Save file in html

Then you will need to save the exercise's code as a file and give it a specific name and file extension. The file name you give it will always start with the exercise name's first three characters, followed by an underscore, and then ending with your last name. For example:. For the text files of the html source code we will use the file extension. When this extension is used a Web browser will readily identify the file as an html file and open it.

Without it, or with a different extension, things probably won't go so smoothly. You will be asked to save the files in Windows' accessory text editing program Notepad, using Notepad's default format: text. However, you will need to manually add the file extension.

You must always remember to manually add this extension. Otherwise Notepad will automatically add the. If that does happen to you, simply rename the file, which you ought to know how to do. First we need to create two folders to contain the files you save: one for all the html files and one for all the image files.

The images folder will go inside the html folder. Use the following steps Mac users: use the Finder and New Folder in place of the options below :. You ought to now have a folder called exercises and within it a folder called images. As we do the exercises, save all of your html files in the exercises folder and all of your image files in the images folder.

If you don't save your image files in the images folder, the exercises won't work properly. Save your files on the hard drive, but also back up on a floppy disk, zip disk, or USB flash card if I instruct you to do so. Any files that are left on a school hard drive are subject to deletion. It doesn't happen often, but is has happened.

I already have the code to parse the file in JavaScript, so I may as well use it as my exporter too! The problem is saving. Now, I know that I can parse the file, send the result to the server, and have the browser request the file back from the server as a download. But in reality the server has nothing to do with this particular process, so why get it involved? I already have the contents of the desired file in memory. Is there any way that I could present the user with a download using pure JavaScript?

I doubt it, but might as well ask And to be clear: I am not trying to access the filesystem without the users knowledge! The user will provide a file probably via drag and drop , the script will transform the file in memory, and the user will be prompted to download the result. All of which should be "safe" activities as far as the browser is concerned. Though it's a perfectly valid answer for anyone doing a "real" web app.

That being the case it looks like I'm out of luck unless I want to involve the server. Thanks anyway! Here is basically how I do it:. There will be length limitations depending on browser type etc. Firefox 3. Encoding in Base64 instead using encodeURIComponent might make things more efficient, but for me that was ok. HTML5 defined a window. It isn't supported by any browser right now. But there is a compatibility library called FileSaver. Internet Explorer 10 supports a navigator.

I wrote a blog posting with more details about this problem. Long data URIs can give performance problems in browsers. Another option to save client-side generated files, is to put their contents in a Blob or File object and create a download link using URL. This returns an URL that can be used to retrieve the contents of the blob.

The blob is stored inside the browser until either URL. Most web browsers have support for object URLs , Opera Mini is the only one that does not support them.

If the data is text or an image, the browser can open the file, instead of saving it to disk. To cause the file to be downloaded upon clicking the link, you can use the the download attribute. However, not all web browsers have support for the download attribute. See also ' Force to open "Save As The filename can also be specified as the argument to the download attribute, but this is subject to a ton of security considerations.

Internet Explorer 10 and 11 provides its own method, msSaveBlob , to specify a filename. For example, I did this function to export logs displayed on a page. You have to pass an array for the instanciation of the Blob, so I just maybe didn't write this the right way, but it works for me. Just in case, be careful with the replace: this is the syntax to make this global, otherwise it will only replace the first one he meets.

You can generate a data URI. However, there are browser-specific limitations. I found two simple approaches that work for me. First, using an already clicked a element and injecting the download data. And second, generating an a element with the download data, executing a. But the second approach works only if invoked by a user click action as well. Some Browser block click from other contexts like on loading or triggered after a timeout setTimeout.

If you want to download binary data look here. Here is a link to the data URI method Mathew suggested, it worked on safari, but not well because I couldn't set the filetype, it gets saved as "unknown" and then i have to go there again later and change it in order to view the file You can use localStorage.

This is the Html5 equivalent of cookies. That is, testing directly on my home computer didn't work. I'm working up HTML5 examples. The information to re-build the maze is stored using localStorage.

Is it the same as older html and JavaScript???? Here are simple examples of how the APIs are used, directly and indirectly, in tandem to do this:. Though the FileSystem and FileWriter APIs are no longer on the standards track, their use can be justified in some cases, in my opinion, because:.

This thread was invaluable to figure out how to generate a binary file and prompt to download the named file, all in client code without a server. First step for me was generating the binary blob from data that I was saving. There's plenty of samples for doing this for a single binary type, in my case I have a binary format with multiple types which you can pass as an array to create the blob.

The next step is to get the browser to prompt the user to download this blob with a predefined name. I kept it hidden since the link doesn't need display. When testing the "ahref" method, I found that the web developer tools of Firefox and Chrome gets confused. I needed to restart the debugging after the a. Same happened with the FileSaver it uses the same ahref method to actually make the saving.

Change the type of the file to "All Files" and add ". Not Helpful 5 Helpful 1. Once the HTML file has been saved, plug-in the pendrive. Then, open up File Explorer and select your file.
