流星大火renderWithData

Question

I'm trying to render a Template via Blaze. So normally I call

Blaze.render(Template.xxx,$("#parentnode")[0]);

which works fine.

Now I want to differentiate in the Template xxx who rendered it. So I want to pass a variable to the Template which I can use to decide who it was. I tried

Blaze.renderWithData(Template.xxx,{test:"value"},$("#parentnode")[0]);

And then tried to access the Data in

 Template.xxx.onRendered(function(){console.log(this.test)});

which logged "this.test is not defined blabla". How can I pass data correctly and access it?

Thanks for your answers and have a good one!

Answer 1

According to meteor docs it is not possible to access context object in onRendered callback. The this keyword refers to the template instance and does not contain any stateful data. What you can do is to render the data properties inside DOM nodes (in hidden elements if you don't want to display them). You can access the DOM from onRendered function.

Template.currentData() is available when the template is rendered so try using Template.currentData() instead of this and it should work:

Template.xxx.rendered = function() {
  var _this = Template.currentData();
  console.log(_this.test)
};
