JavaScript: Invoking The SaveAs Dialog From A Web Page

INFORMATION:
============

INSTRUCTIONS:
=============

Step 1.: The Script
-------------------

Insert the following script in the head of the page:

// Source: CodeFoot.com
// Please leave in this header.

var isReady = false;
function doSaveAs(){
if (document.execCommand){
if (isReady){document.execCommand("SaveAs");}
}else{
alert('Feature available only in Internet Exlorer 4.0 and later.');
}
}

</script>

Step 2.: The Body Tag Interlock
-------------------------------

Include the following onload event call in the body tag.  This stops
the script from functioning until the page is fully loaded.

Step 3.: The Link
-----------------

To call the script from the page and activate the SaveAs dialog, 
insert a link in the page like this:

<a href="javascript:doSaveAs()">
Click Here To Save This Page
</a>

Comments

See the instructions in the script for installation directions. Try the popup demo (above) to exercise the script.

IE4+ browsers provide a document.execCommand() that can call certain system dialogs. This script demonstrates calling the SaveAs dialog to save a web page. The script includes onload interlocking and alternate alert messaging for non-IE browsers.

Note that the script can only be used to save the current page; that is, the page in which the script is included.
