[OpenLayers-Users] 2 questions - custom control.button not firing & xmlhttprequest issue

[David Hollema]

I'm new to OL and working on a project to display digital photos in a
browser using the OL API.  I'd like to use a few custom control.buttons
added to a control.panel.  Trouble is the trigger function is not firing
when I click the custom button on the UI.  Here's the code.

 

var clearPicksBtn = new OpenLayers.Control.Button({trigger:
clearPicks(pointLayer), displayClass: "clearPicksBtn",

 
title:'Clear all picks'});

                                                                

                                                                var
prevPhotoBtn = new OpenLayers.Control.Button({trigger: f_slideshow(-1),
displayClass: "prevPhotoBtn",

 
title:'Previous photo'});

                                                                

                                                                var
nextPhotoBtn = new OpenLayers.Control.Button({trigger: f_slideshow(1),
displayClass: "nextPhotoBtn",

 
title:'Next photo'});

                                                                

                                                                //var
panel = new OpenLayers.Control.Panel({div:
document.getElementById("panel")});

                                                                var
panel2 = new OpenLayers.Control.Panel({div:
document.getElementById("panel2"), defaultControl: panCustom});

                                                                

                                                                

 
panel2.addControls([panCustom, zb, history.next, history.previous,
drawPtControl, 

 
dragPtControl, clearPicksBtn, prevPhotoBtn, nextPhotoBtn]);

 
map.addControl(panel2);

 

 

 

Next question.  I'm trying to load a OpenLayers.Layer.Text layer stored
locally on our network.  I am not publishing my web page using a web
server, it's simply running the html and javascript off a network .html
file served over the file network.  Trouble is I get an access denied
error from IE7 when opening a layer file even if it's in the same path
as the html file.  Is there a work around?

 

//var newl = new OpenLayers.Layer.Text( "text", {location:
"c://temp//test.txt"} );

 
//map.addLayer(newl);

 

Any help is appreciated.
