I'm trying to create a site, on which you can download a file by pressing an button. The thing is, that I want people to click another button first to subscribe to a youtube channel and THEN to be able to download the file. So, I have to get rid of the disabled class on the download button after pressing the subscribe button. Here below is my code, what am I doing wrong?
EDIT: Tried all the answers now, none did work. I'm getting this error, what does that mean?
Uncaught ReferenceError: $ is not defined

<a id="dl" href="#" class="btn size-3 disabled">Download Exyther</a>
jsFiddle: https://jsfiddle.net/qrc3qm2e/
I have added extra code to check if the button shouldn't be clickable, if you need a jQuery answer please follow this link https://jsfiddle.net/qrc3qm2e/1/
Javascript
var subElement = document.getElementById("sub");
var dlElement = document.getElementById("dl");
subElement.onclick = function(event)
{
dlElement.classList.remove('disabled');
dlElement.removeAttribute('disabled');
};
dlElement.onclick = function(event)
{
if(dlElement.className.indexOf('disabled') > -1)
{
event.preventDefault();
return;
}
};
HTML
<a id="sub" href="#" target="blank" class="btn size-3">Subscribe to ZERO</a>
<a id="dl" href="#" target="blank" class="btn size-3 disabled" disabled="disabled">Download Exyther</a>
This makes your code an error: function()) << double close
correct JS
$('#sub').on('click',function(event){
event.preventDefault();
$('#dl').removeClass('disabled');
});
https://codepen.io/jacobweyer/pen/JNzgJE?editors=1111
Here's a codepen of the issue
$('#sub').on('click', function(event){
if (event.preventDefault) {
event.preventDefault();
}
$('#dl').removeClass('disabled');
});
You didn't close the function, but also you can add event into the function. This will pass the click event into your jquery.
With the click event you can actually prevent the page from jumping moving as well by preventing the default action on the a tag.
You can help by keeping your example really really simple. We don't need to know about your font for example. : )
You probably want to use a disabled property - or that AND style that a bit with CSS. here's how to do that. - if you want to use a link - then the download will be its default behaviour - so you shouldn't have to prevent it - but see #JacobW 's about that. You'd likely not want the URL in the markup - if you are really trying to dissuade them from getting the file until subscribing. If you can't switch out the button for the link - and see the concept, I'm sure you will at some later date. : ) Good Luck!
JavaScript - and disabled property
https://jsfiddle.net/sheriffderek/3t0pn6gv/
markup
<button class='one'>one</button>
<button class='two' disabled>two</button>
style
button:disabled {
opacity: .3;
}
script (not jQuery for #Canvas)
var signupButton = document.querySelector('button.one');
var downloadButton = document.querySelector('button.two');
signupButton.addEventListener('click', function() {
downloadButton.disabled = false;
});
with jQuery and CSS class - (not actually disabled... but looks so)
https://jsfiddle.net/sheriffderek/wyx1od9g/
markup
<button class='one'>one</button>
<button class='two disabled'>two</button>
style
.disabled{
opacity: .2;
}
script
$('button.one').on('click', function() {
$('button.two').removeClass('disabled');
});
Good day,
I have a function inside a javaScript file. I have 10 button will trigger this function to do something based on the button name. The code is something as follow:
function doSomething( name ){
switch(name){
case "1";
alert("i am 1");
break;
case "2";
alert("i am 1");
break;
// and so on...
}
}
This doSomething is working fine. However, I would like to alert other things when there is noscript or JavaScript is disable.
I do something like:
<noscript>
// if click on button 1, display <image src="image/img1" />
// if click on button 2, display <image src="image/img2" />
// and so on..
// I would like display different image when different button clicked.
</noscript>
Kindly advise.
No way. HTML5 itself is just a document sturcture and CSS3 provides style. That is, HTML5 as is has no behavior, thus, you won't be able to interact with the document without JavaScript.
If JavaScript is disabled and you provide a <noscript> element, you should tell your users that your Web application won't work without JavaScript.
You could do something like the checkbox hack in css to show a message in a hidden div, Style the labels like your buttons.
input[type=checkbox] {
position: absolute;
top: -9999px;
left: -9999px;
}
label {
background: #08C;
padding: 5px;
border: 1px solid rgba(0,0,0,.1);
border-radius: 2px;
color: white;
font-weight: bold;
}
.to-be-changed {display:none;}
input[type=checkbox]:checked ~ .to-be-changed {
display:block;
margin-top:30px;
font-size:120%;
color:red;
}
<noscript>
<div id="buttons">
<input type="checkbox" id="button1"><label for="button1">button 1</label>
<input type="checkbox" id="button2"><label for="button2">button 2</label>
<input type="checkbox" id="button3"><label for="button3">button 3</label>
<div class="to-be-changed"> You need to have javascript activated for the buttons to work !</div>
</div>
</noscript>
Obviously turn js off to se it working. Here's a link to the page I got the info from Css click events
I can't seem to figure out any way to remove the "No file selected" text that shows up next to inputs of type "file".
