I have a scenario where I would like to create dynamic template elements that will be used with Polymer's dom-repeat.
My current prototype is the following (JSbin demo):
var domRepeat = document.createElement('template', 'dom-repeat');
domRepeat.items = ['a', 'b', 'c'];
var div = domRepeat.content.ownerDocument.createElement('div');
div.innerHTML = '[[item]]';
domRepeat.content.appendChild(div);
document.body.appendChild(domRepeat);
Polymer.dom.flush();
However, this does not work as intended. The output is:
[[item]]
[[item]]
[[item]]
rather than:
a
b
c
Since the [[item]] is printed out 3 times, I guess the dom-repeat itself works, but the data binding does not.
Plot twist: but if I change the example from dom-repeat to dom-bind, then the data binding does work. Changed example, inspired by this answer (JSBin demo):
var domBind = document.createElement('template', 'dom-bind');
domBind.item = 'Hello World!';
var div = domBind.content.ownerDocument.createElement('div');
div.innerHTML = '[[item]]';
domBind.content.appendChild(div);
document.body.appendChild(domBind);
Polymer.dom.flush();
The output is Hello World!, as expected.
Any ideas on how to get the first example to work?
