38 /* Microsoft failed to properly
39 * implement the XMLHttpRequest in IE7 (can't request local files),
40 * so we use the ActiveXObject when it is available
41 * Additionally XMLHttpRequest can be disabled in IE7/IE8 so

52 JSZipUtils.getBinaryContent = function(path, callback) {
54 * Here is the tricky part : getting the data.
55 * In firefox/chrome/opera/... setting the mimeType to 'text/plain; charset=x-user-defined'
56 * is enough, the result is in the standard xhr.responseText.
57 * cf https://developer.mozilla.org/En/XMLHttpRequest/Using_XMLHttpRequest#Receiving_binary_data_in_older_browsers
58 * In IE <= 9, we must use (the IE only) attribute responseBody
59 * (for binary data, its content is different from responseText).
60 * In IE 10, the 'charset=x-user-defined' trick doesn't work, only the
61 * responseType will work :
62 * http://msdn.microsoft.com/en-us/library/ie/hh673569%28v=vs.85%29.aspx#Binary_Object_upload_and_download
64 * I'd like to use jQuery to avoid this XHR madness, but it doesn't support
65 * the responseType attribute : http://bugs.jquery.com/ticket/11461
