Basically as you can see in the code I tried to set it to 1000px wide just to show its not changing the size at all it wont go any bigger I can make it smaller but not wider. I added some spacing so you can see what I am talking about easier.
The Snippet asked for
#Html.TextAreaFor(x => x.businessJustification, new { id = "businessJustification", name = "businessJustification", #cols = 40, #rows = 3,#style="width: 1000px;"}) </p>

I have provided a image of how small the "1000px" wide box is and if I set this to like 200px it is also the same size.
i have a navbar and i want to scroll it horizontally. I use "Tab" and "Tabs" from react-bootstrap. I couldn't figure out how to do this. ( I tried to wrap nav with div, but it didn't work because every tab has its own items )
I tried this:
const outsider = document.getElementsByClassName('products-tabs sub-tabs nav nav-tabs');
const distance = 200;
const scrollLft = () => {
outsider.scrollLeft -= 900;
console.log(outsider);
};
<Tab
className="products-tab"
id="products-tab"
eventKey={index}
title={subcategories.categoryName}
key={`${index + 1}_tab`}
>
{subcategories?.subcategories?.length > 1 ? (
<>
<Button onPress={scrollLft} className="brand-arrow-button">
<i className="icon-Arrow_Simple_left" align="left" />
</Button>
<Button
onPress={() => onClickLeft()}
className="brand-arrow-button-right"
>
<i className="icon-Arrow_simple_rightt" align="left" />
</Button>
<div id="menum">
<Tabs
className="products-tabs sub-tabs"
defaultActiveKey="sub-0"
id="menu-subcategories"
onSelect={e => {
const selectedTabIndex = parseInt(e.split('-')[1], 10);
setActiveSubcategory(selectedTabIndex);
}}
>
{subcategories?.subcategories
?.concat(subcategories?.subcategories)
.map((subcategoryItem, subIndex) => (
<Tab
eventKey={'sub-' + subIndex}
title={subcategoryItem?.name}
key={`${subIndex + 1}_subTab`}
>
**Items
</Tab>
))}
</Tabs>
And this is my css:
&.sub-tabs {
border-radius: 15px;
margin-left: -1px;
margin-right: -16px;
padding-bottom: 1px;
margin-top: 10px;
flex: none;
overflow-x: scroll;
white-space: nowrap !important;
When i click to the button, nothing happens.
This is the console output:
enter image description here
In React, you can use the useRef() Hook to get the reference of a component (similar to document.getElementsByClassName()). Then, you can apply horizontal scrolling using element.current.scrollLeft.
Example:
import { useRef } from 'react'
const App = () => {
const scrollElement = useRef(null)
const scrollLeft = () => {
scrollElement.current.scrollLeft = 50
}
return (
<div className = 'App'>
<div className = 'ScrollMenu' ref = {scrollElement}>
<a href = '#home'>Home</a>
<a href = '#news'>News</a>
<a href = '#contact'>Contact</a>
<a href = '#about'>About</a>
</div>
<button onClick = {scrollLeft}>Click me</button>
</div>
)
}
Here is a live example.
I tried to set an onClick event to open a flexbox in react using tsx. The button and the flexbox is shown properly but vscode shows a problem with the onClick event. I cant figure out whats wrong but maybe you can. I am new to the field and tried some ideas from the stack community but it didnt work for me.
The console tells me I have to assign 'string' but it doesnt work either.
//Function to change visibility of the flexBox
document.getElementById("OpenProfiles")
.addEventListener("click", ProfilesOpn);
function ProfilesOpn () {
var a = document.querySelectorAll(".ProfilesOpen")[0];
var b = document.querySelectorAll(".ProfilesClose")[0];
a.style.visibility = "hidden"
b.style.visibility = "visible";
}
//the button code inside the flexbox
<div className={"Profiles"}>
<div className={"Profile1"}>
<div className={"Profile1P"}></div>
<h3 className={"ProfileH3"}>Profile1</h3>
</div>
<div className={"Profile2"}>
<div className={"Profile2P"}></div>
<h3 className={"ProfileH3"}>Profile2</h3>
</div>
<div className={"Profile3"}>
<div className={"Profile3P"}></div>
<h3 className={"ProfileH3"}>Profile3</h3>
</div>
<div className={"Profile4"}>
<div className={"Profile4P"}></div>
<h3 className={"ProfileH3"}>Profile4</h3>
</div>
<h3 className={"EndCoPro"}>Are you missing any profiles?</h3>
<button id="OpenProfiles" onClick="return(ProfilesOpn());">
<div className={"ProfilesOpen"}><img src={ProfilesOpen} alt="Open Profiles"/></div>
</button>
</div>
//the code in sass for the styling
.Profiles {
position: absolute;
display: flex;
left: 0px;
bottom: 0px;
width: 300px;
height: 900px;
flex-direction: column;
justify-content: flex-start;
align-items: space-between;
background-color: #292929;
box-shadow: 0px 0px 5px 0px rgba(0, 0, 0, 0.2);
border-top-right-radius: 25px;
border-bottom-right-radius: 25px;
visibility: hidden;
}
Code Sandbox: https://codesandbox.io/s/dazzling-bouman-62hgi?file=/src/App.js:0-1850
Here are 2 approaches to what you are trying to accomplish using react hooks:
The ProfilesOpn function uses a ref to set DOM properties.
The reactWayToShowCat function sets the showCat status using internal component state.
import React, { useState, useRef } from "react";
import "./styles.css";
export default function Explorer() {
const a = useRef(null);
const b = useRef(null);
const [showCat, toggleShowCat] = useState(true);