Do you guys know any way how to remove this text?
input[type='file'] {
color: transparent;
}
Enjoy
There is no cross-browser way to do this. The "no file selected" text is in the implementation-defined part of the widget, and I don't believe that most browsers offer much in the way of browser-specific customization. On the other hand, you could simply use CSS to cover the text with something when the value attribute is empty.
You can do this by defining a width to the input and hiding the exceeding content (the undesired "No file selected" text).
input {
width: 132px;
overflow:hidden;
}
Here is the demonstration on jsfiddle.
Beware: each language has its own default text and it may render different input sizes. In brazilian portuguese that 132px width is fine!
My answer was based on this similar question on stackoverflow.
You can replace the file field with a button with the answer to this question: file upload button without input field?
CSS
<style>
#image_file{
position: relative;
width: 188px;
border: 1px solid #BBB;
margin: 1px;
cursor: pointer;
float: left;
}
</style>
HTML
<input id="image_file" onclick="getFile()" onfocus="this.blur()" value=""/>
<div style='height: 0px;width: 0px; overflow:hidden;'>
<input type="file" id="PinSpot_file">
</div>
<input type="button" onclick="getFile()" style="background-color: #DDD;" value="Browser" >
JAVASCRIPT
function getFile(){
document.getElementById("PinSpot_file").click();
}
// Event when change fields
$('#PinSpot_file').live('change', function(e) {
var file = this.value;
var fileName = file.split("\\");
document.getElementById("image_file").value = fileName[fileName.length-1];
//AJAX
}
This is a really good hack and its a lot cleaner.
HTML
<div id="file_info' style='display:inline;'>Browse</div>
<input type="file" name='file[]' multiple style='opacity: 0;' onchange='displayFileName()'/>
JS
function displayFileName() {
var files = $('input[type="file"]')[0].files;
document.getElementById('file_info').innerHTML = files.length + " images to upload";`
}
Well, since there is no way to completely disable the text, I'd suggest either placing an element over the text or try the following solution..
CSS
input[type="file"] {
width: 90px; /* Keep it under 100px in order to hide the unwanted text. */
}
and add an html inline-title attribute to the element to hide the "No File Chosen" hover text.
HTML
<input type="file" id="FileId" title="">
or, you could do it all with JavaScript.
JS
document.addEventListener('DOMContentLoad', myFunction);
function myFunction() {
const FilePicker = document.getElementById('FileId');
FilePicker.style.width = "90px";
FilePicker.title = ""; // Leave This Empty
}
You can try this. Its work for me firefox browser
<style type="">
input[type='file'] {
color: transparent;
}
</style>
Is there a way to style (or script) <input type=file /> element to have visible only "Browse" button without text field?
Thanks
Edit:
Just to clarify why to I need this. I'm using multi file upload code from http://www.morningz.com/?p=5 and it doesn't need input text field because it never has value. Script just adds newly selected file to collection on page. It would look much better without text field, if it's possible.
<input type="file" id="selectedFile" style="display: none;" />
<input type="button" value="Browse..." onclick="document.getElementById('selectedFile').click();" />
This will surely work as I have used it in my projects.
I was having a heck of a time trying to accomplish this. I didn't want to use a Flash solution, and none of the jQuery libraries I looked at were reliable across all browsers.
I came up with my own solution, which is implemented completely in CSS (except for the onclick style change to make the button appear 'clicked').
You can try a working example here: http://jsfiddle.net/VQJ9V/307/ (Tested in FF 7, IE 9, Safari 5, Opera 11 and Chrome 14)
It works by creating a big file input (with font-size:50px), then wrapping it in a div that has a fixed size and overflow:hidden. The input is then only visible through this "window" div. The div can be given a background image or color, text can be added, and the input can be made transparent to reveal the div background:
HTML:
<div class="inputWrapper">
<input class="fileInput" type="file" name="file1"/>
</div>
CSS:
.inputWrapper {
height: 32px;
width: 64px;
overflow: hidden;
position: relative;
cursor: pointer;
/*Using a background color, but you can use a background image to represent a button*/
background-color: #DDF;
}
.fileInput {
cursor: pointer;
height: 100%;
position:absolute;
top: 0;
right: 0;
z-index: 99;
/*This makes the button huge. If you want a bigger button, increase the font size*/
font-size:50px;
/*Opacity settings for all browsers*/
opacity: 0;
-moz-opacity: 0;
filter:progid:DXImageTransform.Microsoft.Alpha(opacity=0)
}
Let me know if there are any problems with it and I'll try to fix them.
