165 <p>The jalviewLite applet's application programming interface (API) includes two components. A <a href="javascript/jalview.js">JalviewLite Javascript Library</a> and the <a href="#api">public methods on the JalviewLite applet</a>.
169 <li>Unfortunately Javascript - Java communication is not possible
170 using Internet Explorer or Opera on Macs. Please use Safari or
172 <li>If more than one Jalview window is open, Jalview returns the
173 alignment in the active window, unless you provide an AlignFrame
174 object reference.</li>
175 <li>The alignment output format can be either Fasta, PFAM, Clustal,
176 MSF, PIR, or BLC.</li>
177 <li>When referring to the Jalview applet in javascript, you must
178 either give Jalview a name in the applet tag or use the document.applets index.</li>
179 <li>When creating javascript functions that are called by jalviewLite (e.g. the <em>oninit</em> parameter, or any mouseOver, selection or structureListener handlers), ensure they complete very quickly, and do not access any jalview API methods that might result in more javascript calls (this which will cause your browser to hang). If you need to do this, we suggest that jalviewLite callbacks are used to add new javascript events to a queue (e.g. using a Jquery timer callback) to avoid any concurrency issues.
183 <h1>JalviewLite's Javascript API</h1></a>
184 <p>The following public methods on the jalviewLite applet are available to be called from javascript:</p>
