How to open the newly created image in a new tab?
提问by John Stephen
Below code creates the image in the bottom of the same page. How to display that image into a new tab/window instead of displaying in the same page?
下面的代码在同一页面的底部创建图像。如何将该图像显示到新选项卡/窗口中而不是显示在同一页面中？
success: function (data) {
var image = new Image();
image.src = "data:image/jpg;base64," + data.d;
document.body.appendChild(image);
}

something like:
就像是：
success: function (data) {
var image = new Image();
image.src = "data:image/jpg;base64," + data.d;
var w = window.open("");
w.document.write(image.outerHTML);
}

current suggestions not worling at chrome, I always getting a white page, now I using
当前的建议不在 chrome 上，我总是得到一个白页，现在我使用
const base64ImageData = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==';
const contentType = 'image/png';
const byteCharacters = atob(base64ImageData.substr(`data:${contentType};base64,`.length));
const byteArrays = [];
for (let offset = 0; offset < byteCharacters.length; offset += 1024) {
const slice = byteCharacters.slice(offset, offset + 1024);
const byteNumbers = new Array(slice.length);
for (let i = 0; i < slice.length; i++) {
byteNumbers[i] = slice.charCodeAt(i);
}
const byteArray = new Uint8Array(byteNumbers);
byteArrays.push(byteArray);
}
const blob = new Blob(byteArrays, {type: contentType});
const blobUrl = URL.createObjectURL(blob);
window.open(blobUrl, '_blank');
thanks to Jeremy!

setTimeout(function(){
