getInt8 Method (DataView)

Gets the Int8 value at the specified byte offset from the start of the view. There is no alignment constraint; multi-byte values may be fetched from any offset.

Syntax

var testInt = dataView.getInt8(byteOffset);   

Parameters

testInt
Required. The Int8 value that is returned from the method.

byteOffset
The place in the buffer at which the value should be retrieved.

Remarks

These methods raise an exception if they would read beyond the end of the view.

Example

The following example shows how to get the first Int8 in the DataView.

var req = new XMLHttpRequest();  
    req.open('GET', "http://www.example.com");  
    req.responseType = "arraybuffer";  
    req.send();  

    req.onreadystatechange = function () {  
        if (req.readyState === 4) {  
            var buffer = req.response;  
            var dataView = new DataView(buffer);  
            alert(dataView.getInt8(0));  
        }  
    }
