Thanks for your explanations. Now I see that something as
function displayTiddler(title,pos){
var story=$tw.wiki.getTiddler("$:/StoryList");
var text=story.fields["text"].split("\n");
if(text.indexOf(title)===-1) {
text.splice(pos,0,title);
$tw.wiki.addTiddler({title:"$:/StoryList",text:text.join("\n")})
}
}
seems to work quite well. I doubt it's the best solution for my initial
question but
I'm not a javascript guru and a real understanding of TW5 internals is not
so easy for me.
