<p>The PyMOL JavaScript API re-exposes PyMOL's Python programming
|
||
|
|
interface directly to the JavaScript layer in an object-oriented way.</p>

<pre>
|
||
|
|
var pymol = new PyMOL(); // create PyMOL object instance for server of this page

|

|
|
var cmd = pymol.cmd; // assign a global symbol for the PyMOL cmd API
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<pre>
|
||
|
|
<a href="javascript:void(0)" onclick="cmd.load('$PYMOL_PATH/test/dat/pept.pdb')">cmd.load('$PYMOL_PATH/test/dat/pept.pdb)</a>
|
||
|
|
|

|
<a href="javascript:void(0)" onclick="cmd.zoom('pept///1/',0,0,0,1)">cmd.zoom('pept///1/',0,0,0,1)</a>
|

|

|
|
<p>This eliminates the need for encoding your PyMOL commands as URL query
|
||
|
|
strings and makes it possible to write JavaScript programs in your web page
|
||
|
|
which control PyMOL in much the same way Python programs do.</p>
