姓氏名验证

Question

I have a textbox which allows users to enter their name and it should be like LastName,First Name format. The below JS works perfectly as expected. I will call this function on OnClientClick event in the button click. But I have n number of textbox that needs to be validated and now I would need to replicate this function for all the textboxed repeatedly. Is there any way to reconstruct this that can be used for all the textbox which will reduce the code quantity and pain in the neck.

 function onFirstNameLastName() {
        var name = /^\w{1,20}\, \w{1,20}$/ 
        var Id = document.getElementById("bodycontent_Updates");
        var flabels = document.getElementById('<%=((TextBox)Updates.FooterRow.FindControl("txtName")).ClientID %>');
        if (flabels != null) {
            if (flabels.value != "") {
                if (!name.test(flabels.value)) {
                    alert('Please enter Last Name, First Name format');
                    document.getElementById('<%=((TextBox)Updates.FooterRow.FindControl("txtName")).ClientID %>').focus();
                    return false;
                }
                else {
                    return true;
                }
            }
            else if (name.test(flabels.value)) {
                return true;
            }
            else if (flabels.value == "") {
                return true;
            }
        }
    }

The current regular expression I use will allow name like this Clark, Michael but I also need to allow names in this format too Tim Clark, Duncan Vince which my current regex doesn't support.

Really appreciate any suggestions.

If your all textboxes contains same data then first use ValidatorHookupControl http://msdn.microsoft.com/en-us/library/aa338815(v=vs.71).aspx to register your controls for validation and attach same JS function name which will validate data in it.

If you have different data in your textboxes then use custom validator and trigger the same on Submit click. In custom validator go through each text box and call required validation function.
