Get document from Document Library using Javascript

Question

I am trying to get a document from document library.I am getting the file but I can't get its binary value.

 $.ajax({
    url: fileUrl,
    binaryStringResponseBody: true,
    headers: {
        "Accept": "application/json; odata=verbose",
        "X-RequestDigest": 'digest'
    },
    type: "GET"
})
.done(Function.createDelegate(this, readFileSuccess))
.error(Function.createDelegate(this, readFileFailure));

but it didn't give me a binary value for the file. I need to get binary value and store it to local storage ( Web SQL ).

How to get the binary value?

Answer 1

You can use success handler for reading file content

function readFileSuccess(data) {
    alert(data);
}

Update

var executor = new SP.RequestExecutor(weburl);
var info = {
    url: fileContentUrl,
    method: "GET",
    binaryStringResponseBody: true,
    success: function (data) {
        //binary data available in data.body
        var result = data.body;
    },
    error: function (err) {
        alert(JSON.stringify(err));
    }
};
executor.executeAsync(info);
