hiding a "No file chosen" tooltip in Javascript

I know there are many question about it, but they don't answer properly.
After readings and looking for, I tried this:
<input id="ext-element-47" class="x-input-file x-input-el" type="file" accept="" style="display:none">
hiding the file-input and then
this.element.down(".x-input-file").dom.click();
this works on Chrome's console but in my JS code it doesn't. It doesn't click.
Anyone knows why? and what can I do for make click?
Notes:
I need to make click because the file element is not visible and so when it clicks it does not show unless I do element.click ().
Here is an example what I'm doing:
document.getElementsByClassName('o-file-field-input')[0].click()
.o-file-field-input {
display: none;
}
.o-big-btn {
background-color: red;
height: 3em;
width: 3em;
}
<div class="x-container x-unsized o-cont-option" data-componentid="ext-container-5" id="ext-container-5">
<div class="x-inner x-align-center x-pack-center x-horizontal x-layout-box" id="ext-element-50">
<div class="x-button x-button-plain open-field-icon o-big-btn x-layout-box-item x-flexed x-stretched" id="ext-OUI_BaseButton-1" data-componentid="ext-OUI_BaseButton-1" tabindex="0" style="-webkit-box-flex: 1;">
<span class="x-button-icon x-shown smf smf-upload-file" id="ext-element-45"></span>
<div class="o-button-bg"></div>
<div class="x-unsized x-field-input x-has-height" id="ext-fileinput-1" data-componentid="ext-fileinput-1" style="height: 38px;">
<input id="ext-element-47" class="x-input-file x-input-el o-file-field-input" type="file" accept="">
<div class="x-field-mask x-hidden-display" id="ext-element-48"></div>
<div class="x-clear-icon" id="ext-element-49">
</div>
</div>
</div>
</div>
</div>
See ya!

Here's what I usually do: Wrap the input inside a <label> element, and then style the element as a button, for example:
.pretty-file {
border: 1px solid #000;
cursor: pointer;
display: inline-block;
padding: 5px 15px;
}
.pretty-file input[type="file"] {
display: none;
}
<label class="pretty-file">
Choose File
<input type="file" />
</label>

This finally works well:
var obElement = document.getElementsByClassName('input-file')[0];
//the title property overrides tooltip's description
obElement.setAttribute('title', ' ');
.flex-style{
display: flex;
}
.input-file{
opacity: 0;
margin-left: -40px;
width: 40px;
height: 45px;
}
.icon{
width: 40px;
height: 45px;
background-color: blueviolet;
}
<div class='flex-style'>
<div class='icon'></div>
<input class='input-file' type='file'>
</div>

How do I create a file upload anchor tag link?

Below code is working almost correctly but it always displays the "choose file" button. I need the choose file button to not display and all that's left is a link that is a file uploader.
How do I create a file upload anchor tag link properly?
This is using bootstrap-filestyle.
$(function(){
$("#upload_link").on('click', function(e){
e.preventDefault();
$("#upload:hidden").trigger('click');
});
});
#upload_link{text-decoration:none;}
#upload{display:none}
<input id="upload" type="file"/>
Upload your photo

Use This CSS
.btn-file {
display: block;
height: 20px;
overflow: hidden;
position: relative;
vertical-align: middle;
width: 120px;
}
.btn-file > input {
cursor: pointer;
direction: ltr;
font-size: 23px;
margin: 0;
opacity: 0;
position: absolute;
right: 0;
top: 0;
transform: translate(-300px, 0px) scale(4);
}
input[type="file"] {
display: block;
}
Use This HTML
<span class="btn default btn-file">
<span class="fileinput-new">
Select Document
</span>
<input type="file" class="textbox wp95 fl fileupload fileInput" name="files" id="fileupload">
</span>

Opening file select when clicking on a div not file input tag

I wanted to design an image uploader. For selecting an image we do this:
<input type="file" />
but I don't want to use that regular input, I have a div and I want that when user clicks on that, file selecting dialog opens and after that everything continues in standard way.
I want to use Angular.js rather than jQuery if possible because my project is under Angular.js

