Consider test.cfm file with the following content:
<html>
<body>
<cfif foo EQ bar>
<cfset test = "something" />
</cfif>
<p>Hello!</p>
</body>
</html>
When run in the browser, the source code of the output of this file will look like this:
<html>
<body>
<p>Hello!</p>
</body>
</html>
Is there any way to fix this?
There’s nothing to fix – the HTML is perfectly valid and functional.
If your issue is the size of request, use gzip encoding.
If your issue is reading the source for debugging/etc, use developer tools such as Firebug/etc.
However, general things you should be doing to improve maintainability (which at the same time also reduces whitespace output) are:
1) Move anything that isn’t display logic out of your views.
2) Convert display logic to functions and custom tags as appropriate, which both make it easier to prevent/control output.
To prevent unwanted content being output, you can:
Wrap the entire section in cfsilent, to ensure nothing gets output.
Enable
enablecfoutputonlyattribute of cfsetting then only use cfoutput around things you want to be output.Always set
output=falseon component and function tags.When you want to selectively output some text, wrap non-tag non-output segments in CFML comments
<!---…--->(e.g. useful for preventing newline output in custom tags)(I never bother with cfprocessingdirective, everything mentioned above solves the issues better.)
