html:link

[Chetan Pandey <cp...@bluesingapore.com>]

Hi All:

 

I have a <html:link> in the Title of a Table.

 

Clicking on it should arrange all Rows in ascending Order the first time and
descending order the next time and so on.

 

I tried the following:

 

<%

int sortOrder=0;

//<bean:definfe failed miserably

%>

 

<html:link action="myAction.do?function=sort?sortOrder='${sortOrder++}' "

Event Name

</html:link>

 

In which (sortOrder % 2 == 0) will determine how to modify the table.

 

This however failed as we are not allowed to use post-increment operator.

 

Can anyone recommend a better approach.

 

Thanks.

 

Chetan

a) The displayTag library can sort for you
b) you can only pass one parameter using html:link (unless you use a Map)
c) if "function" is a Dispatch method you could use javascript onclick event handler to submit to the "sort" method, passing the sortOrder parameter - then toggle it in your action and put the new value back on the request for next use.
