hey there i'm making a simple webpage which requires to download an output image file at the last step..
but i don't know how can i add download button dynamically at correct time, because at starting of a page there is no need of download button..
so i have main.js file:
which looks something looks like this:
let img_code=document.getElementById('img_code');
let textbox=document.getElementById('textbox');
let gen_button_img=document.getElementById("img_button");
gen_button_qr.addEventListener("click",()=>
{
var trailer=textbox.value;
var url='www.example.com';
var result= url.concat(trailer);
if (navigator.onLine)
{
if(trailer.length<=1725 && trailer.length>0)
{
if((trailer !="0")&& (trailer.replace(/\s/g, '').length))
{
image_code.src=result;
alert("Image Generated successfully");
/**/
}
else
{
alert("You cannot create this file spaces only or only with single 0");
}
}
else
{
alert("Maximum charecter limit is exceeded!! ");
}
}
else
{
alert("No Internet Connection");
}
});
So, i have the question is there any way to dynamically add the button which takes file URL as input and download that file through web browser's downloader?
Note=>
I can easily save the result by right click on the picture and save image option; but i want to add an extra button to download the same file.
Most of the things explained in comments so read it first
// arrow function to create and append download button into any element
// it only takes url of file that will download.
const createBtn = (URL) => {
// create button element
const downloadBtn = document.createElement("button");
// you can set any name of id according to your choice
downloadBtn.setAttribute("id", "downloadBtn");
// create anchor element
const downloadLink = document.createElement("a");
// set any thing in inner text
downloadBtn.innerText = "Download Image";
// set download attribute to true
downloadLink.setAttribute("download", true);
// set url with URL
downloadLink.setAttribute("href", URL);
// append button element into anchor element
downloadLink.appendChild(downloadBtn);
// get that element in which download button will append
const container = document.getElementById("container");
// append download button into any element of your choice
container.appendChild(downloadLink);
};
// url of file
const URL = "https://images.pexels.com/photos/863963/pexels-photo-863963.jpeg?cs=srgb&dl=pexels-blaque-x-863963.jpg&fm=jpg"
// call createBtn function with URL
createBtn(URL);
<!-- The element in which download button will be appended -->
<div class="container" id="container"></div>
I am not 100% sure that this will work!
It also not work in stack snippet because iframe tag.
Try to use it locally.
I'm trying to write in javascript and I want to understand why it doesn't work?
sample order code that I want to copy: 593004485164756431
when I copy to clipboard : 593004485164756500
I checked for an error in the console, there was no error, does the browser affect the error? i use firefox
this my code
function copyToClipboard(text) {
if (navigator.clipboard && window.isSecureContext) {
return navigator.clipboard.writeText(text)
} else {
// text area method
let textArea = document.createElement("textarea")
textArea.value = text
// make the textarea out of viewport
textArea.style.position = "fixed"
textArea.style.left = "-999999px"
textArea.style.top = "-999999px"
document.body.appendChild(textArea)
textArea.focus()
textArea.select()
return new Promise((res, rej) => {
// here the magic happens
document.execCommand('copy') ? res() : rej()
textArea.remove()
})
}
}
on button
<img onclick="copyToClipboard({{ $result['code_order'] }})" style="width:20px;cursor:pointer;" src="{{ url('img/copy-solid.svg') }}"/>
I hope I can find the solution to this problem. Thank you
Seemingly, you can't (yet) programmatically copy an image to the clipboard from a JavaScript web app?
I have tried to copy a text in clipboard , and it's worked.
Now I would like to copy an image and after I press ctrl+v to paste into Word or Excel or Paint.
$(function() {
$("#btnSave").click(function() {
html2canvas($("#container1"), {
onrendered: function(canvas) {
theCanvas = canvas;
document.body.appendChild(canvas);
Canvas2Image.saveAsPNG(canvas);
$("#img-out").append(canvas);
}
});
});
});
For those still looking, the ClipboardAPI now works with png images.
try {
navigator.clipboard.write([
new ClipboardItem({
'image/png': pngImageBlob
})
]);
} catch (error) {
console.error(error);
}
This worked across all browsers (as of 2016). I have uploaded on GitHub as well: https://github.com/owaisafaq/copier-js
//Cross-browser function to select content
function SelectText(element) {
var doc = document;
if (doc.body.createTextRange) {
var range = document.body.createTextRange();
range.moveToElementText(element);
range.select();
} else if (window.getSelection) {
var selection = window.getSelection();
var range = document.createRange();
range.selectNodeContents(element);
selection.removeAllRanges();
selection.addRange(range);
}
}
$(".copyable").click(function(e) {
//Make the container Div contenteditable
$(this).attr("contenteditable", true);
//Select the image
SelectText($(this).get(0));
//Execute copy Command
//Note: This will ONLY work directly inside a click listenner
document.execCommand('copy');
//Unselect the content
window.getSelection().removeAllRanges();
//Make the container Div uneditable again
$(this).removeAttr("contenteditable");
//Success!!
alert("image copied!");
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="copyable">
<img src="https://via.placeholder.com/80" alt="Copy Image to Clipboard via Javascript." />
</div>
<div class="copyable">
<img src="https://via.placeholder.com/80" alt="Copy Image to Clipboard via Javascript." />
</div>
So, i created the perfect solution with 1 liner-kinda solution to convert something with html2canvas to a canvas and then produce the image of it and then save it to clipboard as png. For example,
HTML:
<div id="copyToImage">Hello World!</div>
JavaScript:
$("#copyToImage").click(function() {
html2canvas(document.querySelector("#copyToImage")).then(canvas => canvas.toBlob(blob => navigator.clipboard.write([new ClipboardItem({'image/png': blob})])));
});
You are right. There is no support to copy image data into clipboard in chrome yet. https://bugs.chromium.org/p/chromium/issues/detail?id=150835.
