TextEncoder()

这是一个实验中的功能
此功能某些浏览器尚在开发中,请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订,所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

The TextEncoder() 构造函数返回一个新创建的TextEncoder对象。

语法

encoder = new TextEncoder(); 

参数

  • TextEncoder() 从 Firefox 48 and Chrome 53 开始不再需要参数

Note: 在Firefox 48和Chrome 53之前,编码类型标签被接受为TextEncoder对象的参数,现在这两个浏览器已经删除了除utf-8之外的任何编码器类型的支持,以符合规范。 传入TextEncoder构造函数的任何类型标签现在都将被忽略,并且将创建一个utf-8 TextEncoder。

  • 旧的参数:
