How to choose a value of a HashMap in select Struts2?
问题 I ran into a problem with Struts2. I have a HashMap<String, Integer> that I use in a form with a select to choose name and corresponding id to that name. HashMap iterates and populates my <select> list with names. I only need an id to pick. How do I pick an id/value instead of a name/key? companyMap is a HashMap , where <String, Integer> or key, value. companyName is a String. <s:select label="Pick the company name" headerKey="-1" headerValue="Select Company name" list="companyMap.keys" name
