I have a jsp page with the tags:
<logic:iterate id="var" ...
....
<bean:write name="var" property="p1" ...
etc.
And I need, on each iteration, to generate a href composed from the various bean's properties. I even need to URLEncode some of them so the link works.
Something like
<logic:iterate id="var" ...
....
<html:link action="otheraction.do?_X_
<bean:write name="var" property="p1" ...
etc
where X is generated by collecting the bean's properties; something like
String X="p1="+URLEncode(p1)+"&p2="+SimpleDateFormatof(p2)+"&p3="+p3;
How can I do that ?
Thanks in advance.
Better to make one POJO class.
1. Assign all your values to the object in Action which is being called before your jsp page comes in the picture.
2. Keep the object of POJO to request attribute.
3. Get the value from request attribtue on JSP using <bean:write> tag.

I am writing a custom TagHelper that should change its behavior based on what child elements its owner tag has. This will be used for substituting custom html elements in a localized string.
Here's a simple example of what I'm trying to do:
<h2 locale-key="Hello, %1!">
<span class="bold" locale-parameter="1">#userName</span>
</h2>
In the example above, the TagHelper for LocaleKey will change the content of the <h2> tag to a localized string. If this is a simple string with no parameters, then I can just simply use output.Content.SetHtmlContent() in the TagHelper to set the h2's content to the string. However in this case, the localized string has a parameter (%1), and I want the corresponding child element (<span parameter="1">) to be substituted in the final output. So the final rendered html would look like this:
<h2>Hello, <span class="bold">Lázár Zsolt</span>!<h2/>
To achieve this, I should be able to see all the child elements in the DOM from the LocaleKey TagHelper, so I can generate the correct HTML code. In the TagHelper's ProcessAsync method I can access the TagHelperContext and the TagHelperOutput, but I couldn't find any information about child elements in either of these objects while debugging. Is this possible somehow?
Another approach is to leave the string as is, with the %1 parameter key, and then use the child ParameterTagHelper to substitute itself into the parameterized string. To do this, I'd have to see the siblings of the current tag from the TagHelper.
Recursion would also be fun (e.g. the <span> is also localized and has its own parameters), but for the scope of this question, I'd be happy if I could get this to work without recursion.
I posted too soon again... There is a GetChildContentAsync() method in TagHelperOutput that will... get the child content asynchronously.
I'm looking for a way to receive a XML Element (the id of an entry) from a YouTube feed (e.g. http://gdata.youtube.com/feeds/api/users/USERNAME/uploads).
The feed looks like this:
<feed xmlns="http://www.w3.org/2005/Atom" xmlns:media="http://search.yahoo.com/mrss/" xmlns:openSearch="http://a9.com/-/spec/opensearch/1.1/" xmlns:gd="http://schemas.google.com/g/2005" xmlns:yt="http://gdata.youtube.com/schemas/2007" gd:etag="W/"DUcFQncyfCp7I2A9WhVUFE4."">
<id>tag:youtube.com,2008:user:USERNAME:uploads</id>
<updated>2012-05-19T14:16:53.994Z</updated>
...
<entry gd:etag="W/"DE8NSX47eCp7I2A9WhVUFE4."">
<id>tag:youtube.com,2008:video:MfPpj7f6Jj0</id>
<published>2012-05-18T13:30:38.000Z</published>
...
I want to get the first tag in entry (tag:youtube.com, 2008 ...).
After googling for some hours and looking through the GDataXML wiki, I'm clueless because neither XPath nor GData could deliver the right element.
My first guess is, they can't ignore the attributes in the feed and entry tags.
A solution using XPath would be great, but one in Objective-C is equally welcome.
You might be having an issue trying to get XPath to work because of the default namespace.
If you just want the first tag in entry, you can use this:
/*/*[name()='entry']/*[1]
If you want the first id specifically, you can use this:
/*/*[name()='entry']/*[name()='id'][1]
Also if you can use XPath 2.0, you can skip the predicate entirely and use * for the namespace prefix:
/*/*:entry/*:id[1]
I would like to change the href attributes of the link tags that have the following attribute :
rel="apple-touch-icon-precomposed"
Does anyone know how to achieve that ?
Thank you
Ext.select can be used to search for DOM elements. To understand how to select elements in the DOM, one may have a look at jQuery Selectors documentation.
Ext.dom.Element.set can then be used to change the href attribute. Note that even if Ext.select returns a collection, all methods of Ext.Element can be used on the collection.
In short, this gives something like this:
Ext.select("a[rel='apple-touch-icon-precomposed']").set({href: 'my-other-link.html'});
How to access a form variable using JSTL ?
e.g.
<html:text property="abc" ... />
<c:out value="${abc}"/>
abc is always blank, even though I have value set by action sending to this page.
If you refer with ActionForm, you can retrieve the value. "abc" is one of the property of ActionForm(you created) which will be available in request scope as it has been set in ActionServlet during processing request.
So get the value like this, suppose your ActionForm is 'TestForm', then retrieve as ${TestForm.abc} or <c:out value="${TestForm.abc}"/>
How do you display data in a 'textarea' using struts application,
This is my code:
<html:textarea property="comments" </html:textarea>
<bean:write name="FormBean" property="comments"/>
where FormBean is my beanclass and comment is a property in beanclass.
But I cannot get it too work.
Thanks in advance for your help.
If you use Struts action forms and you have the html:textarea tag inside your html:form tag (this tag is only valid when nested inside a form tag body) then the following code is all you need:
<html:textarea property="comments" />
Don't know what you are trying to do with bean:write but if you want to display that inside your html:textarea I'm not sure you can. The property attribute is mandatory for the html:textarea tag and will use that as the content.