I wasted my day today getting this to work. I found none of the solutions here working each of my scenarios.
Then I remembered I saw an example for the JQuery File Upload without text box. So what I did is that I took their example and stripped it down to the relevant part.
This solution at least works for IE and FF and can be fully styled. In the below example the file input is hidden under the fancy "Add Files" button.
<html>
<head>
<title>jQuery File Upload Example</title>
<style type="text/css">
.myfileupload-buttonbar input
{
position: absolute;
top: 0;
right: 0;
margin: 0;
border: solid transparent;
border-width: 0 0 100px 200px;
opacity: 0.0;
filter: alpha(opacity=0);
-o-transform: translate(250px, -50px) scale(1);
-moz-transform: translate(-300px, 0) scale(4);
direction: ltr;
cursor: pointer;
}
.myui-button
{
position: relative;
cursor: pointer;
text-align: center;
overflow: visible;
background-color: red;
overflow: hidden;
}
</style>
</head>
<body>
<div id="fileupload" >
<div class="myfileupload-buttonbar ">
<label class="myui-button">
<span >Add Files</span>
<input id="file" type="file" name="files[]" />
</label>
</div>
</div>
</body>
</html>
Add a label tag with for attribute assign the for attribute value to the file input button.
Now when you click the label, the browser will open up the file browse dialogue popup automatically.
Note: Hide the file input button using CSS.
Check the live demo below.
$('#imageUpload').change(function() {
readImgUrlAndPreview(this);
function readImgUrlAndPreview(input) {
if (input.files && input.files[0]) {
var reader = new FileReader();
reader.onload = function(e) {
$('#imagePreview').removeClass('hide').attr('src', e.target.result);
}
};
reader.readAsDataURL(input.files[0]);
}
});
.hide {
display: none;
}
.btn {
display: inline-block;
padding: 4px 12px;
margin-bottom: 0;
font-size: 14px;
line-height: 20px;
color: #333333;
text-align: center;
vertical-align: middle;
cursor: pointer;
border: 1px solid #ddd;
box-shadow: 2px 2px 10px #eee;
border-radius: 4px;
}
.btn-large {
padding: 11px 19px;
font-size: 17.5px;
-webkit-border-radius: 4px;
-moz-border-radius: 4px;
border-radius: 4px;
}
#imagePreview {
margin: 15px 0 0 0;
border: 2px solid #ddd;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<div clas="file_input_wrap">
<input type="file" name="imageUpload" id="imageUpload" class="hide" />
<label for="imageUpload" class="btn btn-large">Select file</label>
</div>
<div class="img_preview_wrap">
<img src="" id="imagePreview" alt="Preview Image" width="200px" class="hide" />
</div>
Hide the input-file element and create a visible button that will trigger the click event of that input-file.
Try this:
CSS
#file { width:0; height:0; }
HTML:
<input type='file' id='file' name='file' />
<button id='btn-upload'>Upload</button>
JAVASCRIPT(jQuery):
$(function(){
$('#btn-upload').click(function(e){
e.preventDefault();
$('#file').click();}
);
});
I tried to implement the top two solutions, and it ended up being a HUGE waste of time for me. In the end, applying this .css class solved the problem...
input[type='file'] {
color: transparent;
}
Done! super clean and super simple...
That's going to be very hard. The problem with the file input type is that it usually consists of two visual elements, while being treated as a single DOM-element. Add to that that several browsers have their own distinct look and feel for the file input, and you're set for nightmare. See this article on quirksmode.org about the quirks the file input has. I guarantee you it won't make you happy (I speak from experience).
[EDIT]
Actually, I think you might get away with putting your input in a container element (like a div), and adding a negative margin to the element. Effectively hiding the textbox part off screen.
Another option would be to use the technique in the article I linked, to try to style it like a button.
