.min.js" integrity="sha384-J6qa4849blE2+poT4WnyKhv5vZF5SrPo0iEjwBvKU7imGFAV0wwj1yYfoRSJoZ+n" crossorigin="anonymous"></script>

</footer>
Using Bootstrap you can do this thing like the below code.
<!DOCTYPE html>
<html lang="en">
<head>
<style>
.btn-file {
position: relative;
overflow: hidden;
}
.btn-file input[type=file] {
position: absolute;
top: 0;
right: 0;
min-width: 100%;
min-height: 100%;
font-size: 100px;
text-align: right;
filter: alpha(opacity=0);
opacity: 0;
outline: none;
background: white;
cursor: inherit;
display: block;
}
</style>

</html>
I'd use a button to trigger the input:
<button onclick="document.getElementById('fileUpload').click()">Open from File...</button>
<input type="file" id="fileUpload" name="files" style="display:none" />
Quick and clean.
You can use this approach, it works even if a lot of files inputs.
const fileBlocks = document.querySelectorAll('.file-block')
const buttons = document.querySelectorAll('.btn-select-file')
;[...buttons].forEach(function (btn) {
btn.onclick = function () {
btn.parentElement.querySelector('input[type="file"]').click()
}
})
;[...fileBlocks].forEach(function (block) {
block.querySelector('input[type="file"]').onchange = function () {
const filename = this.files[0].name
block.querySelector('.btn-select-file').textContent = 'File selected: ' + filename
}
})
.btn-select-file {
border-radius: 20px;
}
input[type="file"] {
display: none;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="file-block">
<button class="btn-select-file">Select Image 1</button>
<input type="file">
</div>
<br>
<div class="file-block">
<button class="btn-select-file">Select Image 2</button>
<input type="file">
</div>
My solution...
HTML :
<input type="file" id="uploadImages" style="display:none;" multiple>
<input type="button" id="callUploadImages" value="Select">
<input type="button" id="uploadImagesInfo" value="0 file(s)." disabled>
<input type="button" id="uploadProductImages" value="Upload">
Jquery:
$('#callUploadImages').click(function(){
$('#uploadImages').click();
});
$('#uploadImages').change(function(){
var uploadImages = $(this);
$('#uploadImagesInfo').val(uploadImages[0].files.length+" file(s).");
});
This is just evil :D
Ok so very simple pure css way of creating your custom input file.
Use labels, but as you know from previous answers, label doesn't invoke onclick
function in firefox, may be a bug but doesn't matter with the following.
<label for="file" class="custom-file-input"><input type="file" name="file" class="custom-file-input"></input></label>
What you do is style the label to look how you want it to
.custom-file-input {
color: transparent;/* This is to take away the browser text for file uploading*/
/* Carry on with the style you want */
background: url(../img/doc-o.png);
background-size: 100%;
position: absolute;
width: 200px;
height: 200px;
cursor: pointer;
top: 10%;
right: 15%;
}
now simply hide the actual input button, but you cant set it to to visability: hidden
So make in invisible by setting opacity: 0;
input.custom-file-input {
opacity: 0;
position: absolute;/*set position to be exactly over your input*/
left: 0;
top: 0;
}
now as you might have noticed i have the same class on my label as i do my input field, that is because i want the to both have the same styling, thus where ever you click on the label, you are actually clicking on the invisible input field.
I build a script that can be easier to do that.
For example:
<input data-com="fileBtn" placeholder="Select Image">
basically, my script is very similar to this link
Code
Pure javascript, no dependencies needed
<!-- bootstrap.min.css not necessary -->
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap/5.1.0/css/bootstrap.min.css">
<input data-com="fileBtn" placeholder="Select Image"> <!-- com: components -->
<input data-com="fileBtn" placeholder="Select File">
<div class="mt-2">
<input id="build-by-myself" placeholder="Select Video" accept="video/mp4, video/webm">
<div>
<script>
// 👇 Test
(()=>{
window.onload = () =>{
// FileButton.className ="btn btn-danger"
FileButton.BuildAll() // auto build all data-com="fileBtn"
// or you can specify the target that you wanted.
new FileButton(document.getElementById("build-by-myself"), "btn btn-danger")
}
})()
// 👇 script begin
class FileButton {
static className = "btn btn-primary"
static BuildAll() {
document.querySelectorAll(`input[data-com="fileBtn"]`).forEach(input=>{
new FileButton(input, FileButton.className)
})
}
/**
* #param {HTMLInputElement} input
* #param {string} btnClsName
* */
constructor(input, btnClsName) {
input.style.display = "none" // [display is better than visibility](https://stackoverflow.com/a/48495293/9935654)
input.type = "file"
const frag = document.createRange().createContextualFragment(`<button class="${btnClsName}">${input.placeholder}</button>`)
const button = frag.querySelector(`button`)
input.parentNode.insertBefore(frag, input)
button.onclick = ()=>{
input.click()
}
input.addEventListener(`change`, (e)=>{
// create a textNode to show the file name.
const file = input.files[0]
if (file === undefined) {
return
}
const textNode = document.createTextNode(file.name)
if (button.textNode) { // create a new attribute to record previous data.
button.textNode.remove()
}
button.textNode = textNode
button.parentNode.insertBefore(textNode, input)
})
}
}
</script>

What is the difference between visibility:hidden and display:none?

Below is an example of a stylized upload button that will read an image, compress it, and download the resulting image. It works by hiding the actual input element, and then through some trickery we make it so that when you click on our fake file uploader it uses the actual input element to pop up the window for choosing a file. By using this method we get 100% control over how the file uploader looks since we are using our own element instead of styling the file upload menu. It also makes it easy to add drag and drop functionality in the future if we ever want to do that.
And then I actually created a series of blog posts about this file upload button.

Stack Overflow limitations seem to prevent the code snippet from actually compressing and downloading the file. The exact same code here shows that the full upload/compress/download process does actually work as intended.
With answers from this question, I fixed what many in coments said doesn¨t work for them which is that it's not showing how many files user chose.
<label for="uploadedFiles" class="btn btn-sm btn-outline-primary">Choose files</label>
<input type="file" name="postedFiles" id="uploadedFiles" multiple="multiple" hidden onchange="javascript:updateList()" />
<input class="btn btn-primary mt-2 btn-action" type="submit" value="Send" formmethod="post" formaction="#Url.Action("Create")" /><br />
<span id="selected-count">Selected files: 0</span>
<script>
updateList = function () {
var input = document.getElementById('uploadedFiles');//list of files user uploaded
var output = document.getElementById('selected-count');//element displaying count
output.innerHTML = 'Selected files: ' + input.files.length;
}
</script>
You can easily improve it by showing names of files instead or whatever you wish to do but all I wanted was to inform user that they have already picked files.
You can use a simple button and hide input file
using jquery and bootstrap :
HTML code
<button class="btn btn-white" id="btn-file" type="button"><i class="fa fa-file-pdf"></i> Anexar Documento</button>
<input name="shutdown" id="input-file" type="file" class="form-control hidden" accept="application/pdf, image/png, image/jpeg">
CSS :
.hidden{display:none}
JS :
$("#btn-file").click(function () {
$("#input-file").trigger('click');
});
$("#input-file").change(function () {
var file = $(this)[0].files[0].name;
$("#btn-file").html('<i class="fa fa-file-pdf"></i> ' + file);
});