Looks like it has been open for about 4 years now.
There is a clipboard API spec that is coming up though
https://w3c.github.io/clipboard-apis/
Well, this is my first post in here with an answer i guess :)
Actually i'm currently using cefsharp web browser component one of my project, cefsharp run on chrome based browser and i want to copy img element one of webpage
With cefsharp you can manipulate browser only javascript, so i think we can handle it with using canvas element.
/*
'cause of lorempixel timeout, i used img onload function.
*/
function copyImage() {
var imgCap = document.getElementById('imgCap');
var imgCanvas = document.createElement('canvas');
imgCanvas.id = 'imgCanvas';
imgCanvas.height = 40;
imgCanvas.width = 120;
document.body.appendChild(imgCanvas);
var originalContext = imgCanvas.getContext('2d');
originalContext.drawImage(imgCap, 0, 0);
//return imgCanvas.toDataURL();
}
//document.onload = copyImage();
<img id="imgCap" src="http://lorempixel.com/120/40" onload="copyImage();"/>
with return imgCanvas.toDataURL(); you can get base64 encoded value and use wherever you want.
this is my cefsharp code, it's working.
string copyImageOtClipboardScript = "(function(){ try{var imgCap = document.getElementById('imgCap'); var imgCanvas = document.createElement('canvas'); imgCanvas.id = 'imgCanvas'; imgCanvas.height = 40; imgCanvas.width = 120; document.body.appendChild(imgCanvas); var originalContext = imgCanvas.getContext('2d'); originalContext.drawImage(imgCap, 0, 0); return imgCanvas.toDataURL(); }catch(e){ alert(e); } })();";
var task = chromeBrowser.EvaluateScriptAsync(copyImageOtClipboardScript).ContinueWith(x =>
{
var resp = x.Result;
if (resp.Success)
{
this.Invoke((MethodInvoker)delegate
{
Bitmap bmp = null;
string captchaResult = "", captchaBase64;
var bytes = Convert.FromBase64String(resp.Result.ToString().Replace("data:image/png;base64,", ""));
using (var imageFile = new FileStream("temp_captcha.png", FileMode.Create))
{
imageFile.Write(bytes, 0, bytes.Length);
imageFile.Flush();
}
});
}
});
This can be achieved by using the Clipboard API, which does require that your server is secured. The basic idea is to convert your image to a blob before writing it to the clipboard as an image.
const img = document.querySelector("#b64-img");
const copyBtn = document.querySelector("#copy");
copyBtn.onclick = e => {
const canvas = document.createElement("canvas");
canvas.width = img.width;
canvas.height = img.height;
canvas.getContext("2d").drawImage(img, 0, 0, img.width, img.height);
canvas.toBlob((blob) => {
navigator.clipboard.write([
new ClipboardItem({ "image/png": blob })
]);
}, "image/png");
};

This will allow you to paste your image to Photoshop and other image-applications.
Check out this guide to copying and pasting with JavaScript: https://www.lucidchart.com/techblog/2014/12/02/definitive-guide-copying-pasting-javascript/
According to this, Chrome, Safari, and Firefox all support copying images along with plain text, while IE only allows copying text. The page linked above describes how this service uses an extension to add this functionality to a context menu, but it appears that several browsers support programmatic copying of images.
const copyImageToClipboard = async () => {
try {
await navigator.clipboard.write([
new ClipboardItem({
'image/png': await fetch(img).then((r) => r.blob()),
}),
]);
} catch (error) {
console.error(error);
}
};
You might run into CORS errors testing on localhost. But you can install a CORS extension to get rid of that issue :)
var image = new Image();
image.src = url;
copyImageToClipboard(image.src);
install it from https://www.npmjs.com/package/copy-image-clipboard
Here is the best answer i found for you, very simple and its working 100% exactly what you need.
await navigator.clipboard.writeText(code);
Check out this link: enter link description here
You cannot copy to clip board with Javascript for security reasons, a work around can be found in a discussion here. Involves flash.Click button copy to clipboard using jQuery

I Got Answer by Implementing WebChromeClient In android
let webview: WebView = this.webViewRef.nativeElement;
let myWebChromeClient: MyWebChromeClient = new MyWebChromeClient();
webview.android.setWebChromeClient(myWebChromeClient);
and class MyWebChromeClient is here
import * as imagepicker from "nativescript-imagepicker";
import * as fs from "file-system";
export class MyWebChromeClient extends android.webkit.WebChromeClient {
file_path:string;
constructor() {
super();
return global.__native(this);
}
onShowFileChooser(webView,filePathCallback,fileChooserParams) {
this.filepathCallback(filePathCallback);
return true;
}
filepathCallback(filePathCallback)
{
let context = imagepicker.create({
mode: "single",
mediaType: imagepicker.ImagePickerMediaType.Any
});
this.startSelection(context,filePathCallback);
}
startSelection(context,filePathCallback) {
context.authorize().then(() => {
return context.present();
})
.then((selection) => {
selection.forEach((selected) => {
let path = selected.android;
let file = fs.File.fromPath(path);
this.file_path = file.path;
this.file_path = "file://" + this.file_path;
let results = Array.create(android.net.Uri, 1);
results[0] = android.net.Uri.parse(this.file_path);
filePathCallback.onReceiveValue(results);
return this.file_path;
});
}).catch(function (e) {
console.log(e);
});
}
}
