Adding Javascript "if-else" to this onClick

I have a js code like this:

 function test()
   {  alert("hello") ;  return true;}

***I have a button like this:
<asp:Button ID="btnLookupByPostalCode" runat="server" OnClick="btnLookupByPostalCode_Click"  />

  -- I want to add something like this :  onClick= "if return(test() == true) { btnLookupByPostalCode_Click; } "

can I do that?? I get errors...

You can only use return within a function. This is incorrect:
if return

try:
<asp:Button ID="btnLookupByPostalCode" runat="server" OnClientClick="if( test() ){btnLookupByPostalCode_Click();}"  />

that btnLookupByPostalCode_Click is ASP.Net's onClick event for the button. It's not a JS function so I get an error that object is required.

I dont think I can call a ASP.Net onClick event from JS. no?

This javascript will work:

<script type="text/javascript">
function test() {
return true;
}
function btnLookupByPostalCode_Click() {
alert("Testing");
}
</script>


<button onClick="if (test()) {btnLookupByPostalCode_Click();}">Click me</button>

As I said : btnLookupByPostalCode_Click is NOT a javascript function. It's C#'s onClick event for the button. That code is NOT a JS code. It's C# in code behind.
