Javascript error in range validation

[Lao Xu]

Hi, I'm new to Struts. It's convenient Struts provides validation for integer, required, etc. But I've problem with the range validation in Struts 1.1. Javascript error. Saying something about "intRange" error in javascript. Any help apreciated.

Hi,

It would probably help if you'd post the full error message and some relevant code snippets (the validation config file).

I just wonder why the Struts validation will lead to JavaScript errors. As if you have configured Struts well, when errors encountered after calling the method validate(), the original page will be shown.

Could you post the validate() method, as well as the validate.xml?

When I enter an invalid range and try to submit the form, the error uccur. The non-javascript error msg <html:errors/> shows the right error msg though.

The javascript error msg in IE:
'intRange' is undefined

The javascript error msg in Opera:
Event thread: onsubmit
Error:
name: ReferenceError
message: Statement on line 479: Reference to undefined variable: No such variable 'intRange'


I think it has something to do with the line "oRange = new intRange();" in validator-rules.xml


This is what I use in validation.xml

<form-validation>
<formset>
<form name="someForm">
<field property="someNumber" depends="required,integer,range">
<arg0 key="some.number"/>
<arg1 name="range" key="${var:min}" resource="false"/>
<arg2 name="range" key="${var:max}" resource="false"/>
<var>
<var-name>min</var-name>
<var-value>11</var-value>
</var>
<var>
<var-name>max</var-name>
<var-value>20</var-value>
</var>
</field>
</form>
</formset>
</form-validation>

what does your jsp look like? i don't think struts validation has anything to do with javascript...

The Struts Validator component can generate client-side validation functions in JavaScript as well as server-side validation methods.

Lao, try this in your validation.xml:

<field property="someNumber" depends="required, intRange">
    <arg0 key="some.number"/>
    <arg1 name="intRange" key="${var:min}" resource="false"/>
    <arg2 name="intRange" key="${var:max}" resource="false"/>
    <var>
        <var-name>min</var-name>
        <var-value>11</var-value>
    </var>
    <var>
        <var-name>max</var-name>
        <var-value>20</var-value>
    </var>
</field>

Okay, I've tried using

<field property="someNumber" depends="required, intRange">

But the error is still the same. Am I the only one experience this? Other validation, like "required, integer" don't have problem though.

[Lao Xu]

Sorry, I meant

<field property="someNumber" depends="required, range">

[Lasse Koskela]

Did you also try "intRange" as the argX name (instead of "range")?

[Lao Xu]

Nope, I tried "range"...

Not once have I seen client side javascript validation work.

I see problems currently and I am actually anchored to the struts april 2003.

What hope do I have of using client side javascript validation with the april 2003 struts 1.1 release ?

Can someone post a working sample ?

It does not work.

Can someone post something please that works.
