I think the class "org.apache.struts2.validators.DWRValidator" will not works so I try another way. I found a solution, maybe we can use it?
I found a good example using dwr here: https://www.jitendrazaa.com/blog/java/jsp/step-by-step-dwr-application-simple-ajax-in-java/ What is to do: - for using client validation we need the theme "xhtml" or "css_xhtml" (not "simple") - and the form has to us validation, example "<s:form action="test" validate="true" theme="css_xhtml" >" - we need drw-1.1.1.jar and struts2-dwr-plugin-2.5.26.jar (that's standard) - I create a new class "IdnToAscii" with the method "getIdnToAscii" (I propose to use the class "org.apache.struts2.validators.DWRValidator" for this) import java.net.IDN; public class IdnToAscii { public IdnToAscii() {} public String getIdnToAscii(String psUrl) { if (psUrl == null) { psUrl = ""; } return IDN.toASCII(psUrl); } } - create or change in the WEB-INF-folder the file dwr.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE dwr PUBLIC "-//GetAhead Limited//DTD Direct Web Remoting 1.0//EN" "http://www.getahead.ltd.uk/dwr/dwr10.dtd";> <dwr> <allow> <create creator="new" javascript="validator"> <param name="class" value="org.apache.struts2.validators.DWRValidator"/> </create> <create creator="new" javascript="IdnToAscii"> <param name="class" value="de.guenterpaul.ajax.dwr.IdnToAscii"/> </create> <convert converter="bean" match="com.opensymphony.xwork2.ValidationAwareSupport"/> </allow> <signatures> <![CDATA[ import java.util.Map; import org.apache.struts2.validators.DWRValidator; DWRValidator.doPost(String, String, Map<String, String>); ]]> </signatures> </dwr> - I use the "css_xhtml" theme - I change the file "resources/template/css_xhtml/form-validate.ftl" <#if parameters.validate!false == true> <script type='text/javascript' src='${base}/dwr/interface/IdnToAscii.js'></script> <script type='text/javascript' src='${base}/dwr/engine.js'></script> <script type="text/javascript" src="${base}/struts/css_xhtml/validation.js"></script> <script type="text/javascript" src="${base}/struts/utils.js"></script> <#if parameters.onsubmit??> ${tag.addParameter('onsubmit', "${parameters.onsubmit}; return validateForm_${parameters.id?replace('[^a-zA-Z0-9_]', '_', 'r')}();")} <#else> ${tag.addParameter('onsubmit', "return validateForm_${parameters.id?replace('[^a-zA-Z0-9_]', '_', 'r')}();")} </#if> </#if> - I copy the file "resources/template/xhtml/form-close-validate.ftl" int the "css_xhtml" folder and change the url-validator: <#elseif validator.validatorType = "url"> if (continueValidation && fieldValue !== null && fieldValue.length > 0) { DWREngine.setAsync(false); IdnToAscii.getIdnToAscii(fieldValue, function(idnurl) { fieldValue = idnurl; }); alert("URL >" + fieldValue + "<"); if (continueValidation && fieldValue !== null && fieldValue.length > 0 && fieldValue.match(/${validator.urlRegex}/i) === null) { addError(field, error); errors = true; <#if validator.shortCircuit>continueValidation = false;</#if> } } That's all. It's important to use DWR in sync-mode. We only convert the field-value to IDN (using JAVA at the server) and after we check the changed value. We can use the same way by email-validation. And xhtml-theme is the same way, I think (I can't use it in my project, so I don't test it here). Hope it's useful. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
