Highlight Multiple Input ID's on javascript validation

using javascript validation and some jquery to show variable error messages in the DOM, and highlighting b开发者_运维知识库oth the form label and field.

For this particular error message, I need to highlight 2 fields (email1 and email2). Unsure how to add it to my current setup for alerts below:

customAlert ("email2",bnadd_msg_022);

simple question, how to I add email1 into the mix?

Edit:

Here is my jquery function:

function customAlert(inputID,msg){

      $("li").removeClass("alertRed");
      $("input").removeClass("CO_form_alert");  
      $("select").removeClass("CO_form_alert");   
      var div = $(".errorPopup");
      div.css({"display":"block"});
      $("#"+inputID).addClass("CO_form_alert").parent().addClass("alertRed");
      if (div.length == 0) {
        div = $("<div class='errorPopup' onclick='$(this).hide();'></div>");
        $("body").prepend(div);
      } 
      div.html(msg);
      $("#"+inputID).focus(function(){
        $(this).unbind('focus'); // remove this handler
        $('.errorPopup').hide(); // hide error popup
   });

So, In this case and on one other, I need to highlight 2 fields simultaneously

I'd make use of the arguments 'array' in Javascript, and simply define customAlert as a function with no arguments.

function customAlert(){
    var args = arguments;
    if(args.length > 1) {
        // check that custom alert was called with at least two arguments
        var msg = args[0];
        $("li").removeClass("alertRed");
        $("input").removeClass("CO_form_alert");  
        $("select").removeClass("CO_form_alert");   
        var div = $(".errorPopup");
        div.css({"display":"block"});
        if (div.length == 0) {
            div = $("<div class='errorPopup' onclick='$(this).hide();'></div>");
            $("body").prepend(div);
        } 
        div.html(msg);
        for(var i = 1; i < args.length; i++) {
            var inputID = args[i];
           $("#"+inputID).addClass("CO_form_alert").parent().addClass("alertRed");
            $("#"+inputID).focus(function(){
                $(this).unbind('focus'); // remove this handler
                $('.errorPopup').hide(); // hide error popup
            });
        }
     }
}

Then you call it like so:

customAlert(bnadd_msg_022,"email2"); // note the order of the arguments has changed
customAlert(bnadd_msg_022,"email1","email2");

Without seeing the code, my guess is that you could change the customAlert function to take an optional third argument.

The way I would do it is make that third argument an array that can accept n number of field id's. In the customAlert function, I would check to see if the argument is passed, and if so loop through the array and highlight any id that is included therein.