You dont need javascript to do this, please dont look at the inline style
<div style="position: relative; border: 1px solid red; width: 50px; height: 30px; line-height: 30px; text-align: center;" >
Open
<input type="file" style="opacity: 0.0; position: absolute; top: 0; left: 0; bottom: 0; right: 0; width: 100%; height:100%;" />
</div>
Note you need to add more crossbrowser opacity lines
see demo http://jsfiddle.net/yp2dykn5/
Edited this seams to be a populair question/answer.
So i updated this answer with the information below including cross browser opacity lines support.
div {
position: relative;
border: 1px solid red;
width: 50px;
height: 30px;
line-height: 30px;
text-align: center;
}
.file_upload {
opacity: 0.0;
/* IE 8 */
-ms-filter: "progid:DXImageTransform.Microsoft.Alpha(Opacity=0)";
/* IE 5-7 */
filter: alpha(opacity=0);
/* Netscape or and older firefox browsers */
-moz-opacity: 0.0;
/* older Safari browsers */
-khtml-opacity: 0.0;
position: absolute;
top: 0;
left: 0;
bottom: 0;
right: 0;
width: 100%;
height:100%;
}
<form>
<div>
Open
<input type="file" class="file_upload" />
</div>
</form>

I would give the <input> element the CSS property display: none; Then I would apply whatever styling needed to fit your situation to a <label> element linked to the <input> through the use of the for attribute (link to w3school page). In all browsers I know of, clicking on the <label> of an <input> works the same as clicking on the <input>.
This solution only using CSS and does not use JavaScript. The <label> can be styled in any way that a <div> can be styled.
Edit: I elaborated on my answer since I noticed the complexity of the top answer.
.hide {
display: none;
}
.file_upload {
border: 1px solid red;
padding: 5px;
}
<label for="getFile1" class="file_upload">Open File</label>
<input type="file" id="getFile1" class="hide"/>

My suggestion with Jquery would be to keep a div and an input[type="file"].The input should be made hidden and trigger the click of input using JQuery, like below
HTML
<div id="id">Open</div>
<input id="yourinputname" type="file" name="yourinputname" style="display: none;" />
jQuery
$('#id').on('click', function() {
$('#yourinputname').trigger('click');
});
See the fiddle

My File upload form with bootstrap and fontawesome
<html>
<head>
<link rel="stylesheet" type="text/css" href="path/to/bootstrap.css" />
<link rel="stylesheet" type="text/css" href="path/to/fontawesome-all.css" />

If you are using react: (sorry for the hideous indentation, stack would not let me format it correctly)
#getFile {
display: none;
}
<label htmlFor="getFile">
<FontIcon iconName="photo" className="uploadIcon"/>
<input type="file" id="getFile" />
</label>

Custom Upload Button

hi i was just wondering how you can create you own custom file upload button, because the best i can do is
and what i want to achieve is
if there is anyway of doing this i would be very thankful,
and please can i have answers that explain how to do it with code and not answers with links to websites that allow you to download a button or something like that,Thank You :)

Although some of these answers will create something that looks like you want it to work, they will break down when they try to perform the way that you expect. The file input doesn't style well directly and you will have trouble trying it. However, there is a trick.
The trick is to turn the opacity of the input to 0 and then change the background underneath it to the button style that you want.
.file_button_container,
.file_button_container input {
height: 47px;
width: 263px;
}
.file_button_container {
background: transparent url(http://i.stack.imgur.com/BT5AB.png) left top no-repeat;
}
.file_button_container input {
opacity: 0;
}
<div class="file_button_container"><input type="file" /></div>

