Question

How does IE7's "View Source" button interact with javascript?

Answer 1

+8 A:

What you see with "view source" is the raw HTML that has been fetched. The HTML doesn't include any changes that were done via DHTML/JavaScript.

Update

Inspired by Manik's comment, here's a cross-browser¹ bookmarklet to display what's rendered inside <body>:

javascript:"<pre>"+document.body.innerHTML.replace(/([&<>])/g,function(c){return"&"+{"&":"amp","<":"lt",">":"gt"}[c]+";";})+"</pre>"

¹ Doesn't seem to work on Safari though. Anyone know why?

Yup, and if you want to see the rendered source, create a bookmark with this as the URL: javascript:'<xmp>'%20+%20window.document.body.outerHTML+%20'</xmp>'

@Manik: nice! Note that <xmp> is deprecated and <pre> should be used instead (after escaping the HTML characters)

@Manik: Also outerHTML is not standard. We'll have to make do with innerHTML and just see what's inside <body>...

+4 A:

If you want to see what effect the javascript is having on your page, use IE8 or FireFox/Firebug on the page to see what it is(not) doing.

They will also give you information on the Css Style, if the case is actually that the wrong element is displayed, and the right one is hidden.

Answer 3

+2 A:

As mentioned already "View Source" will display the HTML sent by the server, modifications made via JavaScript will not be reflected in the "View Source".

I would suggest looking for any JavaScript code that might be modifying the value of the "RecurrenceProperties_TextBox57" text box. Check the <script type="text/javascript"></script> areas of the source for any code that references the text box.

Answer 4

+1 A:

If it's me, first thing I'd do is disable javascript and load the page. That'll narrow down where your error is coming very quickly, especially if you suspect javascript to be at fault.

AS far as what the view source is doing, it's showing you what the browser is interpreting...the code as it was sent from the server. None of that code is executed in the view source.