const ProfilesOpn = () => {
a.current.style.visibility = "hidden";
b.current.style.visibility = "visible";
};
const reactWayToShowCat = () => {
toggleShowCat(!showCat);
};
return (
<div className="Profiles">
{Array(4)
.fill("")
.map((_, i) => {
const num = i + 1;
return (
<div className={`Profile${num}`} key={num}>
<div className={`Profile${num}P`}></div>
<h3 className="ProfileH3">{`Profile${num}`}</h3>
</div>
);
})}
<h3 className="EndCoPro">Are you missing any profiles?</h3>
<button id="OpenProfiles" onClick={ProfilesOpn}>
<div className={"ProfilesOpen"} ref={a}>
<img src="https://placekitten.com/200/300" alt="Open Profiles" />
<p>
Click to see solution that uses refs to accomplish what you were
doing
</p>
</div>
</button>
<button id="CloseProfiles" onClick={reactWayToShowCat}>
<div className={"ProfilesClose"} ref={b}>
<>
{showCat && (
<img src="https://placekitten.com/200/300" alt="Close Profiles" />
)}
<p>
Click to see one react way to show and hide the cat (no styling)
</p>
</>
</div>
</button>
</div>
);
}
The main issue in original code was that onClick needs to be set with this syntax:
<button id="OpenProfiles" onClick={ProfilesOpn}>
Hope this helps!
I want to add a show password button inside of the password input field.
I am using crispy forms for styling so I am a little bit stuck on the best practice here.
Currently I have a seperate checkbox field which is showing the password on check. Js is working fine here.
I'd like to change de checkbox to a eye icon which is inside of the input field.
I've managed to add the eye icon to the input field via css background: url(path-to-icon).
I can't figure out how to change the icon to a button (1) and add my js to it (2).
My form:
class CustomSignupForm(SignupForm):
user_group = forms.ModelChoiceField(queryset=Group.objects.exclude(name='admin').exclude(name='personeel').exclude(name='onderhoud'),
widget=forms.RadioSelect(attrs={'placeholder': 'Soort klant:'}),
initial=('particulier'), label='Soort klant'
)
first_name = forms.CharField(max_length=30,
label='Voornaam',
widget=forms.TextInput(attrs={'placeholder': 'Voornaam'}),)
last_name = forms.CharField(max_length=30,
label='Achternaam',
widget=forms.TextInput(attrs={'placeholder': 'Achternaam'}),)
My HTML :
<div class="form-row">
<div class="form-group col-md-6 mb-0">
<a>{{ form.password1 | as_crispy_field}}</a>
</div>
<div class="form-group col-md-6 mb-0">
<a>{{ form.password2 | as_crispy_field}}</a>
</div>
</div>
<div class="form-row">
<div class="form-group col-md-12 mb-0">
<input class="ml-2" type="checkbox" onclick="ShowPassword()"> show password
</div>
</div>
My css:
#id_password1 {
background: url("http://127.0.0.1:8000/static/user/media/eye_icon.png") no-repeat;
background-size: 20px 20px;
background-position: right;
background-position-x: 97%;
}
#id_password2 {
background: url("http://127.0.0.1:8000/static/user/media/eye_icon.png") no-repeat;
background-size: 20px 20px;
background-position: right 10px;
background-position-x: 97%;
}
My js :
function ShowPassword() {
var x = document.getElementById("id_password");
if (x.type === "password") {
x.type = "text";
} else {
x.type = "password";
}
}
Does anyone have any ideas to make this work?
Did you try font awesome ?
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css">
Add this to base.html
<button class="btn"><i class="fa fa-eye"></i></button>
Add this where ever you'd like to place the icon.
.btn{
cursor: pointer;
}
.btn-hover{
background-color:YourChoice;
}
Add this to your css file accordingly .
Thanks! Made this work properly only need to make a custom input field with the button inside of the field via the crispy form helper. Can't figure out how to do this though. Got something like this right now:
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.layout = Layout(
Field('password1', on_click="ShowPassword()")
)
My working button right now:
<input type="image" class="ml-2" src="/static/user/media/eye_icon.png" onclick="ShowPassword()" id="show-password-button">
You could try :
Field(
PrependedText('password',mark_safe('<span class ="glyphicon glyphicon-eye-open"></span>'), placeholder=_("Enter Password")))
Made it almost!
Did everything in HTML, CSS and JS.
HTML
<a>{{ form.password2 | as_crispy_field}}</a>
<button class="toggle-password ml-2 fa fa-eye"></button>
CSS
.toggle-password {
position: absolute;
top: 50%;
right: 6%;
width: 20px;
height: 20px;
border: none;
background-color: transparent;
}
HTML
$("body").on('click','.toggle-password',function(){
var $pass1 = document.getElementById("id_password1");
var $pass2 = document.getElementById("id_password2");
var toggle = $(this).toggleClass("fa-eye fa-eye-slash");
[$pass1, $pass2].forEach(function($passwords) {
if ($passwords.type === "password") {
$passwords.type = "text";
toggle.toggleClass()
} else {
$passwords.type = "password";
}
})
});
Still figuring out how to make both icons toggle at the same time. Now they doing it seperately.
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');

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">

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>

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);
});
