Making Contact Standard Fields Mandatory

To make contact standard fields mandatory, you must create a custom field of type Custom Field Type: Special – Browser Script and place it on the same entity that you'll be using it. For contacts, you'll want to put the custom field in via Global Settings > User & Contact Settings > Contact Custom Fields

function savefunc(frm){
   var element=frm.uaddress;
   if(element&&element.value.length==0){
      alert("Address is empty!");
      return false;
   }
   element=frm.phone;
   if(element&&element.value.length==0){
      alert("Phone is empty!");
      return false;
   }
   element=frm.ucity;
   if(element&&element.value.length==0){
      alert("City is empty!");
      return false;
   }
   element=frm.ucountry;
   if(element&&(element.value.length==0||element.value=="0")){
      alert("Country is empty!");
      return false;
   }
   element=frm.email;
   if(element&&element.value.length==0){
      alert("Email is empty!");
      return false;
   }
   return true;
}
