Hello Klaus I think that it should be possible to do what you want without using eval(), which is usually not recommended by javascript gurus.
The variable is indeed an object and not a string, but that is what Jmol expects. There may be a problem when the variable has not been defined beforehand; not sure if it will be your case. The trick in that case is to define it first like myJmol = "myJmol" Better: I made a page with your functions and it is working as desired when I use it like this <input type="button" value="test A" onClick="KS_AtomeHervorheben(A)"> but I get the error when I use it like this: <input type="button" value="test A" onClick="KS_AtomeHervorheben('A')"> So the issue would be you must pass the object, not the name. If you don't want to write the object manually, like I did, I suggest that you use the following instead of eval; one way to refer to objects ny their name is to use window[objectname] That would allow for example this to apply to all Jmol objects named A, B, C, D: function setAll() { for (i=65; i<69; i++) { KS_AtomeHervorheben( window[String.fromCharCode(i)] ) } } <input type="button" value="test all" onClick="setAll()"> > However, one more problem remains.

Which > files (beside the old Jmol.js) do I have to include? It is compatible, but you must be moving to new syntax also for the Java mode. You must not use Jmol.js any longer, instead just change: Info.use = 'java' Info.use = 'html5' // default ------------------------------------------------------------------------------ Mobile security can be enabling, not merely restricting.
