AFAIK Struts2 is server side only whereas JavaScript is client side. Thus you can't create/fill struts tags using JavaScript (unless you execute it on the server side which wouldn't make sense IMHO).

@saptak: How can I do what? Your question doesn't make sense. The JSP code exists only at server-side. JavaScript only sees the generated HTML. What do you want to change in the HTML?

Sorry, My problem is how can I set hidden field value as url param value?

JB Nizet Over a year ago

@saptak: URL of what? A link? A form action? Forget about the JSP and look at the generated HTML in the browser. What would you like to change in this HTML code using JavaScript?

URL of a link code is <a href="<s:property value="#productTag"/>"/>Click Here</a>.

<s:property value="#productTag"/> that's not an url. What does it look like in the generated HTML? You don't have struts tags there, unless your struts is not working at all. - In what way should that be dynamic? Please add more information to your question (not as a comment here as it is harder to format, read and find for others).
