You can also use JSTL Notation.
<bean:define id="myVar" name="form" property="field"/>
<html:link action="" name="deleteDataParams" scope="page" validateDelete('${myVar}')"

Unfortunately it's not so easy, because you can't use a tag as an
attribute to the tag.
<html:link action="" name="deleteDataParams" scope="page"
validateDelete(<bean:write name="data"/>)"
This can't work, because the attribute (onclick) will not be evaluated.
There could be two possible solutions. First, leave the html taglib and
drop back to normal <a href...
Second: store the variable value in a _javascript_ variable:
<script>
var myData = '<bean:write name="data"/>';
</script>
<html:link action="" name="deleteDataParams" scope="page"
validateDelete(myData)"
Of course this only works if you have the value of myData at page
generating time. If the value is changed by something the user does on
page, like checking a checkbox, i would store it in a hidden field in
the form and read per _javascript_ in validateDelete(), like this:
for (var i=0;i < document.formname.elements.length;i++){
var e = document.formname.elements[i];
if (e.value == 'set' && e.checked==true){
doSubmit=true;
myData = e.value;
}
}
the above _javascript_ is only an example how to iterate over form fields
with _javascript_, it has not the required functionality.
