How do I load different pages in doGet with HTML Service programmatically? If it is impossible, why GAS editor allows creating different HTML pages?

If your loading different pages based on parameters passed in the URL you can test for the parameter using

function doGet(e) {
   if (e.parameter.messageID) {   // Simply test if the parm messageID exists

You can always do something like this too 

switch (v) {
   case "A":   var t = HtmlService.createTemplateFromFile("A");  break;
   case "B":   var t = HtmlService.createTemplateFromFile("B");  break;
}
return t.evaluate();

And my final option is you can put conditional logic into the template to get different HTML

 // GAS file
 var t = HtmlService.createTemplateFromFile("A");
 var v = "A";   
 t.v = v;  // pass the variable v to the template 
 return t.evaluate();

 // A.html template file
 <? if (v == "A") { ?>
    <b>a bold A</b>
 <? } else { ?>
    <b>not a A but bold anyway </b>
 <? } ?>

    Thank you. So if I load index.html at first, then how do I reload the doGet in order to reevaluate the condition you have above? – Andy Leung Oct 03 '12 at 12:40
