Javascript variable into loadpano call

I'm trying to pass the current frame into a loadpano call within Javascript and am not sure what I am doing wrong. My guess is my syntax. Any suggestions?

Thanks!

This is the trigger:

Source code

 
1

<td><center><img src="preview/10.png" width="65" height="65" onclick="getframe();loadobject('10.xml');" /><br>10.xml</center></td>


This is the function that get's the current frame number (which I have tested by getting a value in a HTML text field.

Source code

7
8
9

	function getframe()
		{
			var frame = Number( viewer().get("image.frame") );
			
			document.getElementById("frame").innerHTML = frame;
			
		}


This does not work, meaning the image.frame parameter is not feeding my Javascript frame variable from the getframe() function:

Source code

 
1
2
3
4

	function loadobject(xmlname)
	{
		viewer().call("loadpano(" + xmlname + ", image.frame=frame , MERGE, BLEND(1));");
	}

Passing a value works but...

Passing the image.frame value explicitly (value is 36 in this example) in the loadobject() call initiated from onlick works as it should:

Source code

 
1

<td><center><img src="preview/08.png" width="65" height="65" onclick="getframe();loadobject('08.xml',36);" /><br>08.xml</center></td>


This is the embed code I used and the getframe() and loadobject() functions:

var swf = createswf("viewer.swf", "viewerSWFObject", "100%", "500", "#FFFFFF");
	swf.addVariable("xml", "01.xml");
	swf.embed("viewerDIV");
	
	
	
	function viewer() 
	{
		return document.getElementById("viewerSWFObject");
	}
	
	function getframe()
		{
			var frame = viewer().get("image.frame") ;
			
			document.getElementById("frameplace").innerHTML = frame;  
			
		}
	
	
	function loadobject(xmlname,myframe)
	{
		viewer().call("loadpano(" + xmlname + ", image.frame=" + myframe +" , MERGE, BLEND(1));");
	}



But trying to pass the javascript frame variable into the loadpano call fails. I can get the current image frame number using the getframe() function, but there is something odd about passing this to the loadpano call.

I also tried this with no luck:

<td><center><img src="preview/08.png" width="65" height="65" onclick="getframe();loadobject('08.xml',frame);" /><br>08.xml</center></td>

function loadobject(xmlname,myframe)
	{
		viewer().call("loadpano(" + xmlname + ", image.frame=" + myframe +" , MERGE, BLEND(1));");
	}


and this:


Source code

4

function loadobject(xmlname,frame)
	{
		viewer().call("loadpano(" + xmlname + ", image.frame=" + frame +" , MERGE, BLEND(1));");
	}


Does a loadpano call need to be constructed before it is called - and if so how come passing an explicit variable works but trying to pass something stored in Javascript does not?

I'm going crazy here!

Hi Macio,

In my opinion your code is correct...

Can you post a link to see what is going wrong?

SAlut.

Hi Michel,

I finally figured this out. It was a scoping issue. This works (look at the loadobject function):

Source code

 
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15

17

	var swf = createswf("viewer.swf", "viewerSWFObject", "100%", "500", "#FFFFFF");
	swf.addVariable("xml", "01.xml");
	swf.embed("viewerDIV");
	
	
	
	function viewer() 
	{
		return document.getElementById("viewerSWFObject");
	}
	
	
	function loadobject(xmlname,myframe)
	{
		var myframe = viewer().get("image.frame"); 
		viewer().call("loadpano(" + xmlname + ", image.frame=" + myframe +" , MERGE, BLEND(1));");
	}


The variable myframe has to be declared inside the loadobject function in order for it to be available to the loadpano call. I suppose it could have also been declared outside the loadobject function, but it has to be done explicitly using the var statement.


I am now having a problem replicating this using xml code. The following DOES NOT work (but I am getting results from both trace(myframe) commands in debug mode):

Source code

 
1
2

		<action name="my_load_pano">
			set(myframe,get(image.frame));
			trace(myframe);
			loadpano(%1,image.frame=myframe,KEEPALL,BLEND(0.5));wait(blend);
			trace(myframe);
		</action>


This triggers the above:

Source code

<plugin name="object_01"
		url="preview/08.png"
		scale="1"
		edge="center"	
		align="lefttop"
		x="75"
		y="60"
		onclick="action(my_load_pano,08.xml)"
		onhover=""
		onover=""
		onout =""	
		/>



The following also does NOT work:

Source code

 
1

loadpano(08.xml,image.frame=get(image.frame),KEEPALL,BLEND(0.5));wait(blend);



This on the other hand works (as it should):

Source code

 
1

loadpano(08.xml,image.frame=36,KEEPALL,BLEND(0.5));wait(blend);


I am starting to suspect that there is something specific about the way the loadpano() call or function gets assembled and the way in which it accepts variables.

Hi Macio,

I thing you can not use a get() action inside the vars parameter of the loadpano() action...
So, instead of:

Source code

 
1

loadpano(08.xml,image.frame=get(image.frame),KEEPALL,BLEND(0.5));wait(blend);


try to construct the loadpano() using a txtadd():

Source code

 
1
2
3

txtadd(temp,'loadpano(08.xml,image.frame=',get(image.frame),',KEEPALL,BLEND(0.5))');
call(temp); <!-- this line calls the constructed loadpano() -->
wait(blend);


Hope this help *smile* ...

SAlut.

Thanks Michel !

I was starting to think I would have to construct the call as text first (just like your example) and the execute it. Your code works perfectly!


However I think that there also must be a way of passing a variable rather than a fixed value into the vars of loadpano().


Thank you again *cool*
