Hi I am using s:url tag for making a url, I need it to paginate my jsp to several pages.
So I need to send next or previous when we click on next or previous link. But when I click on Previous it shows me url on address bar like someAction?previuos=prev then I click on Next it displays someAction?previuos=prev&Next=Next when I only need someAction?Next=Next.
I have given different names to the url as for Previous link <s:url name="urlPrev"> and for next <s:url name="urlNext">
I don't how to differentiate them. What is wrong in my code?
The <s:url/> tag should default to the current action, without any parameters. You should just be able to say in your page:
<s:url>
<s:param name="Next" value="'Next'"/>
</s:url>
<s:url>
<s:param name="Previous" value="'Previous'"/>
</s:url>
Note that the <s:a/> tag behaves much like the tag excepting that it produces an html anchor of course so put the link name in the body. This should solve your tag issues...
Just to point out paging is roughly done on web sites by passing parameters which account for start_index and number_of_records_per_page. The "Next" button then simply adds number_of_records_per_page + 1 for the value of start_index for next. To decrement subtract number_of_records_per_page. By standardising the names all list based actions become easier to write.
Consult http://struts.apache.org/2.3.1.2/docs/tag-reference.html for use of these tags (one thing to note is the name parameter is not listed as a property for the url tag).

Lets say we have added this shortcode to our website:
[products columns="3" attribute="season" terms="warm" orderby="date"]
You know it shows all products with attribute "warm", but when we click on each of them, on single product page the "warm attribute" is not selected.
It will be more convenient for user to see that attribute is already selected. How we can do that?
Can we add any function to add something like ?attribute_pa_season=warm at the end of URLs?
Many thanks for suggestions:)
I search the documentation but I didn't know exactly how to call that.
I have a template Index2Name that return a name based on an index.
I'm trying to use that name in a link:
[[Articles/{{Index2Name|0001}}|{{Index2Name|0001}}]]
or
Image:Big-0001.png|link=Articles/{{Index2Name|0001}}|''{{Index2Name|0001}}''
In the last example, the name is printed but the link doesn't work. (In gallery element)
It doesn't work. The value from the template is printed but it is not converted to a link.
How can I make this works? And does this have a name? (For future reference)
EDIT: Index2Name is a simple switch returning a few words depending of the id. Since I'm using subpages I only want the name to appear (Example: MyArticle) but the link is Articles/MyArticle
Could you clarify exactly what you want to happen please. (Where you want to link and how you want it to look).
But for example if you use:
[[Image:Big-0001.png|''{{Index2Name|0001}}'']]
It will link to the page Image:Big-0001.png with the link text being the output of:
''{{Index2Name|0001}}''
Or if you use:
[[Image:Big-001.jpg|link=Articles/{{Index2Name|0001}}]]
The image, when clicked, will redirect you to the output of:
{{Index2Name|0001}}
Alright, so I'm pretty new to Spring, but I was asked to resolve a bug. So in our application, we have a page that queries a database based on an id. However, not all entries are unique to the id. The id and date pair, on the other hand, do define unique entries.
So this page takes in an id. If there is only a single entry related to this id, everything works fine. However, if there are multiple entries, the page displays a radio button selection of the various dates that pertain to that id. We use something like:
< form:radiobutton id="loadDate" path="loadDate" value="${date}" label="${date}" />
Later on the same page, we want to display the data for that option. As part of it, we display the date of that selection:
< form:input id="aiLoadDate" path="loadDate" maxlength="22" size="22" class="readonly" readonly="true"/>
The problem is that when this happens, the variable (or bean? I'm not quite sure about Spring yet..) loadDate (a string) ends up being the same date twice, seperated with a comma. I'm guessing the problem here is the "path="loadDate"" that is common to both lines.
Instead of appending the date to the already existing one like a csv, I'd like it to overwrite the current entry intead. Is there a way to do this?
