FileReader to String

rated 0 times [ 12] [ 6] / answers: 1 / hits: 19979 / 11 Years ago, sat, february 22, 2014, 12:00:00

Consider the following code

function readSingleFile(evt) {

    //Retrieve the first (and only!) File from the FileList object

    var myFile = evt.target.files[0];

    var reader = new FileReader();

    reader.readAsText(myFile);

    var myString = reader.toString();

    alert(myString); // print  - "[object FileReader]"   

}

I try to get all the file content into String , for example if the file content is

helloWorld1

helloWorld2

I will get alert of that's content .

That's not how you get the result of a FileReader. Modify your code to this:

function readSingleFile(evt) {

        //Retrieve the first (and only!) File from the FileList object

        var myFile = evt.target.files[0];

        var reader = new FileReader();

        reader.readAsText(myFile);

        reader.onload=function(){alert(reader.result)}

    }
