test.jsp:
%%%%%%%%%%%%%
< s:property value="#parameters.type"/>
< s:if test="#parameters.type == 1">
< select>
< option value="-1">
请选择
< /option>
< option value="1" selected>
收件箱
< /option>
< option value="2">
发件箱
< /option>
< /select>
< /s:if>
%%%%%%%%%%%%%%
when this page is accessed by test.jsp?type=1
the s:if test is false, so the select list is not showed.
Can somebody tell me why? thanks!
I hope you understand that your code is not good struts2 practice. That's not the way Struts2 is supposed to be used normally. Your http parameters should normally be mapped to your action fields, and (after your action has done its work) your jsp should show the results pulling them from the same action. Normally. And normally, you should not need to access http parameters in your jsp, nor do any logic (except for very trivial ones).
Anyway, perhaps the problem in your test is that #parameters.type is a raw string, and you are comparing it to a number. (That's one of the many problems of violating the normal Struts2 flow - the convertion from plain strings to more meaningful types is normally done in that mapping, by the param interceptor. The problem would not arise is you had a proper integer 'type' field in your action, and in your jsp you ask for it) Did you try #parameters.type == '1' ?
I've solved the problem. just substitute the "#parameters.type" with "#parameters.type[0]".
Then the test works!
Thats because struts2 treat the parameters form URL as an array.

Say I have the following q-input:
<q-input
v-model="form.email"
inverted-light
color="white"
stack-label="Email:"
type="email"
#blur="$v.form.email.$touch"
:error="$v.form.email.$error"/>
I'd like to be able to make it so that if the domain of the email is mydomain.com that the form action will change to another website (without csrf protection) and the POST will be made to that website instead of the main one.
To do this I was thinking I could use jQuery. eg. $('#email').val().replace(/^.+#/, '') == 'mydomain.com' then change the form action and submit.
The only problem is: I don't know how to set an id attribute on q-input.
Any ideas?
As of early Quasar 1.4.2 (November of this year) you can specify the id value on the resulting html generated by q-input by using the "for" property (see the end of the behavior properties: https://quasar.dev/vue-components/input#QInput-API).
So, for example, you could add for="myInputId":
<q-input
v-model="form.email"
inverted-light
color="white"
stack-label="Email:"
type="email"
#blur="$v.form.email.$touch"
:error="$v.form.email.$error"
for="myInputId"
/>
The id attribute with value "myInputField" will end up on the resulting <input> element in your HTML.
Not using the "for" in the elements gave me a lot of headaches because the Jest snapshot generated random IDs
I am using struts-2.3.16.3 for my application. My action implements the “ModelDriven” interface. Using interceptor reference as defaultStack.
The problem that i am facing is, all the special characters (non keyboard characters like ®, ℗) are disappearing from my model property by the time they reach to my action class. Other special characters like # # $ etc able to see those in my action.
Do i need to configure any other interceptors in the stack?. Help needed if i am missing in configuration.
Example: If i enter Piracy℗symbol in my text field, in action class when i print property value it shows Piracysymbol.
Thanks,

I think the problem is that you have not mentioned the content-type. Try putting
<%# page contentType=”text/html;charset=UTF-8″ %> tag in your code if you haven't already. If the problem still persists write your code like this
<s:text name="username"/> <s:property value="getText('username')"/>
Hope this helps.
I have an (as yet) simple Spring 3 MVC web-app using JSP as the view technology. I am considering rewriting it in Grails before I get too far along.
One thing I like about Spring is the "form" tags provided in the spring-form.tld tag-library. Given a model property "myFormModel" with the "myProperty" property, this allows me to write something like: -
<form:form commandName="myFormModel">
<form:input path="myProperty" cssErrorClass="error"/>
The key here is that the form:input tag automatically does all the binding to the property in the command object, so generating (roughly) in HTML: -
<form>
<input type="text" name="myProperty" value="xyz"/>
Spring MVC will bind the form parameters to the class and pass the object to the controller. Less to go wrong.
(Please excuse the JSP and HTML, it's indicative, possibly slightly incorrect)
As I understand the GSP form tags: -
<g:form name="myForm" url="[controller:'myController', action:'foo']">
<g:textField value="${myFormModel.myProperty}" class="${...blah to select error}"/>
I cannot specify a "path" attribute: I must manually generate the name. When the path becomes complex (say a property of a item from a list), this can become hairy and noisy.
I cannot automatically specify both "normal" and "error" CSS classes: I must put EL into the <input> class attribute. Messy!
I must admit I am surprised that GSP is (what I consider) behind Spring, I thought it was all about making the obvious things simple and the hard things possible. Easy-to-read/implement forms would seem a no-brainer.
So, my questions: -
am I missing something?
should I (and can I) use the spring-form.tld in my GSP?
It makes me wonder what other gotcha's I will run into...
The beanFields plugin does everything the Spring form tags do and more. It makes working with forms about as concise as possible.
Im very new to grails (1.3.7) so please be patient :-)
I have a gsp where I have various checkboxes. A user can click on them and then send his answer to a controller. The controller is receiving this request correctly.
My problem is, that, for working with what the user chose, I have to check every parameter - to see if this checkbox was really checked. Thats really cumbersome and doesnt work very well, because the page displaying the checkboxes is dynamic - so the checkboxes which can be clicked are dynamic too. In my controller I dont know for which params I have to check then.
Is there any possibility to receive a list of all checkboxes (or better: all checked checkboxes) in my controller? I researched but didnt find an answer!
Thanks for answering! :-)
[EDIT]
Thank you,
params.name.each{i->
System.out.println(i);
}
is very simple and works :-) It just gives back the checked ones
It must be passed as an extra request parameter (it's a limitation of http). You can add following field into your form, for example:
<input type="hidden" name="checkboxes" value="${myCheckboxesNames.join(',')}"/>
or making same using JavaScript, as it names are dynamic on client side.
BTW, you can also check all request parameters, by
params.each { name, value ->
// so something
}
so if you are using some special prefix/suffix for this checkbox names, it would be:
params.entrySet().findAll {
it.key.startsWith(prefix)
}.each {
println "Checkbox $it.key = $it.value"
}
I'm still new to grails and i kind of stuck in a problem where i can't use the Jsp tags that i put in the /WEB-INF/tags
if i create a tag file called text.tag and put in it the normal HTML input text tag
and i go to the GSP and make the taglib
< %# taglib prefix="myTags" tagdir="/WEB-INF/tags"%>
then trying to call it by
< myTags:text/>
it gives me nothing.. in fact if i checked the html source i find < mytags:text/>
is there special way for that cause i need that in more sophisticated tags.
I would recommend writing the tags as grails tags
http://grails.org/Dynamic%20Tag%20Libraries
those tags are easier to write, but the answer to your original question is also documented at the link above
