在 javascript/jquery 中将 base64 转换为图像

问题描述

我已经编写了一些使用 javascript/jquery 进行图像捕获的代码下面是代码:

I have written some code for image capturing using javascript/jquery Below is the code:

function capture_image(){ 
    alert("capture_image");
    var p = webcam.capture();
    webcam.save();           
    alert("capture complete "+p); //getting true here


     var img = canvas.toDataURL("image");
    var item_image = img.replace(/^data:image/(png|jpg);base64,/, "") ; 
    alert("item_image"+item_image);
}

item_image 打印 base64 格式，如何将该 base64 转换为图像以及如何在 javascript 客户端中使用该路径.

The item_image print the base64 format, How to convert that base64 to image and how to use that path in javascript clientside.

我正在谷歌搜索这么多网站，但它无法正常工作，并且该代码不适合我的要求.

Am searching google so many websites but its not working and that code is not suitable for my requirement.

推荐答案

你可以只创建一个 Image 对象并将 base64 作为它的 src，包括 >data:image... 部分 像这样:

You can just create an Image object and put the base64 as its src, including the data:image... part like this:

var image = new Image();
image.src = 'data:image/png;base64,iVBORw0K...';
document.body.appendChild(image);

这就是他们所说的数据 URI"，这里是 兼容性表，让您内心平静.

It's what they call "Data URIs" and here's the compatibility table for inner peace.
