java - Iterating over hashmap in JSP in struts application -
I have a hashmap
object which I'm getting on a JSP page.
HashMap & LT; Integer, gift_product & gt; Gift_hm = New Hashmop & lt; Integer, gift_product & gt; (); Gift_hm.put (17, new gift_product ("doll", 67));
Now I have to repeat it and display the content on JSP. There are two fields in the Gift_product
category: names
and values
.
JSP should be output
serial number product name Price 17 Doll 67 67 How do I get it?
View the Strates Tag When running on a Hashmap, each entry is a java.util.Map key
and value
to get the key (Gift_product object) and the value (Gift_product object) in this example:
/ P>
First set the Hashket as a feature in your action class request.setAttribute ("gift_hm", gift_hum);
and then jsp:
& lt; Logic: iterate id = "mapEntry" name = "gift_hm" and gt; & Lt; Bean: defined id = "gift" name = "map entry" property = "value" & gt; & Lt; TR & gt; & Lt; Td> Bean: Write name = "mapinternal" property = "key" & gt; & Lt; / Td> & Lt; Td> Bean: writing name = "gift" property = "product name" & gt; & Lt; / Td> & Lt; Td> Bean: write name = "gift" property = "value" & gt; & Lt; / Td> & Lt; / TR & gt; & Lt; / Logic: recurrence & gt;
