[ka-Map-users] Re: Kamap Query System

[Peter Giencke]

Paul,

There is, just added a bit of code to kaTool.js for this to work. 

////code starts here
function kaNavigator_onmousedown(e)
{

    e = (e)?e:((event)?event:null);
 
        //added code
        if(queryThis == 1) //button in application toggle between query mode
and browse mode, queryThis = 1 is in query mode
        {
        var aPixPos = this.adjustPixPosition( e.clientX, e.clientY );
	  var geoCoo= this.kaMap.pixToGeo(aPixPos[0],aPixPos[1]);
	  this.gX = geoCoo[0];
    	  this.gY = geoCoo[1];
	  this.gX= (parseInt(this.gX*100))/100;
    	  this.gY= (parseInt(this.gY*100))/100;
        var vLayers = getVisibleLayer();
        var extent = this.kaMap.getGeoExtents();
        this.cursor = 'help';
        var
params='x='+this.gX+'&y='+this.gY+'&layer='+vLayers+'&extent='+extent[0]+'|'
+extent[1]+'|'+extent[2]+'|'+extent[3];
        toSendLink = "showResults.php?" + params;
        return this.cancelEvent(e); //as to not pan when querying
        }
        //end

    if (e.button==2)
    {
        return this.cancelEvent(e);
    }
    else
    {
        if (isIE4) document.onkeydown = kaTool_redirect_onkeypress;
        document.onkeypress = kaTool_redirect_onkeypress;
        
        this.bMouseDown=true;
        this.lastx=e.clientX;
        this.lasty=e.clientY;
        
        e.cancelBubble = true;
        e.returnValue = false;


        
        if (e.stopPropogation) e.stopPropogation();
        if (e.preventDefault) e.preventDefault();
        return false;
    }  
} 

function getVisibleLayer(){
//function courtesy of Lorenzo/rischio

 var    inputList =  document.getElementsByTagName('input');
 var a=new Array();
 var layerList="";
 var n=0;
 for(i=0;i<inputList.length;i++){
    if(inputList.item(i).name=='layerVisCB' && inputList.item(i).checked)
    { 
    a[n] = inputList.item(i).value;
    n++;  
    }
 }
  
  
  for(i=0;i<a.length;i++){ 
  
  if(i==0)
  layerList=a[i];
  else 
  layerList = layerList+","+a[i];
}
 return layerList;
}
/////end
