在Dart中如何使用setInnerHtml元素 <template> 标签？

Question

For example, I have a piece of code like this:

String_test="
<template>
<label> {{count2}}  SSSSSSSSSSSSSSSSSSSSSSSSS </label> 
<input id="input1" type='text' value='{{count2}}'>
</template>"

and I want to assign String_test to another element, like:

DivElement span2 = new Element.tag("div");
span2.setInnerHtml(String_test);
_content.nodes.add(span2);

However, the "< template >' tag is not recognized, nothing will show up.

NOTE: My purpose is to use setInnerHtml to dynamically add contents to the webpage with data-binding still OK.

Any ideas?

Thanks!

It appears that you are including raw html in your Dart program files. This is not how Dart works. Dart has code (kept in .dart files) that is referenced to via a tag in the HTML file. This very quick tutorial will show you how to do that: https://www.dartlang.org/docs/tutorials/connect-dart-html/

Templating is found in the Dart Polymer library. It is too long of a process to go into here but you can find a short tutorial at: https://www.dartlang.org/docs/tutorials/polymer-intro/

I would also mention that Angular comes in a Dart flavor and I find it more accessible than the Polymer libraries. The tutorials and documentation are also much better. Angular is a more comprehensive suite of libraries and it's tutorials can be found here: https://github.com/angular/angular.dart.tutorial/wiki