I think you can also try doing it this way:
Creating an additional <label for="X"></label> element which you can style easily with CSS
<div class="container">
<label for="upload" class="uploadButton">Upload</label>
<input type="file" name="upload" id="upload">
</div>
like
.container {
position: relative;
}
.uploadButton {
height: 25px;
width: 66px;
display: block;
cursor: pointer;
background: url('http://www.ifunia.com/images/christmas/youtube-upload-button.gif') center center no-repeat;
}
input[type="file"] {
display: block;
width: 66px;
height: 25px;
clip: rect(0px 0px 0px 0px);
position: absolute;
left: 0;
top: 0;
}
<form>
<div class="container">
<label for="upload" class="uploadButton"></label>
<input type="file" name="upload" id="upload" required />
</div>
<hr/>
<button type="submit">Submit</button>
</form>

The arrow isn't something you can "just do with code" and the rounded corners would work fine in firefox, but not in ie using css... if you just need to use a custom image it's easy:
css:
#my_upload_button{
background-image:url(path-to-file.png);
border:none;
}

In Vue JS
If you wanna put the upload image button inside the textarea
use Relative and Absolute position to put the camera icon inside the textarea
use bottom-3 right-4 to find the proper position
<div class="field relative">
<label>Description</label>
<textarea class="textarea" v-model="description" type="text" maxlength="10000"> </textarea>
<label for="upload-file" class="icn icn-camera cursor-pointer absolute bottom-3 right-4">
<input type="file" id="upload-file" hidden ref="file" #change="getImage($event)" accept="image/**" />
</label>
</div>
if not inside the textarea box, just one custom upload button then just keep the code like this
<label for="upload-file" class="icn icn-camera cursor-pointer">
<input type="file" id="upload-file" hidden ref="file" #change="getImage($event)" accept="image/**" />
</label>
change the default upload file icon to a camera icon

Step 1. Create a simple html markup
<div class="fileUpload btn btn-primary">
<span>Upload</span>
<input type="file" class="upload" />
</div>
Step 2. CSS: Tricky Part
.fileUpload {
position: relative;
overflow: hidden;
margin: 10px;
}
.fileUpload input.upload {
position: absolute;
top: 0;
right: 0;
margin: 0;
padding: 0;
font-size: 20px;
cursor: pointer;
opacity: 0;
filter: alpha(opacity=0);
}
For demo see here http://geniuscarrier.com/how-to-style-a-html-file-upload-button-in-pure-css/

Use the input's label as custom upload button:
<label for="pic" class="uploadfilelabel" >upload </label>
<input type="hidden" name="MAX_FILE_SIZE" value="110000">
<input id="pic" name="pic" type="file" size="110000">
and CSS:
label.uploadfilelabel{/*custom label here*/}
input[type=file]{display:none;}
Notice that we did not display the main input button, because otherwise it will occupy space

I'm too late to answer but someone surely will find this useful in future, no need to use of Javascript or Hidden field too. If you are using Bootstrap then definitely there's no need of btn CSS as well.
#upload_file
{
display: none;
}
.btn-primary {
background-color: #007bff;
border-color: #007bff;
color: #fff;
}
.btn {
-moz-user-select: none;
border: 1px solid transparent;
border-radius: 0.25rem;
display: inline-block;
font-size: 1rem;
font-weight: 400;
line-height: 1.5;
padding: 0.375rem 0.75rem;
text-align: center;
transition: color 0.15s ease-in-out 0s, background-color 0.15s ease-in-out 0s, border-color 0.15s ease-in-out 0s, box-shadow 0.15s ease-in-out 0s;
vertical-align: middle;
white-space: nowrap;
}
<label for="upload_file" class="custom-file-upload btn btn-primary"><i class="fa fa-cloud-upload"></i> File Upload</label>
<input class="margin" type="file" formnovalidate id="upload_file" name="file" accept="*">

Here is an approximation to the button you want with css/html

Clear icon inside input text

Is there a quick way to create an input text element with an icon on the right to clear the input element itself (like the google search box)?
I looked around but I only found how to put an icon as background of the input element. Is there a jQuery plugin or something else?
I want the icon inside the input text element, something like:
--------------------------------------------------
| X|
--------------------------------------------------

