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.

Base64 是一组相似的二进制到文本(binary-to-text)的编码规则。一个常见应用是对二进制数据进行编码,以便将其纳入dataURL中。 在JavaScript 中,有两个函数被分别用来处理解码和编码 Base64 字符串: atob():解码通过 Base-64 编码的字符串数据(“atob”应读作“ASCII to binary”) ...
