No ArrayBuffer in IE9 ( and possibly below )

[furoTmark]

When trying out the examples in Internet Exolorer 9 this exception comes up:
Error in function : 'ArrayBuffer' is undefinedReferenceError: 'ArrayBuffer' is undefined

The block of code that gives the error is on line 803:

    getArrayBuffer = function() {
        var data = buildDocument(), len = data.length,
        ab = new ArrayBuffer(len), u8 = new Uint8Array(ab);

        while(len--) u8[len] = data.charCodeAt(len);
        return ab;
    },

Added https://github.com/inexorabletash/polyfill/blob/master/typedarray.js for ArrayBuffer, but still get:

Error in function : Object expectedTypeError: Object expected

This seems a problem on the polyfill, probably a limitation on the implementation for your specific browser, so i'd report it on their repo.

I have this same issue, and unfortunately most of our users (which are mostly corporations) are using IE 9.

Go to this page in IE 9: http://mrrio.github.io/jsPDF/
The current behavior is a javascript alert: "Error in function : 'ArrayBuffer' is undefined

If the jsPDF library requires some other libraries to work in IE 9, it may be a good idea to list those dependencies on the README.md

Good idea. Something like this perhaps:

Not sure how performant this is.

Here is another one:

https://github.com/inexorabletash/polyfill/blob/master/typedarray.js

However, I had to modify this because there is a maximum array size of 100,000 which I increased to 1,000,000

I'm having the same issue when I try to save a PDF - I took in https://github.com/inexorabletash/polyfill/blob/master/typedarray.js as a polyfill for ArrayBuffer and am now getting the "Error in function : Object expected" error in IE 9. Tracked it down to line 423 of jspdf.js (I have a version downloaded from the Parallax site rather than downloaded from here), if you look at what fn is at line 410, it's cut off in IE 9 but not in Chrome.

i.e. IE 9:

function(type, options) {
            switch (type) {
                case undefined:
                    return buildDocument();
                case 'save':
                    if (navigator.getUserMedia) {
                        if (global.URL === undefined
                        || global.URL.createObjectURL === undefined) {
                            return 

Whereas in Chrome, it's the full function. Therefore in IE it stops at the unfinished return statement at the end, as it's expecting an Object, just as the error message says...that's what I think is happening.

Additionally, IE 9 is missing implementations of atob and Blob, which I have found polyfills for:

https://github.com/carlo/jquery-base64
https://github.com/eligrey/Blob.js

Possibly relevant issues on the typedarray.js polyfill Github:

• Uint8Array crashes IE9 Uint8Array crashes IE9 inexorabletash/polyfill#7
• typedarray.js the browser stop responding typedarray.js the browser stop responding inexorabletash/polyfill#17
