saveas execCommand with own interface

I would like to use execCommand('saveas') but not have the dialog box pop up.

I know by putting execCommand(SaveAs, false, tempcontent.php); perhaps would work, but it doesn't seem to in my code. I figure the format of the filename can't be right or something.  

Can anyone give me a clue as to what the filename should be. I do want it to be exactly the same everytime this command is used, but I don't really care what it is called, as long as I know.

Thanks,
H

It is not possible to avoid the prompt.  That would be a security breach since you could overwrite an important systen file.

This link shows a workaround:
      http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=UTF-8&selm=unUk16U0CHA.428%40TK2MSFTNGP09

It uses the FileSystemObject to save the HTML.   Since that is an ActiveX object, the user will be proyed about using "unsafe objects" so there is still a prompt.

Best to just let the prompt come up.  The user will be promyed, but he will neeed only click the [OK] button.  It is always good to let the user know that you are saving data to his hard disk.

function DoTest() {
      document.execCommand( 'saveas', false, "c:\\temp\\pg.htm" )
}

I don't want to save it to the user's hard disk. I want to save it to a directory hosted at the location of the website.  

What I need is a way of getting all of the data in the editable area and saving it to a file or to a variable.  It doesn't have to be the saveas command, I just thought that would be a handy way of getting all of the data in the editable area, I need the html code to be saved somehow.

Do you have any other suggestions on how I can do it. I don't want the user to be prompted though. They will press the save button and this will start the process. If I wanted a prompt I would create my own to fit with the design of the page.

Thanks,
H

If you want to allow the user to upload a file to your server, that is an entriely different issue!

Just use
<FORM method=post ENCTYPE="multipart/form-data" action=your_url >
        <input type=file name="TheFile">
</FORM>

in your HTML.  It displays a textbox and a [Browse...] button.

See:
http://msdn.microsoft.com/workshop/author/dhtml/reference/objects/input_file.asp

The server will need to be able to handle uploads, but all servers can do that these days.

The problem is that I have no way of collecting the data. Originally I display it by outputting two variables, one with the css and one with the main html, but as soon as I make a change the variables no longer hold the data. The only way I can think of getting the data back, is by using an execCommand function to save it or select it and somehow copy it. The data is not in a form it is just held within a <div></div>

I don't understand you last comment at all.  First you want to know how to download a file and then you want to know how to upload a file, and now there is something about variables and <div> tags....

If you need to maintiain some information on the client machine, the way to do that is to create and save a "cookie"  Use the

     document.cookie

object to do that.  See:
      http://msdn.microsoft.com/workshop/author/dhtml/reference/properties/cookie.asp

I need to somehow save the data which is held in an editable area of a page. I thought this could be done using the saveas function, but apparently not, as I can't do that without a dialog box popping up. So I am now looking for other ways of getting the information.

There is another execCommand which is called selectall. I was considering using this and then somehow getting the selected part into a variable or file. Can this be done?

I already use cookies but it isn't really relevant to what I am doing in this bit.

Sorry I'm struggling to explain exaclty what I'm doing. Thanks for keeping with it.

You won't be able to save a file to the user's hard disk without a prompt.  And you won't be able to read that data without a warning prompt.

(exception:  If the page is a local HTML file -- not one sent by a server -- then you can write it as a HTA (Hypertext Application) and the the user will not be prompted about unsafe operations sich as saving files).

Note that the max length of a cookie appears to be 4K (though it might vary by the browser), so unless you have a great deal of data to save, you might look a little bit deeper into using cookies.

If a cookie won't work, then the normal technique would be to post the data back to the server and then, when the user needs that data, the server sends it back to the client.
