[tw] Re: need help using variables and custom fields in pagewise FET
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?

So, eliminate the global entirely, and then write the 'button' code to
look something like this:

window.fetStartIndex = c;

var c=store.getValue(tiddler,vc)+window.fetItemsPerPage;
store.setValue(tiddler.title,versecount,c);
window.fetStartIndex = c;
story.refreshTiddler(context.viewerTiddler.title,null,true);
});
(note: untested code)
enjoy,

I've tried this in a more resent version (2.7.1) but can't make it work. I get 'tiddler.title' is null or not an objekt.

It doesn't do anything now when you click on the buttons :-( Actually, it does do something... it causes a program error! Look at the ToolsError Console (you may have to scroll to bottom). You should see an error that says: parseint is not defined I'm certain I put exactly what you said. not *exactly*... I wrote: parseInt(...), you wrote parseint(...).

Thanks for your patience Eric, It works now... I swear I looked at the two side-by-side ten times!

[tw] Re: need help using variables and custom fields in pagewise FET
Thank you Eric for explaining that about the global variables and the
fact that fields have to all be lower case.
Your code does kind of work, but its adding as text, not as math, e.g.
if I start with versecount of 0, then press the button, the
versecount (and thus the window.fetStartIndex) becomes 015, then
01515.
Is there a way to indicate that it should all be in math?
Thanks for your help,
-Dave
