### jQuery
|
||||
|
||||
`jQuery.ajax` (`$.ajax`) does not support binary data out of the box. A custom
|
||||
`ajaxTransport` can add required functionality. SheetJS users have reported
|
||||
success with `jquery.binarytransport.js`.
|
||||
|
||||
After including the main `jquery.js` and `jquery.binarytransport.js` scripts,
|
||||
`$.ajax` will support `dataType: "binary"` and `processData: false`.

|
||||
|
||||
In a GET request, the default behavior is to return a `Blob` object. Passing
|
||||
`responseType: "arraybuffer"` returns a proper `ArrayBuffer` object in IE10:
|
||||
|
||||
```js
|
||||
$.ajax({
|
||||
type: "GET", url: "https://sheetjs.com/pres.numbers",
|
||||
|
||||
/* suppress jQuery post-processing */
|
||||
// highlight-next-line
|
||||
processData: false,
|
||||
|
||||
/* use the binary transport */
|
||||
// highlight-next-line
|
||||
dataType: "binary",
|
||||
|
||||
/* pass an ArrayBuffer in the callback */
|
||||
// highlight-next-line
|
||||
responseType: "arraybuffer",
|
||||
|
||||
success: function (ab) {
|
||||
/* at this point, ab is an ArrayBuffer */
|
||||
// highlight-next-line
|
||||
var wb = XLSX.read(ab);
|
||||
|
||||
/* do something with workbook here */
|
||||
var ws = wb.Sheets[wb.SheetNames[0]];
|
||||
var html = XLSX.utils.sheet_to_html(ws);
|
||||
$("#out").html(html);
|
||||
}
|
||||
});
|
||||
```
|
||||

||||
### Wrapper Libraries

Before `fetch` shipped with browsers, there were various wrapper libraries to
