Generate dynamic id’s for struts html tags

Posted: September 23rd, 2008 | Author: Nischal Shetty | Filed under: Struts | Tags: , , , , | 7 Comments »

Do you use struts tags to generate html content? If yes, then sooner or later you’ll come across a scenario where you would generate html elements with the same name but would need different id’s for each element. I faced a similar predicament recently. I had no other option but to use scriptlets to generate id’s for the html elements. However, I soon found out using scriptlets within the struts html tags isn’t really straight forward.

Here’s the code I tried in my first attempt:

<%int i=0;%>

//iteration logic here

<html:text property=”example” styleid=”example<%=i%>”>

Well, if you write the code as shown above, the html code generated would be :

<input type=”text” name=”example” id = “example<%=i%>”>

and not

<input type=”text” name=”example” id=”example0″>

To get the expected result, i.e. for the scriptlet to work inside the struts html tag, write as below:

<html:text property=”example” styleid=’<%=”example”+i%>’

That’s it. If any of you ever find out a way to generate different id’s for html elements with the same name using strtus tags exclusively then do let me know :)

    I can generate text boxes dynamically ok.. List is coming from query in DB. I am not sure how to write code in submit button in action form which will save back result to database.

    What would be code in action form to read all values?