Fix to work in all browsers
RESOLVED:
<input type = "button" value = "Choose image"
onclick ="javascript:document.getElementById('imagefile').click();">
<input id = "imagefile" type="file" style='visibility: hidden;' name="img"/>
I have tested in FF, Chrome & IE - working fine, applied styles too :D
Here is my good ol' remedy:
<input type="file" id="myFile" style="display:none;" />
<button type="button" onclick="document.getElementById('myFile').click();">Browse</button>
At least it worked in Safari.
Plain and simple.
Another easy way of doing this. Make a "input type file" tag in html and hide it. Then click a button and format it according to need. After this use javascript/jquery to programmatically click the input tag when the button is clicked.
HTML :-
<input id="file" type="file" style="display: none;">
<button id="button">Add file</button>
JavaScript :-
document.getElementById('button').addEventListener("click", function() {
document.getElementById('file').click();
});
jQuery :-
$('#button').click(function(){
$('#file').click();
});
CSS :-
#button
{
background-color: blue;
color: white;
}
Here is a working JS fiddle for the same :- http://jsfiddle.net/32na3/
I used some of the code recommended above and after many hours of waisting my time, I eventually came to a css bag free solution.
You can run it over here - http://jsfiddle.net/WqGph/
but then found a better solution - http://jsfiddle.net/XMMc4/5/
<input type = "button" value = "Choose image #2"
onclick ="javascript:document.getElementById('imagefile').click();">
<input id = "imagefile" type="file" style='display:none;' name="img" value="none"/>see jsfiddle code for examples<br/>
You could label an image so when you click on it the click event of the button will be triggered. You can simply make the normal button invisible:
<form>
<label for="fileButton"><img src="YourSource"></label> <!--You don't have to put an image here, it can be anything you like-->
<input type="file" id="fileButton" style="display:none;"/>
</form>
It worked for me on all browsers, and is very easy to use.
You can dispatch the click event on a hidden file input like this:
<form action="#type your action here" method="POST" enctype="multipart/form-data">
<div id="yourBtn" style="height: 50px; width: 100px;border: 1px dashed #BBB; cursor:pointer;" >Click to upload!</div>
<!-- hide input[type=file]!-->
<div style='height: 0px;width:0px; overflow:hidden;'><input id="upfile" type="file" value="upload"/></div>
<input type="submit" value='submit' >
</form>
<script type="text/javascript">
var btn = document.getElementById("yourBtn");
var upfile = document.getElementById("upfile");
btn.addEventListener('click',function(){
if(document.createEvent){
var ev = document.createEvent('MouseEvents');
ev.initEvent('click',true,false);
upfile.dispatchEvent(ev);
}else{
upfile.click();
}
});
</script>
HTML:
<input type="file" name="upload" id="upload" style="display:none"></input>
<button id="browse">Upload</button>
JQUERY
$(document).ready(function(){
$("#browse").click(function(){
$("#upload").click();
});
});
Hope this works :)
This HTML code show up only Upload File button
<form action="/action_page.php">
<input type="button" id="id" value="Upload File" onclick="document.getElementById('file').click();" />
<input type="file" style="display:none;" id="file" name="file" onchange="this.form.submit()"/>
</form>
You can give the input element a font opacity of 0. This will hide the text field without hiding the 'Choose Files' button.
No javascript required, clear cross browser as far back as IE 9
E.g.,
input {color: rgba(0, 0, 0, 0);}
Ive a really hacky solution with this...
<style type="text/css">
input[type="file"]
{
width: 80px;
}
</style>
<input id="File1" type="file" />
The problem is the width attribute that is hiding the text field will obvously vary between browsers, vary between Windows XP themes and so on. Maybe its something you can work with though?...
I know this is an old post but a simple way to make the text dissapear is just to set text color to that of your background.
eg if your text input background is white then:
input[type="file"]{
color:#fff;
}
This will not effect the Choose File text which will still be black due to the browser.
There is a simple and hacky way to show only the file input button while keeping the render and translations of this file input button :
Make the text that is displayed after a file input invisible using a the color transparent.
<input type="file" style="color: transparent" />
my solution is just to set it within a div like "druveen" said, however i ad my own button style to the div (make it look like a button with a:hover) and i just set the style "opacity:0;" to the input. Works a charm for me, hope it does the same for you.
This works for me:
input[type="file"] {
color: white!important;
}
I just styled an input file with width: 85px, and the text field disappeared at all
Select Logo <input type="file" id="logo">
$("#logo").css('opacity','0');
$("#select_logo").click(function(){
$().trigger('click');
return false;
});
For me, the simplest way is using a font color like background color. Simple, not elegant, but usefull.
