![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L21lX25ldmVy_size_16_color_FFFFFF_t_70_pic_center]

id3v2的属性值太多了，就不截图了，想看直接去[官网][Link 1]看

我们的代码业务一般就是读取展示属性值以及id3v1和id3v2的区分，直接看代码。

binaryajax.js和id3.js的git 地址：[https://github.com/bailyxu/js\_demol.git][https_github.com_bailyxu_js_demol.git]

    	var file2 = "Ìïð¥Õç - 04.²»×í²»»á.mp3";
    
    	//id3v1文件
    	var file1 = "11.025kHz_64Kbps_DC(2.5).mp3";
    
        ID3.loadTags(file, ()=> { 
            var fileContent = ID3.getAllTags(file)
            console.log(fileContent);
            $("#id3").text(JSON.stringify(fileContent, null, 4));
        });
    
        ID3.loadTags(file2, ()=> { 
            var fileContent = ID3.getAllTags(file2)
            console.log(fileContent);
            $("#id2").text(JSON.stringify(fileContent, null, 4));
        });
    
        ID3.loadTags(file1, ()=> { 
            var fileContent = ID3.getAllTags(file1)
            console.log(fileContent);
            $("#id1").text(JSON.stringify(fileContent, null, 4));
        });
    </script>
    </body>
    </html>

输出结果：
