Hi,
I am new to Java Script. I have a download button. When the button is clicked, I want to pop-up a File Download dialog box with the options open, save .. .I am not sure how to call the File download dialog box and also I need to download an Excel file when I click on the download button.I tried to use document.execCommand('saveas' ..). But it directly opens a Save As Html dialog and saves the html file. Can any one please explain me how to open File download dialog.
Thanks a lot !!!

When you say "download" you mean from the server to the client, correct? (If not, there is an entry in the JSP FAQ regarding file uploading that you may find helpful.)

All you need to do is to create a link to the file and make sure that your browser is set up properly to handle the MIME type of the file correctly.

If you want more control over the download, you will need to wirte a servlet (or other server-side mechanism) to handle the file streaming.

deepa, JavaRanch is a community of people from all over the world, many of who are not native English speakers. While using abbreviations like "u" instead of spelling out "you" is convenient when text messaging your friends on a cell phone or in a chat room, it presents an extra challenge to those that are already struggling with English. Additionally, such shortcuts may confound automated translation tools that patrons of the Ranch may be making use of.

I would like to ask for your help in making the content of JavaRanch a little easier to read for everybody that visits here by not using such abbreviations.

Please read this for more information.

thanks,