Add a type="search" to your input
The support is pretty decent but will not work in IE<10
<input type="search">
Older browsers
If you need IE9 support here are some workarounds
Using a standard <input type="text"> and some HTML elements:
/**
* Clearable text inputs
*/
$(".clearable").each(function() {
const $inp = $(this).find("input:text"),
$cle = $(this).find(".clearable__clear");
$inp.on("input", function(){
$cle.toggle(!!this.value);
});
$cle.on("touchstart click", function(e) {
e.preventDefault();
$inp.val("").trigger("input");
});
});
/* Clearable text inputs */
.clearable{
position: relative;
display: inline-block;
}
.clearable input[type=text]{
padding-right: 24px;
width: 100%;
box-sizing: border-box;
}
.clearable__clear{
display: none;
position: absolute;
right:0; top:0;
padding: 0 8px;
font-style: normal;
font-size: 1.2em;
user-select: none;
cursor: pointer;
}
.clearable input::-ms-clear { /* Remove IE default X */
display: none;
}
<span class="clearable">
<input type="text" name="" value="" placeholder="">
<i class="clearable__clear">×</i>
</span>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
Using only a <input class="clearable" type="text"> (No additional elements)
set a class="clearable" and play with it's background image:
/**
* Clearable text inputs
*/
function tog(v){return v ? "addClass" : "removeClass";}
$(document).on("input", ".clearable", function(){
$(this)[tog(this.value)]("x");
}).on("mousemove", ".x", function( e ){
$(this)[tog(this.offsetWidth-18 < e.clientX-this.getBoundingClientRect().left)]("onX");
}).on("touchstart click", ".onX", function( ev ){
ev.preventDefault();
$(this).removeClass("x onX").val("").change();
});
// $('.clearable').trigger("input");
// Uncomment the line above if you pre-fill values from LS or server
/*
Clearable text inputs
*/
.clearable{
background: #fff url(http://i.stack.imgur.com/mJotv.gif) no-repeat right -10px center;
border: 1px solid #999;
padding: 3px 18px 3px 4px; /* Use the same right padding (18) in jQ! */
border-radius: 3px;
transition: background 0.4s;
}
.clearable.x { background-position: right 5px center; } /* (jQ) Show icon */
.clearable.onX{ cursor: pointer; } /* (jQ) hover cursor style */
.clearable::-ms-clear {display: none; width:0; height:0;} /* Remove IE default X */
<input class="clearable" type="text" name="" value="" placeholder="" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.5.1/jquery.min.js"></script>
The trick is to set some right padding (I used 18px) to the input and push the background-image right, out of sight (I used right -10px center).
That 18px padding will prevent the text hide underneath the icon (while visible).
jQuery will add the class "x" (if input has value) showing the clear icon.
Now all we need is to target with jQ the inputs with class x and detect on mousemove if the mouse is inside that 18px "x" area; if inside, add the class onX.
Clicking the onX class removes all classes, resets the input value and hides the icon.

Could I suggest, if you're okay with this being limited to html 5 compliant browsers, simply using:
<input type="search" />
JS Fiddle demo
Admittedly, in Chromium (Ubuntu 11.04), this does require there to be text inside the input element before the clear-text image/functionality will appear.
Reference:
Dive Into HTML 5: A form of Madness.
input type=search - search field (NEW) HTML5.

