我怎样才能将其转换为 Uint8Array?Art*_*org 5 所以你有一个二进制流(我假设这些值是从某种字节数组发送的,0-255)。在将window.btoa(...)其转换为Uint8Array. 您只需迭代索引Object's(存储在从 0 开始递增的键值中)并设置 Uint8Array 的值,获取每个索引处的字符代码,并将该索引处的 Uin8Arra
首先,将内存文件对象转换为Blob对象。内存文件对象可以是一个ArrayBuffer、Uint8Array、或者字符串等。如果是字符串,可以使用TextEncoder将其转换为Uint8Array。 创建一个URL对象,使用URL.createObjectURL()方法将Blob对象转换为URL。 创建一个隐藏的<a>标签,并设置其href属性为之前创建的URL。 设置<a>标签的download属...
// Return a string representation of the range toString: function() { return "(" + this.from + "..." + this.to + ")"; } }; // Here are example uses of this new Range class let r = new Range(1,3); // Create a Range object; note the use of new...
const code = ` var a = 'hello world' `; const options = { stringArray: true, rotateStringArray: true, stringArrayEncoding: true, // 'base64' 或 'rc4' 或 false stringArrayThreshold: 1, }; 运行结果如下: var _0x4215 = ["aGVsbG8gd29ybGQ="]; (function (_0x42bf17, _0x4c348...
jsCopy to Clipboard let myFunc; if (num === 0) { myFunc = function (theObject) { theObject.make = "Toyota"; }; } 除了上述的定义函数方法外,你也可以在运行时用 Function 构造函数从一个字符串创建一个函数,很像 eval() 函数。 当一个函数是一个对象的属性时,称之为方法。了解更多关于对象...

Interactive API reference for the JavaScript Int8Array Object. Int8Array is similar to an Array where each item is an 8 bit (1 byte) signed integer. Int8Arrays cannot change size after creation.
new TypedArray(length); new TypedArray(typedArray); new TypedArray(object); new TypedArray(buffer [, byteOffset [, length]]); where TypedArray() is one of: Int8Array(); Uint8Array(); Uint8ClampedArray(); Int16Array(); Uint16Array(); Int32Array(); Uint32Array(); Float32Array(); Fl...

function saveAs(obj, filename) { var link = document.createElement("a"); link.download = filename; link.href = URL.createObjectURL(obj); link.click(); URL.revokeObjectURL(obj); } saveAs(blob, "out.xlsx"); 原理就是,把write方法输出的数据,用s2ab方法转为Uint8Array 对象,然后通过new Blo...
