use event.off() method // here event is the object you have passed in the callback function
//of event

for example,

$( "p" ).off( "click" )

You can do this:

<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" OnClientClick="javascript:return AnsCheck()" />

javascript

 funcion AnsCheck(){
    //Based on code and condition you can return
    if(condition){
        return true // will fire server side event
    }
    else{
        return false; // will not fire server event
    }
  }

Or 

<asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" OnClientClick="javascript:return AnsCheck() return false;" />

return false is the answer, for onClientClick in function or in button attributes

asp:Button ID="Button1" runat="server" Text="Submit" OnClick="Button1_Click" OnClientClick="javascript:AnsCheck();return false;" />

You need to return false, in your javascript function, and in the OnClientClick specify a return call.

<script>
function AnsCheck()
{
    //do something 

    if (someCondition == true)
        return true;
    else
        return false;
}
</script>

<asp:Button ID="Button1" runat="server" Text="Submit" 
OnClick="Button1_Click" OnClientClick="javascript:return AnsCheck()" />