According to MDN, <input type="search" /> is currently supported in all modern browsers:
<input type="search" value="Clear this." />
However, if you want different behavior that is consistent across browsers here are some light-weight alternatives that only require JavaScript:
Option 1 - Always display the 'x': (example here)
Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
el.addEventListener('click', function(e) {
e.target.previousElementSibling.value = '';
});
});
.clearable-input {
position: relative;
display: inline-block;
}
.clearable-input > input {
padding-right: 1.4em;
}
.clearable-input > [data-clear-input] {
position: absolute;
top: 0;
right: 0;
font-weight: bold;
font-size: 1.4em;
padding: 0 0.2em;
line-height: 1em;
cursor: pointer;
}
.clearable-input > input::-ms-clear {
display: none;
}
<p>Always display the 'x':</p>
<div class="clearable-input">
<input type="text" />
<span data-clear-input>×</span>
</div>
<div class="clearable-input">
<input type="text" value="Clear this." />
<span data-clear-input>×</span>
</div>
Option 2 - Only display the 'x' when hovering over the field: (example here)
Array.prototype.forEach.call(document.querySelectorAll('.clearable-input>[data-clear-input]'), function(el) {
el.addEventListener('click', function(e) {
e.target.previousElementSibling.value = '';
});
});
.clearable-input {
position: relative;
display: inline-block;
}
.clearable-input > input {
padding-right: 1.4em;
}
.clearable-input:hover > [data-clear-input] {
display: block;
}
.clearable-input > [data-clear-input] {
display: none;
position: absolute;
top: 0;
right: 0;
font-weight: bold;
font-size: 1.4em;
padding: 0 0.2em;
line-height: 1em;
cursor: pointer;
}
.clearable-input > input::-ms-clear {
display: none;
}
<p>Only display the 'x' when hovering over the field:</p>
<div class="clearable-input">
<input type="text" />
<span data-clear-input>×</span>
</div>
<div class="clearable-input">
<input type="text" value="Clear this." />
<span data-clear-input>×</span>
</div>
Option 3 - Only display the 'x' if the input element has a value: (example here)
Array.prototype.forEach.call(document.querySelectorAll('.clearable-input'), function(el) {
var input = el.querySelector('input');
conditionallyHideClearIcon();
input.addEventListener('input', conditionallyHideClearIcon);
el.querySelector('[data-clear-input]').addEventListener('click', function(e) {
input.value = '';
conditionallyHideClearIcon();
});
function conditionallyHideClearIcon(e) {
var target = (e && e.target) || input;
target.nextElementSibling.style.display = target.value ? 'block' : 'none';
}
});
.clearable-input {
position: relative;
display: inline-block;
}
.clearable-input > input {
padding-right: 1.4em;
}
.clearable-input >[data-clear-input] {
display: none;
position: absolute;
top: 0;
right: 0;
font-weight: bold;
font-size: 1.4em;
padding: 0 0.2em;
line-height: 1em;
cursor: pointer;
}
.clearable-input > input::-ms-clear {
display: none;
}
<p>Only display the 'x' if the `input` element has a value:</p>
<div class="clearable-input">
<input type="text" />
<span data-clear-input>×</span>
</div>
<div class="clearable-input">
<input type="text" value="Clear this." />
<span data-clear-input>×</span>
</div>

You could use a reset button styled with an image...
<form action="" method="get">
<input type="text" name="search" required="required" placeholder="type here" />
<input type="reset" value="" alt="clear" />
</form>
<style>
input[type="text"]
{
height: 38px;
font-size: 15pt;
}
input[type="text"]:invalid + input[type="reset"]{
display: none;
}
input[type="reset"]
{
background-image: url( http://png-5.findicons.com/files/icons/1150/tango/32/edit_clear.png );
background-position: center center;
background-repeat: no-repeat;
height: 38px;
width: 38px;
border: none;
background-color: transparent;
cursor: pointer;
position: relative;
top: -9px;
left: -44px;
}
</style>

I've created a clearable textbox in just CSS. It requires no javascript code to make it work
below is the demo link
http://codepen.io/shidhincr/pen/ICLBD

Since none of the solutions flying around really met our requirements, we came up with a simple jQuery plugin called jQuery-ClearSearch -
using it is as easy as:
<input class="clearable" type="text" placeholder="search">
<script type="text/javascript">
$('.clearable').clearSearch();
</script>
​
Example: http://jsfiddle.net/wldaunfr/FERw3/