<div style="color:#FFFFFF"> <!-- if background page is white, of course -->
<input class="fileInput" type="file" name="file1"/></div>
So here's the best way to do this FOR ALL BROWSERS:
Forget CSS!
<p>Append Image:</p>
<input type="button" id="clickImage" value="Add Image" />
<input type="file" name="images[]" id="images" multiple />
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js" charset="utf-8"></script>
<script>
$('#images').hide();
$('#clickImage').click( function() {
$('#images').trigger('click');
});
</script>
All these answers are cute, but CSS won't work since it isn't the same across all browsers and devices, the first answer I wrote will work in everything but Safari. To get it to work accross all browsers all the time it must be created dynamically and recreated every time you want to clear the input text:
var imageDiv = document.createElement("div");
imageDiv.setAttribute("id", "imagediv");
imageDiv.style.cssText = 'position:relative; vertical-align: bottom;';
var imageText = document.createTextNode("Append Image:");
var newLine = document.createElement("br");
var image = document.createElement("input");
image.setAttribute("type", "file");
image.setAttribute("id", "images");
image.setAttribute("name", "images[]");
image.setAttribute("multiple", "multiple");
imageDiv.appendChild(imageText);
imageDiv.appendChild(newLine);
imageDiv.appendChild(image);
questionParagraph.appendChild(imageDiv);
The answer of tmanthey is quite good, except that you can't play with border-width in Firefox v20. If you see the link (demo, can't really show here) they solved the problem using font-size=23px, transform:translate(-300px, 0px) scale(4) for Firefox to get the button bigger.
Other solutions using .click() on a different div is useless if you want to make it a drag'n'drop input box.
There are several valid options here but thought I would give what I have come up with while trying to fix a similar issue. http://jsfiddle.net/5RyrG/1/
<span class="btn fileinput-button">
<span>Import Field(s)</span>
<input id="fileupload" type="file" name="files[]" onchange="handleFiles(this.files)" multiple>
</span>
<div id="txt"></div>
function handleFiles(files){
$('#txt').text(files[0].name);
}
I wrote this:
<form action='' method='POST' name='form-upload-image' id='form-upload-image' enctype='multipart/form-data'>
<div style="width: 0; height: 0; overflow: hidden;">
<input type="file" name="input-file" id="input-file" onchange="this.files.length > 0 ? document.getElementById('form-upload-image').submit():null;" />
</div>
</form>
<img src="image.jpg" style="cursor: pointer;" onclick="document.getElementById('input-file').click();" />
Work fine in all browsers, no jQuery, no CSS.
Here is a simplified version of #ampersandre's popular solution that works in all major browsers.
Asp.NET markup
<asp:TextBox runat="server" ID="FilePath" CssClass="form-control"
style="float:left; display:inline; margin-right:5px; width:300px"
ReadOnly="True" ClientIDMode="Static" />
<div class="inputWrapper">
<div id="UploadFile" style="height:38px; font-size:16px;
text-align:center">Upload File</div>
<div>
<input name="FileUpload" id="FileInput" runat="server"
type="File" />
</div>
</div>
<asp:Button ID="UploadButton" runat="server"
style="display:none" OnClick="UploadButton_Click" />
</div>
<asp:HiddenField ID="hdnFileName" runat="server" ClientIDMode="Static" />
JQuery Code
$(document).ready(function () {
$('#UploadFile').click(function () {
alert('UploadFile clicked');
$('[id$="FileInput"]').trigger('click');
});
$('[id$="FileInput"]').change(function (event) {
var target = event.target;
var tmpFile = target.files[0].name;
alert('FileInput changed:' + tmpFile);
if (tmpFile.length > 0) {
$('#hdnFileName').val(tmpFile);
}
$('[id$="UploadButton"]').trigger('click');
});
});
css code
.inputWrapper {
height: 38px;
width: 102px;
overflow: hidden;
position: relative;
padding: 6px 6px;
cursor: pointer;
white-space:nowrap;
/*Using a background color, but you can use a background image to represent
a button*/
background-color: #DEDEDE;
border: 1px solid gray;
border-radius: 4px;
-moz-user-select: none;
-ms-user-select: none;
-webkit-user-select: none;
user-select: none;
}
Uses a hidden "UploadButton" click trigger for server postback with standard . The with "Upload File" text pushes the input control out of view in the wrapper div when it overflows so there is no need to apply any styles for the "file input" control div. The $([id$="FileInput"]) selector allows section of ids with standard ASP.NET prefixes applied. The FilePath textbox value in set from server code behind from hdnFileName.Value once file is uploaded.
