switch(n)
{
case 1:
execute code block 1
break;
case 2:
execute code block 2
break;
default:
code to be executed if n is different from case 1 and 2
}

You don't have a lot of detail in your question but I'll try to help regardless - but without knowing the full scenario its a bit hard to give you a definitive answer.
I'm going to assume you want to handle a redirection on a button click, but with some conditions?
Usually you would use a simple case statement to handle this (or an if/else if there is only two conditions), such as the following (using jQuery for event bindings):
<button id="button1">Button 1</button>
<button id="button2">Button 2</button>
<script type="text/javascript">
jQuery(function() {
jQuery("button1, button2").click(function(e) {
switch(jQuery(this).attr("id")) {
case "button1":
location.href = "http://clickedonbutton1.com";
break;
case "button2":
location.href = "http://clickedonbutton2.com";
break;
default:
alert("Dont know what happened here....");
}
});
});
</script>

Read switch
No restriction on
case valuetype.You can use "string" case value in JavaScript
You can add duplicate case value. The first matching case value is recognized, regardless of duplicates.

It's not the same. You can't use strings in switch statements in C++.
