IE10 Support (reader.readAsBinaryString) about sheetjs

[redchair123]

IE10 does not support readAsBinaryString. To test on IE I have been using
the Base64 method (generating the input and pasting into the text box).

FYI in this case readAsArrayBuffer is probably better.

I've also been looking for a more general solution that also works with
older IEs (using something like flash or silver light).

I have trouble reading the Uploaded File (XLSX) via FileReader API's
"readAsBinaryString" method in IE10. "readAsText" method works fine. Has
anyone come across this, does IE support this method? Am I missing
something. Pls find the snippet below:

function handleFileUpload(evt){

evt.stopPropagation();
evt.preventDefault();

var files = (evt.target.files || evt.dataTransfer.files);
var output = [];

for (var i = 0, f; f = files[i]; i++) {
output.push('

', escape(f.name), ' (', f.type || 'n/a', ') - ', f.size, ' bytes, last modified: ', f.lastModifiedDate ?
f.lastModifiedDate.toLocaleDateString() : 'n/a', '

');

var reader = new FileReader();
reader.onload = function(e) {
    var data = e.target.result;
    alert("-- Data Length --" + data.length);

};

 // Read in the XLSX file in Binary Mode.
 //reader.readAsBinaryString(f);//<-- does not work if this method is used in IE10 (10.0.9200.16540C0), but works on Chrome
   reader.readAsText(f);//<-- Works on both Chrome & IE10 (10.0.9200.16540C0)

}//for

}//handleFileUpload

@SKALIDHASAN I pushed a change so it works on IE10 (I also had to handle the 'dragenter' event). At a later time, I'll add support for older IEs
