Hi,Yves G:
Thanks for your help, now the content of popup is displayed normally,and a
new problem is appeared, I just add extra infomation in coodCollection
array, depend this infomation, the marker could change the icon accordingly,
and now I get all the icon name as this: "img/mini_circle.png", the color
parameter is right.
//*******************************************
markers = new OpenLayers.Layer.Markers("Markers2");
map.addLayer(markers);
var size = new OpenLayers.Size(21, 25);
var offset = new OpenLayers.Pixel(-(size.w / 2), -size.h);
//
for ( var i = 0; i < (coodCollection1.length / 3); i++) {
var lon = coodCollection1[i * 3];
var lat = coodCollection1[i * 3 + 1];
var color = coodCollection1[i * 3 + 2];
var size = new OpenLayers.Size(21, 25);
var offset = new OpenLayers.Pixel(-(size.w / 2),
-size.h);
var iconName;
// color:0 red,1 blue,2 gold,3 green
alert("color is "+color);
switch (color) {
case 0:
iconName = 'img/marker.png';
break;
case 1:
iconName = 'img/marker-blue.png';
break;
case 2:
iconName = 'img/marker-gold.png';
break;
case 3:
iconName = 'img/marker-green.png';
break;
default:
iconName = 'img/mini_circle.png';
}
var icon = new OpenLayers.Icon(iconName, size, offset);
marker = new OpenLayers.Marker(new
OpenLayers.LonLat(lon, lat),
icon.clone());
alert("1color is "+color);
marker.events.register("mouseover", marker,
popupHandler(marker,
coodCollection1, i));//
marker.events.register('mouseout', marker,
function(evt) {
popup.hide();
});
markers.addMarker(marker);
//********************************************
It looks should be the closures issue too, andI try several function factory
way, it's not work.
one of my code is as below:
//---------------------------------
function makeName(coodCollection,x) {
return function() {
switch (coodCollection[x * 3 + 2]) {
case 0:
iconName = 'img/marker.png';
break;
case 1:
iconName = 'img/marker-blue.png';
break;
case 2:
iconName = 'img/marker-gold.png';
break;
case 3:
iconName = 'img/marker-green.png';
break;
default:
iconName = 'img/mini_circle.png';
}
return iconName;
};
}
var iconName = makeName(coodCollection,i);
//---------------------------------
but it returned the text file of the function, how about your idea?
