【网摘】将图片地址直接 转为 base64

$(function() {

function getBase64Image(img) { //转换为 base64 地址
var canvas = document.createElement("canvas");
canvas.width = img.width;
canvas.height = img.height;
var ctx = canvas.getContext("2d");
ctx.drawImage(img, 0, 0, img.width, img.height);
var ext = img.src.substring(img.src.lastIndexOf(".") + 1).toLowerCase();
var dataURL = canvas.toDataURL("image/" + ext);
return dataURL;
};
var imgLink = getUserInfo(account); //imgURl 原有图片地址 getUserInfo(account) 得到原有图片地址
var tempImage = new Image();
tempImage.src = imgLink;
tempImage.crossOrigin = "*";
tempImage.onload = function() {
base64ImgURL = getBase64Image(tempImage);
console.log(base64ImgURL)
}
});
