Problem with Java Script Validation

[springmedia]

Hi there guys, I have just inherited a new client who has a site developed with a javascript validation on the enquiry form.

I'm not too familiar with this and need to amend the the bold, eg emailz with an email reg expression.

and the phonez to only validate on numbers only.

This client is currently getting spammed heavily and we can't use captcha, just yet.

If there is anyone that can help I would be much appreciative.

Thanks again,

Rich.

function validate(){

var strFieldName, objFieldName;
var strNameValue, strPhoneValue, strEmailValue
var strNotesValue, strPostcode

strFieldName = "document.quickform.namez";
objFieldName = eval(strFieldName);
strNameValue = objFieldName.value;

if (strNameValue =="") {
alert("Please enter your name to send this enquiry.");
return false;
}

strFieldName = "document.quickform.emailz";
objFieldName = eval(strFieldName);
strEmailValue= objFieldName.value;

if (strEmailValue=="") {
alert("Please enter your email to send this enquiry.");
return false;
}

strFieldName = "document.quickform.phonez";
objFieldName = eval(strFieldName);
strPhoneValue= objFieldName.value;

if (strPhoneValue=="") {
alert("Please enter your contact phone number to send this enquiry.");
return false;
}

strFieldName = "document.quickform.detailsz";
objFieldName = eval(strFieldName);
strNotesValue= objFieldName.value;

if (strNotesValue=="") {
alert("Please tell us some details of your accident to send this enquiry.");
return false;
}

strFieldName = "document.quickform.postcodez";
objFieldName = eval(strFieldName);
strPostcode= objFieldName.value;

if (strPostcode=="") {
alert("Please enter your postcode to send this enquiry.");
return false;
}
else {
if (checkPostCode (strPostcode)) {
var iCheck = 1;
}
else {
alert ("Postcode has invalid format");
return false;
}
}
}
