Firstly I should point out that naming a field (and a submit button qualifies in this category) on your form "action" is a very bad idea (as it shadows the action property of the form object in the client side object model - so if you ever need to play with a forms action path in javascript on the client side you will find you cant get at it! (you should in general avoid naming your form properties the same as anything thats a (js) form object method or property. "submit" is another fun one - you should never name your submit button "submit"! hehe)... ) (It doesnt help that half the struts examples make this egregious mistake!)
Ok. Now getting on to your question. I the html:form tag does not have a 'value' attribute. What you need is to use an html:submit tag to render your submit button. ie: <html:submit property="action" value="confirm"/>. The submit tag (which just renders the html <input name="action" type="submit" value="confirm"/>) takes a 'value' attribute. This is what will be submitted in the 'action' request parameter. It is however _also_ what gets displayed as the label on the button! (If you are using i18n you will want to go take a look at the javadocs for LookupDispatchAction at this point). The easiest way round this label_is_value issue is to make 'action' a hidden field and the button they click sets it in javascript and submits the form - however that only works if javascript is enabled. And I'll mention it one last time: DONT CALL THE PARAMETER "action" !!!! Thats bad. Call it "doAction" or "method" or "bob" but naming it the same as properties of the js form object (ie: action, submit, elements, etc...) is not a great idea.... -----Original Message----- From: yan [mailto:[EMAIL PROTECTED] Sent: Tuesday, 2 September 2003 23:28 To: [EMAIL PROTECTED] Subject: help: request.getParameter("action") I am using a single jsp (registration.jsp) that can be used in one of three different ways: 1. create a new registration, user clicks on hyperlink <html:link page="/editRegistration.do?action=create"> 2. edit existing registration details, user clicks on hyperlink <html:link page="/editRegistration.do?action=edit"> 3. user confirms a new registation or confirms update existing details (i.e registration.jsp is used to display to the user the fields they are about to commit to the database) in this case, the user will click on a BUTTON, not a hyperlink: <html:form "action="/editRegistration.do" value="confirm"> In my EditRegistrationAction class, I want to check the the value of the 'action' attribute: String action = request.getParameter("action") My problem is that I am not sure if the value="confirm" attribute/value pair on the button will be detected by the request.getParameter("action") method. Will I therefore need a separate variable to check for the button i.e. String value = request.getParameter("value") many thanks yan Kickstart e Solutions. - Intelligent Web Services [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
