I'm in the middle of a problem, which I hope someone can throw an idea at me. The fact is that I have to open a popup window, which I must call it from the box that opens infowindow. Below I show you the code with which I can open a page, but in my case it does not work, what I must open is a popup. I have tried several ways, but I am already at a point where I think the tree does not let me see the forest.
var contentString = '<div id="div_cliente">'+
'<b>'+cliente+'</b><br/>' +
rubro+'<br/>' +
'<b>'+titular+'</b><br/>' +
RUC+'<br/>' +
'<b>'+tele+'</b><br/>' +
tari+'<br/>' +
'<b>'+deuda+'</b><br/>' +
'<p>Prueba llamada, <a href="prueba_ventana.php?valor=111111">'+'Click aqui</a>' + '</p>'+
'</div>';
This works, but as I said before, what I need is to open a popup, not open a new page.
Thank you in advance.
