Sadly there is no pure Javascript solution (and working in every browsers) to this. However...</p> - - <h4>Solution-ish: <a href="https://github.com/dcneiner/downloadify">Downloadify</a></h4> - <p>Downloadify uses a small Flash SWF to download files to a user's computer with a filename that you can choose. Doug Neiner has added the <code>dataType</code> option to allow you to pass a zip for downloading. Follow the <a href="http://downloadify.info/downloadify/test.html">Downloadify demo</a> with the following changes:</p> - <pre class="example"> -zip = new JSZip(); -zip.file("Hello.", "hello.txt"); -Downloadify.create('downloadify',{ -... - data: function(){ - return zip.generate(); - }, -... - dataType: 'base64' -});</pre> - - <h4>Other solution-ish: Blob URL</h4> - <p>With <a href="http://caniuse.com/bloburls">some recent browsers</a> come a new way to download Blobs (a zip file for example) : blob urls. The <a href="http://updates.html5rocks.com/2011/08/Downloading-resources-in-HTML5-a-download">download attribute on <a></a> allows you to give the name of the file. Blob urls start to be widely supported but this attribute is currently only supported in Chrome and Firefox (>= 20). See <a href="examples/download-zip-file.html">the example</a>.</p> - <pre class="example"> -var blob = zip.generate({type:"blob"}); -myLink.href = window.URL.createObjectURL(blob); -myLink.download = "myFile.zip";</pre> - - <h3>Usage with Google Gears</h3> - <p> - <a href="http://www.picurl.org/blog/author/franz/">Franz Buchinger</a> has written a brilliant tutorial on <a href="http://www.picurl.org/blog/2009/11/22/creating-zip-archives-with-gears/">using JSZip with Google Gears</a> (<a href="http://www.picurl.org/blog/2009/11/29/gearszipper-part2-adding-support-for-real-files-and-canvas-elements/">part 2</a>). If you want to let your Gears users download several files at once I really recommend having a look at some of his <a href="http://picurl.org/gears/zipper/">examples</a>.</p> - - <h3>Reading a zip file from an ajax call</h3> - <p> - When doing an ajax call to get the binary data, the browser will try to interpret the binary as text, corrupting it. The solution is to <a href="https://developer.mozilla.org/En/XMLHttpRequest/Using_XMLHttpRequest#Receiving_binary_data_in_older_browsers">set the mimetype to 'text/plain; charset=x-user-defined'</a>. This solution works well in all browsers but IE. If you need IE support, please see what is done in the file test/index.html. - </p> - <p>An other solution is to use a modern browser (supporting <a href="http://caniuse.com/xhr2">xhr2</a>) : setting <code>xhr.type = 'arraybuffer';</code> will do the trick, JSZip supports ArrayBuffers. Please see <a href="examples/get-binary-files-xhr2.html">the example</a>. - - <h3>Reading a local zip file (File API)</h3> - <p> - JSZip supports (if available in the browser) the File API : reading a local zip file is simple : <code>new JSZip(readerEvent.target.result);</code>. Please see the <a href="examples/read-local-file-api.html">complete example</a> for more details. - </p> - - <h2 style="margin-top: 2em;">Documentation</h2> - - <h4 id="doc_new_JSZip">new JSZip()</h4> - <dl> - <dt>Description : </dt> - <dd>The default constructor.</dd> - <dt>Returns : </dt> - <dd>A new JSZip.</dd> - </dl> - - <h4 id="doc_new_JSZip_data_options">new JSZip(data [,options])</h4> - <dl> - <dt>Description : </dt> - <dd>Create a new JSZip file and load an existing zip file.

