Eric,
Using your sample as is, with the parseInt fix, makes the buttons won't do
anything when clicked. I've checked the error console and no error listed.
However, this code is behaving strangely:
function getHeader(context,count)
{
if (!window.fetStartIndex || window.fetStartIndex < 0)
window.fetStartIndex = 0;
// ensure not to page behind the last page
if (window.fetStartIndex >= count)
window.fetStartIndex =
Math.min(Math.max(window.fetStartIndex-window.fetItemsPerPage,0),count-1);
createTiddlyButton(context.place,"<",null,
function(e) {
// modified according to
https://groups.google.com/forum/#!topic/tiddlywiki/0Q3zVhGK7Os
var c =
parseInt(store.getValue(tiddler,"local_count")) - window.fetItemsPerPage;
store.setValue(tiddler.title,"local_count",c);
window.fetStartIndex = c;
story.refreshTiddler(context.viewerTiddler.title,null,true);
});
createTiddlyButton(context.place,">",null,
function(e) {
// modified according to
https://groups.google.com/forum/#!topic/tiddlywiki/0Q3zVhGK7Os
var c =
parseInt(store.getValue(tiddler,"local_count")) + window.fetItemsPerPage;
store.setValue(tiddler.title,"local_count",c);
window.fetStartIndex = c;
story.refreshTiddler(context.viewerTiddler.title,null,true);
});
var startNo = window.fetStartIndex+1;
var endNo =
Math.min(count,window.fetStartIndex+window.fetItemsPerPage);
return "("+startNo+" - "+endNo+ " of "+ count + "
items)\n{{clear{\n}}}";
}
The buttons will change page only after clicking on them several times.
Sometimes 4 clicks is necessary to change page, sometimes 2, and so on. Do
you know what's going on?
