RE: Struts Validator 1.1 -- Solution WIll Not WOrk
The solution given below does not work for the case I described. jsType.jsp
defines one form with several masked field validations.
The example I'm having difficulty with is multiple forms with multiple
fields with masked field validation which causes the Struts Validator to
generate multiple versions of the function
function mask () {}
for each of the validator:javascript entries shown below:
(1) validator:javascript formName=form1
dynamicJavascript=true staticJavascript=false/
(2) validator:javascript formName=form2
dynamicJavascript=true staticJavascript=false/
The first validator tag generates the following code (note the function
mask() )
SCRIPT LANGUAGE=Javascript1.1
!-- Begin
var bCancel = false;
function validateForm1(form) {
if (bCancel)
return true;
else
return validateMask(form);
}
function mask () {
this.aa = new Array(field6, Field 6 is
invalid., new Function (varName, this.mask=/^\\d{7}/; return
this[varName];));
}
// End --
/SCRIPT
while the second validator tag generates the following code (note the
additional function mask() : NAMING CONFLICT )
SCRIPT LANGUAGE=Javascript1.1
!-- Begin
var bCancel = false;
function validateOmpModel(form) {
if (bCancel)
return true;
else
return validateRequired(form)
validateMask(form) validateMaxLength(form) validateMinLength(form)
validateInteger(form) validateRange(form);
}
function mask () {
this.aa = new Array(field1, Field 1 is invalid.,
new Function (varName, this.mask=/^\\d{6}/; return this[varName];));
this.ab = new Array(field2, Field 2 is invalid.,
new Function (varName, this.mask=/^[ALST]/; this.maxlength='1'; return
this[varName];));
this.ac = new Array(field3, Field 3 is
invalid., new Function (varName, this.mask=/^\\d{6}/;
this.maxlength='6'; return this[varName];));
this.ad = new Array(field4, Field 4 is invalid.,
new Function (varName, this.mask=/^\\d{1}/; return this[varName];));
this.ae = new Array(field5, Field 5 is
invalid., new Function (varName, this.mask=/^\\c{1}/; return
this[varName];));
}
// End --

the problem lies in the last statement shown in the code listing below which
is defined in validator-rules.xml and generated by the static JavaScript
validator name=mask
classname=org.apache.struts.validator.util.StrutsValidator
method=validateMask
depends=required
msg=errors.invalid
javascript![CDATA[
function validateMask(form) {
var bValid = true;
var focusField = null;
var i = 0;
var fields = new Array();
oMasked = new mask();
When the function runs the line oMasked = new mask();, it always retrieves
the second mask() and thereby errs when attempting to validate the first
form since (in the example I gave above), there is no field by the name of
field6 in the second function mask() instance ( I get a JavaScript error on
the following line form[oMasked[x][0]].value since form[oMasked[x][0]] is
undefined ).
I hope I have been clearer about the problem now.
The solution I had in mind was to modify the Struts Validator to generate
custom validation functions. So, for the example I gave above, it would
generate the following functions:
function maskForm1()
{
}
function maskForm2()
{
}

Sorry, there isn't a way to change this now. You
could file it in bugzilla as a feature request.