ZIP64 uses 64bits integers - but Javascript represents all numbers as - <a href="http://www.ecma-international.org/publications/files/ECMA-ST/ECMA-262.pdf"> - 64-bit double precision IEEE 754 floating point numbers</a> (see section 8.5). - So, we have 53bits for integers and - <a href="https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Operators/Bitwise_Operators"> - bitwise operations treat everything as 32bits</a>. - So if all the 64bits integers can fit into 32 bits integers, everything will be fine. If - it's not the case, you will have other problems anyway (see next limitation). - </p> - <h4>Performance issues</h4> - <p> - An other limitation comes from the browser (and the machine running the browser). - A compressed zip file of 10MB is "easily" opened by firefox/chrome/opera/IE10 but - will crash older IE. Also keep in mind that strings in javascript are encoded in UTF-16 : - a 10MB ascii text file will take 20MB of memory. - </p> - <p> - If you're having performance issues, please consider the following : - <ul> - <li>Don't use IE < 10. Everything is better with WebGL support.</li> - <li> - If you load the file from an ajax call, ask your XHR an ArrayBuffer. - Loading a string is asking for troubles. - </li> - <li> - If you want to get the content of an ASCII file as a string, consider using - <code>asBinary()</code> instead of <code>asText()</code>. The transformation - "binary string" -> "utf string" is a consuming process. - </li> - </ul> - </p> - <h4>The output zip will differ from the input zip</h4> - <p> - Reading and generating a zip file won't give you back the same file. - Some data are discarded (file metadata) and other are added (subfolders). - </p> - - <h2>Changelog</h2> - <h3>1.0.1 <span>2013-03-04</span></h3> - <ul> - <li>Fixed an issue when generating a compressed zip file with empty files or folders, - see <a href="https://github.com/Stuk/jszip/pull/33">#33</a>.</li> - <li>With bad data (<code>null</code> or <code>undefined</code>), asText/asBinary/asUint8Array/asArrayBuffer methods - now return an empty string, see <a href="https://github.com/Stuk/jszip/pull/36">#36</a>.</li> - </ul> - <h3>1.0.0 <span>2013-02-14</span></h3> - <p> - First release after a long period without version. - </p> - - <h2 id="migrating_guide">Migrating Guide</h2> - <h3>From 1.0.x to ?</h3> - <p> - <ul> - <li><code>JSZipBase64</code> has been renamed to <code>JSZip.base64</code>.</li> - <li> - The <code>data</code> attribute doesn't exist anymore : - use the getters <code>asText()</code>, <code>asBinary()</code>, etc - </li> - <li> - The compression/decompression methods now give their input type with the - <code>compressInputType</code> and <code>uncompressInputType<code> attributes. - </ul> - - Example for the data attribute : - <pre>// before -zip.file("test.txt").data; -zip.files["test.txt"].data; - -// after -zip.file("test.txt").asText(); -zip.files["test.txt"].asText(); - </p> - </div> - - <div id="who" class="grid_3"> - <h2>Anything else?</h2> - - <h3>License</h3> - <p> - <a href="https://github.com/Stuk/jszip/blob/master/LICENSE.markdown">MIT license or GPLv3</a> - </p> - - <h3>Version</h3> - <p>1.0.1</p> - <p>See the <a href="#migrating_guide">migrating guide</a> when updating the library !</p> - - <h3>Todo</h3> - <ul> - <li>Set correct version needed to extract</li> - <li>Set correct version made by</li> - <li>Set internal and external file attributes in central directory</li> - <li>Allow setting of attributes/other info in <code>add()</code> options object</li> - <li>Look into using <a href="http://www.phpied.com/mhtml-when-you-need-data-uris-in-ie7-and-under/">MHTML</a> for IE</li> - </ul> - - <h3>Who?</h3> - <p><a href="http://stuartk.com">Stuart Knightley</a>, with contributions from:</p> - <ul> - <li><a href="http://www.picurl.org/blog/author/franz/">Franz Buchinger</a></li> - <li><a href="http://www.aadsm.net/">António Afonso</a></li> - <li><a href="http://github.com/dduponchel">David Duponchel</a></li> - <li><a href="http://yiminghe.javaeye.com">yiminghe</a></li> - </ul> - - <h3>Contact and bugs</h3> - <ul> - <li><a href="https://github.com/Stuk/jszip/issues">Issue tracker</a></li> - <li><a href="mailto:stuart -at- stuartk.com?subject=JSZip">Email me</a></li> - </ul> - </div> - -</div> - -</body> -</html> -<!-- vim: set shiftwidth=3 softtabstop=3: --> |
