1 Put the following in the superclass for your components:
2
3 {{code}}
4
5 private String anchor;
6
7 public void appendToResponse(WOResponse response, WOContext context) {
8
9 if (anchor != null) {
10 response.setHeader(context.componentActionURL() + "#" + anchor, "location");
11 response.setHeader("text/html", "content-type");
12 response.setHeader("0", "content-length");
13 response.setStatus(302);
14 anchor = null;
15 } else {
16 super.appendToResponse(response, context);
17 }
18 } // appendToResponse
19
20 public String getAnchor() {
21 return anchor;
22 }
23 public void setAnchor(String s) {
24 anchor = s;
25 }
26
27
28 {{/code}}
29
30 In the component where we want to use an anchor you just put in
31
32 {{code}}
33
34 <a name="myanchor"></a>
35
36 {{/code}}
37
38 and something like the following in the code where we want to jump to this anchor:
39
40 {{code}}
41
42 protected WOComponent doSometingAndJumpToAnchor() {
43 // do something :)
44 setAnchor("myanchor");
45 return null;
46 }
47
48 {{/code}}
