add

QRCodeModel.prototype = {
        // ...
        make: function () {
            if (this.typeNumber < 1) {
                var typeNumber = 1;
                for (typeNumber = 1; typeNumber < 40; typeNumber++) {
                    var rsBlocks = QRRSBlock.getRSBlocks(typeNumber, this.errorCorrectLevel);

                    var buffer = new QRBitBuffer();
                    var totalDataCount = 0;
                    for (var i = 0; i < rsBlocks.length; i++) {
                        totalDataCount += rsBlocks[i].dataCount;
                    }

                    for (var i = 0; i < this.dataList.length; i++) {
                        var data = this.dataList[i];
                        buffer.put(data.mode, 4);
                        buffer.put(data.getLength(), QRUtil.getLengthInBits(data.mode, typeNumber));
                        data.write(buffer);
                    }
                    if (buffer.getLengthInBits() <= totalDataCount * 8)
                        break;
                }
                this.typeNumber = typeNumber;
            }
            this.makeImpl(false, this.getBestMaskPattern());
        }
        // ...

modify

    QRCode.prototype.makeCode = function (sText) {
        this._oQRCode = new QRCodeModel(-1, this._htOption.correctLevel);
        this._oQRCode.addData(sText);
        this._oQRCode.make();
        //this._el.title = sText;
        this._oDrawing.draw(this._oQRCode);
        this.makeImage();
    };

remove _getTypeNumber definition and usage.

Same error. This seems to happen when URL contains some URLEncoded parts. Can you explain your fix ?

@axtux
I didn't really looked into these codes, but it really works.
I found it here, which I was using years ago, and it always works.

It just seems that qrcode.min.js is not up to date. Getting qrcode.js and minify it yourself is working.
