[solved] using switch inside a loop?

gkaefer · January 4, 2012 at 2:28 AM

Code

switch(testit, 2, 1, 2, 1);
	if(	get(testit),
		trace('test it: ',get(testit));
		switch(testit, 2, 1, 2, 1);
		);

is it possible to give a variable "testit" several values and than to work with these different values inside a loop.
in my example, if all values of the variable are print on logwindow than exit/end the loop?
(above code does not work)... or is the switch(variable, value1, value2, value3) etc.only usable for oncklick events and similar?

many thanks in advance!
Liebe Gruesse,

I created followin action, but why do I get 9 x NULL instead of the values of the switch?

Code

<action name="testit">
		showlog();
		trace('--- action: ',%0,' ---');
		set(var1,1); set(var2,9);
		loop( 	var1 LE var2,
			switch(testit,9,8,7,6,5,4,3,2,1);
			trace('test it(',get(var1),'): ',get(testit) );
			inc(var1);
			);
	</action>

output:

Code

INFO: --- action: testit ---
INFO: test it(1): null
INFO: test it(2): null
INFO: test it(3): null
INFO: test it(4): null
INFO: test it(5): null
INFO: test it(6): null
INFO: test it(7): null
INFO: test it(8): null
INFO: test it(9): null

Hi,

the switch action can only change existing variables!

so just set/create the "testit" variable first,
e.g.

Code

<action name="test">
	showlog();
	trace('--- action: ',%0,' ---');
	set(var1,1); 
	set(var2,9);
	set(testit,1);
	loop( 	var1 LE var2,
		switch(testit,9,8,7,6,5,4,3,2,1);
		trace('test it(',get(var1),'): ',get(testit) );
		inc(var1);
		);
</action>

thank you, Klaus - working now.

is it possible to assign the switch values via external variable, like:

<plugin...
var2="1,2,3,4,5,67,8,9";
../plugin>

<action...
set(testit,1);
switch(testit, get(plugin[..].var2));
.../action>

vorab besten Dank!

Hi,

Quote from gkaefer

is it possible to assign the switch values via external variable

only by using a second action,

e.g.

Code

<action name="myswitch">
switch(%1, %2);
</action>


...
myswitch(testit, get(...));

best regards,
Klaus

so far all is clear, but it does not work on my side.
it seems that after the switch the %1 cant be accessed anymore:

Code

<settings name="themevars"
	slideshow-show-panos-order="1,3,7,4,9"
/>


<plugin name="myplugin"
	(...)
	onloaded="	myswitch(testit2, get(settings[themevars].slideshow-show-panos-order));
		"
/>


<action name="myswitch">
	showlog();
	trace('--- action: ',%0,' ---');
	set(var1,1); 
	set(var2,5);
	loop( 	var1 LE var2,
		switch(%1, %2);
		trace('myswitch 1(',get(var1),'): ', %1 );
		trace('myswitch 2(',get(var1),'): ', '%2' );
		trace('myswitch  (',get(var1),'): ', get(testit2) );
		inc(var1);
	);
</action>

the traceoutput shows me that %1 and %2 are correct loaded by myswitch
but I cant access the %1 with its correct variable name after the switch, get(testit2) gives me null...
I also tried to use '%2' inside the switch ... same result.

Code

INFO: --- action: myswitch ---
INFO: myswitch 1(1): testit2
INFO: myswitch 2(1): 1,3,7,4,9
INFO: myswitch  (1): null
INFO: myswitch 1(2): testit2
INFO: myswitch 2(2): 1,3,7,4,9
INFO: myswitch  (2): null
INFO: myswitch 1(3): testit2
INFO: myswitch 2(3): 1,3,7,4,9
INFO: myswitch  (3): null
INFO: myswitch 1(4): testit2
INFO: myswitch 2(4): 1,3,7,4,9
INFO: myswitch  (4): null
INFO: myswitch 1(5): testit2
INFO: myswitch 2(5): 1,3,7,4,9
INFO: myswitch  (5): null

Hi,

the variable must exists first!
switching/changing a variable that doesn't exits is not possible,

best regards,
Klaus

oh man,

seems that "sitting on the line" is a my new hobby.

many thanks,
Liebe Grüße,

the working code and the result:

Code

<settings name="themevars"
	slideshow-show-panos-order="5,9,12,2,1"
/>


<plugin name="myplugin"
	(...)
	onloaded="	set(testit2,1); 
			myswitch(testit2, get(settings[themevars].slideshow-show-panos-order));
		"
/>


<action name="myswitch">
	showlog();
	trace('--- action: ',%0,' ---');
	set(var1,1); 
	set(var2,5);
	loop( 	var1 LE var2,
		switch(%1, %2);
		trace('myswitch (',get(var1),'):  ', %1 );
		inc(var1);
	);
</action>

the result:

Code

INFO: --- action: myswitch ---
INFO: myswitch (1):  5
INFO: myswitch (2):  9
