Using an Image File, I am getting the url of an image, that needs be to send to a webservice. From there the image has to be saved locally on my system.
The code I am using:
var imagepath = $(“https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg#imageid”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg).val();// from this getting the path of the selected imagethat var st = imagepath.replace(data:image/png or jpg; base64″https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg/”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg);How to convert the image url to BASE64?

Basically, he implemented this function:
function toDataUrl(url, callback) { var xhr = new XMLHttpRequest(); xhr.onload = function() { var reader = new FileReader(); reader.onloadend = function() { callback(reader.result); } reader.readAsDataURL(xhr.response); }; xhr.open(“https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpgGET”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg, url); xhr.responseType = “https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpgblob”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg; xhr.send();}And in your case, you can use it like this:
toDataUrl(imagepath, function(myBase64) { console.log(myBase64); // myBase64 is the base64 string});
This is your html-
Javascript should be-
var can = document.getElementById(“https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpgimgCanvas”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg); var img = document.getElementById(“https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpgimageid”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg); var ctx = can.getContext(“https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg2d”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg); ctx.drawImage(img, 10, 10); var encodedBase = can.toDataURL();”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpgencodedBase”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg Contains Base64 Encoding of Image.
const getBase64FromUrl = async (url) => { const data = await fetch(url); const blob = await data.blob(); return new Promise((resolve) => { const reader = new FileReader(); reader.readAsDataURL(blob); reader.onloadend = function() { const base64data = reader.result; resolve(base64data); } });}getBase64FromUrl(“https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpghttps://lh3.googleusercontent.com/i7cTyGnCwLIJhT1t2YpLW-zHt8ZKalgQiqfrYnZQl975-ygD_0mOXaYZMzekfKW_ydHRutDbNzeqpWoLkFR4Yx2Z2bgNj2XskKJrfw8″https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg).then(console.log)
You Can Used This :
function ViewImage(){ function getBase64(file) { return new Promise((resolve, reject) => { const reader = new FileReader(); reader.readAsDataURL(file); reader.onload = () => resolve(reader.result); reader.onerror = error => reject(error); });}var file = document.querySelector(“https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpginput

I try using the top answer, but it occur Uncaught DOMException: Failed to execute “https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpgtoDataURL”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg on “https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpgHTMLCanvasElement”https://obatambeienwasirherbal.com/convert-image-to-base64-jquery/imager_6_21997_700.jpg: Tainted canvases may not be exported.
I found this is because of cross domain problems, the solution is
