  1. Hello there! Please kindly note that I've been staring down this code for days now, and I can't seem to get why the regular expression test method doesn't work (and why Firebug says "it is not a function" when my code skips over everything that deals with the results of the test method). I am trying to create a utility function for form validation that passes in an id and a regular expression. Here is my calling code: regularExpressionMatchFunction("firstName", "/^[A-Za-z'\.]+\s*[A-Za-z'\.\s]*$/"); Here is the code with the erroneous component in bold: function regularExpressionMatchFunction(id, regularExpressionMatch) { //declare variables used in field check. alert("At beginning of function, the regular expression is " + regularExpressionMatch); var fieldName; var fieldNameValue var regExFieldName var finalRegExpressBooleanFieldName var fieldNameValueTrimmed // Get field name and field value fieldName = document.getElementById(id); fieldNameValue = fieldName.value; // TRIM WHITE SPACE Function Called here-- prepare code for trimming off white space on fieldName value fieldNameValueTrimmed = trimWhiteSpace(fieldNameValue); alert("My fieldNameValueTrimmed is" + fieldNameValueTrimmed); // Now for the regular expression, which looks for letters, apostrophes, and periods, although I don't need to escape the period (plus white space // Have to change the fieldNameValue to trimmed version above // HERE IS ERROR HERE IS ERROR HERE IS ERROR // NOT RECOGNIZED AS A FUNCTION finalRegExpressBooleanFieldName = regularExpressionMatch.test(fieldNameValueTrimmed); // EVERYTHING AFTER THE ABOVE CODE JUST GETS SKIPPED OVER, INCLUDING THE FOLLOWING ALERT MESSAGE alert("After doing regular expression MATCH, the value of finalRegExpressBooleanFieldName (the boolean) is " + finalRegExpressBooleanFieldName); // These alerts need to be replaced with calls to addErrorMessage and removeErrorMessage if (finalRegExpressBooleanFieldName == true) { //removeErrorMessage inserted here will take the element by id field but not an error message as arguments removeErrorMessage(id); alert("You are an awesome coder!"); } else { // addErrorMessage will take the getElementById field "firstName" and also the error message as arguments addErrorMessage(id, "The name value must include alphabetical letters (and can include apostrophes, periods, and spaces)"); alert("You code like toodles"); // The return false code didn't work in the addErrorMessage function itself, so I'll try it here return false; } } If anyone can help me figure out why the code breaks at the test method in bold above, I would be most appreciative! Thank you so very much!