Spring is not the direct cause of your problem. When the elements of an HTML form are submitted, each element will appear in the request as a name=value pair. If two or more elements in the form have the same name (not id, name attribute) then those elements appear in the request as name=value,value (with one value per element with a duplicated name).
Option 1: stop using an input as a display element. Just display the date in a span (or div or paragraph or what ever). If you want the look of an input box (border, etc.) use CSS to create a class that has the look you want and attach the class to the span (or div or paragraph, etc) in which you display the date.
Option2: continue using an input as a display element. Disabled input elements are not added to the request when the form is submitted. in the form:imput set disabled="true".
I have a simple HTML page with an Unordered list. Is it possible to have an input field where you could add more to the list and it would be saved after you submitted it. What I would like to add would be the content inside of an <li> tag as well as the <li> tags themselves.
Thanks,
Here is a jsfiddle with a demo of what I think you want to achieve: http://jsfiddle.net/mvJNq/25/
Note that I can not answer as to how you should do this on the server, as that depends on how your serverside code, database etc is set up. However, if all you want is to display it as HTML and not have it saved as the user navigates away, you won't need the Submit button at all - then you just need the "Add" functionality.
Yes, it is possible - no, it will not be pretty. Here is what you would do:
create your base form with any default list items/inputs
use jQuery/JavaScript to bind an event handler to a button that you click when you want to add another item (alternatively, you could skip this step and just have another item appear by default)
on your event (be it checking that all input boxes have user-entered text, or the click event in step two) add another list item using jQuery.append(...)
ensure that you have a hidden input field to be used as a "counter" to keep track of the total number of list items and increment the value of this counter each time you add a new list item (note: you may need to use the ParseInt() method, depending on how you design the code for this field)
the page that is receiving the form's inputs should first read the hidden field so that it knows how many items to add, and then you should loop through the items (for or while loop) to add them correctly
Note: I don't know what Server-Side language you are using to handle receiving the form so step 5 is a fairly generic and universally viable option
Sure, it's possible.
The complexity of this comes in when you want to "save" the items. If the user leaves the page and comes back later will that data be available? If so, you will need a database like mySQL or similar. The li tags can be stored as well, but why?
If you just need that information available in that session you can store in a JavaScript variable and have it loop through the variable and spit them out as <li>'s
If you did want to use an add button instead of submit:
$('#addButton').click(function(){
var savedContent = $('#input').val();
}
To create + insert the <li>you can use javascript to create the element and append it to the ul. If you have more than one ul change the index:
var content = document.createElement('li');
content.innerText = savedContent;
document.getElementsByTagName('ul')[0].appendChild(content);
If for some reason it were mandatory to associate a <button> with more than one value, is there a good way to do it? For example ...
CSV:
<button value="Lancelot,Grail,blue">Answer</button>
JSON:
<button value="{'name':'Lancelot','quest':'Grail','color':'blue'}">Answer</button>
In the absence of a good way to do it, is there a traditional way?
Edit: another use case
Server M, the producer of the HTML, knows the user's current location and favorite genres, movie names, nearest theater, and next showtime. Server F knows how to query various 3rd party servers about how to get from point A to point B in order to arrive by time T. The user knows only the movie names: click Drag Me to Hell, and get the route. Server M could generate a form for each movie, with a single button showing the name of the movie and multiple hidden fields with the start and end locations and desired arrive-by time, but that would require a lot of repeated code. Every one of these one-button mini-forms would have the same method and action and the same hidden input field structure. Styling would be a collection of mini-forms rather than a collection of buttons, so FIELDSET and LEGEND are unavailable (because HTML forbids nested forms). Putting the parameters into the button's value attribute would be much tidier.
Well if you have to have a button element, why not use JavaScript to set a bogus property:
$('mybutton').compoundValue = { ... json ... };
and then reading the 'compoundValue's during form submit, etc.
Though really you might want to consider a group of checkboxes or some other form bits for what you're trying to accomplish.
