Doubt regarding this.getTiddler

[Bala Chandra]

Say i store values in two tiddlers and i want to add those values through a javascript macro in tiddlywiki. So i tried the following, but it keeps showing that this.getTiddler is not a function. I would like to understand how to do it.

    exports.name = "add";

    exports.params = [{

        name: "var1"

    }, {

        name: "var2"

    }];

    exports.run = function(var1, var2) {

        var t1=$tw.utils.parseFields(this.getTiddler(var1).fields.text);

        var t2=$tw.utils.parseFields(this.getTiddler(var2).fields.text);

        var t3=t1+t2;

        return t3;

    }

})();

        var t2=$tw.utils.parseFields($tw.wiki.getTiddler(var2).fields.text);    // may do the trick

BUT .. I didn't test the code.

Hi,

I did also mess with your code... But forgot to remove the "Quote" marks. .. Have a closer look at my first reply!
