Question

I’m new on Dojo, and I’m trying to validate a form (like the last one of this example : http://dojotoolkit.org/documentation/tutorials/1.6/validation/), using Struts2 tags, but I can’t.
With a “classic” HTML form (tags , ….) everything is fine, but with Struts 2 tags (), the “required” validation don’t work …

Here is my code :

    <script type="text/javascript">
        dojo.require('dojox.validate');
        dojo.require('dojox.validate.us');
        dojo.require('dojox.validate.web');

        /* basic dijit classes */
        dojo.require('dijit.form.CheckBox');
        dojo.require('dijit.form.Textarea');
        dojo.require('dijit.form.FilteringSelect');
        dojo.require('dijit.form.TextBox');
        dojo.require('dijit.form.ValidationTextBox');
        dojo.require('dijit.form.DateTextBox');
        dojo.require('dijit.form.TimeTextBox');
        dojo.require('dijit.form.Button');
        dojo.require('dijit.form.RadioButton');
        dojo.require('dijit.form.Form');
        dojo.require('dijit.form.DateTextBox');

        /* basic dojox classes */
        dojo.require('dojox.form.BusyButton');
        dojo.require('dojox.form.CheckedMultiSelect');
    </script>

<s:form dojoType="dijit.form.Form" method="post" id="toto" 
 theme="simple">
      <script type="dojo/method" event="onSubmit">
            if(this.validate()) {
               return confirm('Form is valid, press OK to submit');
            } else {
               alert('Formulaire invalide');
             return false;
            }
return true;
            </script>
            <table cellpadding="0" cellspacing="2">
                <tr>
                    <td valign="top"><strong>First Name*: </strong></td>
                    <td>
                        <s:textfield
                            name="email"
                            id="email"
                            placeholder="Your email" 
                            dojoType="dijit.form.ValidationTextBox" 
                            required="true"
                            missingMessage="Obligatoire !" />
                    </td>
                </tr>
            </table>

                <s:submit
                    value="Submit Form" 
                    label="Submit Form"
                    id="submitButton" 
                    dojoType="dijit.form.Button"/>
            </s:form> 

How can I check that my fields are not empty with struts tags please ?
Thank you all

You need to check to make sure that what you’re rendering is what Dojo expects. I don’t know how the current Dojo validation works, but:

The “required” attribute is an attribute of <s:textfield>, it’s likely not being rendered, thus not available to Dojo–if that’s what Dojo uses to determine if a field is required.
