copied!<p>There are a couple of different ways to have portlets talk with each other. Most are covered under the documentation of <a href="http://www.liferay.com/community/wiki/-/wiki/Main/Inter-portlet+communication;jsessionid=916639CD65CDFFA477343D48BCCAEEC4.node-2" rel="nofollow">IPC</a>'s and the <a href="http://www.liferay.com/community/wiki/-/wiki/Main/Client-side+Inter-Portlet+Communication;jsessionid=6CACC5A9C08E957058936D3368E3C24F.node-2" rel="nofollow">descendant</a> <a href="http://www.liferay.com/community/wiki/-/wiki/Main/Eventing+and+Shared+Render+Parameters;jsessionid=6CACC5A9C08E957058936D3368E3C24F.node-2" rel="nofollow">pages</a>.</p> <p>In your case, you should really look at the <a href="http://www.liferay.com/community/wiki/-/wiki/Main/Client-side+Inter-Portlet+Communication;jsessionid=6CACC5A9C08E957058936D3368E3C24F.node-2" rel="nofollow">client-side</a> page:</p> <p>With your basic structure</p> <pre><code><a href="javascript:void(0)" class="comm-demo">demo[number]</a> </code></pre> <p>You would have this JS on the "transmitter portlet":</p> <pre><code>// you may need to have jQuery instead of $. Liferay may have its own // $ function which jQuery shouldn't mess with. $( function () { $('a.comm-demo').click( function(event) { var txt = $(this).next().val(); // demo<number> Liferay.trigger('click', {text: txt}); return false; }); }); </code></pre> <p>Then on the "receiving portlet(s)":</p> <pre><code> Liferay.bind( 'click', function(event, data) { var txt = data.text; // this will set all class-of-fields to have the text // "demo<number from above>Portlet" $('.class-of-fields')[0].html(txt + "Portlet"); // I believe there is a way to minimize/maximize a portlet by // simulating a mouse click, but research would be needed to // confirm. }); </code></pre>
