## 语法

    dataview.getUint32(byteOffset [, littleEndian])

### 参数

byteOffset
  偏移量, 单位为字节, 从头开始计算.
littleEndian
  可选 Indicates whether the 32-bit int is stored in little- or big-endian format. If false or undefined, a big-endian value is read.

### 返回

  一个无符号长整型32位数.

### 抛出错误

`RangeError`
  如果byteOffset超出了视图能储存的值，就会抛出错误.

## 描述

  没有对齐约束; 多字节值可以从任何偏移量获取.

## 例子

    var buffer = new ArrayBuffer(8);
    var dataview = new DataView(buffer);
    dataview.getUint32(1); // 0