If you want it like Google, then you should know that the "X" isn't actually inside the <input> -- they're next to each other with the outer container styled to appear like the text box.
HTML:
<form>
<span class="x-input">
<input type="text" class="x-input-text" />
<input type="reset" />
</span>
</form>
CSS:
.x-input {
border: 1px solid #ccc;
}
.x-input input.x-input-text {
border: 0;
outline: 0;
}
Example: http://jsfiddle.net/VTvNX/

Change the text box type as 'search' in the design mode or
<input type="search">

EDIT: I found this link. Hope it helps. http://viralpatel.net/blogs/2011/02/clearable-textbox-jquery.html
You have mentioned you want it on the right of the input text. So, the best way would be to create an image next to the input box. If you are looking something inside the box, you can use background image but you may not be able to write a script to clear the box.
So, insert and image and write a JavaScript code to clear the textbox.

Use simple absolute positioning - it's not that hard.
jQuery:
$('span').click(function(){
$('input', $(this).parent()).val('');
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
Vanilla JS:
var spans = document.getElementsByTagName("span");
function clickListener(e) {
e.target.parentElement.getElementsByTagName("input")[0].value = "";
}
for (let i = 0; i < spans.length; i++) {
spans[i].addEventListener("click", clickListener);
}
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>
<div style="position:relative; width:min-content;">
<input>
<span style="position:absolute;right:10px">x</span>
</div>

jQuery Mobile now has this built in:
<input type="text" name="clear" id="clear-demo" value="" data-clear-btn="true">

You can do with this commands (without Bootstrap).
Array.from(document.querySelectorAll('.search-field')).forEach(field => {
field.querySelector('span').addEventListener('click', e => {
field.querySelector('input').value = '';
});
});
:root {
--theme-color: teal;
}
.wrapper {
width: 80%;
margin: 0 auto;
}
div {
position: relative;
}
input {
background:none;
outline:none;
display: inline-block;
width: 100%;
margin: 8px 0;
padding: 13px 15px;
padding-right: 42.5px;
border: 1px solid var(--theme-color);
border-radius: 5px;
box-sizing: border-box;
}
span {
position: absolute;
top: 0;
right: 0;
margin: 8px 0;
padding: 13px 15px;
color: var(--theme-color);
font-weight: bold;
cursor: pointer;
}
span:after {
content: '\2716';
}
<div class="wrapper">
<div class="search-field">
<input placeholder="Search..." />
<span></span>
</div>
</div>

Here's a jQuery plugin (and a demo at the end).
http://jsfiddle.net/e4qhW/3/
I did it mostly to illustrate an example (and a personal challenge). Although upvotes are welcome, the other answers are well handed out on time and deserve their due recognition.
Still, in my opinion, it is over-engineered bloat (unless it makes part of a UI library).

I have written a simple component using jQuery and bootstrap.
Give it a try: https://github.com/mahpour/bootstrap-input-clear-button

Using a jquery plugin I have adapted it to my needs adding customized options and creating a new plugin. You can find it here:
https://github.com/david-dlc-cerezo/jquery-clearField
An example of a simple usage:
<script src='http://code.jquery.com/jquery-1.9.1.js'></script>
<script src='http://code.jquery.com/ui/1.10.3/jquery-ui.js'></script>
<script src='src/jquery.clearField.js'></script>
<link rel="stylesheet" href="http://code.jquery.com/ui/1.10.3/themes/smoothness/jquery-ui.css">
<link rel="stylesheet" href="css/jquery.clearField.css">
<table>
<tr>
<td><input name="test1" id="test1" clas="test" type='text'></td>
<td>Empty</td>
</tr>
<tr>
<td><input name="test2" id="test2" clas="test" type='text' value='abc'></td>
<td>Not empty</td>
</tr>
</table>
<script>
$('.test').clearField();
</script>
Obtaining something like this:

No need to include CSS or image files. No need to include that whole heavy-artillery jQuery UI library. I wrote a lightweight jQuery plugin that does the magic for you. All you need is jQuery and the plugin. =)
