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 -->
</SCRIPT>
In the static JavaScript generated by the following tag
<script language="JavaScript1.1"
src="../includes/staticStrutsValidatorJavascript.jsp"></script>
staticStrutsValidatorJavascript.jsp
------------------------------------
<%@ page language="java" %>
<%-- set document type to Javascript (addresses a bug in
Netscape according to a web resource --%>
<%@ page contentType="application/x-javascript" %>
<%@ taglib uri="/WEB-INF/struts-validator.tld"
prefix="validator" %>
<validator:javascript dynamicJavascript="false"
staticJavascript="true"/>
-------------------------------------
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()
{
....
}
and the validateMask() function in validator-rules.xml would need to be
modified to generate the following:
<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();
functionName = 'oMasked = new mask' + form.name +
'()';
eval(functionName);
....
Is there any other solution without my having to modify validator code to
generate the functions as shown above?

Subject: Re: Struts Validator 1.1
Creating a Separate Page for Static JavaScript
If you want to just generate the dynamic JavaScript on
you form page and have a separate page with the static
JavaScript to take advantage of browser caching you
can use the dynamicJavascript and staticJavascript
attributes to the JavascriptValidatorTag. You can turn
each attribute's generation of JavaScript on and off
by putting in true or false (they default to true).
Reference jsType.jsp and staticJavascript.jsp in the
main example webapp for a working example.
In your form page:
<validator:javascript formName="typeForm"
dynamicJavascript="true" staticJavascript="false"/>
<script language="Javascript1.1"
src="staticJavascript.jsp"></script>
This wouldn't work right in IE 5.0 when I made the
source an attribute of the tag.
In your static JavaScript page.
<%@ page contentType="application/x-javascript" %>
<validator:javascript dynamicJavascript="false"
staticJavascript="true"/>
http://home.earthlink.net/~dwinterfeldt/jsptags.html
There is an example of this in the example webapp.
