Yes, with some caveats. If you use a CFDUMP followed by CFABORT, the dump will be displayed whether or not the component/method has output turned off. That does, of course, abort all processing.

Not exactly (unless you're using CF9), but there are workarounds.

You can close your script, put in the dump tag, then re-open it, like so:

</cfscript><cfdump var="#myVar#"><cfscript>

There is also a UDF at CFLib that mimics the CFDUMP tag.

Dump

Added: In CF9 or later, there is also writeDump().

Coldfusion 9:

<cfscript>
    myVar = "this is a test";
    WriteDump(myVar); 
</cfscript>

Coldfusion 8 and below: CF 8 does not have a cfscript version of the tag, so if needed, it needs to be abstracted into a user defined function first. This function will need to be accessible to your component.

I avoided the name "WriteDump()" to prevent any possible conflict if this code is used with CF9.

<!--- Abstract cfdump tag for use in cfscript --->
<cffunction name="scriptDump" output="no" hint="Abstracts cfdump for cfscript">
    <cfargument name="myVar" required="yes">
    <cfset var result = "">

    <cfsavecontent variable="result">
        <cfdump var="#arguments.myVar#">
    </cfsavecontent>

    <cfreturn result>
</cffunction>

<cfset myVar = "this is a test">

<!--- Test the scriptDump(var) function in cfscript --->
<cfscript>
    dumpOfMyVar = scriptDump(myVar);
</cfscript>

<!--- Test the scriptDump(var) function in regular HTML --->
<cfoutput>
    #scriptDump(myVar)#
</cfoutput>

回答3:

cfdump inside cfcomponent? why not... But I think you should do it in a cffunction.

cfdump inside cfscript? WriteDump() in CF9, or search cflib for a UDF that works in CF6+

回答4:

You can only use writeDump in CF9. If you're in CF8, use this:


adminapi = createObject("component","cfide.adminapi.base");
adminapi.dump(foo);
