[Dynapi-Dev] Dynlayer extension: allows anchors to work within a layer.

[Jordi - IlMaestro - Ministral]

Nothing better than needing them yourself in order to contribute to the
API :).

The are two parts in the script. First you need to parse your links so
anchors are redirected to a custom javascript method. Call this one
after content has been set.

DynLayer.prototype.parseLinks = function() {
var lks
 if(is.ns4) lks = this.doc.links
 else if(is.ie) lks = this.elm.all.tags('a')
 else lks = this.elm.getElementsByTagName("a")

 for(var i=0;i<lks.length;i++) {
  var li = lks[i]
  if(li.href.indexOf("#")>=0) {
   // Anchors
   var guere = li.href.substring(li.href.indexOf("#")+1)
   li.href = "javascript:goAnchor('"+guere+"')"
  }
}

}

Now all our anchors will call a goAnchor method

function goAnchor(name) {
    myLayer.goAnchor(name,0,0,false,false)
}


And here goes the extension. Accepts additional parameters such as
position offsets ( in case you want margins ) and allows to ignore
scrolling for one coordinate.

DynLayer.getCoords = function(obj) {
 var ret = obj.offsetParent ? DynLayer.getCoords(obj.offsetParent) : {
x:0, y:0 }
 ret.x += obj.offsetLeft
 ret.y += obj.offsetTop
 return ret
}

DynLayer.prototype.goAnchor = function(name,xoff,yoff,ignoreX,ignoreY) {

 var destX = -1
 var destY = -1

 // Search for anchor position
 if(is.ie) {
  var alllinks = contenidosScr.elm.all.tags('a')
  for(var i=0;i<alllinks.length;i++) {
   var li = alllinks[i]
   if(li.name==name) {
    var coords = IbsMinimalScroll.getCoords(li)
    destX = coords.x - this.getPageX()
    destY = coords.y - this.getPageY()
   }
  }
 }
 else if(is.ns4) {
  var alllinks = this.doc.anchors
  for(var i=0;i<alllinks.length;i++) {
   var li = alllinks[i]
   if(li.name==name) {
    destX = li.x
    destY = li.y
   }
  }
 }

 // Apply offsets
 destX -= xoff
 destY -= yoff

 // Move layer within parent
 this.moveTo(ignoreX?this.x:-destX,ignoreY?this.y:-destY)
}


I'll make into a proper extension as soon as I can. In the meantime,
enjoy this.
