更多SQLITE教程请查看https://www.runoob.com/sqlite/sqlite-data-types.html SQLite 数据类型是一个用来指定任何对象的数据类型的属性。SQLite 中的每一列，每个变量和表达式都有相关的数据类型。 您可以在创建表的同时使用这些数据类型。SQLite 使用一个更普遍的动态类型系统。在 SQLite 中，值的数据类型与值本身是相关的，而不是与它的容器相关。 SQLite 存储类 每个存储在 SQLite 数据库中的值都具有以下存储类之一： 存储类 描述 NULL 值是一个 NULL 值。 INTEGER 值是一个带符号的整数，根据值的大小存储在 1、2、3、4、6 或 8 字节中。 REAL 值是一个浮点值，存储为 8 字节的 IEEE 浮点数字。 TEXT 值是一个文本字符串，使用数据库编码（UTF-8、UTF-16BE 或 UTF-16LE）存储。 BLOB 值是一个 blob 数据，完全根据它的输入存储。 SQLite 的存储类稍微比数据类型更普遍。INTEGER 存储类，例如，包含 6 种不同的不同长度的整数数据类型。 SQLite 亲和(Affinity)类型 SQLite支持列的亲和类型概念。任何列仍然可以存储任何类型的数据，当数据插入时，该字段的数据将会优先采用亲缘类型作为该值的存储方式

As typeof returns "object".. var MyBlob = new Blob(['test text'], {type : 'text/plain'}); console.log(typeof MyBlob) // "object" is it too early to ask for a generic solution for checking whether or not a variable is a blob as it is not yet widely supported? Or how should I go about testing for blob type in browsers which already have it implemented? You can test if it is an instanceof Blob like this: var MyBlob = new Blob(['test text'], {type : 'text/plain'}); console.log(MyBlob instanceof Blob) // true jsFiddle: http://jsfiddle.net/jfriend00/5xkgd/ This will work for things that inherit from
