How to use html:link and javascript:window.open

[Sandeep Ghosh]

Hi Friends,
I am trying to open a link on a pop up window and content will be fetched from database. For this I am writing
<html:link href="javascript:window.open('/man/imagedisplay.do','','toolbar=no, width=350,height=250,resizable=1, scrollbars=1'); void('');" paramId="postid" paramName="postdetail" paramProperty="postID" >See original image</html:link>
It is giving scripting error.
When I am trying open link in just differnt window by this code it working fine
<html:link page="/man/imagedisplay.do" paramId="postid" paramName="postdetail" paramProperty="postID" target="_blank" >See original image.</html:link></td></tr>
Could anybody tell me where I am going wrong.
Thanks in adv.

Ok I managed to do this much. When I am putting hard code value of primary key like this
<html:link href="javascript:window.open('/MyWeb/man/imagedisplay.do?postid=167','Original Image','toolbar=no, width=450,height=350,resizable=1, scrollbars=1');void('');">See original image</html:link>
it is working fine.
but I want my pk to be place dynamically. So I am trying this one
<html:link href="javascript:window.open('/MyWeb/man/imagedisplay.do?postid=<bean:write name="postdetail" property="postID" />','Original Image','toolbar=no, width=450,height=350,resizable=1, scrollbars=1');void('');">See original image</html:link>
Now JSP is giving this exception
[ServletException in:/tiles/postdetail.jsp] /tiles/postdetail.jsp(43,111) jsp.error.attribute.noequal' org.apache.jasper.JasperException: /tiles/postdetail.jsp(43,111) jsp.error.attribute.noequal at org.apache.jasper.compiler.DefaultErrorHandler.jspError(DefaultErrorHandler.java:94) at org.apache.jasper.compiler.ErrorDispatcher.dispatch(ErrorDispatcher.java:417) at org.apache.jasper.compiler.ErrorDispatcher.jspError(ErrorDispatcher.java:126) at
...
...

I am also running into problem when I am trying html:rewrite the url.
Could anybody please help me with correct solution

You can't nest tags like that. A couple of ways you can make it work. First, I would refactor a bit and make a JavaScript function to encapsulate the popup window creation:

<script type="text/javascript" language="JavaScript">
function openWindow(param) {
   var url = "/MyWeb/man/imagedisplay.do?postId=" + param;
   window.open(url, ...);
}
</script>

1. In a scriptlet, put together the desired javascript expression string then use a JSP expression to plug it into the html:link

<% String page = "javascript:openWindow(" + postId + ")"; %>
<html:link page="<%= page %>" ... >

or
2. Use plain HTML link markup and insert the bean:write in the appropriate place.

<a href="javascript:openWindow(<bean:write name="postdetail" property="postID" />)">

Hi Junilu,
Thanks a lot .It is working.
Another problem how could I encode my URL in javascript .I am trying this
function openWindowTest(param) {
var url = <%=response.encodeURL("/man/imagedisplay.do?postid=")%>+param;
window.open(url,'Original Image','toolbar=no, width=450,height=350,resizable=1, scrollbars=1');
}
but is giving javascripting error.

I think you left out some quotes:
function openWindowTest(param) {
var url = "<%=response.encodeURL("/man/imagedisplay.do?postid=")%>" + param;
window.open(url,'Original Image','toolbar=no, width=450,height=350,resizable=1, scrollbars=1');

Hi ,

I am also facing the same problem as mentioned. I want to open a new window by appending a paramID to the URL.
From the given code snippet, I did not understand what should I put in place of bean name in the following snippet:
<bean:write name="bean name " property="postID">

Please help.

Hi Friends,
I also faced the same problem. I have a dimple solution for this.

1<display:column media="html">
2 <c:set var="link">'<html:rewrite action="/WsMasterUseCase/SearchGroupAndMapBeneficiaryMapBeneficiary"/>?groupSystemId=${row.groupSystemId}'</c:set><nobr>
3 <html:link href="javascript:window.open(${link},'','width=1000,height=550,scrollbars=yes');void('');" styleClass="buttonLink"><bean:message key="map.unmap.beneficiary"/>
4 </html:link></nobr>
5 </display:column>

Here line #2 is using for setting the url, with dynamic Id.
Please try this
